Question

发送从httpwebrequest收到的cookie没有给出正确的结果，但是如果我从浏览器cookie复制粘贴cookie值而不是返回正确的结果。为什么我没有从httpwebrequest获得结果但是在浏览器中工作得很好？

CookieContainer cookieContainer = new CookieContainer();

var targetUri = new Uri("URL1");
HttpWebRequest myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(targetUri);
myHttpWebRequest.Method = "GET";
myHttpWebRequest.CookieContainer = cookieContainer;

//Get Response
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

//Create Request
targetUri = new Uri("URL2");
myHttpWebRequest = (HttpWebRequest)HttpWebRequest.Create(targetUri);
myHttpWebRequest.Method = "GET";
myHttpWebRequest.CookieContainer = cookieContainer;

//Get Response
myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

using (StreamReader reader = new StreamReader(myHttpWebResponse.GetResponseStream()))
{
   string html = reader.ReadToEnd();
}

以下是通过第一次请求（URL1）收到cookie的第二个请求（URL2）fiddler：

Request:
GET URL2 
HTTP/1.1
Host: www.xyz.com
Cookie: JSESSIONID=Mn7qJwrRnxLn1NNfT1PNr1L2Gr2KCkfFVCRS1wfsT4zfzWJhT62J!-876337174

Response:
HTTP/1.1 200 OK
Date: Fri, 27 Feb 2015 13:03:52 GMT
Content-Length: 13
Content-Type: text/html;charset=UTF-8
X-Powered-By: Servlet/2.5 JSP/2.1

现在，如果我在浏览器中复制粘贴第一个URL（URL1）并使用浏览器中的cookie值，那么它将返回正确的结果：

Request:

GET URL2 
HTTP/1.1
Host: www.xyz.com
Cookie: JSESSIONID=PPPHJwmKQNh2ykVXytlcfTDH2YWNbtv76vPBzZTG3Dfdm9Mx0J74!-876337174

Response:
HTTP/1.1 200 OK
Date: Fri, 27 Feb 2015 13:06:15 GMT
Content-Type: text/html;charset=UTF-8
X-Powered-By: Servlet/2.5 JSP/2.1

Answer 1

Weblogic在响应中返回cookie，您需要在下一个请求中将其发回。

cookieContainer.Add(response.Cookies);

（您的cookieContainer在您的计算机上并且为空）。
