在Server端解析HTTP請求的時候，

func ProcScaleOutReq(rsp http.ResponseWriter, req *http.Request) {
   req.ParseForm()

   //bodyStr := [1024]byte{}
   //bodySlc := bodyStr[:]
var bodySlc []byte = make([]byte, 1024)

   bodyLen,readErr := req.Body.Read(bodySlc)
   if readErr == nil {
      fmt.Println("read body error"
 
)
   }else{
      fmt.Println("the body has ",bodyLen," bytes")
   }

   fmt.Println("the body is:", string(bodySlc))
   fmt.Println("the len of body ", len(bodySlc))
   fmt.Fprintln(rsp, "hello" + req.URL.String())
   //var str := string(bodySlc) 這裡直接使用Read方法讀出來的byte[]，str中會有多餘的空格。str := byteString(bodySlc)
   fmt.Println
 
("the length of str is ",  len(str))
   var body2 ReqBody
   err := json.Unmarshal([]byte(str), &body2)
   if err != nil {
      fmt.Println(err.Error())
   } else {
      fmt.Println("name:" + body2.Name)
      fmt.Println("name:" + body2.Body)
      fmt.Println("name:" + body2.Time)
   }

}
