关于获取cookie方法的实验（以抖音pc端为例）

bjszz

我将利用三种方法来实验获取cookie，分别是HttpWebRequest，HttpWebResponse，提交请求的方式获取。CefSharp方式和Selenium方式 获取代码在下方，一、HttpWebRequest，HttpWebResponse，提交请求的方式获取，手机扫码登录pc端获取cookie.
1、获取二维码链接：

public static string GetUrl(string Url)        {            string html = "";            string charset = "utf-8";            try            {                System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);  //创建一个链接                request.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)";                request.Referer = Url;                request.Proxy = null;                request.Headers.Add("Accept-Encoding", "gzip");                request.KeepAlive = true;                request.Accept = "*/*";                HttpWebResponse response = request.GetResponse() as HttpWebResponse;  //获取反馈                if (response.Headers["Content-Encoding"] == "gzip")                {                    GZipStream gzip = new GZipStream(response.GetResponseStream(), CompressionMode.Decompress);//解压缩                    StreamReader reader = new StreamReader(gzip, Encoding.GetEncoding(charset));                    html = reader.ReadToEnd();                    reader.Close();                }                else                {                    StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(charset));                    html = reader.ReadToEnd();                    reader.Close();                }                  response.Close();                return html;                  }            catch (System.Exception ex)            {                return ex.ToString();              }              }

3、请求返回Base64转图片方法：

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17

public Image Base64ToImage(string strbase64)         {             try             {                 byte[] arr = Convert.FromBase64String(strbase64);                 MemoryStream ms = new MemoryStream(arr);                 System.Drawing.Image mImage = System.Drawing.Image.FromStream(ms);                 ms.Close();                 return mImage;               }             catch (Exception ex)             {                 MessageBox.Show(ex.ToString());                 return null;             }         }

4、获取二维码成功后，可用手机扫码，建立时间事件来监听扫码行为，处理扫码成功后方法：

public void getSetCookie()         {             string Url = "https://sso.douyin.com/check_qrconnect/?aid=6383&app_name=douyin_web&device_platform=web&referer=&user_agent=Mozilla%2F5.0+(Windows+NT+6.3%3B+WOW64)+AppleWebKit%2F537.36+(KHTML,+like+Gecko)+Chrome%2F55.0.2883.87+UBrowser%2F6.2.4098.3+Safari%2F537.36&cookie_enabled=true&screen_width=1600&screen_height=900&browser_language=zh-CN&browser_platform=Win32&browser_name=Mozilla&browser_version=5.0+(Windows+NT+6.3%3B+WOW64)+AppleWebKit%2F537.36+(KHTML,+like+Gecko)+Chrome%2F55.0.2883.87+UBrowser%2F6.2.4098.3+Safari%2F537.36&browser_online=true&timezone_name=Asia%2FShanghai&next=https:%2F%2Fcreator.douyin.com%2F&token=" + token + "&service=https:%2F%2Fwww.douyin.com%2F&correct_service=https:%2F%2Fwww.douyin.com%2F&is_vcd=1&fp=kesopiod_fB4eRss7_Stsz_434j_AiPQ_6xhtUsqmqpSN";             System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;             HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);  //创建一个链接             request.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)";             request.Referer = Url;               HttpWebResponse response = request.GetResponse() as HttpWebResponse;  //获取反馈             StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"));             string html = reader.ReadToEnd();             string status = Regex.Match(html, @"""status"":""([\s\S]*?)""").Groups[1].Value;             string redirect_url = Regex.Match(html, @"""redirect_url"":""([\s\S]*?)""").Groups[1].Value;             if (status == "1")             {                 label1.Text = "未扫码..";             }             else if (status == "2")             {                 label1.Text = "已扫码..";             }             else if (redirect_url != "")             {                 timer1.Stop();                 label1.Text = "登录成功";                 string content = response.GetResponseHeader("Set-Cookie");                 Uri uri = new Uri("http://douyin.com");                 string cookies = CookieHelper.GetCookies(content, uri);                 string cookies2 = getSetCookie2(cookies);                 textBox1.Text = cookies2 + cookies;                 //insertcookie(cookies2 + cookies);               }             reader.Close();             }

5、处理扫码成功后方法2：

[C#] 纯文本查看 复制代码

?

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

public string getSetCookie2(string cookie)         {             string Url = "https://sso.douyin.com/check_login/?service=https:%2F%2Fwww.douyin.com&aid=6383";             System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;             HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);  //创建一个链接             request.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)";             request.Referer = Url;             request.Headers.Add("Cookie", cookie);             HttpWebResponse response = request.GetResponse() as HttpWebResponse;  //获取反馈             StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8"));             string html = reader.ReadToEnd();             string has_login = Regex.Match(html, @"""has_login"":([\s\S]*?),").Groups[1].Value;               if (has_login == "true")             {                 reader.Close();                 label1.Text = "登录成功";                 string content = response.GetResponseHeader("Set-Cookie");                 Uri uri = new Uri("http://douyin.com");                 string cookies = CookieHelper.GetCookies(content, uri);                 return cookies;             }               else             {                 reader.Close();                 label1.Text = "登录失败";                 return "";               }               }

6、扫码后提示“请使用手机验证码登录”，实验结果获取cookie失败。只是提示已扫码。
二、利用CefSharp获取抖音cookie,并保存本地。
1、添加控件tabPage1。添加窗体载入事件，加载抖音网页，代码：

[C#] 纯文本查看 复制代码

?

