java - ChromeDriver(Capabilities 能力) 已弃用

Question

我使用 ChromeDriver 2.33 和 WebDriver 3.6.0 并尝试设置文件下载的默认目录。

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);

我在文档中找到了这个:

Use ChromeDriver(ChromeOptions) instead. Creates a new ChromeDriver instance. The capabilities will be passed to the chromedriver service.

我希望您想询问避免弃用的解决方法。

仅使用 Capabilities 构建的旧方法已被弃用。现在，它采用 ChromeDriverService 和 Capabilities 作为参数。因此，只需构建一个 ChromeDriverService 并将其与您的 Capabilities 一起传递即可删除弃用警告。

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: 由于 ChromeDriver(service, capabilities) 现在也已弃用，您可以使用，

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 并仅使用 ChromeOptions 和 setCapability 方法，例如，

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