下载MP4文件而不是使用ChromeDriver播放？

Question

我正在使用ChromeWeb驱动程序2.10 chromedriver_win32。使用SeleniumWebDriver 2.31压缩。2.

启用详细日志记录后，似乎期望的能力（https://sites.google.com/a/chromium.org/chromedriver/capabilities）传递得很好，

[1.174][FINE]:      Initializing session with capabilities {

   "browserName": "chrome",

   "chrome.switches": [  ],

   "chromeOptions": {

      "args": [  ],

      "binary": "",

      "extensions": [  ],

      "prefs": {

         "download.default_directory": "C:\\Downloads",

         "download.directory_upgrade": "true",

         "download.extensions_to_open": "",

         "download.prompt_for_download": "false"

      }

   },

   "javascriptEnabled": true,

   "platform": "WINDOWS",

   "version": ""

}

但Chrome Web驱动程序正在播放*。mp4而不是下载。

我尝试过如何使用SeleniumWebDriver设置Chrome首选项的解决方案。网络绑定？但它似乎不适用于较新的Chrome Web驱动程序版本，如果我尝试使用selenium-dotnet-2.31，它就会崩溃。2和chromedriver_win_26.0。1383.0.

有人有什么建议吗？

Answer 1

这对我来说非常有效：

DesiredCapabilities cap = DesiredCapabilities.firefox();

FirefoxProfile fprofile= new FirefoxProfile();
fprofile.setPreference("browser.download.folderList",2);  //0-desktop,1-file download folder,2-specified location
fprofile.setPreference("browser.download.manager.showWhenStarting", false); //prevent download file window
fprofile.setPreference("browser.download.dir","E:\\Downloadfilebyprogram");
fprofile.setPreference("browser.download.manager.focusWhenStarting", false);
//fprofile.setPreference("browser.helperApps.alwaysAsk.force", false);
//fprofile.setPreference("browser.download.manager.closeWhenDone", true);
//fprofile.setPreference("browser.download.manager.useWindow", false);
//fprofile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);
//fprofile.setPreference("browser.helperApps.neverAsk.openFile,","application/vnd.ms-excel");
fprofile.setPreference("browser.helperApps.neverAsk.saveToDisk","application/vnd.ms-excel");
fprofile.setPreference("browser.download.manager.alertOnExeOpen", false); //prevent from opening a file

cap.setCapability(FirefoxDriver.PROFILE, fprofile);
WebDriver driver=new FirefoxDriver(cap);

Answer 2

我得到了下面的代码工作：

System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
String downloadFilepath = "/path/to/download";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromeOptionsMap = new HashMap<String, Object>();
options.setExperimentalOptions("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);
WebDriver driver = new ChromeDriver(cap);

Answer 3

ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_settings.popups", 0);
prefs.put("download.default_directory", getClass().getResource("/data/input").toString().replace("%20", " ").replace("file:","").replaceFirst("/", ""));
options.setExperimentalOption("prefs", prefs);

options.addArguments("--test-type");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
