如何解决“不赞成使用构造函数ChromeDriver(Capabilities)"的问题，和WebDriverException:ChromeDriver和Chrome超时错误

问题描述

我正在尝试如下配置默认的下载目录，它可以正常工作，但是有两个问题:

I'm trying to config the default download directory as below, it's works correctly but I'm having two issues :

    String exePath = "src\\Drivers\\chromedriver.exe";
    System.setProperty("webdriver.chrome.driver", exePath);
    String downloadFilepath = "U:\\Data\\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();
    options.setExperimentalOption("prefs", chromePrefs);
    DesiredCapabilities cap = DesiredCapabilities.chrome();
    cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    cap.setCapability(ChromeOptions.CAPABILITY, options);
    driver = new ChromeDriver(cap);
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

1. 这告诉我构造函数ChromeDriver(Capabilities)是不推荐使用

2. 当我重复测试几次时，碰巧有一个Webdrive超时异常

1. It's telling me that The constructor ChromeDriver(Capabilities) isdeprecated

2. When I replay the test several times it happens to have a Webdrive TimeOut exception

推荐答案

似乎您快到了.您需要使用方法 merge() 来自 MutableCapabilities 类，将对象的 DesiredCapabilities 类型合并到 ChromeOptions 键入对象，并通过传递 ChromeOptions 对象，以启动 WebDriver 和 WebClient 实例，如下所示:

It seems you were almost there. You need to use the method merge() from MutableCapabilities Class to merge the DesiredCapabilities type of object into ChromeOptions type object and initiate the WebDriver and WebClient instance by passing the ChromeOptions object as follows :

String exePath = "src\\Drivers\\chromedriver.exe";
System.setProperty("webdriver.chrome.driver", exePath);
String downloadFilepath = "U:\\Data\\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();
options.setExperimentalOption("prefs", chromePrefs);
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);
options.merge(cap);
driver = new ChromeDriver(options);
