Selenium.Chrome相关配置及用法

一、全局配置

options.AddArgument("--no-sandbox");//不在沙盒中运行
options.AddArgument("--headless");//浏览器不提供可视化页面，桌面和状态栏都不会浏览器窗口，静默模式
options.AddArgument("--disable-dev-shm-usage");//克服资源有限的问题
options.AddArgument("--disable-images");//过滤掉图片加载，使页面加载更快
//关闭浏览器头部提示的正在被控制
options.AddExcludedArgument("enable-automation");
options.AddAdditionalCapability("useAutomationExtension", false);
//设置异步加载，异步加载就是不等页面加载完毕，只要页面上出现你所要的值，哪怕页面只渲染了20%，会马上拿到你指定的值，然后就可以进行下一个页面的爬去，速度惊人的快。如果不设置异步加载，经常是因为页面一个广告或图片或JS未加载完毕页面会一直转一直不会去拿你所要的值，而且很多时候还会超时，眼看着页面上有值但是就是拿不到的那种。
options.PageLoadStrategy = PageLoadStrategy.None;

二、页面打开时执行一段JS达到搞事情的目的。

using (driver = new OpenQA.Selenium.Chrome.ChromeDriver(options)){
((OpenQA.Selenium.Chrome.ChromeDriver)driver).ExecuteChromeCommand("Page.addScriptToEvaluateOnNewDocument", new Dictionary<string, object> { { "source", @"Object.defineProperty(navigator, 'webdriver', {get: () => false})" } });。。。。。
}

这样子去设置js脚本会在页面的JS执行之前优先执行我们的JS，好多反爬虫的网站经常会进行一些检测，我们可以根据分析去做一些处理，使其检测失效。

三、使用代理

在chrome里面使用带用户名和密码的代理，需要使用插件去实现，看一下google插件的文档，其实还是挺好实现的。给一段生成插件的代码：

/// <summary>
/// 生成插件
/// </summary>
/// <param name="ip"></param>
/// <param name="port"></param>
/// <param name="userName"></param>
/// <param name="passWord"></param>
public void GeneratePlug(string ip="",string port="",string userName="",string passWord="") {try{string FileName = Path.GetDirectoryName(Application.ExecutablePath) + "\\proxy.zip";string BackGroundJs = @"var config = {mode: 'fixed_servers',rules: {singleProxy: {scheme: 'http',host: 'mimvp_proxy_host',port: parseInt(mimvp_proxy_port)},bypassList: ['{0}']}};chrome.proxy.settings.set({value: config, scope: 'regular'}, function() {});function callbackFn(details) {return {authCredentials: {username: 'mimvp_username',password: 'mimvp_password'}};}chrome.webRequest.onAuthRequired.addListener(callbackFn,{urls: ['<all_urls>']},['blocking']);".Replace("{0}", string.Join(",", Sites).Replace(",", "','"));string ManiFest = "{\"version\": \"1.0.0\",\"manifest_version\": 2,\"name\": \"Chrome Proxy\",\"permissions\": [\"proxy\",\"tabs\",\"unlimitedStorage\",\"storage\",\"<all_urls>\",\"webRequest\",\"webRequestBlocking\"],\"background\": {\"scripts\": [\"background.js\"]},\"minimum_chrome_version\":\"22.0.0\"}";BackGroundJs =BackGroundJs.Replace("mimvp_proxy_host", ip).Replace("mimvp_proxy_port", port).Replace("mimvp_username", userName).Replace("mimvp_password", passWord);List<MemoryStream> ms = new List<MemoryStream> {new MemoryStream(System.Text.Encoding.UTF8.GetBytes(BackGroundJs)),new MemoryStream(System.Text.Encoding.UTF8.GetBytes(ManiFest))};List<string> lt = new List<string> { "background.js", "manifest.json" };Compress(ms, lt, FileName);}catch (Exception ex) { }
}

插件生成完毕后需要

options.AddExtension(FileName);

这样的方式进行设置，FileName就是插件的文件地址。

四、隐藏黑色的命令行窗口

     [DllImport("user32.dll", EntryPoint = "FindWindow")]private extern static IntPtr FindWindow(string lpClassName, string lpWindowName);[DllImport("user32.dll", EntryPoint = "SendMessage")]public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);public const int SW_HIDE = 0;public const int SW_SHOW = 5;[DllImport("user32.dll", EntryPoint = "ShowWindow")]public static extern int ShowWindow(IntPtr hwnd, int nCmdShow);public void HideWnd(){IntPtr hwd = GetWindowHandle();ShowWindow(hwd, SW_HIDE);}/// <summary>/// 获取窗口句柄/// </summary>/// <returns></returns>public IntPtr GetWindowHandle(){string name = Path.GetDirectoryName(Application.ExecutablePath) + "\\chromedriver.exe";IntPtr hwd = FindWindow(null, name);//log(hwd.ToString());//log(name);return hwd;}/// <summary>/// 关闭chromedriver窗口/// </summary>public void CloseWindow(){try{IntPtr hwd = GetWindowHandle();SendMessage(hwd, 0x10, 0, 0);}catch { }}

没错，就是使用windows API隐藏，桌面和任务栏都不会出现黑窗口。使用的时候，注意在程序最后关闭的时候即使调用CloseWindow进行窗口关闭。
