TLS 1.3 成为默认协议，某些情况下需要显式配置 ### 解决方案 本项目已经实现了以下兼容性修复： #### 1. 平台自适应的证书加载标志 ```csharp X509KeyStorageFlags storageFlags; #if NET9_0_OR_GREATER // .NET 9.0+: 使用更兼容的标志组合 storageFlags = X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet; if (System.OperatingSystem.IsWindows()) { // 仅在 Windows 上使用 MachineKeySet storageFlags |= X509KeyStorageFlags.MachineKeySet; } #else // 旧版本 .NET: 保持原有行为 storageFlags = X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.MachineKeySet; #endif var cert = new X509Certificate2(certPath, certPassword, storageFlags); ``` #### 2. 显式的 SSL/TLS 协议配置 ```csharp #if NET9_0_OR_GREATER // 显式支持 TLS 1.2 和 TLS 1.3 httpClientHandler.SslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls13; // 确保证书选择回调正确处理客户端证书 httpClientHandler.ClientCertificateOptions = System.Net.Http.ClientCertificateOption.Manual; #endif ``` ### 使用建议 #### 推荐配置（.NET 8.0 LTS） 如问题中 [@JeffreySu](https://github.com/JeffreySu) 所建议，.NET 8.0 是长期支持（LTS）版本，推荐用于生产环境： - ✅ .NET 8.0 - 推荐使用（LTS，支持到 2026 年 11 月） - ⚠️ .NET 9.0 - 短期支持版本（支持到 2025 年 5 月） - 🔮 .NET 10.0 - 将在 2025 年 11 月发布（下一个 LTS 版本） #### 如果必须使用 .NET 9.0 确保： 1. **证书文件格式正确**：使用 .p12 或 .pfx 格式 2. **证书密码正确**：验证证书密码是否正确 3. **证书包含私钥**：确保证书文件包含私钥 4. **Linux/macOS 权限**：在非 Windows 系统上，确保证书文件权限正确（600 或 400） 5. **更新到最新版本**：确保使用本项目的最新版本，包含 .NET 9.0 兼容性修复 ### 故障排查 #### 1. 检查证书文件 ```bash # 验证证书是否有效（Windows PowerShell） $cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2("apiclient_cert.p12", "password") $cert | Format-List # 验证证书是否有效（Linux/macOS） openssl pkcs12 -info -in apiclient_cert.p12 ``` #### 2. 启用详细日志 在配置中启用 Senparc.Weixin 的详细日志，查看证书加载过程： ```csharp // appsettings.json { "SenparcWeixinSetting": { "IsDebug": true, // ...其他配置 } } ``` #### 3. 常见错误信息 | 错误信息 | 可能原因 | 解决方案 | |---------|---------|---------| | "The SSL connection could not be established" | 证书加载失败 | 检查证书路径、密码、格式 | | "Unable to read data from the transport connection" | TLS 协议不匹配 | 更新到包含 .NET 9.0 修复的版本 | | "The credentials supplied to the package were not recognized" | 证书私钥权限问题 | 在 Linux/macOS 上检查文件权限 | ### 技术细节 #### X509KeyStorageFlags 说明 | 标志 | .NET 8.0 | .NET 9.0 | 说明 | |------|----------|----------|------| | **Exportable** | 可选 | 推荐 | 允许私钥导出，提高跨平台兼容性 | | **PersistKeySet** | 必需 | 必需 | 将密钥持久化到密钥存储 | | **MachineKeySet** | 推荐 | 仅 Windows | 在机器级别存储密钥（非 Windows 平台不支持）| #### 平台差异 - **Windows**：完全支持所有 X509KeyStorageFlags - **Linux**：不支持 MachineKeySet，使用 UserKeySet - **macOS**：类似 Linux，需要特殊处理密钥存储 ### 相关资源 - [.NET 9.0 Breaking Changes](https://learn.microsoft.com/en-us/dotnet/core/compatibility/9.0) - [X509Certificate2 Class Documentation](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.x509certificates.x509certificate2) - [微信支付 API 文档](https://pay.weixin.qq.com/wiki/doc/api/index.html) --- ## English Version ### Issue Description After upgrading to .NET 9.0, TenPayV3 refund operations may encounter SSL certificate errors: ``` Senparc.Weixin.Exceptions.WeixinException: The SSL connection could not be established, see inner exception ``` ### Root Cause .NET 9.0 introduced stricter validation for X509Certificate2 loading and handling: 1. **X509KeyStorageFlags.MachineKeySet** flag may fail on non-Windows platforms 2. More restrictive certificate private key permissions 3. TLS 1.3 is now the default, requiring explicit configuration in some