问题

使用golang可以发送HTTP/1.0的请求吗？

我尝试了以下代码：

req, _ := http.NewRequest("POST", url, buffer)
req.Proto = "HTTP/1.0"
client := &http.Client{}
resp, err = client.Do(req)

但是似乎req.Proto被忽略了，请求仍然使用HTTP/1.1发送出去。

英文:

Is it possible to send HTTP requests using HTTP/1.0 with golang?

I tried the following:

req, _ := http.NewRequest(&quot;POST&quot;, url, buffer)
req.Proto = &quot;HTTP/1.0&quot;
client := &amp;http.Client{}
resp, err = client.Do(req)

But it seems req.Proto is ignored. The message is sent out using HTTP/1.1.

显然你不能这样做。当使用Client进行请求时，Request.Proto字段会被忽略。

引用自http.Request的文档：

// 传入请求的协议版本。
// 客户端请求始终使用HTTP/1.1。
Proto string // "HTTP/1.0"

客户端请求始终使用HTTP/1.1。

英文:

Apparently you can't. The Request.Proto field is ignored when making the request by the Client.

Quoting from the doc of http.Request:

// The protocol version for incoming requests.
// Client requests always use HTTP/1.1.
Proto      string // &quot;HTTP/1.0&quot;

> Client requests always use HTTP/1.1.
