使用HttpWebRequest发送Cookie [英] Send Cookies With HttpWebRequest

问题描述

我试图登录到我经常访问的网站中的Ajax聊天室。我希望创建各种审核机器人，但是我对Cookie的处理很感兴趣。我已经搜索了该网站上的所有问题，但是所有解决方案似乎都可以正确地执行我的操作，即设置的 CookieContainer 参数HttpWebRequest 到 cc 。 CookieContainer 填充了数据，但此数据未与 HttpWebRequest 发送。我的代码如下所示。

I am attempting to log in to an Ajax chatroom in a website I often visit. I desire to create a moderation bot of sorts, but I am hung up on cookie handling. I have searched through all of the questions on this website, but all solutions seem to do exactly what I am doing, which is setting the CookieContainer parameter of HttpWebRequest to cc. The CookieContainer gets populated with data, but this data does not get sent with the HttpWebRequest. My code is shown below.

    class Program
{
    static config populated_config;
    static void Main(string[] args)
    {
        #region config
        StreamReader sr = new StreamReader(File.Open("config.xml", FileMode.Open), Encoding.UTF8);
        XmlSerializer xmls = new XmlSerializer(typeof(config));
        populated_config = (config)xmls.Deserialize(sr);
        #endregion

        #region login

        //retrieve default cookies
        CookieContainer cc = new CookieContainer();

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(populated_config.domain + "chat/");
        request.CookieContainer = cc;
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        string login_info = "login=login&redirect=http%3A%2F%2F"+WebUtility.UrlEncode(populated_config.domain)+"%2Fchat%2F%3FchannelName%3DPublic&username=" + WebUtility.UrlEncode(populated_config.username) + "&password=" + WebUtility.UrlEncode(populated_config.password) + "&channelName=Public&lang=en&submit=Login";
        request = (HttpWebRequest)WebRequest.Create(populated_config.domain + "ucp.php?mode=login");
        request.CookieContainer = cc;
        request.Method = "POST";
        StreamWriter sw = new StreamWriter(request.GetRequestStream());
        sw.Write(login_info);
        response = (HttpWebResponse)request.GetResponse();

        string sid = findCookieValue(cc, "phpbb3_jznvi_sid");
        request = (HttpWebRequest)WebRequest.Create(populated_config.domain + "chat/?channelName=Public&sid=" + sid);
        request.CookieContainer = cc;
        request.Method = "GET";
        response = (HttpWebResponse)request.GetResponse();
        #endregion
    }

    public static string findCookieValue(CookieContainer cc,string cookieName)
    {
        foreach (Cookie cookie in cc.GetCookies(new Uri(populated_config.domain)))
            if (cookie.Name == cookieName)
                return cookie.Value;
        return null;
    }
}

使用 HttpWebRequest 而不自己亲自制作标题，我做错了什么？

What can be done to send the cookies with the HttpWebRequest without manually crafting the header myself, and what am I doing incorrectly?

推荐答案

在这里使用Justin和Rajeesh的答案：在WebClient类中使用CookieContainer 我发送了cookie手动像这样：

Using Justin and Rajeesh's answer here: Using CookieContainer with WebClient class I sent the cookies manually like this:

        string login_info = "login=login&redirect=http%3A%2F%2F"+WebUtility.UrlEncode(populated_config.domain)+"%2Fchat%2F%3FchannelName%3DPublic&username=" + WebUtility.UrlEncode(populated_config.username) + "&password=" + WebUtility.UrlEncode(populated_config.password) + "&channelName=Public&lang=en&submit=Login";
        request = (HttpWebRequest)WebRequest.Create(populated_config.domain + "ucp.php?mode=login");
        request.Method = "POST";
        //manually populate cookies
        Console.WriteLine(cc.GetCookieHeader(new Uri(populated_config.domain)));
        request.Headers.Add(HttpRequestHeader.Cookie,cc.GetCookieHeader(new Uri(populated_config.domain)));
        StreamWriter sw = new StreamWriter(request.GetRequestStream());
        sw.Write(login_info);
        response = (HttpWebResponse)request.GetResponse();