1 2 3 4 5 6 7

private void Webbrowser_Load(object sender, EventArgs e)        {            browser = new ChromiumWebBrowser(get_code_url);            Control.CheckForIllegalCrossThreadCalls = false;            tabPage1.Controls.Add(browser);                    }

2、通过网页扫码提示登录成功，添加获取cookie按钮，调用获取cookie方法，并保存本地：

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

private void button5_Click(object sender, EventArgs e)        {            CookieVisitor visitor = new CookieVisitor();            visitor.SendCookie += Visitor_SendCookie;            ICookieManager cookieManager = browser.GetCookieManager();            cookieManager.VisitAllCookies(visitor);            MessageBox.Show("cookie已获取");            //dlchangee();            //this.Close();        }        public static string COOKIE = "";        private void Visitor_SendCookie(CefSharp.Cookie obj)        {            //obj.Domain.TrimStart('.') + "^" +            COOKIE += obj.Name + "=" + obj.Value + ";";            File.WriteAllText(AppDomain.CurrentDomain.BaseDirectory + @"cookie.txt", COOKIE, Encoding.Default);            textBox2.Text = COOKIE;            //string[] cookies1 = webbrowser.cookies.Split(';');        }          public class CookieVisitor : CefSharp.ICookieVisitor        {            public event Action<CefSharp.Cookie> SendCookie;            public void Dispose()            {              }              public bool Visit(CefSharp.Cookie cookie, int count, int total, ref bool deleteCookie)            {                deleteCookie = false;                SendCookie?.Invoke(cookie);                  return true;              }                      }

3、成功获取到cookie,但是由于CefSharp包太大，软件打包后不方便，不推荐此方法。
三、利用Selenium包获取cookie,
1、下载谷歌浏览器的chromedriver.exe放入软件根目录，在谷歌浏览器界面打开抖音主页扫码，
利用Selenium的IWebDriver自带获取cookie方法webDriver.Manage().Cookies.AllCookies;获取cookie,但是发生异常，异常提示
cookie的name为空，可利用webDriver.Manage().Cookies.DeleteCookieNamed("");去除cookie内空name,然后调用webDriver.Manage().Cookies.AllCookies;方法，以上消失。

public void login()         {                                    webDriver.Navigate().GoToUrl(get_code_url);             Thread.Sleep(10000);             ReadOnlyCollection<Cookie> cookies1;             while (true)             {                 if (webDriver.PageSource.Contains("退出登录"))                 {                 webDriver.Manage().Cookies.DeleteCookieNamed("");                 cookies1 = webDriver.Manage().Cookies.AllCookies;                 break;                 }                                              }                                        StringBuilder sb = new StringBuilder();             foreach (var item in cookies1)             {                 sb.Append(item.Name + "=" + item.Value + ";");               }             textBox1.Text = sb.ToString();                         File.WriteAllText(AppDomain.CurrentDomain.BaseDirectory + @"logincookie.txt", textBox1.Text, Encoding.Default);                                     }

2、然后利用获取的cookie，加载到浏览器就可以登录。

webDriver.Navigate().GoToUrl(get_code_url);            Thread.Sleep(10000);                        if (File.Exists(path))            {                                 string cookies2 = File.ReadAllText(path);                string[] cookieal3 = cookies2.Split(new string[] { ";" }, StringSplitOptions.None);                  foreach (var item in cookieal3)                {                    if (!string.IsNullOrEmpty(item) && !item.Equals("="))                    {                        string[] cookie = item.Split(new string[] { "=" }, StringSplitOptions.None);                        if (cookie.Length > 1)                        {                            OpenQA.Selenium.Cookie cook = new OpenQA.Selenium.Cookie(cookie[0].Trim(), cookie[1].Trim(), "", DateTime.Now.AddDays(1));                            webDriver.Manage().Cookies.AddCookie(cook);                        }                    }                  }                }            else {                  MessageBox.Show("请先登录");                return;            }

总结，本次实验，利用了三种方法，对抖音cookie进行了获取，第一种方法是利用HttpWebRequest，HttpWebResponse，提交请求的方式获取，由于方式特殊，被拦截，第二种方法获取也很方便，但nuget包巨大，不推荐，第三种方法，利用谷歌浏览器获取，对不熟悉操作的人也不是很方便，后两种方法，都获取成功。
