打印页面

无论是共享信息还是维护档案，打印网页都是一项常见任务。 Selenium 通过其 PrintOptions、PrintsPage 和 browsingContext 类简化了这一过程，这些类为网页自动打印提供了灵活直观的接口。 这些类使得用户可以配置打印首选项，如页面布局、页边距和缩放比例，以确保输出满足特定要求。

配置

方向

通过 getOrientation() 和 setOrientation() 方法，可以获取/设置页面方向（PORTRAIT 或 LANDSCAPE）。

        driver.get("https://www.selenium.dev/");
        PrintOptions printOptions = new PrintOptions();
        printOptions.setOrientation(PrintOptions.Orientation.LANDSCAPE);
        PrintOptions.Orientation current_orientation = printOptions.getOrientation();

        public void TestOrientation()
        {
            IWebDriver driver = new ChromeDriver();
            driver.Navigate().GoToUrl("https://selenium.dev");
            PrintOptions printOptions  = new PrintOptions();
            printOptions.Orientation = PrintOrientation.Landscape;
            PrintOrientation currentOrientation = printOptions.Orientation;
        }

            printOptions.AddPageRangeToPrint("1-3"); // add range of pages
            printOptions.AddPageToPrint(5); // add individual page

打印

配置好打印选项后，就可以打印页面了。为此，您可以调用打印功能，生成网页的 PDF 表示形式。 生成的 PDF 文件可以保存到本地存储器中，以便进一步使用或分发。 使用 PrintsPage() 时，打印命令将以 base64 编码格式返回 PDF 数据，该格式可以解码并写入所需位置的文件，而使用 BrowsingContext() 时将返回字符串。

目前可能有多种实现方式，这取决于您所选择的语言。例如，Java 可以使用 BrowingContext() 或 PrintsPage() 进行打印。两者都将 PrintOptions() 对象作为一个参数。

注意：BrowsingContext() 是 Selenium BiDi 实现的一部分。为启用 BiDi，请参见启用 Bidi

PrintsPage()

        driver.get("https://www.selenium.dev/");
        PrintsPage printer = (PrintsPage) driver;
        PrintOptions printOptions = new PrintOptions();
        Pdf printedPage = printer.print(printOptions);
        Assertions.assertNotNull(printedPage);

BrowsingContext()

        BrowsingContext browsingContext = new BrowsingContext(driver, driver.getWindowHandle());
        driver.get("https://www.selenium.dev/selenium/web/formPage.html");
        PrintOptions printOptions = new PrintOptions();
        String printPage = browsingContext.print(printOptions);
