從HTTP標題複製Post操作

Question

我試圖發送遠程post操作到網站，以特定的時間間隔從一個狀態自動更改爲另一個狀態，但是，我無法解密HTTP標題信息以獲取所需的內容結果。每次我發佈帖子，網站都不接受，所以顯然我已經錯誤地解析了帖子。

我捕捉的工作HTTP頭信息如下：

http://URLXXX.com/p/9998812/update_availability 

POST /p/9998812/update_availability HTTP/1.1 
Host: URLXXX.com

任何幫助，有人能向我提供將是巨大的。我真的只是想了解如何將相同的參數傳遞給站點，以便我可以複製該函數。

感謝

您需要發送請求行，頭，一個空行，然後將數據（在POST請求的情況下）。對於上面的例子，這應該看起來像這樣：

POST /p/9998812/update_availability HTTP/1.1 
Host: URLXXX.com 
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101  Firefox/39.0 
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 
Accept-Language: en-US,en;q=0.5 
Accept-Encoding: gzip, deflate 
DNT: 1 
Referer: http://URLXXX.com/p/9998812/s/fwkA-irHT-2kMfS 
Cookie: 
Connection: keep-alive 
Content-Type: application/x-www-form-urlencoded 
Content-Length: 138 

utf8=%E2%9C%93&_method=put&authenticity_token=xMiaIdT%2Fnw%2FPbsYq%2BmVaLFnH362HIvIdXQQX3D%2F4uEo%3D&product%5Bstate%5D=active&commit=Save 

你沒有說你正在使用什麼來向服務器發送請求。有幾種功能非常強大的工具（比如用於Unix/Linux系統的curl）以及幾乎所有可用於製作HTTP請求的語言的很多非常強大和友好的庫（例如用於Python的requests）。這些爲你處理協議的細節做了很多工作。

如果你正在編寫自己的HTTP客戶端，使用低級網絡庫，你應該認真考慮使用這些工具之一。如果您有充分的理由不這樣做，您應該查看指定HTTP的RFC：http://www.w3.org/Protocols/rfc2616/rfc2616.html或HTTP上的綜合資源。
