Session怎么获得？

sandy1231 · 发表于 2013-12-19 20:47:45

C# post登陆dede每次得到的Session都是不一样的，而用抓包工具每次返回的Session都是一样的，就算登陆成功也不会改变，只有清空了SESSION才会改变。
比如说没有成功登陆前获得Session是233ec8502edaa126e0a64e73b46760da，放在C#的程序里面提示没有登陆，而抓包工具成功登陆后，C#才会显示登陆成功
请问这是什么原理？怎么获得正确的Session呢？谢谢

你提供下登录的包信息，要成功登录的。
有可能是你没有登录成功造成的，C#的Http是不会保持的，你获取Session的只是一个ID，你需要带着这本次请求成功获取到的Cookie才要吧继续访问，你每请求一次变化一个Session这是正常的。因为他不会保持

已经登陆成功就是发布文章不行，返回的数据好奇怪，也没提示失败。@站长苏飞飞哥有空帮我看看可以吗，谢谢。
C#代码：

[C#] 纯文本查看 复制代码

 HttpHelper tool = new HttpHelper();
HttpItem item = new HttpItem();
HttpResult result = new HttpResult();
item.Method = "POST";
item.URL = "http://localhost/dede/dede/article_add.php";
item.Postdata = "typeid=1&channelid=1&title=sssssssss&body=dddddddddd";
item.Cookie = MainCookie.Cookie;
result = tool.GetHtml(item);
richTextBoxEx1.AppendText("\n" + result.Html);

Httphelper返回的html是一个添加文章的页面，不知为什么会返回这样的数据，也没提示失败之类的。
