如何使用selenium webdriver在chrome中下载pdf文件

Question

我想使用硒下载chrome中的pdf。

System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir")  
               + System.getProperty("file.separator")
               + "BrowserDrivers"
               + System.getProperty("file.separator")
               + "chromedriver.exe");

String downloadFilepath = "C:\\Users\\Vinod\\Downloads";

HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);

//Save Chrome Opions
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromeOptionsMap = new HashMap<String, Object>();
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--test-type");


DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(ChromeOptions.CAPABILITY, chromeOptionsMap);
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);


driver = new ChromeDriver(cap);
driver.get(url);

我尝试了上述代码，但不起作用

Answer 1

您可以加载此页面并使用硒导航更改设置：

chrome://settings/content/pdfDocuments

Answer 2

以下是任何使用. NET的人的C#选项

var tsTimeout = new TimeSpan(0, 5, 0);

ChromeOptions chromeOptions = new ChromeOptions(); 
chromeOptions.AddUserProfilePreference("download.default_directory", _downloadFolder); 
chromeOptions.AddUserProfilePreference("download.prompt_for_download", false); 
chromeOptions.AddUserProfilePreference("download.directory_upgrade", true); 
chromeOptions.AddUserProfilePreference("plugins.plugins_disabled", "Chrome PDF Viewer"); 
chromeOptions.AddUserProfilePreference("plugins.always_open_pdf_externally", true);

_driver = new ChromeDriver(CWebCrawler.WebCrawlerRootFolder, chromeOptions, tsTimeout);

Answer 3

您可以将其设置为 false 以避免自动 pdf 预览，如下所示（ruby 示例）：

caps = Selenium::WebDriver::Remote::Capabilities.chrome(
        "chromeOptions" => {           
            'args' => ['disable-gpu', "--window-size=1920,1080"],
            prefs: {
                "download.prompt_for_download": false,
                "download.directory_upgrade": true,
                "plugins.always_open_pdf_externally": true,
                "download.default_directory": DownloadHelpers::PATH.to_s
            }
        }
    )
Capybara::Selenium::Driver.new(
        app,
        browser: :chrome,
        desired_capabilities: caps
    )
