在CentOS7

标签： selenium firefox centos7

我正在尝试在CentOS-VM上设置测试环境。

我在Eclipse中运行的Java-maven项目中有以下三个文件：

main.java 

package main;

public class main {

    public static void main(String[] args) {
        StartFirefox fire = new StartFirefox();
        StartChrome chrome = new StartChrome();

        chrome.start();
        fire.start();
    }
}

StartFirefox.java 

package main;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class StartFirefox {

WebDriver fire;

    public StartFirefox() {
        System.setProperty("webdriver.gecko.driver", "src/main/resources/geckodriver/geckodriver");
        System.out.println("debug 1");
        fire = new FirefoxDriver();
        System.out.println("debug 2");
        fire.manage().window().maximize();
    }

    public void start() {
        System.out.println("debug 3");
        fire.get("https://www.google.com/");
        System.out.println("debug 4");
    }
}

StartChrome.java 

package main;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class StartChrome {

    WebDriver chrome;

    public StartChrome() {
        String pathToChromeDriver = "src/main/resources/chromedriver/chromedriver";
        System.setProperty("webdriver.chrome.driver", pathToChromeDriver);
        System.out.println("debug 1");
        chrome = new ChromeDriver();
        System.out.println("debug 2");
    }

    public void start() {
        System.out.println("debug 3");
        chrome.get("https://www.google.com/");
        System.out.println("debug 4");
    }

}

当使用Firefox运行程序时，窗口会打开，但它不会转到我的网址。 相反，我在一段时间后在控制台中得到以下输出（似乎是超时）：

我被困在这里因为我不知道如何解决这个问题。可能是什么原因？

使用Chrome运行程序时，窗口会打开，但它不会转到我的网址。 相反，我在控制台中得到以下输出：

在Windows 10上运行此项目时，一切正常。

所以这似乎是操作系统的一个问题。但我在搜索时找不到任何解决方案。它只是说服务器和无头版本。

更新：

添加了调试消息。 Firefox只会显示消息1，而Chrome会打印到消息3。

1 个答案:

答案 0 :(得分：0)

来自geckodriver 0.19.1的第一个错误堆栈跟踪确实给了我们一些提示：

  

org.openqa.selenium.WebDriverException：连接被拒绝

但ChromeDriver的第二个堆栈跟踪（v2.9.248304）说明了一切：

  

org.openqa.selenium.WebDriverException：org.apache.http.conn.HttpHostConnectException：连接到localhost：8004 [localhost / 127.0.0.1，localhost / 0：0：0：0：0：0：0：1 ]失败：连接被拒绝（连接被拒绝）

/ etc / hosts文件中的条目未正确配置。

要解决此问题，请确保Linux Box上的/etc/hosts包含以下条目：

127.0.0.1               localhost.localdomain localhost
