c# - 使用 Httpwebrequest 登录网站

Question

我是编程 (C#) 的新手，我开始为 MMORPG 编写一个机器人来学习以编程方式与网站进行通信等等...

我在这里和那里发现了很多关于这个主题的问题。最后在帮助下，我可以找到一些东西并完成它，不幸的是它不起作用:(

方法:

    public static CookieCollection GetCookie(HttpWebRequest request)
    {

        if (request.CookieContainer == null)
        { return new CookieContainer().GetCookies(request.RequestUri); }
        else
        { return request.CookieContainer.GetCookies(request.RequestUri); }
    }


    public static CookieContainer GetCookie(HttpWebResponse response)
    {

        CookieContainer cookiecontainer = new CookieContainer();
        cookiecontainer.Add(response.Cookies);

        return cookiecontainer;
    }


    public static void SetCookie(HttpWebRequest request, CookieContainer cookie)
    {
        request.CookieContainer = cookie;
    }


    public static void SetCookie(HttpWebResponse response, CookieCollection cookie)
    {
        response.Cookies = cookie;
    }


    public static HttpWebResponse PostData(string uri,string request,CookieContainer cookie)
    {
        HttpWebRequest httprequest;
        byte[] requestbytes;
        Stream requeststream;
        HttpWebResponse httpresponse;

        httprequest = (HttpWebRequest)HttpWebRequest.Create(uri);

        if (cookie == null)
        {httprequest.CookieContainer=new CookieContainer();}
        else
        {httprequest.CookieContainer=cookie;}

        httprequest.Method = "POST";
        httprequest.ContentType = "application/x-www-form-urlencoded";
        httprequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.142 Safari/535.19";
        requestbytes = ASCIIEncoding.ASCII.GetBytes(request);
        httprequest.ContentLength = requestbytes.Length;

        requeststream=httprequest.GetRequestStream();
        requeststream.Write(requestbytes,0,requestbytes.Length);
        requeststream.Close();

        httpresponse=(HttpWebResponse)httprequest.GetResponse();

        if (!(httpresponse.Cookies.Count>0))
        { SetCookie(httpresponse, GetCookie(httprequest)); }

        return httpresponse;
    }


    public static HttpWebResponse GetData(string uri, CookieContainer cookie)
    {
        HttpWebRequest httprequest;
        HttpWebResponse httpresponse;

        httprequest = (HttpWebRequest)HttpWebRequest.Create(uri);

        if (cookie == null)
        { httprequest.CookieContainer = new CookieContainer(); }
        else
        { httprequest.CookieContainer = cookie; }

        httprequest.Method = "GET";
        httprequest.ContentType = "application/x-www-form-urlencoded";
        httprequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.142 Safari/535.19";

        httpresponse = (HttpWebResponse)httprequest.GetResponse();

        if (!(httpresponse.Cookies.Count > 0))
        { SetCookie(httpresponse, GetCookie(httprequest)); }

        return httpresponse;
    }

主要内容:

        string uri = "http://s2.kingsera.org";
        string userName = "someUserName";
        string passWord = "somePassWord";

        string postData = "signinUsername=" + userName + "&signinPassword=" + passWord + "&signinRemember=remember";
        CookieContainer cookie = new CookieContainer();

        HttpWebResponse response = PostData(uri, postData, cookie);

        CookieContainer c = GetCookie(response);

看来登录页面正在做一些事情，让它变得更复杂了! http://s2.kingsera.org

我不会从技术上回答你的问题，但当我遇到这样的事情时，我会转向 Fiddler ，拦截您的计算机和远程服务器之间的网络流量。

这将允许您查看您的浏览器向远程服务器发出的确切请求及其所有 header 、cookie 数据等，以及您的代码向远程服务器发出的请求。

两个请求之间的差异应该向您展示解决问题的方法，或者至少为您提供大量额外信息以进行故障排除。
