我試圖從URL「https://www.mtgstocks.com/lists/1」獲取數據。通過HTMLUnit我得到這個錯誤，我不知道從哪裏去。我甚至不明白錯誤的含義。HTMLUnit EcmaError類型錯誤
首先這是我的代碼：
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();
}
}
}
這是我的錯誤：
