1，发送http post请求（客户端）

func httppost()  {	data :=`{"type":"10","msg":"hello."}`	request, _ := http.NewRequest("POST", "http://0.0.0.0:8090/msg", strings.NewReader(data))	//post数据并接收http响应	resp,err :=http.DefaultClient.Do(request)	if err!=nil{		fmt.Printf("post data error:%v\n",err)	}else {		fmt.Println("post a data successful.")		respBody,_ :=ioutil.ReadAll(resp.Body)		fmt.Printf("response data:%v\n",string(respBody))	}}

　　2，接收方法（服务端）

package mainimport (	"net/http"	"io/ioutil"	"fmt")func main()  {	//设置路由和接收HTTP请求的方法	mux :=http.NewServeMux()	mux.HandleFunc("/msg",recvHandle)	//设置http服务	server :=&http.Server{		Addr:    "0.0.0.0:8090",		Handler: mux,	}	//启动监听	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.")}
