Question

如何直接在pdf中执行保存此页面？我知道selenium无法控制chrome对话框......还有另外一种方法吗？

Answer 1

您可以直接将请求发送到不包含Selenium的URL，并获取包含PDF文件内容的字节数组。之后，您可以使用某些PDF库读取文件内容（看起来像ITextSharp很受欢迎）。

Answer 2

在Chrome浏览器中，所有对话框弹出窗口都是html页面，因此您可以使用Selenium单击它们。在您的情况下，您可以导航到页面，模拟按Ctrl + P键盘按钮，切换到打印对话框窗口，单击更改按钮以更改打印机，单击保存到PDF，单击保存按钮，然后单击＆＃34;另存为＆＃34 ;框显示 - 模拟按Enter键按钮实际保存文件。我不做C＃，但这就是Java中的样子，事实上我已经测试了它，它确实有效：

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_P);
robot.keyRelease(KeyEvent.VK_P);
robot.keyRelease(KeyEvent.VK_CONTROL);

// get current browser window handles and switch to window with handle that is last in the list
Set<String> windowHandles = driver.getWindowHandles();
for (String handle : windowHandles) {
    driver.switchTo().window(handle);
}

driver.findElement(By.xpath("//button[contains(text(), 'Change')]")).click();
driver.findElement(By.xpath("//span[contains(text(), 'Save as PDF')]")).click();
driver.findElement(By.xpath("//button[contains(text(), 'Save')]")).click();

// you might need to add waiter here that waits a second, since script is too fast
// and needs to wait for save dialog box to be shown

robot.keyPress(KeyEvent.VK_ENTER);

另一种保存方法是命令Chrome浏览器将其保存到磁盘，而不是打开页面。以下是方法：

ChromeOptions chromeOptions = new ChromeOptions();
// this will make automatically download to the default folder.
chromeOptions.AddUserProfilePreference("plugins.always_open_pdf_externally", true);  
ChromeDriverService chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriver = new ChromeDriver(chromeDriverService, chromeOptions);

var downloadsPath = KnownFolders.Downloads.Path;
var generatedFilePngs = Directory.GetFiles(downloadsPath, string.Format("{0}*.pdf", "TheNameOfYourPDF"));

以下代码将有助于在 Selenium c# 中将页面另存为 pdf。

using OpenQA.Selenium;

using OpenQA.Selenium.Chrome;

protected void PDFconversion(ChromeDriver driver, string root, string rootTemp)
{
    //Grid.Rows.Add(TxtBxName.Text, TxtBxAddress.Text);
    try
    {
        IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
        Thread.Sleep(500);
        js.ExecuteScript("setTimeout(function() { window.print(); }, 0);");
        Thread.Sleep(500);
        driver.SwitchTo().Window(driver.WindowHandles.Last());
        Thread.Sleep(500);
        string JSPath = "document.querySelector('body>print-preview-app').shadowRoot.querySelector('#sidebar').shadowRoot.querySelector('#destinationSettings').shadowRoot.querySelector('#destinationSelect').shadowRoot.querySelector('print-preview-settings-section:nth-child(9)>div>select>option:nth-child(3)')";
        Thread.Sleep(500);
        IWebElement PrintBtn = (IWebElement)js.ExecuteScript($"return {JSPath}");
        Thread.Sleep(500);
        PrintBtn.Click();
        string JSPath1 = "document.querySelector('body>print-preview-app').shadowRoot.querySelector('#sidebar').shadowRoot.querySelector('print-preview-button-strip').shadowRoot.querySelector('cr-button.action-button')";
        Thread.Sleep(1000);
        IWebElement PrintBtn1 = (IWebElement)js.ExecuteScript($"return {JSPath1}");
        PrintBtn1.Click();
        Thread.Sleep(1000);
        SendKeys.Send("{HOME}");
        SendKeys.Send(rootTemp + "\\" + "result.pdf"); // Path
        SendKeys.Send("{TAB}");
        SendKeys.Send("{TAB}");
        SendKeys.Send("{TAB}");
 
        SendKeys.Send("{ENTER}");
        Thread.Sleep(1000);
   
    }
    catch (Exception ex)
    {


    }

}