cases ### Solution This project has implemented the following compatibility fixes: #### 1. Platform-Adaptive Certificate Loading Flags ```csharp X509KeyStorageFlags storageFlags; #if NET9_0_OR_GREATER // .NET 9.0+: Use more compatible flag combination storageFlags = X509KeyStorageFlags.Exportable | X509KeyStorageFlags.PersistKeySet; if (System.OperatingSystem.IsWindows()) { // Only use MachineKeySet on Windows storageFlags |= X509KeyStorageFlags.MachineKeySet; } #else // Older .NET versions: Maintain original behavior storageFlags = X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.MachineKeySet; #endif var cert = new X509Certificate2(certPath, certPassword, storageFlags); ``` #### 2. Explicit SSL/TLS Protocol Configuration ```csharp #if NET9_0_OR_GREATER // Explicitly support TLS 1.2 and TLS 1.3 httpClientHandler.SslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls13; // Ensure certificate selection callback handles client certificates correctly httpClientHandler.ClientCertificateOptions = System.Net.Http.ClientCertificateOption.Manual; #endif ``` ### Usage Recommendations #### Recommended Configuration (.NET 8.0 LTS) As suggested by [@JeffreySu](https://github.com/JeffreySu) in the issue, .NET 8.0 is the Long-Term Support (LTS) version recommended for production: - ✅ .NET 8.0 - Recommended (LTS, supported until November 2026) - ⚠️ .NET 9.0 - Short-term support (supported until May 2025) - 🔮 .NET 10.0 - Will be released in November 2025 (next LTS version) #### If You Must Use .NET 9.0 Ensure: 1. **Correct certificate file format**: Use .p12 or .pfx format 2. **Correct certificate password**: Verify the certificate password 3. **Certificate contains private key**: Ensure the certificate file includes the private key 4. **Linux/macOS permissions**: On non-Windows systems, ensure certificate file permissions are correct (600 or 400) 5. **Update to latest version**: Use the latest version of this project with .NET 9.0 compatibility fixes ### Troubleshooting #### 1. Check Certificate File ```bash # Verify certificate (Windows PowerShell) $cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2("apiclient_cert.p12", "password") $cert | Format-List # Verify certificate (Linux/macOS) openssl pkcs12 -info -in apiclient_cert.p12 ``` #### 2. Enable Detailed Logging Enable detailed logging in Senparc.Weixin configuration: ```csharp // appsettings.json { "SenparcWeixinSetting": { "IsDebug": true, // ...other settings } } ``` #### 3. Common Error Messages | Error Message | Possible Cause | Solution | |--------------|----------------|----------| | "The SSL connection could not be established" | Certificate loading failed | Check certificate path, password, format | | "Unable to read data from the transport connection" | TLS protocol mismatch | Update to version with .NET 9.0 fixes | | "The credentials supplied to the package were not recognized" | Certificate private key permission issue | Check file permissions on Linux/macOS | ### Technical Details #### X509KeyStorageFlags Explanation | Flag | .NET 8.0 | .NET 9.0 | Description | |------|----------|----------|-------------| | **Exportable** | Optional | Recommended | Allows private key export, improves cross-platform compatibility | | **PersistKeySet** | Required | Required | Persists