C# 在WebBrowser中使用WebRequestCookie

我想使用

WebRequest

登录站点，然后在

WebBrowser

中显示站点（已登录）

但是如何将

WebRequest

cookie“复制”到

WebBrowser

提前感谢,

使用cookie collection获取cookie，本月我编写了类似的内容，我可以与您分享一些示例代码：

    static string GetFromServer(string URL, ref CookieCollection oCookie)
    {
        //first rquest
        // Create a request for the URL. 
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL);
        request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)";
        request.AllowAutoRedirect = false;
        // If required by the server, set the credentials.
        //request.Credentials = CredentialCache.DefaultCredentials;
        request.CookieContainer = new CookieContainer();
        if (oCookie != null)
        {
            foreach (Cookie cook in oCookie)
            {
                request.CookieContainer.Add(cook);
            }
        }

        // Get the response.
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        foreach (Cookie cook in response.Cookies)
        {
            oCookie.Add(cook);
        }
        // Display the status.
        while (response.StatusCode == HttpStatusCode.Found)
        {
            response.Close();
            request = (HttpWebRequest)HttpWebRequest.Create(response.Headers["Location"]);
            request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)";
            request.AllowAutoRedirect = false;
            request.CookieContainer = new CookieContainer();
            if (oCookie != null)
            {
                foreach (Cookie cook in oCookie)
                {
                    request.CookieContainer.Add(cook);
                }
            }
            response = (HttpWebResponse)request.GetResponse();
            foreach (Cookie cook in response.Cookies)
            {
                oCookie.Add(cook);
            }
        }
        Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        // Get the stream containing content returned by the server.
        Stream dataStream = response.GetResponseStream();
        // Open the stream using a StreamReader for easy access.
        StreamReader reader = new StreamReader(dataStream);
        // Read the content.
        string responseFromServer = reader.ReadToEnd();
        // Display the content.
        Console.WriteLine(responseFromServer);
        // Clean up the streams and the response.
        reader.Close();
        response.Close();
        return responseFromServer;
    }

现在您得到了cookies，只需将其设置为webBrowser控件，即可导入此方法：

    [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
    public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);

当你得到饼干后，就叫这个：

    string cookie_string = string.Empty;
        foreach (Cookie cook in cookieCon)
        {
            cookie_string += cook.ToString() + ";";
            InternetSetCookie(url, cook.Name, cook.Value);
        }
        webBrowser1.Navigate(url, "", null, "Cookie: " + cookie_string + Environment.NewLine);

请注意，这只是我的测试代码，主要是从msdn复制的，因此它可能有缺陷，您可能需要更多的异常处理

我应该依赖wininet.dll吗？它适用于各种系统和东西？嗯，这是一个很好的问题，但很抱歉，我还不太确定，但这就是我发现如何才能真正做到的，WebBrowser控件似乎只是在使用IE，所以cookie应该与IE共享，如果你知道一些更好的方法，请务必让我知道，谢谢
