{
    "version": "1.0.0",
    "manifest_version": 2,
    "name": "Chrome Fiddler",
    "permissions": [
        "proxy",
        "tabs",
        "unlimitedStorage",
        "storage",
        "<all_urls>",

    ],
    "background": {
        "scripts": ["background.js"]
 },
    "minimum_chrome_version":"22.0.0"
}

background.js 是邏輯處理模塊

因?yàn)閿r截api 或者轉(zhuǎn)發(fā) 需要用的chrome的api

chrome.webRequest.onBeforeRequest.addListener(
   function(details) {
      //邏輯處理
   },
   { urls: ['<all_urls>']},
   ['blocking', 'extraHeaders', 'requestBody']
);

這個(gè)api的函數(shù) 接收的details參數(shù)

details.url 是api的接口

函數(shù)的返回

{cancel:true} 攔截請求
{redirectUrl:''} 轉(zhuǎn)發(fā)到指定url

寫selenium.chrome插件

新建一個(gè)netstand工程，然后引用

Selenium.WebDriver

復(fù)制以下代碼

/// <summary>
/// Add Fiddler extention
/// </summary>
/// <param name="options">Chrome options</param>
/// <param name="fiddlerOption">Proxy host</param>
public static void AddFiddler(this ChromeOptions options, FiddlerOption fiddlerOption)
{
    var backgroundProxyJs = ReplaceTemplates(background_js, fiddlerOption);

    if (!Directory.Exists("Plugins"))
        Directory.CreateDirectory("Plugins");

    var guid = Guid.NewGuid().ToString();

    var manifestPath = $"Plugins/manifest_{guid}.json";
    var backgroundPath = $"Plugins/background_{guid}.js";
    var archiveFilePath = $"Plugins/proxy_auth_plugin_{guid}.zip";

    File.WriteAllText(manifestPath, manifest_json);
    File.WriteAllText(backgroundPath, backgroundProxyJs);

    using (var zip = ZipFile.Open(archiveFilePath, ZipArchiveMode.Create))
    {
        zip.CreateEntryFromFile(manifestPath, "manifest.json");
        zip.CreateEntryFromFile(backgroundPath, "background.js");
    }

    File.Delete(manifestPath);
    File.Delete(backgroundPath);

    options.AddExtension(archiveFilePath);
}

private static string ReplaceTemplates(string str, FiddlerOption fiddlerOption)
{
    if (fiddlerOption.OnBeforeRequestOptions != null)
    {
        var beforeConfigs = Newtonsoft.Json.JsonConvert.SerializeObject(fiddlerOption.OnBeforeRequestOptions);
        str = str.Replace("{before_configs}", beforeConfigs);
    }
    return str;
}

上面的代碼主要是創(chuàng)建一個(gè)chrome擴(kuò)展zip包

然后再selenium.chrome啟動的時(shí)候傳進(jìn)去這個(gè)zip包的地址

使用方法

var driverBinary = @"D:\soft\chrome\chrome2\Chrome-bin\";
ChromeOptions options = new ChromeOptions
{
    BinaryLocation = Path.Combine(driverBinary, "chrome.exe")
};
Environment.SetEnvironmentVariable("webdriver.chrome.driver", driverBinary);
options.AddArgument("--disable-blink-features=AutomationControlled");
options.AddArguments("--disable-infobars");
List<string> ls = new List<string> { "enable-automation" };
options.AddExcludedArguments(ls);
#region Fillder
options.AddFiddler(new FiddlerOption
{
    OnBeforeRequestOptions = new List<FiddlerOnBeforeRequestOptions>
    {
        // 配置轉(zhuǎn)發(fā)
        new FiddlerOnBeforeRequestOptions
        {
            Match = "https://www.cnblogs.com/yudongdong/ajax/GetPostStat",//正則
            RedirectUrl = "http://localhost:5000/GetPostStat",//如果匹配成功則將requestBody轉(zhuǎn)發(fā)到這個(gè)url中去
            Cancel = false//如果配置了cancel=true那么轉(zhuǎn)發(fā)將無效，true的意思是直接攔截這次的請求,不去發(fā)送了
        },
        // 配置攔截
        new FiddlerOnBeforeRequestOptions
        {
            Match = "https://www.cnblogs.com/yudongdong/ajax/blogStats",
            Cancel = true//true的意思是直接攔截這次的請求,不去發(fā)送了
        },
    }
});
#endregion
var chrome = new ChromeDriver(driverBinary, options);

實(shí)現(xiàn)效果
