我可以帮您进行翻译。这段内容是关于设置 Fiddler 代理的，具体操作可以参考此链接：gist here。
代码如下：
代码如下：
public class ProxyConfig
{
private readonly string _secureEndpointHostname = IPAddress.Any.ToString();
private readonly int _secureEndpointPort = 4555;
private readonly int _port = 18882;
private static readonly ICollection<Session> AllSessions = new List<Session>();
private static Fiddler.Proxy _secureEndpoint;
private static readonly LoggerCnx Logger = new LoggerCnx();
private Action<string> onRequest;
public ProxyConfig()
{
}
public ProxyConfig(Action<string> onRequest)
{
this.onRequest = onRequest;
}
public void SetupProxyListener()
{
FiddlerApplication.SetAppDisplayName("FiddlerCoreProxyApp");
// This is a workaround for known issue in .NET Core - https://github.com/dotnet/coreclr/issues/12668
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("en-US");
// Simply echo notifications to the console. Because Fiddler.CONFIG.QuietMode=true
// by default, we must handle notifying the user ourselves.
//Fiddler.FiddlerApplication.OnNotification += delegate (object sender, NotificationEventArgs oNEA) { System.Diagnostics.Debug.WriteLine("** NotifyUser: " + oNEA.NotifyString); };
FiddlerApplication.Log.OnLogString += delegate (object sender, LogEventArgs oLEA) { Logger.Info("** LogString: " + oLEA.LogString); };
FiddlerApplication.BeforeRequest += delegate (Session session)
{
if (!CertMaker.rootCertIsTrusted())
{
CertMaker.trustRootCert();
}
if (onRequest != null)
{
onRequest(session.fullUrl);
}
// In order to enable response tampering, buffering mode MUST
// be enabled; this allows FiddlerCore to permit modification of
// the response in the BeforeResponse handler rather than streaming
// the response to the client as the response comes in.
session.bBufferResponse = false;
lock (AllSessions)
{
AllSessions.Add(session);
Logger.Info("Session: " + session.fullUrl);
}
session["X-AutoAuth"] = "(default)";
if ((session.oRequest.pipeClient.LocalPort == _secureEndpointPort) && (session.hostname == _secureEndpointHostname))
{
session.utilCreateResponseAndBypassServer();
session.oResponse.headers.SetStatus(200, "OK");
session.oResponse["Content-Type"] = "text/html; charset=UTF-8";
session.oResponse["Cache-Control"] = "private, max-age=0";
session.utilSetResponseBody("<html><body>Request for httpS://" + _secureEndpointHostname + ":" + _secureEndpointPort.ToString() + " received. Your request was:<br /><plaintext>" + session.oRequest.headers.ToString());
}
};
Logger.Info($"Starting {FiddlerApplication.GetVersionString()}...");
CONFIG.IgnoreServerCertErrors = true;
CONFIG.bCaptureCONNECT = true;
FiddlerApplication.Prefs.SetBoolPref("fiddler.network.streaming.abortifclientaborts", true);
FiddlerCoreStartupFlags startupFlags = FiddlerCoreStartupFlags.Default;
startupFlags = (startupFlags | FiddlerCoreStartupFlags.DecryptSSL);
startupFlags = (startupFlags | FiddlerCoreStartupFlags.AllowRemoteClients);
startupFlags = (startupFlags & ~FiddlerCoreStartupFlags.MonitorAllConnections);
startupFlags = (startupFlags & ~FiddlerCoreStartupFlags.CaptureLocalhostTraffic);
FiddlerApplication.Startup(_port, startupFlags);
Logger.Info("Created endpoint listening on port {0}", _port);
Logger.Info("Starting with settings: [{0}]", startupFlags);
Logger.Info("Gateway: {0}", CONFIG.UpstreamGateway.ToString());
// Create a HTTPS listener, useful for when FiddlerCore is masquerading as a HTTPS server
// instead of acting as a normal CERN-style proxy server.
_secureEndpoint = FiddlerApplication.CreateProxyEndpoint(_secureEndpointPort, true, _secureEndpointHostname);
if (null != _secureEndpoint)
{
Logger.Info("Created secure endpoint listening on port {0}, using a HTTPS certificate for '{1}'", _secureEndpointPort, _secureEndpointHostname);
}
}
}
该软件的目的是捕获并分析来自Windows、Mac OS X、Android和iOS浏览器（主要是Chrome、Firefox和Safari，包括桌面设备和移动设备）的流量。
到目前为止，它似乎可以在以下设备上运行：
- Windows浏览器：Chrome、Firefox。但不支持IE和Edge
- Android：Chrome
- Mac OS：Chrome、Firefox。但不支持Safari
- iOS：无法运行
在我的日志文件中，我看到Fiddler记录了一些错误，这些错误出现在不能正常工作的浏览器上（适用于所有设备）。以下是一个HTTPS请求的示例：
2018-02-14 17:25:50.3860 | INFO | ** LogString: !SecureClientPipeDirect failed: System.IO.IOException Authentication failed because the remote party has closed the transport stream. for pipe (CN=*.optimizely.com, O=DO_NOT_TRUST_BC, OU=Created by http://www.fiddler2.com)
根据我最近几天阅读的内容，试图找出解决方案，原因可能是设备上不信任证书。
测试正在使用BrowserStack进行，使用他们提供的名为BrowserStack Local的功能。有关详细信息，请单击此处和此处。
现在我的问题可以分为桌面和移动设备：
- 为什么Chrome和Firefox能够进行HTTPS请求，而IE、Edge和Safari无法做到？
- 特别针对iOS，这里有一个iOS Fiddler文档此处，指定了配置设备所需的步骤。然而，正如我已经提到的，我没有使用内部iOS设备，而是由BrowserStack提供的物理设备。有没有办法在iOS设备上以编程方式信任证书（iOS 9.x、iOS 10.x、iOS 11.x）？
有没有任何解决方法可供我使用？
