设置好Fiddler，部分https抓包时，显示 Tunnel to 443，注意不是全部，如果是全部显示Tunnel to 443，那需要把证书推送到系统证书里面。
1.打开 Fiddler ，找到 FiddlerScript标签，Go to： 这里选 OnBeforeRequest
.
在这个方法的末尾加上如下代码：
var hosts = ‘zkd.me develop.dog‘; FiddlerApplication.Log.LogFormat("Logger session {0}, Url: {1}, isHttps: {2}, port: {3}", oSession.id, oSession.fullUrl, oSession.isHTTPS, oSession.port); if(hosts.indexOf(oSession.host) > -1){ FiddlerApplication.Log.LogFormat("Capture session {0}, Url: {1}, isHttps: {2}, port: {3}", oSession.id, oSession.fullUrl, oSession.isHTTPS, oSession.port); if(oSession.HTTPMethodIs(‘CONNECT‘)){ FiddlerApplication.Log.LogString(‘create fake tunnel response‘); oSession[‘x-replywithtunnel‘] = ‘FakeTunnel‘; return; } if (oSession.isHTTPS){ FiddlerApplication.Log.LogString(‘switch https to http request‘); oSession.fullUrl = oSession.fullUrl.Replace("https://","http://"); oSession.port = 80; } FiddlerApplication.Log.LogFormat("Processed session {0}, Url: {1}, isHttps: {2}, port: {3}", oSession.id, oSession.fullUrl, oSession.isHTTPS, oSession.port); } FiddlerApplication.Log.LogFormat("Logger session {0}, Url: {1}, isHttps: {2}, port: {3}", oSession.id, oSession.fullUrl, oSession.isHTTPS, oSession.port);
var hosts = ‘zkd.me develop.dog‘;
这里需要改成我们自己的要抓包的域名
2.修改好后，一定要点 Save Script 这个按钮，要不然改了没用
//如何让HTTP请求和HTTPS请求显示不一样的颜色？
if(oSession.isHTTPS && oSession.url.indexOf(oSession.host)> -1){ oSession["ui-color"] = "blue"; } if(!oSession.isHTTPS && oSession.url.indexOf(oSession.host)> -1){ oSession["ui-color"] = "green"; }
