Println ("Post a data successful.") Respbody,_: =ioutil. ReadAll (resp. Body) fmt. Printf ("Response data:%v\n", String (Respbody))}}

Package Mainimport ("Net/http" "Io/ioutil" "FMT") func main ()  {//Set the route and receive HTTP requests by MUX: =http. Newservemux () Mux. Handlefunc ("/msg", Recvhandle)//Set HTTP service server: =&http. SERVER{ADDR:    "0.0.0.0:8090", handler:mux,}//start monitoring Server. Listenandserve ()}func recvhandle (w http. Responsewriter, R *http. Request)  {body,_: =ioutil. ReadAll (r.body) fmt. Println (String (body)) fmt. fprintf (W, "3q your Msg.")}
