ChromeDriver(功能功能)已弃用

Question

我用ChromeDriver 2.33用WebDriver 3.6.0,并尝试设置默认目录文件下载.

Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("download.default_directory", Vars.DOWNLOAD_FOLDER_ROOT);
DesiredCapabilities caps = DesiredCapabilities.chrome();

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
options.setExperimentalOption("prefs", prefs);
caps.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(caps);

我在docs中找到了这个:

请改用ChromeDriver(ChromeOptions).创建一个新的ChromeDriver实例.这些功能将传递给chromedriver服务.

我希望你想问一下解决方法,以避免弃用.

刚建立的旧方法Capabilities已弃用.现在,它需要一个ChromeDriverService&Capabilities作为参数.因此,只需构建一个ChromeDriverService并将其与您一起传递Capabilities以删除弃用警告.

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

ChromeDriverService service = new ChromeDriverService.Builder()
                    .usingDriverExecutable(new File("/usr/local/chromedriver"))
                    .usingAnyFreePort()
                    .build();
ChromeDriver driver = new ChromeDriver(service, capabilities);

编辑: 既然ChromeDriver(service, capabilities)现在也弃用了,你可以使用,

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

ChromeDriverService service = new ChromeDriverService.Builder()
                            .usingDriverExecutable(new File("/usr/local/chromedriver"))
                            .usingAnyFreePort()
                            .build();
ChromeOptions options = new ChromeOptions();
options.merge(capabilities);    
ChromeDriver driver = new ChromeDriver(service, options);

但是,您可以完全跳过DesiredCapabilities并仅ChromeOptions使用setCapability方法,

ChromeOptions options = new ChromeOptions();
options.setCapability("capability_name", "capability_value");
driver = new ChromeDriver(options);
