我从 1 周开始就面临上述问题.早些时候它工作顺利.即使现在有时它也可以正常工作，但大多数时候我都会收到无法连接到 localhost/"错误.:(我已将 chrome 驱动程序升级到 2.37，现在又将其降级到 2.36，但没有运气.:( 谢谢.

I am facing above mentioned issue since 1 week. Earlier it was working smoothly. Even now sometimes it works fine but most of the time I am getting "Failed to connect to localhost/" error. :( I have upgraded chrome driver to 2.37 now downgraded it again to 2.36 but no luck. :( Thanks.

问题详情:java.net.ConnectException: 无法连接到 localhost/0:0:0:0:0:0:0:1:4321构建信息:版本:'3.11.0'，修订:'e59cfb3'，时间:'2018-03-11T20:33:15.31Z'系统信息:主机:'GURWUNknjk'，ip:'10.202.126.154'，os.name:'Windows 8.1'，os.arch:'amd64'，os.version:'6.3'，java.version:'1.8.0_131'驱动信息:driver.version:RemoteWebDriver

以下代码供您参考:注意:在登录之前它工作正常.只有当我在登录后尝试搜索某些元素时才会出现问题.

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(); }

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

错误清楚地表明 ChromeDriver 未被识别为:

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

Driver info: driver.version: RemoteWebDriver

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

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

您正在使用 chromedriver=2.37
我们不知道您的 chrome 版本.
您的 Selenium 客户端 版本是 3.11.0.
您的 JDK 版本是 1.8.0_131，相当古老.

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.

所以 JDK v8u131 、Selenium Client v3.11.0 、ChromeDriver 版本之间存在明显的不匹配(v2.37).

So there is a clear mismatch between the JDK v8u131 , Selenium Client v3.11.0 , ChromeDriver version (v2.37).

将 JDK 升级到最新级别 JDK 8u162.
将 ChromeDriver 保留在当前 ChromeDriverv2.37 级别.
将 Chrome 版本保持在 Chrome v65.x 级别.(根据 ChromeDriver v2.37 发行说明)
清理你的项目工作区通过你的IDE和重建你的项目只需要依赖.
使用 CCleaner 工具清除之前和在您的测试套件执行之后.
如果您的基础 Web Client 版本太旧，请通过卸载它Revo Uninstaller 并安装最新的 GA 和发布版本的 Web Client.
进行一次系统重启.
执行你的 @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.
