Question

我是 Selenium 的新手，当运行我的代码时，我遇到了关于 CDP 版本的错误。这是我的代码。很简单，旨在登录某个网页。 driver 打开，填写电子邮件和密码，但是当到达按钮时，driver 关闭。即使我设置了另一个等待十分钟后的按钮。

    public static void main(String[] args) {
            System.setProperty("webdriver.chrome.driver","path/to/my/chromedriver");
            WebDriver driver = new ChromeDriver();
            WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
            try {
                driver.get("https://someweb.com/");
                driver.findElement(By.name("Email")).sendKeys("anemail@email.com");
                driver.findElement(By.name("Password")).sendKeys("randomPass");
                driver.findElement(By.xpath("//*[@id=\"login-form\"]/button")).sendKeys(Keys.ENTER);
            } finally {
                driver.quit();
            }

        }

我在日志中收到以下警告

我的 pom 中有以下依赖项

    <dependencies>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>

我不知道为什么 driver 突然退出。 Chrome 和 ChromeDriver 版本是 94.0.4606.61。提前致谢！

根据 Selenium 文档，

版本 v4.0.0-rc-1 支持 CDP 版本: 85, 92, 93.

但是您使用的是 Chrome 和 ChromeDriver 的 94 版本。所以请将您的依赖项更新到最新版本 v4.0.0-rc-2

依赖关系:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>4.0.0-rc-2</version>
</dependency>

参考：https://github.com/SeleniumHQ/selenium/blob/trunk/java/CHANGELOG

Java - Selenium - 无法找到与 CDP 版本 94 完全匹配的版本，因此返回找到的最接近的版本：93
