Question

我正在构建一个工作流程，用户可以在发送查询后获得结果。在这种情况下，用户将发送肽序列，然后它将显示结果。它适用于FireFox驱动程序，但当我尝试使用PhantomJS测试无头浏览器时，它会抛出错误。硒版：2.53.1 PhantomJS版本：2.1.1

Java代码：

package phantomjs;

import java.io.IOException;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.w3c.dom.DOMException;
public class ExtractData {
    public static void main(String[] args) throws InterruptedException, DOMException, IOException {
        String userpepseq="NLAVSQVVHK";
        WebDriver drivermassive = new PhantomJSDriver();
        drivermassive.get("http://exmaple.com/xyz_search.jsp");
        System.out.println(drivermassive.getTitle());
        WebElement searchdatapeptideseq=drivermassive.findElement(By.name("peptide"));
        System.out.println(searchdatapeptideseq.isDisplayed());
        searchdatapeptideseq.sendKeys(userpepseq);
        WebElement datasetbutton=drivermassive.findElement(By.xpath("//button[@class='proxi-selector' and contains (@onclick,'datasets')]"));
        datasetbutton.click();
        System.out.println(datasetbutton.isDisplayed());
        System.out.println(drivermassive.getCurrentUrl());
        Thread.sleep(5000);
        String sCellValuemassid = drivermassive.findElement(By.xpath(".//*[@class='result']/tbody")).getText();
        System.out.println(sCellValuemassid);
        drivermassive.quit();
    }
}

错误：

我想弄清楚为什么它会抛出错误而不是显示结果但是没有运气。任何人都知道如何解决这个问题？

这是因为phantomjs在其javascript引擎中没有polyfill（Function.prototype.bind）函数。现在它（从2.1开始）。尝试下载latest phantomjs release。
