Selenium驱动Chrome自动化

1.环境准备

1.1 开发工具

Visual Studio 2017 

1.2 驱动下载地址

Chrome驱动下载地址：https://npm.taobao.org/mirrors/chromedriver/

找到对应电脑的版本下载，比如我本机是Windows 操作系统、Chrome 92版本的，那下载地址就是https://npm.taobao.org/mirrors/chromedriver/92.0.4515.43/chromedriver_win32.zip

2.库安装

需要使用库的项目，右键->管理Nuget程序包

3.创建驱动对象

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Diagnostics;
using System.Linq;/*

namespace ChromeDriver
{/// 
/// /// 
public class ChromeDriver{/// 
/// 获取Chrome驱动对象/// 
/// IEDriverServer.exe 的存放路径/// public IWebDriver GetChromeDriver(string WebDriverPath = "", ChromeOptions options = null){if (string.IsNullOrWhiteSpace(WebDriverPath)){WebDriverPath = ".";}if (options == null){options = new ChromeOptions();// 隐藏Chrome 正在受到自动化软件控制，避免前端检测 76之前的写法options.AddArgument("disable-infobars");// 隐藏Chrome 正在受到自动化软件控制，避免前端检测 76之后的写法options.AddExcludedArgument("enable-automation");options.AddAdditionalCapability("useAutomationExtension", false);// 设置每次下载时，弹窗选择下载路径options.AddUserProfilePreference("download.prompt_for_download", true);}var service = ChromeDriverService.CreateDefaultService(WebDriverPath);service.HideCommandPromptWindow = true;var driver = new OpenQA.Selenium.Chrome.ChromeDriver(service, options);if (driver != null){driver.Manage().Window.Maximize();driver.Manage().Timeouts().PageLoad = TimeSpan.FromMilliseconds(60000);driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(1500);driver.Manage().Timeouts().AsynchronousJavaScript = TimeSpan.FromMilliseconds(60000);}return driver;}/// 
/// 关闭驱动/// 
public void CloseChromeDriver(){Process[] pros = Process.GetProcessesByName("chromedriver");if (pros.Length > 10){var prosOrder = pros.OrderBy(item => { return item.StartTime; }).ToArray();for (int i = 10; i < prosOrder.Length; i++){prosOrder[i].Kill();}}}}
}

4.驱动页面元素

using Common;
using OpenQA.Selenium;
using OpenQA.Selenium.Interactions;
using OpenQA.Selenium.Support.Events;
using OpenQA.Selenium.Support.UI;
using System;
using System.Collections.Generic;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading;/*
