Fidder插件自动生成爬虫代码（C#）

 原创，效果如下：

 

1、新建项目，并添加Fidder.exe的引用：

 2、添加代码

[assembly: Fiddler.RequiredVersion("2.2.8.6")]
using Fiddler;
using System;
using System.Windows.Forms;
public class MyExtension : IHandleExecAction, IFiddlerExtension
{
    private TabPage tabPage; //创建插件的选项卡页
    private UserControl myCtrl; //UserControl
    public MyExtension()
    {
        #region makeUC
        var uc = new System.Windows.Forms.UserControl();
        var txtCode = new System.Windows.Forms.RichTextBox();
        txtCode.Dock = System.Windows.Forms.DockStyle.Fill;
        txtCode.Location = new System.Drawing.Point(0, 0);
        txtCode.Name = "txtCode";
        txtCode.Size = new System.Drawing.Size(150, 150);
        uc.Controls.Add(txtCode);
        #endregion
        //构造函数中实例化对象
        this.myCtrl = uc;
        this.myCtrl.Dock = DockStyle.Fill;
        this.tabPage = new TabPage("Coder");//选项卡的名字为Test
    }
    public void OnLoad()
    {
        //将用户控件添加到选项卡中
        this.tabPage.Controls.Add(this.myCtrl);
        //为选项卡添加icon图标，这里使用Fiddler 自带的
        this.tabPage.ImageIndex = (int)Fiddler.SessionIcons.Timeline;
        //将tabTage选项卡添加到Fidder UI的Tab 页集合中
        FiddlerApplication.UI.tabsViews.TabPages.Add(this.tabPage);
        FiddlerApplication.UI.lvSessions.SelectedIndexChanged += LvSessions_SelectedIndexChanged;
    }
    public void OnBeforeUnload()
    {

    }
    private void LvSessions_SelectedIndexChanged(object sender, EventArgs e)
    {
        System.Text.StringBuilder sb = new System.Text.StringBuilder();

        var sessions = FiddlerApplication.UI.GetSelectedSessions();
        if (sessions != null)
        {
            if (sessions.Length > 0)
            {
                sb.Append("            HttpHelper httpHelper = new HttpHelper();\r\n");
            }
            foreach (var item in sessions)
            {
                sb.Append(Raw2Code(item.RequestHeaders.ToString(true, true, true)));
            }
        }
        myCtrl.Controls[0].Text = sb.ToString();
    }
    private string Raw2Code(string rawText)
    {
        return "请加QQ：351392535；www.shujucaiji.cn";
    }
    bool IHandleExecAction.OnExecAction(string sCommand)
    {
        string[] strArray = Utilities.Parameterize(sCommand);
        var aa = FiddlerApplication.UI.GetAllSessions();
        return true;
    }
    //public void AutoTamperRequestBefore(Session oSession)
    //{
    //    /*在这编写请求之前需要执行的code */
    //}
    //public void AutoTamperRequestAfter(Session oSession)
    //{
    //    /*在这编写请求之后需要执行的code */
    //}
    //public void AutoTamperResponseBefore(Session oSession)
    //{
    //    /*在这编写响应之前需要执行的code */

    //    myCtrl.txtCode.Text = Raw2Code(oSession.RequestHeaders.ToString(true, true, true));
    //}
    //public void AutoTamperResponseAfter(Session oSession)
    //{
    //    /*在这编写响应之后需要执行的code */
    //}
    //public void OnBeforeReturningError(Session oSession)
    //{
    //    /*在这编写有错误返回时需要执行的code */
    //}
}

 3、编译并将dll拷贝到Fidder的Script目录下。

       或者在：后期生成事件命令行中添加：copy "$(TargetPath)" "%ProgramFiles%\Fiddler2\Scripts\$(TargetFilename)"

4、打开Fidder
