如何通过Selenium Java初始化phantomjs浏览器

Question

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。当我执行代码时，我会收到以下错误消息。

线程" main" java.lang.nosuchmethoderror中的例外：org.openqa.selenium.os.commandline.find(ljava/lang/lang/string;(ljava/lang/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，有人知道这样的原因吗？

Answer 1

直到几天前 phantomjsdriver 与 selenium-server-server-standalone-v.v.v.v.v.v.v.v.v.v.v.jar 释放，所以我们能够解决方法 PhantomJSDriver() 通过 import org.openqa.selenium.phantomjs.PhantomJSDriver;从 selenium-server-standalone-x.y.z.jar

但现在， selenium-server-standalone-v.v.v.v.jar 不会将jar捆绑在 phantomjsdriver 依赖项中。因此，您必须从(com.codeborne:phantomjsdriver:jar:1.4.4(获得 phantomjsdriver 的版本，该版本似乎与最新的硒版本保持最新。

下载并添加 phantomjsdriver-1.4.4.4.4.4.jar 到您的 project 。

使用以下代码块并执行您的@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;

解决
