Microsoft.Playwright web操作基础使用

 //如果没有下载驱动.可以使用以下代码自动安装 (以下代码仅供参考)          
//Microsoft.Playwright.Program.Main(new[] { "install" });
            var playwright = await Playwright.CreateAsync();
       //BrowserTypeLaunchPersistentContextOptions  不是必须的.供参考
            BrowserTypeLaunchPersistentContextOptions bto = new BrowserTypeLaunchPersistentContextOptions { Headless = false, ExecutablePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "chromedriver_win32", "chrome-win", "chrome.exe") };
            //bto.IgnoreDefaultArgs = new[] { "--enable-automation" };
            //bto.IgnoreAllDefaultArgs = true;
            var browser = await playwright.Chromium.LaunchPersistentContextAsync(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "chromedriver_win32", "webDir"), bto);
            //https://www.selenium.dev/documentation/webdriver/browsers/chrome/ 查询浏览器的可用参数

            var page = browser.Pages.First();


            await page.GotoAsync("https://fanyi.youdao.com/index.html#/");
            await page.AddScriptTagAsync(new PageAddScriptTagOptions() { Path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "files", "jquery-3.4.1.min.js") });
           //下载数据.
           var down = page.RunAndWaitForDownloadAsync(async () =>
                  {
                      await page.EvaluateAsync("$('.download .item:eq(0)').click()");
                  });
            await Task.WhenAny(down, Task.Delay(6 * 60 * 1000));
            var dd = await down;
            Stream sm = await dd.CreateReadStreamAsync();
            await browser.CloseAsync();
            await browser.DisposeAsync();
            playwright.Dispose();
