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"``;

try
{
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); //创建一个链接

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
{

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：

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：

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)"``;
request.Referer = Url;
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
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;
}
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);
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;
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：

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"``);
}
public static string COOKIE = ""``;
private void Visitor_SendCookie(CefSharp.Cookie obj)
{
COOKIE += obj.Name + "=" + obj.Value + ";"``;
File.WriteAllText(AppDomain.CurrentDomain.BaseDirectory + @"cookie.txt"``, COOKIE, Encoding.Default);
textBox2.Text = COOKIE;
}
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。

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。

foreach (``var item in cookieal3)
{

{

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。
