其实就是用hyper请求https://httpbin.org，服务端验证了证书，而客户端没有使用证书。所以报错,报错如下:

现在就是判断出现证书问题的时候，做一个任务。现在无法判断这个Error是证书出错了。hyper包装了好几层，里面还有部分是c++的error。
评论区
写评论刚把这个问题解决了，自己回复一下，用的是hyper+openssl这个crate来发送https的请求。
let res = client.request(request).await.map_err(|e| { let message = e.to_string(); if let Some(e1) = e.into_cause() { if let Some(e2) = e1.source() { let tt = e2.downcast_ref::ssl::Error(); if let Some(ssl_error) = tt { if ssl_error.code() == ssl::ErrorCode::SYSCALL { return anyhow!("Please use a valid ssl certificate or add the flag '-k' to skip the certificate validation."); } } } } return anyhow!("{}", message); })?;
