在WebBrowser中使用CookieContainer中的cookie

有没有办法可以实际使用cookie容器中的cookie（以前从WebRequest中获取）并在WebBrowser控件中使用它们？ 如果是这样，我该怎么做？ 这适用于C＃中的Winforms应用程序。

Answer 1

您需要使用InternetSetCookie 。 这是一个样本 ……

public partial class WebBrowserControl : Form { private String url; [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData); public WebBrowserControl(String path) { this.url = path; InitializeComponent(); // set cookie InternetSetCookie(url, "JSESSIONID", Globals.ThisDocument.sessionID); // navigate webBrowser.Navigate(url); } } 

Answer 2

这是一个例子哦如何实现这一目标：

 private class CookieAwareWebClient : WebClient { public CookieAwareWebClient() { CookieContainer = new CookieContainer(); } public CookieContainer CookieContainer { get; private set; } protected override WebRequest GetWebRequest(Uri address) { var request = base.GetWebRequest(address); var httpRequest = request as HttpWebRequest; if (httpRequest != null) { httpRequest.CookieContainer = CookieContainer; } return request; } } private void Form1_Load(object sender, EventArgs e) { using (var client = new CookieAwareWebClient()) { client.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials; client.DownloadData("http://www.google.com"); var cookies = client.CookieContainer.GetCookies(new Uri("http://www.google.com")); var prefCookie = cookies["PREF"]; webBrowser1.Navigate("http://www.google.com", "", null, "Cookie: " + prefCookie.Value + Environment.NewLine); } } 

Answer 3

尝试首先使用“客户端”CookedWebClient进行第一次导航，并从服务器获取所有cookie。 然后，您可以从CookedWebClient或WebRequest等其他来源获取CookedContainer，并在WebBrowser中使用它们，如下所示：

 namespace ExampleWebBrowser { public partial class Form1 : Form { [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData); CookedWebClient client = new CookedWebClient(); .. .. .. private void usingWebBrowserWithWebClientCookies(string url) { CookieCollection cookies = client.Cookies.GetCookies(url); for (int i = 0; i < cookies.Count; i++) { Cookie c = cookies[i]; InternetSetCookie(url, c.Name, c.Value); } webBrowser1.Navigate(url); } } public class CookedWebClient : WebClient { CookieContainer cookies = new CookieContainer(); public CookieContainer Cookies { get { return cookies; } } protected override WebRequest GetWebRequest(Uri address) { WebRequest request = base.GetWebRequest(address); if (request.GetType() == typeof(HttpWebRequest)) ((HttpWebRequest)request).CookieContainer = cookies; return request; } } }
