NET9 CERTIFICATE COMPATIBILITY

.NET 9.0 证书兼容性说明 / .NET 9.0 Certificate Compatibility Guide

中文版本

问题描述

在升级到 .NET 9.0 后,TenPayV3 退款操作可能会遇到 SSL 证书错误:


Senparc.Weixin.Exceptions.WeixinException: The SSL connection could not be established, see inner exception
text

根本原因

.NET 9.0 对 X509Certificate2 的加载和处理进行了更严格的验证,特别是:

1. X509KeyStorageFlags.MachineKeySet 标志在非 Windows 平台上可能失败
2. 证书私钥权限要求更加严格
3. 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);

text
#### 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

text

使用建议

#### 推荐配置(.NET 8.0 LTS)

如问题中 @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
text
#### 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
}
}
text
#### 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

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
text

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);

text
#### 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

text

Usage Recommendations

#### Recommended Configuration (.NET 8.0 LTS)

As suggested by @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
text
#### 2. Enable Detailed Logging

Enable detailed logging in Senparc.Weixin configuration:

csharp
// appsettings.json
{
"SenparcWeixinSetting": {
"IsDebug": true,
// ...other settings
}
}
text
#### 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

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.
unitintegrationlivestress 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
.slnxpackages.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 IntegrationLiveStress
-
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
text
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

text

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"]);
});
text
#### ⚠️ 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

text

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)

Performance Optimization Summary - WeiXinMPSDK

问题描述 / Problem Description

您报告的问题:应用程序在使用 WeiXinMPSDK 时出现偶发的 API 响应超时(>5秒),通过 Nginx 日志确认确实存在响应缓慢的情况。

Your reported issue: The application experiences intermittent API response timeouts (>5 seconds) when using WeiXinMPSDK, confirmed by Nginx logs showing slow responses.

根本原因分析 / Root Cause Analysis

经过深入分析,我们发现了两个关键的性能瓶颈:

After deep analysis, we identified two critical performance bottlenecks:

1. 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()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"]);
text
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);
}
});
}

text
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");
...

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"]);
});
text

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);
text

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";
});
text

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
text
