C# 调用FiddlerCore实现http/https抓包-Toy模板网

这篇具有很好参考价值的文章主要介绍了C# 调用FiddlerCore实现http/https抓包。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

FiddlerCore是 Telerik 的跨平台 .NET 库，它允许捕获和修改 HTTP/HTTPS 流量。使用 FiddlerCore 的一些最流行的应用程序是 Telerik Fiddler（基于 .NET Framework 并在 Windows 上运行）和 Fiddler Everywhere（基于 .NET Core 并在 Windows、Mac 和 Linux 上运行）。

关键信息：FiddlerCore跨平台.net库，可以捕获http/https

NuGet安装：

c# fiddler,C#,.net

界面设计：

c# fiddler,C#,.net

启动捕获：

        public void startFiddler()
        {
            if (!FiddlerApplication.IsStarted())
            {
                FiddlerApplication.AfterSessionComplete += FiddlerApplication_AfterSessionComplete;
                FiddlerApplication.BeforeRequest += FiddlerApplication_BeforeRequest;
                FiddlerApplication.Startup(8888, true, true, true);
            }
            else
            {
                appendtext("fiddler is running...");
            }
        }

停止捕获：

        public void stopFiddler()
        {
            if (FiddlerApplication.IsStarted())
            {
                FiddlerApplication.Shutdown();

            }
        }

安装证书：

        public void install()
        {
            if (!CertMaker.rootCertExists())
            {
                CertMaker.createRootCert();
                CertMaker.trustRootCert();
            }
        }

证书移除：

        public void remove()
        {
            if (CertMaker.rootCertExists())
            {
                CertMaker.removeFiddlerGeneratedCerts();
            }
        }

两个事件函数：

        private void FiddlerApplication_BeforeRequest(Session oSession)
        {
            if (oSession.RequestMethod == "POST"||oSession.RequestMethod=="GET")
            {

                string url = oSession.fullUrl;
                string body = oSession.GetRequestBodyAsString();
                string header = oSession.RequestHeaders.ToString();
                appendtext(url);
                appendtext(header);
                appendtext(body);

            }
        }

        private void FiddlerApplication_AfterSessionComplete(Session oSession)
        {
            if (oSession.RequestMethod == "POST" || oSession.RequestMethod == "GET")
            {
                string body = oSession.GetResponseBodyAsString();
                appendtext(body);
                appendtext(tmp);
            }

        }
