C# 调用FiddlerCore API抓包详解

下载：FiddlerCore

添加引用CertMaker.dll，BCMakeCert.dll，FiddlerCore4.dll

启动程序时 设置Fiddler代理127.0.0.1端口为8877，程序关闭时或不使用时关闭Fiddler代理，并清空代理设置；

第一次使用需安装Fiddler证书 InstallCertificate();

//启动fiddler设置代理，安装证书，此处SetIEProxy改变的为全局代理设置，若无需改变全局代理设置，可进行局部代理设置。
Fiddler.FiddlerApplication.BeforeRequest += FiddlerApplicaiton_BeforeRequest;
Fiddler.FiddlerApplication.BeforeResponse += FiddlerApplicaiton_BeforeResponse;
Fiddler.FiddlerApplication.AfterSessionComplete += FiddlerApplication_AfterSessionComplete;
Fiddler.FiddlerApplication.Startup(8877, false, true, true);
SetIEProxy();
InstallCertificate();

//关闭fiddler
Fiddler.FiddlerApplication.Shutdown();

//安装证书-安装完毕后删除CertMaker.dll,可避免重复安装
public static bool InstallCertificate()
{
    if (!CertMaker.rootCertExists())
    {
        if (!CertMaker.createRootCert())
            return false;
        if (!CertMaker.trustRootCert())
            return false;
    }
    CONFIG.IgnoreServerCertErrors = true;
    return true;
}

//卸载证书,通常不用
public static bool UninstallCertificate()
{
    if (CertMaker.rootCertExists())
    {
        if (!CertMaker.removeFiddlerGeneratedCerts(true))
            return false;
    }
    return true;
}

//请求前
public void FiddlerApplicaiton_BeforeRequest(Session oS)
{
    oS.bBufferResponse = true;
}

//请求中
public void FiddlerApplicaiton_BeforeResponse(Session oS)
{
    //解压
    oS.utilDecodeResponse();
}

//请求结束
public void FiddlerApplication_AfterSessionComplete(Session oS)
{
    
}

//设置IE代理
public bool SetIEProxy()
{
    try
    {
        Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Internet Settings", true);
        //设置代理可用 
        rk.SetValue("ProxyEnable", 1);
        //设置代理IP和端口 
        rk.SetValue("ProxyServer", "http=127.0.0.1:8877;https=127.0.0.1:8877");
        rk.Flush();//刷新注册表
        rk.Close();
        ActivateIEProxy();
        return true;
    }
    catch { return false; }
}

//清空IE代理设置
public bool SetCleanIEProxy()
{
    try
    {
        Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Internet Settings", true);
        rk.SetValue("ProxyEnable", 0);
        rk.Flush();//刷新注册表
        rk.Close();
        ActivateIEProxy();
        return true;
    }
    catch { return false; }
}

//激活IE设置
public void ActivateIEProxy()

    InternetSetOption(0, 39, IntPtr.Zero, 0);
    InternetSetOption(0, 37, IntPtr.Zero, 0);
