从 HTTP 标头复制 Post 操作

Question

我正在尝试向网站发送远程发布操作，以在特定时间间隔自动从一种状态更改为另一种状态，但是，我无法破译 HTTP 标头信息以获得所需的结果。每次我发一个帖子网站都不接受，所以很明显我的帖子解析不正确。

我捕获的工作HTTP Header信息如下：

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

POST /p/9998812/update_availability HTTP/1.1

有人可以为我提供的任何帮助都会很棒。我真的只是想了解如何将相同的参数传递给站点，以便我可以复制该功能。

谢谢

您需要发送请求行、标题、空白行，然后是数据（在 POST 请求的情况下）。对于上面的示例，它应该如下所示：

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

你没有说你用什么来向服务器发出请求。有几个非常强大的工具（例如用于 Unix/Linux 系统的curl）和许多非常强大且友好的库（例如用于 Python 的 requests），您可以使用它们来发出 HTTP 请求。这些为您处理协议细节的大量工作。

如果您正在编写自己的 HTTP 客户端，使用较低级别的网络库，您应该认真考虑使用这些工具之一。如果您有充分的理由不这样做，您应该查看指定 HTTP 的 RFC：http://www.w3.org/Protocols/rfc2616/rfc2616.html 或有关 HTTP 的综合资源。
