英文:
Go - http.Post method returns 400 Bad Request while http.Get seems to work
问题
使用以下代码：
// fpCode和fpParams是字符串
ingestionBody := strings.NewReader(fpCode+fpParams)
resp, err := http.Post("http://192.168.1.151:8080/ingest?", "text/plain", ingestionBody)
我得到了错误信息：
"HTTP/1.1 POST /ingest" - 400 Bad Request
我不知道我是否正确使用了Post方法（即使在这个答案中，他们似乎以类似的方式使用它。这是我能找到的唯一一个例子，不幸的是Go文档缺乏示例），问题可能出在第二个参数上，它应该是不同的东西（但我也尝试过"text/*"），或者我漏掉了一些重要的东西。
英文:
With the following code:
//fpCode and fpParams are strings
ingestionBody := strings.NewReader(fpCode+fpParams)
resp, err := http.Post("http://192.168.1.151:8080/ingest?", "text/plain", ingestionBody)
I'm getting the error message:
"HTTP/1.1 POST /ingest" - 400 Bad Request
I don't know if I'm not using the Post method right (even when in this answer, they seem to use it in a similar way. Is the only example that I was able to find, unfortunatelly Go documentation lacks of examples), the problem is with the second parameter, which should be something different (but I also tried "text/*") or there is something important that I'm missing.

如果你正在进行POST请求，你应该使用application/x-www-form-urlencoded或multipart/form-data作为content-type。
最终你需要查看服务器日志来确定请求失败的原因。
你可以尝试使用http.PostForm()代替。
英文:
If you're doing a POST you should probably be using a content-type of application/x-www-form-urlencoded or multipart/form-data.
Ultimately you need to look at the server logs to determine why the request is failing.
You might try <a href="http://golang.org/pkg/net/http/#Client.PostForm">http.PostForm()</a> instead.

也许你可以尝试使用http.PostForm：
form := url.Values{}
form.Add("field1", a)
form.Add("field2", b)
http.PostForm("http://192.168.1.151:8080/ingest", form)
英文:
Perhpas you can try http.PostForm:
form := url.Values{}
form.Add("field1", a)
form.Add("field2", b)
http.PostForm("http://192.168.1.151:8080/ingest", form)
