Http POST leads to : Too many arguments to return

I'm having some troubles trying to execute a POST using Golang. With the code below

func Postfunc(w http.ResponseWriter , rep *http.Request) {
     var jsonStr = []byte(`{"id":"10012"}`)
     req, err := http.NewRequest("POST", "url", bytes.NewBuffer(jsonStr))
     req.Header.Set("Content-Type", "application/Text")
     client := &http.Client{}
     resp, err := client.Do(req)
     if err != nil {
         panic(err)
     }
     fmt.Println("responce Status:", resp.Status)
     fmt.Println("responce Headers:", resp.Header)
     defer resp.Body.Close()
     bodyText, err := ioutil.ReadAll(resp.Body)
     fmt.Println("responce Body:", string(bodyText))
     p := string(bodyText)
     return  p
}

I get the following error:

too many arguments to return, have (string), want ()

What does this error mean? How can I fix this?

The error is exactly right. Your function signature is:

func Postfunc(w http.ResponseWriter , rep *http.Request)

It has no return values. Therefore, your last line:

return  p

Has too many arguments, which would be any arguments at all. If you want to write text to the HTTP response, use the ResponseWriter:

w.Write(bodyText)