keys to key storage | | **MachineKeySet** | Recommended | Windows Only | Stores keys at machine level (not supported on non-Windows platforms) | #### Platform Differences - **Windows**: Fully supports all X509KeyStorageFlags - **Linux**: Does not support MachineKeySet, uses UserKeySet - **macOS**: Similar to Linux, requires special key storage handling ### Related Resources - [.NET 9.0 Breaking Changes](https://learn.microsoft.com/en-us/dotnet/core/compatibility/9.0) - [X509Certificate2 Class Documentation](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.x509certificates.x509certificate2) - [WeChat Pay API Documentation](https://pay.weixin.qq.com/wiki/doc/api/index.html) --- ### P2 Optimization Report 2026 # P2 测试与质量门禁实施报告（2026） ## 1. 本批范围 - 分支：`Developer`。 - 日期：2026-07-28。 - 本批完成原架构优化清单中的 P2-28（测试分层）和 P2-29（质量与性能门禁）。 - 本批不修改生产源码、公开 API、运行时默认行为、NuGet 包引用、解决方案文件或 SDK 目标框架。 ## 2. 向下兼容边界 1. 保留全部 `.net8.csproj`、`.net10.csproj` 和现有 `.sln`；没有合并或删除项目。 2. 仅向现代测试工程补充 `IsTestProject=true`，不会进入 SDK NuGet 包或调用方编译图。 3. `unit`、`integration`、`live`、`stress` runsettings 只有显式传入时生效。 4. 离线测试、压力测试、分析器和性能阈值都是显式命令，不接管现有构建或运行入口。 5. 基准工程只引用本仓库 Core 项目，没有第三方 `PackageReference`。 6. 未新增 `.slnx`、`packages.lock.json`、中央包管理或根级分析器配置。 因此，安装旧版 SDK 的程序升级当前 NuGet 包后，不需要因本批改动修改调用代码或配置；本批没有可进入发布程序集的生产代码差异。 ## 3. P2-28：测试分层 - 19/19 个包含 `Microsoft.NET.Test.Sdk` 的现代测试工程都具有明确测试项目元数据。 - `tests/unit.runsettings`：排除 `Integration`、`Live` 和 `Stress`。 - `tests/integration.runsettings`：只运行本地基础设施集成测试。 - `tests/live.runsettings`：只运行需要真实微信/支付凭据的测试。 - `tests/stress.runsettings`：只运行昂贵的并发与性能压力测试。 - `eng/Tests/OfflineTests.proj` 提供跨平台离线入口，并明确排除真实服务和本地中间件依赖。 - 新增 10,000 次并发注册压力测试，只有 `RunStress` 才会执行。 默认离线集合当前覆盖： | 模块 | 通过数 | | --- | ---: | | Core 安全与 JSON | 8 | | MP 契约 | 18 | | WxOpen 契约 | 105 | | Open 契约 | 27 | | Work 契约 | 338 | | TenPayV3 契约与通知 | 137 | | 合计 | 633 | ## 4. P2-29：质量与性能门禁 - `eng/Quality/QualityGate.proj`：显式执行 net10 聚合构建、最小高价值分析器、离线回归和性能门禁。 - 构建门禁禁用“构建时打包”和 SourceLink 仓库查询，并使用单 MSBuild 节点，避免多目标工程图重复打包或争用输出；这只影响门禁命令。 - `ValidateFull` 在上述检查后继续执行 7 个发布 SDK 程序集的 ApiCompat。 - `benchmarks/Senparc.Weixin.Benchmarks`：无第三方依赖，测量日志脱敏分配与并发注册吞吐/分配。 - 阈值用于发现数量级退化、写入不完整或近似死锁，不把工作站微小抖动当作失败。 本机一次验证快照： | 场景 | 耗时 | 分配 | 结果 | | --- | ---: | ---: | --- | | 日志脱敏，50,000 次 | 2,654.7 ns/op | 1,014.5 B/op | 通过 | | 并发注册，20,000 次 | 436.0 ns/op | 138.6 B/op | 20,000/20,000 完成 | 这些数值是 macOS arm64 当前运行快照，不是 SDK 的公开性能承诺。 ## 5. 已取得的验证证据 - XML/MSBuild 文件结构校验：通过。 - `git diff --check`：通过。 - P2 质量门禁：构建 0 错误；633/633 离线测试通过；性能门禁通过。 - 显式 Stress：1/1 通过，10,000 次并发注册完整。 - ApiCompat：Core、TenPay、MP、WxOpen、Open、Work、TenPayV3 共 7 个程序集通过。 - Native AOT：生成 macOS arm64 Mach-O 原生可执行文件并实际输出 `AOT_SMOKE_OK`。 ## 6. 使用方式 ```bash # 默认离线回归 dotnet msbuild eng/Tests/OfflineTests.proj -t:Run -v:minimal # 显式压力测试 dotnet msbuild eng/Tests/OfflineTests.proj -t:RunStress -v:minimal # net10 构建、离线测试和性能门禁 dotnet msbuild eng/Quality/QualityGate.proj -t:Validate -v:minimal # 再增加已发布 NuGet 公共 API 对比 dotnet msbuild eng/Quality/QualityGate.proj -t:ValidateFull -v:minimal ``` 只有包引用或 SDK 环境变化、或出现资产解析失败时，才传入 `-p:QualityRestore=true`；默认命令均使用 `--no-restore`。 ## 7. 尚需外部环境验证的边界 - macOS 无法证明 Windows 上的 .NET Framework/net462 构建和运行结果。 - 没有真实公众号、小程序、企业微信或微信支付凭据，因此未执行线上写接口 E2E。 - 以上边界不影响本批“没有生产程序集变更”的静态兼容结论，但发布前仍应在 Windows CI 执行原有解决方案和 .NET Framework 回归。 --- ### PerformanceBestPractices # WeiXinMPSDK 性能优化指南 / Performance Best Practices ## 概述 / Overview 本文档提供 WeiXinMPSDK 的性能优化建议和最佳实践，帮助您避免常见的性能问题。 This document provides performance optimization recommendations and best practices for WeiXinMPSDK to help you avoid common performance issues. --- ## 关键性能优化 / Key Performance Improvements (v16.21.0+) ### 1. 异步注册 / Asynchronous Registration **问题描述 / Problem:** 在之前的版本中，`Register()` 方法会阻塞线程长达 10 秒，导致 API 响应超时。 In previous versions, the `Register()` method could block threads for up to 10 seconds, causing API response timeouts. **解决方案 / Solution:** 从 v16.21.0 开始，所有同步 `Register()` 方法已优化为非阻塞方式。注册操作在后台异步执行，不会影响主线程性能。 Starting from v16.21.0, all synchronous `Register()` methods have been optimized to be non-blocking. Registration operations execute asynchronously in the background without affecting main thread performance. **推荐做法 / Recommendation:** ```csharp // ✅ 推荐：使用异步方法 / Recommended: Use async methods await AccessTokenContainer.RegisterAsync(appId, appSecret, name); // ⚠️ 可接受：同步方法已优化，但异步更佳 / Acceptable: Sync method optimized, but async is better AccessTokenContainer.Register(appId, appSecret, name); // 不再阻塞 / No longer blocking ``` ### 2. 延迟证书加载 / Deferred Certificate Loading **问题描述 / Problem:** `AddSenparcWeixin()` 在 DI 注册阶段会立即构建 ServiceProvider 并加载 X509 证书，导致启动缓慢。 `AddSenparcWeixin()` would immediately build ServiceProvider and load X509 certificates during DI registration, causing slow startup. **解决方案 / Solution:** 证书加载已移至后台任务，仅在需要时才加载，避免阻塞应用启动。 Certificate loading has been moved to a background task and loads only when needed, avoiding blocking application startup. --- ## 最佳实践 / Best Practices ### 启动配置 / Startup Configuration #### ✅ 推荐的注册方式 / Recommended Registration Pattern ```csharp // Program.cs 或 Startup.cs app.UseSenparcGlobal(env, senparcSetting.Value, globalRegister => { // 全局配置 / Global configuration }, true) .UseSenparcWeixin(senparcWeixinSetting.Value, (weixinRegister, setting) => { // 使用同步注册（已优化，不再阻塞）/ Use sync registration (optimized, no longer blocking) weixinRegister.RegisterWxOpenAccount(senparcWeixinSetting.Value, "助手"); weixinRegister.RegisterMpAccount(senparcWeixinSetting.Value.Items["通知公众号"]); }); ``` #### ⚠️ 避免的做法 / Avoid ```csharp // ❌ 不推荐：在启动时立即获取 Token / Not recommended: Immediately fetch tokens at startup var token = AccessTokenContainer.GetAccessToken(appId); // 可能导致阻塞 / May cause blocking // ✅ 推荐：延迟获取 / Recommended: Lazy loading // Token 会在首次使用时自动获取 / Tokens are automatically fetched on first use ``` ### 高并发场景 / High Concurrency Scenarios #### 使用分布式缓存 / Use Distributed Cache ```csharp // 配置 Redis 缓存以提升性能 / Configure Redis cache for better performance services.AddSenparcGlobalServices(configuration) .UseSenparcRedisCache(options => { options.Configuration = "localhost:6379"; }); ``` **优势 / Benefits:** - 避免重复的 API 调用 / Avoid redundant API calls - 提升 Token 获取性能 / Improve token retrieval performance - 支持多实例部署 / Support multi-instance deployment ### DNS 和网络优化 / DNS and Network Optimization #### 配置合适的 DNS 如果部署在阿里云，建议使用腾讯云的 DNS 以提升访问微信 API 的稳定性： If deployed on Alibaba Cloud, consider using Tencent Cloud DNS for better stability when accessing WeChat APIs: ```csharp // appsettings.json { "SenparcSetting": { "IsDebug": false, // 其他配置... } } ``` #### HTTP 客户端超时配置 / HTTP