使用Watin更改IE实例的代理设置

Question

我知道我可以更改计算机全局代理设置Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings,以影响使用Watin创建的IE实例.

但有没有办法拦截IE浏览器发出的请求并通过代理运行它们？我的目标是运行IE的多个实例,每个实例都有自己的代理,这对于我上面的当前解决方案是不可能的.

WatiN IE 创建多个ProcessID（单实例 IE 创建多个进程 ID）。为了使用Fiddler Core覆盖 WatiN 的代理设置，我们需要获取由 WatiN IE 创建的所有子进程 ID。可以在此处找到帮助程序类PInvoke：获取窗口 \xe2\x80\x93 Svett Ralchev 类的所有子句柄。然后我们检查BeforeRequest中的所有进程 ID事件中的所有进程 ID，并等待 watin 进程 ID 覆盖代理设置。

    private void FiddlerApplication_BeforeRequest(Session sess)\n    {\n        //Debug.WriteLine("FiddlerApplication_BeforeRequest: " + sess.LocalProcessID.ToString());\n        if (WatinIEprocessHolder.ContainsKey(sess.LocalProcessID))\n        {                \n            //see http://stackoverflow.com/questions/14284256/how-to-manually-set-upstream-proxy-for-fiddler-core\n            sess["X-OverrideGateway"] = WatinIEprocessHolder[sess.LocalProcessID];\n        }\n    } \n

    private void this_FormClosing(object sender, FormClosingEventArgs e)\n    {\n        StopFiddler();\n    }\n\n    private void Form1_Load(object sender, EventArgs e)\n    {\n        this.FormClosing += this_FormClosing;\n\n        ProxyHolder = new List<string>();\n        ProxyHolder.Add("119.46.110.17:8080");\n        ProxyHolder.Add("178.21.112.27:3128");\n        ProxyHolder.Add("122.96.59.107:83");\n        ProxyHolder.Add("136.0.16.217:3127");\n        ProxyHolder.Add("198.52.199.152:7808");\n        ProxyHolder.Add("122.96.59.107:82");\n\n        StartFiddler();\n        System.Threading.Thread.Sleep(500);\n\n        for (var i = 0; i < ProxyHolder.Count; i++)\n        {\n            WhatIsMyIpThroughProxy(ProxyHolder[i]);\n            Application.DoEvents();\n            System.Threading.Thread.Sleep(500);\n        }\n        //WhatIsMyIpThroughProxy();\n    }\n\n    private Dictionary<int, string> WatinIEprocessHolder = new Dictionary<int, string>();\n    private List<string> ProxyHolder = null;\n\n    public void WhatIsMyIpThroughProxy(string ProxyIPandPort)\n    {\n\n        using (var browser = new IE(true))// we should not navigate now.
