异步请求多个响应golang

Question

I need to make a request to a server that return different responses at different times. I mean, the server generate different responses and these responses take different execution time, so server return the responses as soon as they are available.

And I want print in the screen (by the moment, I'd settle with that) these responses as soon as the server returns me.

All what I could do until now is print the responses but only when the server returns all the responses. So if the first response take 1sec, and the last response take 10sec, my code needs to wait 10sec to print all the messages.

EDIT: to add code I have:

//Config is gotten from yml file
RestConfig       = Config["rest"].(map[string]interface{})
ServerConfig     = Config["server"].(map[string]interface{})
RequestUrl      := ServerConfig["url"]

RequestReader   := bytes.NewReader(body)
Request, _      := http.NewRequest("POST", RequestUrl.(string), RequestReader)

//AppendHeaders append the needing headers to the request 
client.AppendHeaders(Request, RestConfig["headers"])

//the type of client.HttpClient is *http.Client
Response, _     := client.HttpClient.Do(Request)

//And to print in the screen
defer Response.Body.Close()

fmt.Println( "-> Receiving response:
---
" )
fmt.Println( Response , "
---
-> Response body:
---
")
body_resp, _ := ioutil.ReadAll(Response.Body)
fmt.Println( string(body_resp) )
fmt.Println( "
--
")

Any way to do it??

Thank you very much.

Finally my code , is like this:

package main

import (
    "fmt"
    "log"
    "bytes"
    "strings"
    "bufio"
    "net/http"
)

func main() {
  var body = "The body"
  RequestReader := bytes.NewReader([]byte(body))
  req, err := http.NewRequest("POST", "the_url", RequestReader)
  if err != nil {
    log.Fatal(err)
  }
  req.Header.Add("Accept", "application/xml")
  req.Header.Add("Content-Type", "application/xml")
  req.Header.Add("AG-Authorization", "key")
  req.Header.Add("AG-Forwarded-Hosts", "*")

  resp, err := (&http.Client{}).Do(req)
  if err != nil {
    log.Fatal(err)
  }
  reader := bufio.NewReader(resp.Body)
  message := ""
  for {
    line, err := reader.ReadBytes('
')
    if err != nil {
      log.Fatal(err)
 }
    message = message + string(line)
    if strings.Contains(message, "<!-- End mark for each message -->"){
        fmt.Println(message)
        message = ""
    }
  }
}

Thank everyone.