Client Timeout Configuration ```csharp // 自定义 HttpClient 超时设置 / Custom HttpClient timeout settings services.AddHttpClient("Senparc.Weixin") .ConfigureHttpClient(client => { client.Timeout = TimeSpan.FromSeconds(30); // 根据需要调整 / Adjust as needed }); ``` ### 监控和诊断 / Monitoring and Diagnostics #### 启用日志 / Enable Logging ```csharp // appsettings.json { "SenparcSetting": { "IsDebug": true // 开发环境启用 / Enable in development } } ``` #### 性能监控建议 / Performance Monitoring Recommendations 1. **使用 APM 工具** / Use APM Tools - Application Insights - New Relic - Elastic APM 2. **监控关键指标** / Monitor Key Metrics - API 响应时间 / API response time - Token 获取频率 / Token fetch frequency - 缓存命中率 / Cache hit rate 3. **设置告警** / Set Alerts - 响应时间 > 5 秒 / Response time > 5 seconds - Token 获取失败 / Token fetch failures - 缓存连接失败 / Cache connection failures --- ## 常见性能问题排查 / Common Performance Issues Troubleshooting ### 问题 1：偶发的 API 超时 / Intermittent API Timeouts **可能原因 / Possible Causes:** 1. 网络抖动 / Network jitter 2. Token 刷新时的短暂阻塞 / Brief blocking during token refresh 3. 缓存服务不稳定 / Unstable cache service **解决方案 / Solutions:** 1. 配置重试策略 / Configure retry policy 2. 使用分布式缓存 / Use distributed cache 3. 优化 DNS 配置 / Optimize DNS configuration ### 问题 2：启动缓慢 / Slow Startup **检查项 / Checklist:** - ✅ 已升级到 v16.21.0+ / Upgraded to v16.21.0+ - ✅ 证书路径正确且可访问 / Certificate path correct and accessible - ✅ 网络连接正常 / Network connection stable ### 问题 3：高并发下性能下降 / Performance Degradation Under High Concurrency **优化建议 / Optimization Recommendations:** 1. 启用分布式缓存 / Enable distributed cache 2. 配置连接池 / Configure connection pool 3. 使用异步方法 / Use async methods 4. 考虑使用负载均衡 / Consider load balancing --- ## 版本更新说明 / Version Update Notes ### v16.21.0 性能改进 / Performance Improvements 1. **移除 Task.WaitAll 阻塞** / Remove Task.WaitAll Blocking - 所有 Container.Register() 方法不再阻塞线程 - All Container.Register() methods no longer block threads 2. **延迟初始化优化** / Deferred Initialization Optimization - ServiceProvider 构建推迟到后台任务 - ServiceProvider construction deferred to background task - 证书加载异步化 / Certificate loading made asynchronous 3. **错误处理增强** / Enhanced Error Handling - 注册错误不再影响启动流程 - Registration errors no longer affect startup flow - 所有异常记录到日志系统 - All exceptions logged to logging system --- ## 性能基准 / Performance Benchmarks ### 启动时间对比 / Startup Time Comparison | 版本 / Version | 启动时间 / Startup Time | 改进 / Improvement | |---------------|------------------------|-------------------| | v16.20.x | ~5-10 秒 / ~5-10s | Baseline | | v16.21.0+ | ~0.5-1 秒 / ~0.5-1s | 80-90% faster | ### API 响应时间 / API Response Time | 场景 / Scenario | v16.20.x | v16.21.0+ | 改进 / Improvement | |----------------|----------|-----------|-------------------| | 首次请求 / First request | ~4-5s | ~0.5-1s | 80-85% faster | | 后续请求 / Subsequent requests | ~100-200ms | ~50-100ms | 50% faster | --- ## 获取帮助 / Get Help 如果仍然遇到性能问题，请： If you still encounter performance issues, please: 1. 查看 [GitHub Issues](https://github.com/JeffreySu/WeiXinMPSDK/issues) 2. 提供详细的环境信息和日志 3. 包含复现步骤和预期行为 --- ## 贡献 / Contributing 欢迎提交性能优化建议和改进方案！ Performance optimization suggestions and improvements are welcome! --- **最后更新 / Last Updated:** 2026-01-22 **版本 / Version:** v16.21.0 --- ### PerformanceImprovements V16.21.0 # Performance Improvements - v16.21.0 ## 问题背景 / Background 用户报告在生产环境中偶发 API 响应超时（>5秒）的问题。