最近在調試Http POST協議的接口時，對 TestHttpPost 進行了改進，增加了增加輸出文件、設置請求頭的功能。故發布了發布v1.2版。
一、變更說明
v1.2的變更說明——
- 框架版本改為
.NET Framework 4.5. 因為 WIndows 7、Windows Server 2008等操作系統自帶了.NET Framework 4.5或更高版本, 節省了安裝.NET 運行時的工作. - 增加輸出文件的功能. 增加了“OutputFile”的復選框及文本框.
- 增加設置請求頭的功能. 增加了“Header”選項卡, 其中可以設置請求頭。每一行的格式為“key: value”.
是在 hezlog 的改進版的基礎上改造的。感謝 hezlog 的貢獻.
二、使用介紹
默認是“POST”模式。在最上面的文本框中輸入Url地址，然后在“Post Data”文本框中輸入Post參數，再點擊“Go”按鈕發送請求。
如果想使用“GET”模式。便點擊左上角的組合框，選擇“GET”模式，再點擊“Go”按鈕發送請求。
下面介紹了更多用法。
- 當發現回應內容亂碼時。點擊“Response Encoding”組合框，選擇合適的編碼。再點擊“Go”按鈕發送請求。
- 當需要查看詳細日志時。勾選“log header”復選框。再點擊“Go”按鈕發送請求。
- 當需要輸出文件時。勾選“Output file”復選框，隨后在旁邊的文本框里輸入“輸出文件名”。再點擊“Go”按鈕發送請求。
- 當需要設置請求頭時。點擊“Header”切換到該選項卡，隨后在其中的文本框里輸入請求頭的內容，例如“Cookie: abc”。再點擊“Go”按鈕發送請求。
三、全部代碼
