在 Puppeteer Sharp 中程序完成时如何阻止浏览器关闭

How to stop browser from closing when the program completes in Puppeteer Sharp

我们正在为我们的客户提供密码管理解决方案。我们能够使用以下代码使用 puppeter sharp 成功地自动化用户名和密码。

但是程序执行后浏览器自动关闭。程序执行后有没有办法退出浏览器运行

static async Task Main(string[] args)
        {
            var options = new LaunchOptions { Headless = false, ExecutablePath = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", Args = new string[] { "--no-sandbox" } };

            using (var browser = await Puppeteer.LaunchAsync(options))
            using (var page = await browser.NewPageAsync())
            {
                // use page
                await page.GoToAsync("https://accounts.google.com/");
                //await page.WaitForNavigationAsync();

                // await page.WaitForSelectorAsync("type=email");
                //  await page.ClickAsync("type=email");

                //  await page.WaitForNavigationAsync();
                await Task.Delay(2000);
                //TODO : change to your email
                await page.TypeAsync("#identifierId", "someusername@gmail.com");
                await page.WaitForSelectorAsync("#identifierNext");
                await page.ClickAsync("#identifierNext");
                await Task.Delay(2000);

                await page.WaitForSelectorAsync(@"input[type='password']");
                await Task.Delay(2000);
                await page.ClickAsync(@"input[type='password']");
                await Task.Delay(2000);

                //TODO : change to your password
                await page.TypeAsync(@"input[name='password']", "somepassword");
                await Task.Delay(2000);
                await page.WaitForSelectorAsync("#passwordNext");
                await Task.Delay(2000);
                await page.ClickAsync("#passwordNext");
                await Task.Delay(2000);
                await page.WaitForNavigationAsync();
            }
        }

如果您想自动化浏览器,然后让它打开以供用户交互,您需要在 自动化之前启动浏览器 ,并将您的代码附加到该浏览器实例。这个问题提供了一些关于如何做到这一点的信息:
