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.

public class Test {
public String Test(){

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；
