標籤：amr   form   method   ade   stat   str   發送   enc   參數   

1.參數 paramsValue的格式 要和 Reques.ContentType一致，

如果 contentype  "application/x-www-form-urlencoded" 表單類型，那麼  參數為   a=1&b=2 形式

如果 。。。         "application/json"  json 類型  那麼參數就為  "{a:1,b:2}" 格式

 

2.可以添加自訂header,  add（key,value）

接受擷取header   Request.Headers.Get(key)
