从Restful API获取POST类型方法的响应

Question

How can I fetch the json response from the POST method? Currently I'm only able to fetch Status - 401 Unauthorized and StatusCode - 401

func postUrl(url string, byt []byte) (*http.Response, error) {
    tr := &http.Transport{
        DisableCompression: true,
    }
    client := &http.Client{Transport: tr, Timeout: 10 * time.Second}
    req, err := http.NewRequest("POST", url, bytes.NewBuffer(byt))
    req.Header.Set("X-Custom-Header", "myvalue")
    req.Header.Set("Content-Type", "application/json")
    req.Header.Add("Authorization", "Basic "+basicAuth("username", "password"))
    resp, err := client.Do(req)
    return resp, err
  }

Above code produces the output:

{
  "errorMessages": [
    "You do not have the permission to see the specified issue.",
    "Login Required"
  ],
    "errors": {}
}

The way to read the response (if there is one) is the same regardless of what status you get.

defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
