如何通过 Selenium Java 初始化 PhantomJS 浏览器

How to initialize PhantomJS browser through Selenium Java(如何通过 Selenium Java 初始化 PhantomJS 浏览器)

问题描述

我正在尝试使用 Java 中的 phantomjsdriver 来构建 Webspider.我正在使用 Selenium 版本 3.11.0、PhantomJS 2.1.1 和 phantomjsdriver 版本 1.2.1.当我执行我的代码时，我收到以下错误消息.

I am trying to use the phantomjsdriver in Java to build a Webspider. I am using Selenium Version 3.11.0, PhantomJS 2.1.1 and the phantomjsdriver Version 1.2.1. When i am executing my code I get the following error Message.

线程main"中的异常 java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String;

Exception in thread "main" java.lang.NoSuchMethodError: org.openqa.selenium.os.CommandLine.find(Ljava/lang/String;)Ljava/lang/String;

package Masterarbeit.Crawler;
import java.io.File;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;

public class Test {

    public String Test(){
        File path=new File("/usr/local/bin/phantomjs");
        System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
        WebDriver driver = new PhantomJSDriver(); 
        return "successful";

    }
}

我的操作系统是 Linux Mint 18 Sarah，有人知道原因吗?

推荐答案

几天前 PhantomJSDriver 与 selenium-server-standalone-vvvjar 一起发布所以我们能够通过 selenium 中的 import org.openqa.selenium.phantomjs.PhantomJSDriver; 解决方法 PhantomJSDriver()-server-standalone-xyzjar

Till a few days back PhantomJSDriver was released bundled along with selenium-server-standalone-v.v.v.jar so we were able to resolve the method PhantomJSDriver() through import org.openqa.selenium.phantomjs.PhantomJSDriver; from the selenium-server-standalone-x.y.z.jar

但现在，selenium-server-standalone-v.v.v.jar 不会为 PhantomJSDriver 依赖项捆绑 jar.因此，您必须从 (com.codeborne:phantomjsdriver:jar:1.4.4) 获取似乎与最新的 selenium 版本保持同步的 phantomjsdriver 版本.

But now, selenium-server-standalone-v.v.v.jar doesn't bundles the jar for PhantomJSDriver dependency. So you have to obtain a version of phantomjsdriver from (com.codeborne:phantomjsdriver:jar:1.4.4) that appears to be kept up to date with latest selenium releases.

下载 phantomjsdriver-1.4.4.jar 并将其添加到您的项目.

Download and add the phantomjsdriver-1.4.4.jar to your Project.

使用以下代码块并执行您的 @Test :

Use the following code block and execute your @Test :

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;

public class phantomJS_launch {

    public static void main(String[] args) {


          File path=new File("C:\Utility\phantomjs-2.1.1-windows\bin\phantomjs.exe");
          System.setProperty("phantomjs.binary.path",path.getAbsolutePath());
          WebDriver driver= new PhantomJSDriver();
          driver.get("https://www.google.co.in");
          System.out.println(driver.getTitle());
          driver.quit();

    }

}

重要:PhantomJSDriver()仍然通过import org.openqa.selenium.phantomjs.PhantomJSDriver解析；
