以下是代码供您参考:注意:在登录之前可以正常工作.只有在登录后尝试搜索某些元素时，问题才会出现.

Here is code for your reference:Note : It works fine till login. Issue comes only when I try to search some element after login.

    public static WebDriver driver;
    public static void main(String[] args) throws InterruptedException, IOException {
                System.setProperty("webdriver.chrome.driver", "d://chromedriver.exe");
        driver = new ChromeDriver();
        String url = "https://accounts.google.com/signin/v2/identifier?continue=https%3A%2F%2Faccounts.google.com%2Fb%2F0%2FAddMailService&flowName=GlifWebSignIn&flowEntry=AddSession";
        driver.get(url);

driver.manage().window().maximize();
        WebDriverWait wait = new WebDriverWait(driver, 20);
        driver.manage().timeouts().implicitlyWait(15,TimeUnit.SECONDS) ;

        wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("input[type='Email']")));

        if(driver.getCurrentUrl().contains("https://accounts.google.com/signin/v2/identifier?"))
        {

            driver.findElement(By.id("identifierId")).sendKeys(username);
            driver.findElement(By.id("identifierNext")).click();        wait.until(ExpectedConditions.presenceOfElementLocated(By.name("password")));
            driver.findElement(By.name("password")).sendKeys(pwd);
            driver.findElement(By.name("password")).sendKeys(Keys.ENTER);
        }
        else{
            wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("input[type='Email']")));
            driver.findElement(By.name("Email")).sendKeys(UserName);
            driver.findElement(By.id("next")).click();           wait.until(ExpectedConditions.presenceOfElementLocated(By.name("Passwd")));
            driver.findElement(By.name("Passwd")).sendKeys(Pwd);
                    wait.until(ExpectedConditions.presenceOfElementLocated(By.name("signIn")));
 driver.findElement(By.id("signIn")).click();
           }
wait.until(ExpectedConditions
                    .visibilityOfElementLocated(By.id(element id)));
            driver.findElement(By.id(element id))
            .sendKeys(some value);
            Thread.sleep(3000);
            driver.findElement(By.id(element id)).click(); }

推荐答案

错误说明了一切:

java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:4321
Build info: version: '3.11.0', revision: 'e59cfb3', time: '2018-03-11T20:33:15.31Z'
System info: host: 'GURWUNknjk', ip: '10.202.126.154', os.name: 'Windows 8.1', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_131'
Driver info: driver.version: RemoteWebDriver

该错误清楚地表明 ChromeDriver 无法识别为:

The error clearly shows that the ChromeDriver was not recognized as in :

Driver info: driver.version: RemoteWebDriver

您的主要问题是所使用的二进制文件之间的版本兼容性:

Your main issue is the version compatibility between the binaries you are using as follows :

您正在使用 chromedriver = 2.37
您不知道您的 chrome 版本.
您的 Selenium Client 版本是 3.11.0 .
您的 JDK版本是 1.8.0_131 ，这很古老.

You are using chromedriver=2.37
Your chrome version is unknown to us.
Your Selenium Client version is 3.11.0.
Your JDK version is 1.8.0_131 which is pretty ancient.

因此 JDK v8u131 ， Selenium Client v3.11.0 和 ChromeDriver 版本( v2.37 ).

将 JDK 升级到最新级别 JDK 8u162 .
在当前ChromeDriver "rel =" nofollow noreferrer> ChromeDriver v2.37 级别.
保持 Chrome 版本处于 Chrome v65.x 级别. (根据ChromeDriver v2.37发行说明)

IDE

清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
使用 CCleaner 工具清除之前和之后的所有操作系统杂项在执行 test Suite 之后.
如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
进行系统重启.
执行您的@Test.

Upgrade JDK to recent levels JDK 8u162.
Keep ChromeDriver at current ChromeDriver v2.37 level.
Keep Chrome version at Chrome v65.x levels. (as per ChromeDriver v2.37 release notes)
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your @Test.
