HTMLUnit EcmaError TypeError

时间：2017-06-03 23:11:56

标签： java htmlunit

我试图从网址＆＃34; https://www.mtgstocks.com/lists/1＆＃34;中获取数据。通过HTMLUnit，我收到了这个错误，我不知道从哪里开始。我甚至不理解错误的含义。

首先这是我的代码：

import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import java.io.IOException;

public class Main {
public static void main(String[] args) throws Exception {
    java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF);
    try {

        WebClient webClient = new WebClient(BrowserVersion.CHROME);
        HtmlPage page = webClient.getPage("https://www.mtgstocks.com/lists/1");
        webClient.getOptions().setJavaScriptEnabled(true);
        //webClient.waitForBackgroundJavaScript(3000);
    } catch (IOException ex) {
        ex.printStackTrace();
        }
    }
}

这是我的错误：
