cookicontainer不会保存所有的cookie

我正在使用WebClient登录Wordpress博客,我的WebClient方法:
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request.GetType() == typeof(HttpWebRequest))
{
((HttpWebRequest)request).CookieContainer = cookieContainer;
foreach (Cookie c in cookieContainer.GetCookies(address))
{
Console.WriteLine(" cName: " + c.Name);
Console.WriteLine(" cValue: " + c.Value);
Console.WriteLine(" cPath: " + c.Path);
Console.WriteLine(" cDomain: " + c.Domain);
}
((HttpWebRequest)request).UserAgent = userAgent;
((HttpWebRequest)request).Timeout = timeout;
((HttpWebRequest)request).Accept = accept;
}
return request;
}
[DebuggerNonUserCode()]
protected override WebResponse GetWebResponse(WebRequest request)
{
try
{
WebResponse response = base.GetWebResponse(request);
if (response.GetType() == typeof(HttpWebResponse))
{
foreach (Cookie c in ((HttpWebResponse)response).Cookies)
{
Console.WriteLine(" Name: " + c.Name);
Console.WriteLine(" Value: " + c.Value);
Console.WriteLine(" Path: " + c.Path);
Console.WriteLine(" Domain: " + c.Domain);
}
characterSet = ((HttpWebResponse)response).CharacterSet;
}
return response;
}
catch (System.Net.WebException e)
{
throw e;
}
}
现在当我尝试登录wordpress发送四个cookie和302重定向
Set-Cookie: wordpress_a235c74829f55a618a01c9f088805f08=precmast%7C1318622660%7C45c78363a5062b592b1fe49201fea5a8; path=/wp-content/plugins; httponly
Set-Cookie: wordpress_test_cookie=WP+Cookie+check; path=/
Set-Cookie: wordpress_a235c74829f55a618a01c9f088805f08=precmast%7C1318622660%7C45c78363a5062b592b1fe49201fea5a8; path=/wp-admin; httponly
Set-Cookie: wordpress_logged_in_a235c74829f55a618a01c9f088805f08=precmast%7C1318622558%7Ca28c4bf14832cbbee606cdddcad9e019; path=/; httponly
但是WebResponse只包含2个cookie (path=/),当它自动重定向时,它不会发送另外2个cookie,所以我无法登录。现在我通过手动处理响应中的重定向和cookie解决了这个问题。报头["Set-Cookie"]和响应。标题("位置")。但我想知道有没有其他的解决办法?
实际解决 if (response.GetType() == typeof(HttpWebResponse))
{
if(response.Headers["Location"] != null)
{
cookieContainer.Add(response.ResponseUri, GetAllCookiesFromHeader(response.Headers["Set-Cookie"], response.ResponseUri.Host));
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(response.Headers["Location"]);
req.Method = "GET";
req.AllowAutoRedirect = false;
req.CookieContainer = cookieContainer;
req.UserAgent = userAgent;
req.Timeout = timeout;
req.Accept = accept;
return GetWebResponse(req);
}
试试这个:
request.AllowAutoRedirect = false;
你要做的是:
- 找出当你登录时发送到wordpress网站的"Post"。
- firefox的'Live HTTP Headers'插件是一个检查报头的好插件。
- 查看Post信息 然后使用HttpWebRequest重新创建发送该信息。
- 在请求中添加一个真实的UserAgent字符串是个好主意,这样你看起来就像一个真实的人
- 不那么重要,但是在请求上有一个逻辑引用者也不是一个坏主意
- 将CookieContainer附加到请求以获取登录cookie。
- 为了避免在每次启动程序时都这样做:
- 可以序列化和反序列化CookieContainer 对于序列化,我个人成功地使用了BinaryFormatter
我不确定提供代码示例是否具有建设性。有了这些信息,找出如何自己编写代码比仅仅复制和粘贴更有意义。但是,如果你想要任何代码示例,请留下评论
