GoLang HTTP GET - 400 Bad Request

Question

I am making HTTP GET call using below GoLang code:

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

Receiving error response:

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

To print above error response, I am using simple:

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

When I pick up getUrl and execute simply in Chrome browser, it returns success response:

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

Chrome request header:

    Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8
    Accept-Encoding:gzip, deflate, br
    Accept-Language:en-GB,en-US;q=0.9,en;q=0.8

Chrome response headers:

Access-Control-Allow-Headers:accept, content-type

Please help.

Thanks Himanshu, added in post -> data, _ := ioutil.ReadAll(response.Body) — Nikhil Joshi, Feb 18 '18 at 11:25
you should be more specific in your post. Your code is simple. And It is hard to analyze here what is going wrong. Nothing seems wrong in your posted code — Himanshu, Feb 18 '18 at 11:57
Sorry Himanshu, problem is now resolved, I have posted self answer. — Nikhil Joshi, Feb 18 '18 at 12:00

Apologies, I found the answer. Earlier I use to create big getUrl by appending all parameters to it. After doing below, the problem was resolved.

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