关于解析器中的body_limit设置提问

[Yinpinghua]

麻烦问下，当用chunked 传输，就可以检测body_limit的限制，而非chunked传输就不检测body_limit限制

[madmongo1]

我会检查。 听起来像个虫子。

I will check. It sounds like a bug.

[Yinpinghua]

嗯，谢谢您啊

[Yinpinghua]

麻烦，问下这个bug将会在v1.75版本上修复嘛？

[madmongo1]

I have written extra tests for basic_parser and I can find no problem with the operation of body_limit.

Would you be able to share a minimal, complete program with me that demonstrates the issue?

我已经为basic_parser编写了额外的测试，并且body_limit的操作没有问题。

您可以与我共享一个最小的完整程序来演示该问题吗？

[Yinpinghua]

这不对吧，我之前调试过源码，还是有这问题的

[Yinpinghua]

http::async_read_header 先调用这个函数，然后再调用http::async_read 这个函数

[madmongo1]

您可以与我共享一个最小的完整程序来演示该问题吗？

[Yinpinghua]

我这边是个代理服务

[madmongo1]

请让您的客户分享一个“最小可编译的可验证示例”来说明问题。

您可以通过以下方式将代码括在反引号中，以在此问题的注释中发布代码：

void test()
{
  do_something();
}

@Yinpinghua Is this still open?

[Yinpinghua]

yes

Could you please provide a minimal, reproducible code? I have no idea what the problem is, as the provided code doesn't reveal any issues.
