• cefSharp 获取和设置 cookie

    一 看一下界面：

    button名 :  button1

    textbox名:  textBox_cookie

    二 html页面

    1. <html>
    2. <head>
    3. <title>page1title>
    4. head>
    5. <body>
    6. this is page 111
    7. <br><a href="page4.html">to page4a>
    8. <script language=javascript>
    9.  
    10. document.cookie="username=Tom&age=22";
    11.  
    12. script>
    13. body>
    14. html>
    15.

    三 代码

    两个方案

    1，获取js内容的方式

    1. private void button1_Click(object sender, EventArgs e)
    2.         {
    3.             Task<CefSharp.JavascriptResponse> t = webBrower.EvaluateScriptAsync("document.cookie");
    4.             t.Wait();
    5.             var cookie = t.Result.Result;
    6.  
    7.         }

    2，cefSharp的标准方式

    1. public partial class Form1 : Form
    2.     {
    3.         public Form1()
    4.         {
    5.             InitializeComponent();
    6.             this.Load += Form1_Load;
    7.         }
    8.  
    9.         ChromiumWebBrowser webBrower = null;
    10.         string cookies;
    11.         private void Form1_Load(object sender, EventArgs e)
    12.         {
    13.             //初始化配置
    14.             string path = "";
    15.             webBrower = new ChromiumWebBrowser(path);
    16.             webBrower.Dock = DockStyle.Fill;// 填充方式
    17.             webBrower.FrameLoadEnd += WebBrower_FrameLoadEnd;
    18.             button1.Click += button1_Click;
    19.             this.Controls.Add(webBrower);
    20.             //加载测试页面
    21.             webBrower.Load("http://localhost/page1.html");
    22.  
    23.             //模拟写入cookie(测试页面，也有一个cookie)
    24.             var cookieManager = CefSharp.Cef.GetGlobalCookieManager();
    25.             cookieManager.SetCookieAsync("http://localhost", new CefSharp.Cookie()
    26.             {
    27.                 Domain = "localhost",
    28.                 Name = "1",
    29.                 Value = "2",
    30.                 Expires = DateTime.MinValue
    31.             });
    32.         }
    33.  
    34.         //加载完成后，获取cookie
    35.         private void WebBrower_FrameLoadEnd(object sender, CefSharp.FrameLoadEndEventArgs e)
    36.         {
    37.             //注册获取cookie回调事件
    38.             ICookieManager cookieManager = webBrower.GetCookieManager();
    39.             CookieVisitor visitor = new CookieVisitor();
    40.             visitor.SendCookie += visitor_SendCookie;
    41.             cookieManager.VisitAllCookies(visitor);
    42.  
    43.         }
    44.  
    45.         /// 回调事件
    46.         private void visitor_SendCookie(CefSharp.Cookie obj)
    47.         {
    48.             cookies += obj.Domain.TrimStart('.') + "^" + obj.Name + "^" + obj.Value + "\r\n";
    49.         }
    50.  
    51.         //cefsharp 获取cookie的方法
    52.         public class CookieVisitor : CefSharp.ICookieVisitor
    53.         {
    54.             public event Action SendCookie;
    55.  
    56.             public void Dispose()
    57.             {
    58.  
    59.             }
    60.             public bool Visit(CefSharp.Cookie cookie, int count, int total, ref bool deleteCookie)
    61.             {
    62.                 deleteCookie = false;
    63.                 if (SendCookie != null)
    64.                 {
    65.                     SendCookie(cookie);
    66.                 }
    67.  
    68.                 return true;
    69.             }
    70.         }
    71.  
    72.         //cookie放到text_cookie上
    73.         private void button1_Click(object sender, EventArgs e)
    74.         {
    75.             this.textBox_cookie.Text = cookies;
    76.  
    77.         }
    78.  
    79.  
    80.     }

    PS：如果想在FrameLoadEnd事件中显示

    那么代码需要委托，

    1 Load增加如下

    1. public Action GetCookie;
    2.         private void Form1_Load(object sender, EventArgs e)
    3.         {
    4.             //绑定获取cookie的委托
    5.             GetCookie = () =>
    6.             {
    7.                 Task t = webBrower.EvaluateScriptAsync("document.cookie");
    8.                 t.Wait();
    9.                 var cookie = t.Result.Result;
    10.  
    11.                 this.textBox_cookie.Text = cookie.ToString();
    12.             };
    13.         }

    2 WFrameLoadEnd增加如下

    1. private void WebBrower_FrameLoadEnd(object sender, CefSharp.FrameLoadEndEventArgs e)
    2.         {
    3.  
    4.             this.BeginInvoke(GetCookie);
    5.         }
