Golang：解释 DumpRequest 和 DumpResponse HTTP/2
Golang: Explain DumpRequest and DumpResponse HTTP/2
clientt := &http.Client{
Timeout: 30 * time.Second,
}
var tr = &http2.Transport{}
clientt.Transport = tr
我创建了一个客户端并发送了 http/2 请求。使用 http2 传输
但在 DumpRequest 中我看到
获取/HTTP/1.1
主持人：www.xxxxq23.com
在响应转储中我看到 HTTP/2.0
为什么要求使用 HTTP/1.1？
如何改成HTTP/2.0
HTTP/2 是二进制的，而不是文本的，转储为二进制将是不可读和无用的。这是有意设计的，很好 documented:
DumpRequest returns the given request in its HTTP/1.x wire
representation. It should only be used by servers to debug client
requests. The returned representation is an approximation only; some
details of the initial request are lost while parsing it into an
http.Request. In particular, the order and case of header field names
are lost. The order of values in multi-valued headers is kept intact.
HTTP/2 requests are dumped in HTTP/1.x form, not in their original
binary representations.
If body is true, DumpRequest also returns the body. To do so, it
consumes req.Body and then replaces it with a new io.ReadCloser that
yields the same bytes. If DumpRequest returns an error, the state of
req is undefined.
