关于获取cookie方法的实验（以抖音pc端为例）
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：
string url = "https://sso.douyin.com/get_qrcode/?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&service=https:%2F%2Fwww.douyin.com&is_vcd=1&fp=kesopiod_fB4eRss7_Stsz_434j_AiPQ_6xhtUsqmqpSN";
2、请求二维码代码：
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：
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.Value;
string redirect_url = Regex.Match(html, @"""redirect_url"":""([\s\S]*?)""").Groups.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：
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.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：
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：
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.Trim(), cookie.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。 看起来有点复杂。学习一下 感谢大佬分享,新技能,已经get√{:1_921:} 回去试试 最近刚好也在学习获取cookie方法，有用！ 厉害，谢谢分享 学习一下，感谢分享 方法1系统繁忙扫码不行。 等待机会 发表于 2022-7-20 21:15
方法1系统繁忙扫码不行。
方法1通过接口 直接扫的 绕不过去的 还是没学会