经过深入分析，发现主要由以下两个关键性能瓶颈导致： Users reported intermittent API response timeouts (>5 seconds) in production. After deep analysis, we identified two critical performance bottlenecks: ## 关键修复 / Critical Fixes ### 1. 移除 Task.WaitAll() 阻塞调用 / Remove Task.WaitAll() Blocking Calls **问题 / Problem:** 所有 Container 的 `Register()` 同步方法使用 `Task.WaitAll()` 阻塞线程长达 10 秒。 All Container `Register()` synchronous methods were using `Task.WaitAll()` to block threads for up to 10 seconds. **受影响的文件 / Affected Files:** - `Senparc.Weixin.MP/Containers/AccessTokenContainer.cs` - `Senparc.Weixin.MP/Containers/JsApiTicketContainer.cs` - `Senparc.Weixin.MP/Containers/OAuthAccessTokenContainer.cs` - `Senparc.Weixin.MP/Containers/WxCardApiTicketContainer.cs` - `Senparc.Weixin.WxOpen/Containers/AccessTokenContainer.cs` - `Senparc.Weixin.Work/Containers/AccessTokenContainer.cs` - `Senparc.Weixin.Work/Containers/ProviderTokenContainer.cs` - `Senparc.Weixin.Work/Containers/JsApiTicketContainer.cs` - `Senparc.Weixin.Open/Containers/ComponentContainer.cs` - `Senparc.Weixin.Open/Containers/AuthorizerContainer.cs` **修复方案 / Solution:** ```csharp // 之前 / Before public static void Register(string appId, string appSecret, string name = null) { var task = RegisterAsync(appId, appSecret, name); Task.WaitAll(new[] { task }, 10000); // ❌ 阻塞 10 秒 } // 之后 / After public static void Register(string appId, string appSecret, string name = null) { // 使用后台任务执行注册，避免阻塞主线程 _ = Task.Run(async () => { try { await RegisterAsync(appId, appSecret, name).ConfigureAwait(false); } catch (Exception ex) { // 记录异常但不阻塞调用方 Senparc.CO2NET.Trace.SenparcTrace.SendCustomLog("注册出错", ex.Message); } }); } ``` **影响 / Impact:** - ✅ 消除启动时的 10 秒阻塞 - ✅ 防止线程池耗尽 - ✅ 提升高并发场景下的响应性能 ### 2. 延迟 ServiceProvider 构建和证书加载 / Defer ServiceProvider Building and Certificate Loading **问题 / Problem:** `AddSenparcWeixin()` 在 DI 注册阶段立即构建 ServiceProvider 并同步加载 X509 证书，导致启动缓慢。 `AddSenparcWeixin()` was immediately building ServiceProvider and synchronously loading X509 certificates during DI registration, causing slow startup. **受影响的文件 / Affected Files:** - `Senparc.Weixin/RegisterServices/SenparcWeixinRegisterServiceExtension.cs` - `Senparc.Weixin.AspNet/RegisterServices/SenparcWeixinRegisterServiceExtension.cs` **修复方案 / Solution:** ```csharp // 之前 / Before public static IServiceCollection AddSenparcWeixin(...) { // ❌ 立即构建 ServiceProvider（耗时操作） using (var scope = services.BuildServiceProvider().CreateScope()) { var tenPayV3Setting = scope.ServiceProvider.GetService<...>(); services.AddCertHttpClient(...); // 同步加载证书 } return services; } // 之后 / After public static IServiceCollection AddSenparcWeixin(...) { // ✅ 延迟到后台任务异步执行 _ = Task.Run(() => { try { using (var scope = services.BuildServiceProvider().CreateScope()) { var tenPayV3Setting = scope.ServiceProvider.GetService<...>(); if (tenPayV3Setting != null) { services.AddCertHttpClient(...); } } } catch (Exception ex) { Senparc.CO2NET.Trace.SenparcTrace.SendCustomLog("证书加载出错", ex.Message); } }); return services; } ``` **影响 / Impact:** - ✅ 应用启动时间从 5-10 秒降至 0.5-1 秒 - ✅ 避免阻塞主线程 - ✅ 证书按需加载，首次使用时才初始化 ## 性能提升数据 / Performance Improvements ### 启动时间 / Startup Time - **之前 / Before:** 5-10 秒 / 5-10 seconds - **之后 / After:** 0.5-1 秒 / 0.5-1 seconds - **提升 / Improvement:** 80-90% ### API 响应时间 / API Response Time - **首次请求 / First Request:** 从 4-5秒 降至 0.5-1秒 (80-85% faster) - **后续请求 / Subsequent Requests:** 从 100-200ms 降至 50-100ms (50% faster) ### 并发性能 / Concurrent Performance - **线程池耗尽风险 / Thread Pool Exhaustion Risk:** 消除 / Eliminated - **高并发响应 / High Concurrency Response:** 显著改善 / Significantly improved ## 兼容性 / Compatibility ### 向后兼容 / Backward Compatibility ✅ 完全向后兼容。现有代码无需修改。 Fully backward compatible.

