如何在Golang中发送POST请求？

问题描述

我发现go http包非常混乱。我认为客户端和服务器应该分成两个不同的包，也许是第三个包含常见的东西。

I find the go http package quite confusing. I think the client and server should be separated in two different package and perhaps a 3rd with the common stuff.

无论如何尝试创建POST请求，但我无法获得它完成了。没有收到另一方。
这是应该如何工作的？我知道功能，但我认为我不能使用它，因为它可以'您可以使用进行测试吗？

Anyway trying to make a POST request but I can't get it done. Nothing is received on the other side. Is this how it is supposed to work ? I'm aware of the PostForm function but I think I can't use it because it can't be tested with httputil right ?

hc := http.Client{}
    req, err := http.NewRequest("POST", APIURL, nil)

    form := url.Values{}
    form.Add("ln", c.ln)
    form.Add("ip", c.ip)
    form.Add("ua", c.ua)
    req.PostForm = form
    req.Header.Add("Content-Type", "application/x-www-form-urlencoded")

    glog.Info("form was %v", form)
    resp, err := hc.Do(req)

推荐答案

你大多是正确的想法，它只是发送错误的表单。

You have mostly the right idea, it's just the sending of the form that is wrong. The form belongs in the body of the request.

req, err := http.NewRequest("POST", url, strings.NewReader(form.Encode()))
