问题描述

自1周以来，我一直面临上述问题.早些时候，它运行顺利.即使是现在，有时它仍然可以正常工作，但是在大多数情况下，我会收到"无法连接到本地主机/"错误. :( 我已经将chrome驱动程序升级到2.37，现在再次将其降级到2.36，但是没有运气. :(谢谢.

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)
通过 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.