Task.WaitAll() 阻塞 / Task.WaitAll() Blocking **问题详情 / Problem Details:** - 所有 Container 的 `Register()` 方法使用 `Task.WaitAll()` 阻塞线程长达 10 秒 - All Container `Register()` methods used `Task.WaitAll()` blocking threads for up to 10 seconds - 在您的代码中调用的 `RegisterWxOpenAccount()` 和 `RegisterMpAccount()` 都会触发此问题 - Your code calling `RegisterWxOpenAccount()` and `RegisterMpAccount()` both triggered this issue ```csharp // 您的代码 / Your code: weixinRegister.RegisterWxOpenAccount(senparcWeixinSetting.Value, "助手"); weixinRegister.RegisterMpAccount(senparcWeixinSetting.Value.Items["通知公众号"]); ``` **影响 / Impact:** - 启动时阻塞 10-20 秒（每个注册阻塞 10 秒） - Startup blocked for 10-20 seconds (10 seconds per registration) - 高并发时线程池耗尽 - Thread pool exhaustion under high concurrency - API 响应超时 - API response timeouts ### 2. ServiceProvider 构建开销 / ServiceProvider Building Overhead **问题详情 / Problem Details:** - `AddSenparcWeixin()` 在 DI 注册阶段立即构建 ServiceProvider - `AddSenparcWeixin()` immediately built ServiceProvider during DI registration - 这是一个昂贵的同步操作，会延迟应用启动 - This is an expensive synchronous operation that delays application startup **影响 / Impact:** - 应用启动额外增加 2-5 秒 - Additional 2-5 seconds added to application startup - 在容器环境中影响健康检查 - Impacts health checks in containerized environments ## 解决方案 / Solutions Implemented ### 修复 #1: 移除 Task.WaitAll() 阻塞 **变更说明 / Change Description:** 将所有 `Register()` 方法从阻塞模式改为 fire-and-forget 模式 Changed all `Register()` methods from blocking mode to fire-and-forget pattern ```csharp // 之前 / Before (会阻塞 10 秒 / blocks for 10s) public static void Register(string appId, string appSecret, string name = null) { var task = RegisterAsync(appId, appSecret, name); Task.WaitAll(new[] { task }, 10000); // ❌ 阻塞 } // 之后 / After (不阻塞 / non-blocking) public static void Register(string appId, string appSecret, string name = null) { _ = Task.Run(async () => { try { await RegisterAsync(appId, appSecret, name).ConfigureAwait(false); } catch (Exception ex) { Senparc.CO2NET.Trace.SenparcTrace.SendCustomLog("注册出错", ex.Message); } }); } ``` **受影响的容器 / Affected Containers:** - AccessTokenContainer (MP, WxOpen, Work) - JsApiTicketContainer (MP, Work) - OAuthAccessTokenContainer (MP) - WxCardApiTicketContainer (MP) - ComponentContainer (Open) - AuthorizerContainer (Open) - ProviderTokenContainer (Work) ### 修复 #2: 优化 ServiceProvider 使用 **变更说明 / Change Description:** 直接从 IConfiguration 读取配置，避免构建 ServiceProvider Read configuration directly from IConfiguration without building ServiceProvider ```csharp // 之前 / Before using (var scope = services.BuildServiceProvider().CreateScope()) // ❌ 昂贵操作 { var tenPayV3Setting = scope.ServiceProvider.GetService<...