+ "/* 添加自定义日志记录\n",
+ " 1、可以指定当 HttpClient 启动请求、接收响应或引发异常时记录的内容和方式。可以同时添加多个自定义记录器(控制台、ETW 记录器)，或“包装”和“不包装”记录器。由于其附加性质，可能需要事先显式删除默认的“旧”日志记录。\n",
+ " 要添加自定义日志记录，您需要实现 IHttpClientLogger 接口，然后使用 AddLogger 将自定义记录器添加到客户端。请注意，日志记录实现不应引发任何异常，否则可能会中断请求执行\n",
+ " 2、请求上下文对象\n",
+ " 上下文对象可用于将 LogRequestStart 调用与相应的 LogRequestStop 调用相匹配，以将数据从一个调用传递到另一个调用。 Context 对象由 LogRequestStart 生成，然后传递回 LogRequestStop。这可以是属性包或保存必要数据的任何其他对象。\n",
+ " 如果不需要上下文对象，实现可以从 LogRequestStart 返回 null。\n",
+ " 3、避免从内容流中读取\n",
+ " 例如，如果您打算阅读和记录请求和响应内容，请注意，它可能会对最终用户体验产生不利的副作用并导致错误。例如，请求内容可能在发送之前被消耗，或者巨大的响应内容可能最终被缓冲在内存中。此外，在 .NET 7 之前，访问标头不是线程安全的，可能会导致错误和意外行为。\n",
+ " 4、谨慎使用异步日志记录\n",
+ " 我们期望同步 IHttpClientLogger 接口适用于绝大多数自定义日志记录用例。出于性能原因，建议不要在日志记录中使用异步。但是，如果严格要求日志记录中的异步访问，您可以实现异步版本 IHttpClientAsyncLogger。它派生自 IHttpClientLogger，因此可以使用相同的 AddLogger API 进行注册。\n",
+ " 请注意，在这种情况下，还应该实现日志记录方法的同步对应项，特别是如果该实现是面向 .NET Standard 或 .NET 5+ 的库的一部分。同步对应项是从同步 HttpClient.Send 方法调用的；即使 .NET Standard 表面不包含它们，.NET Standard 库也可以在 .NET 5+ 应用程序中使用，因此最终用户可以访问同步 HttpClient.Send 方法。\n",
+ " 5、包装和不包装记录仪：\n",
+ " 当您添加记录器时，您可以显式设置wrapHandlersPipeline参数来指定记录器是否将被包装。默认不包装。\n",
+ " 在将重试处理程序添加到管道的情况下（例如 Polly 或某些重试的自定义实现），包装和不包装管道之间的区别最为显着。\n",
