如何解决“不推荐使用构造函数 ChromeDriver(Capabilities)"和 WebDriverException:ChromeDriver 和 Chrome 出现超时错误 [英] How to address "The constructor ChromeDriver(Capabilities) is deprecated" and WebDriverException: Timed out error with ChromeDriver and Chrome

问题描述

我正在尝试如下配置默认下载目录，它可以正常工作，但我遇到了两个问题:

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. 它告诉我 构造函数 ChromeDriver(Capabilities) 是已弃用

2. 当我多次重播测试时，它恰好有一个 Webdrive TimeOut 异常

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

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

推荐答案

看来你快到了.您需要使用方法 merge() 来自 MutableCapabilities 类将DesiredCapabilities类型的对象合并到ChromeOptions 类型对象并通过传递 ChromeOptions 对象来启动 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);
