java - 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，我收到以下错误消息。

线程“main”中出现异常 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，有人知道其中的原因吗？

直到几天前，PhantomJSDriver 与 selenium-server-standalone-v.v.v.jar 捆绑在一起发布，因此我们能够解析该方法 PhantomJSDriver() 通过 import org.openqa.selenium.phantomjs.PhantomJSDriver; 从 selenium-server-standalone-x.y.z.jar

但是现在，selenium-server-standalone-v.v.v.jar 不捆绑 PhantomJSDriver 依赖项的 jar。因此，您必须从 (com.codeborne:phantomjsdriver:jar:1.4.4) 获取 phantomjsdriver 版本，该版本似乎与最新的 selenium 版本保持同步。

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

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;<解析
