I have two go programs - one running as a server daemon, the other being executed manually. I want to be able to send a request to the server from the other program, sending some binary data there via post request. How can I do this?
I know I can send a string like this:
data := url.Values{}
data.Set("req", buf)
u, _ := url.ParseRequestURI(domain)
u.Path = path
urlStr := fmt.Sprintf("%v", u)
client := &http.Client{}
r, _ := http.NewRequest("POST", urlStr, bytes.NewBufferString(data.Encode()))
r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))
resp, _ := client.Do(r)
return resp.Status
But I want to send an octet-stream
which I can then read from ioutil.ReadAll(r.Body)
.
