Question

我使用GoLang代码进行HTTP GET调用：

client := &http.Client{}
req, _ := http.NewRequest("GET", getUrl, nil)
//req.Header.Set("Accept-Encoding", "br")
response, _ := client.Do(req)

收到错误回复：

<html>
     <head><title>400 Bad Request</title></head>
     <body bgcolor="white">
          <center><h1>400 Bad Request</h1></center>
          <hr><center>nginx</center>
     </body>
</html>

要打印上面的错误响应，我使用简单：

data, _ := ioutil.ReadAll(response.Body)
log.Println(string(data))

当我拿起getUrl并在Chrome浏览器中执行时，它会返回成功响应：

{"message":"SUCCESS","errorcode": "0" ,"errormessage":""}

Chrome请求标头：

    Accept-Encoding:gzip, deflate, br

Chrome回复标题：

请帮忙。

道歉，我找到了答案。之前我通过将所有参数附加到它来创建大型getUrl。完成下面的操作后，问题就解决了。

q := req.URL.Query()
q.Add("key", "value")
req.URL.RawQuery = q.Encode()
