如何在同一页面保持session

发布于 2024-09-13 20:44:44 字数 354 浏览 10 评论 0原文

在我的页面加载中，我得到了会话[“name”]

当我使用此代码保存时：

Stream stream = null;
request = (HttpWebRequest)WebRequest.Create(url);
response = (HttpWebResponse)request.GetResponse();

当涉及到这一行时：

response = (HttpWebResponse)request.GetResponse();

它再次移至页面加载，此时会话为空。如何？？？如何在同一页面保持会话。为什么当这一行遇到...时它被清除

会话不通过 HttpWebResponse 持续存在的原因是，默认情况下，HttpWebResponse 不会为您处理 cookie。 ASP.NET 使用 cookie 来识别哪个会话属于用户。

值得庆幸的是，有一个名为 CookieContainer 的帮助器类可以帮助您完成此任务。创建一个 CookieContainer 并将其附加到您的 Web 请求 - 在后续请求中，您将需要将 Cookie 容器或其中的 Cookie 再次附加到请求以保留会话：

CookieContainer cookieJar = new CookieContainer();
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.google.com");
request.CookieContainer = cookieJar;

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

// on a second request, you can use the cookieJar container to pass the session cookie.

The reason that sessions don't persist with HttpWebResponse is because by default, HttpWebResponse will not handle cookies for you. ASP.NET uses a cookie to identify which session belongs to a user.

Thankfully, there's a helper class called CookieContainer that can help you with this. Create a CookieContainer and attach it to your web request - on subsequent requests, you will need to attach the cookie container, or the cookies within it to the request again to persist session:

CookieContainer cookieJar = new CookieContainer();
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.google.com");
request.CookieContainer = cookieJar;

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

// on a second request, you can use the cookieJar container to pass the session cookie.