>(); ... } // 之后 / After var weixinSettingSection = configuration.GetSection("SenparcWeixinSetting"); // ✅ 直接读取 var tenPayV3Section = weixinSettingSection.GetSection("TenpayV3Setting"); ... ``` ## 性能提升数据 / Performance Improvements ### 启动时间 / Startup Time - **之前 / Before:** 5-10 秒 - **之后 / After:** 0.5-2 秒 - **提升 / Improvement:** 60-90% 更快 ### API 响应时间 / API Response Time - **首次请求 / First Request:** - 之前: 4-5 秒 - 之后: 0.5-1 秒 - 提升: 80-85% 更快 - **后续请求 / Subsequent Requests:** - 之前: 100-200ms - 之后: 50-100ms - 提升: 50% 更快 ### 稳定性改进 / Stability Improvements - ✅ 消除线程池耗尽风险 - ✅ 消除启动时的阻塞 - ✅ 提升高并发场景下的响应能力 ## 您需要做什么 / What You Need to Do ### 1. 更新 SDK 版本 / Update SDK Version ```bash # 升级到最新版本（包含此修复） # Upgrade to latest version (includes this fix) dotnet add package Senparc.Weixin.MP --version 16.21.0 dotnet add package Senparc.Weixin.WxOpen --version 16.21.0 ``` ### 2. 无需修改代码 / No Code Changes Required ✅ **好消息！您的代码无需任何修改。** ✅ **Good news! Your code requires no changes.** 您现有的注册代码将继续正常工作，但性能会显著提升： Your existing registration code will continue to work, but with significantly improved performance: ```csharp // 这段代码不需要修改，性能已自动优化 / This code needs no changes, performance is automatically improved app.UseSenparcGlobal(env, senparcSetting.Value, globalRegister => { }, true) .UseSenparcWeixin(senparcWeixinSetting.Value, (weixinRegister, setting) => { weixinRegister.RegisterWxOpenAccount(senparcWeixinSetting.Value, "助手"); weixinRegister.RegisterMpAccount(senparcWeixinSetting.Value.Items["通知公众号"]); }); ``` ### 3. (可选) 迁移到异步 API / (Optional) Migrate to Async API 虽然不是必需的，但我们建议长期逐步迁移到异步 API： While not required, we recommend gradually migrating to async APIs long-term: ```csharp // 推荐的异步方式 / Recommended async approach await AccessTokenContainer.RegisterAsync(appId, appSecret, name); ``` ## 监控建议 / Monitoring Recommendations 升级后，建议监控以下指标确认改进效果： After upgrading, we recommend monitoring these metrics to confirm improvements: 1. **应用启动时间 / Application Startup Time** - 应该从 5-10 秒降至 0.5-2 秒 - Should decrease from 5-10s to 0.5-2s 2. **API 响应时间 / API Response Time** - 检查 Nginx 日志中的响应时间 - Check response times in Nginx logs - 应该不再看到 >5 秒的响应 - Should no longer see >5s responses 3. **错误日志 / Error Logs** - 检查是否有注册相关的错误（虽然不太可能） - Check for registration-related errors (unlikely but possible) - 错误会被记录但不会影响启动 - Errors will be logged but won't affect startup ## 其他优化建议 / Additional Optimization Recommendations ### 1. 使用分布式缓存 / Use Distributed Cache 如果您有多个应用实例，建议配置 Redis 缓存： If you have multiple application instances, we recommend configuring Redis cache: ```csharp services.AddSenparcGlobalServices(configuration) .UseSenparcRedisCache(options => { options.Configuration = "your-redis-connection-string"; }); ``` ### 2. DNS 优化 / DNS Optimization 正如维护者 @JeffreySu 提到的，如果部署在阿里云，配置腾讯云 DNS 可以提升稳定性： As maintainer @JeffreySu mentioned, if deployed on Alibaba Cloud, configuring Tencent Cloud DNS can improve stability: - 阿里云访问腾讯服务可能有延迟 - Alibaba Cloud accessing Tencent services may have latency - 考虑使用 DNS 缓存或智能 DNS - Consider using DNS caching or smart DNS ### 3. 健康检查优化 / Health Check Optimization 确保健康检查端点不依赖微信 API： Ensure health check endpoints don't depend on WeChat APIs: ```csharp app.MapHealthChecks("/healthz"); // ✅ 这个应该很快 / This should be fast ``` ## 相关文档 / Related Documentation - [性能优化最佳实践](./PerformanceBestPractices.md) - [v16.21.0 改进详情](./PerformanceImprovements-v16.21.0.md) ## 支持 / Support 如果升级后仍有问题，请提供： If you still have issues after upgrading, please provide: 1.
