c#使用WebBrowser cookie的WebRequest

Question

我使用WebBrowser登录网站,然后我想使用正则表达式获取一些数据,但webRequest没有使用web Browse cookie,

我的webBrowser是公开的,有没有办法在webRequest中使用WebBrowser cookie？

Answer 1

    public CookieContainer GetCookieContainer()
    {
        CookieContainer container = new CookieContainer();

        foreach (string cookie in webBrowser1.Document.Cookie.Split(';'))
        {
            string name = cookie.Split('=')[0];
            string value = cookie.Substring(name.Length + 1);
            string path = "/";
            string domain = ".google.com"; //change to your domain name
            container.Add(new Cookie(name.Trim(), value.Trim(), path, domain));
        }

        return container;
    }

这适用于大多数网站,但使用子域的网站可能存在问题.

Answer 2

您可以将CookieContainer用于Webrequest.

 web_cookies = new CookieContainer();
 // Create a 'WebRequest' object with the specified url.                 
 HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(url);

 myWebRequest.CookieContainer = web_cookies;

希望这可以帮助.

好的,你想登录.这就是不同的故事.您可以使用NetworkCredential.

public string get_secure_webpage(string url, string username, string password)
    {
        WebRequest myWebRequest = WebRequest.Create(url);
        NetworkCredential networkCredential = new NetworkCredential(username, password);
        myWebRequest.Credentials = networkCredential;
