HtmlUnit Java 按钮单击警告

Question

我尝试编写一个可以登录到我的 mlg 帐户的程序。我正在使用 HtmlUnit。这是我的代码：

import java.net.*;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.*;
import java.io.IOException;
import org.apache.commons.logging.LogFactory;


public class test {


        public static void main(String... args) throws FailingHttpStatusCodeException, MalformedURLException, IOException{

            //supress first warnings
            java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(java.util.logging.Level.OFF);
            java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);
            LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");

            WebClient webClient = new WebClient(BrowserVersion.CHROME);
            webClient.getOptions().setJavaScriptEnabled(true);
            webClient.getOptions().setThrowExceptionOnScriptError(false);

            HtmlPage page = webClient.getPage("https://accounts.majorleaguegaming.com/");

            HtmlForm form = page.getForms().get(0);

            System.out.println(page.getTitleText());
            //Edited my username & Password
            form.getInputByName("login").setValueAttribute("MYUSERNAME");
            form.getInputByName("password").setValueAttribute("MYPASSWORD");

            HtmlElement button = form.getInputByName("commit");

            page = button.click();

            System.out.println("AFTER CLICK");
            System.out.println(page.getTitleText());
            System.out.println(page.asText());

    }
}

我测试了代码，它运行得很好，但是我收到了这些警告，这让程序很慢：

我确定那行

page = button.click();

是警告的原因。谁能帮我？我应该使用 HtmlUnit 以外的任何东西吗？或者有谁知道如何抑制警告？

谢谢:)

它们似乎只是 JS 警告。很可能是因为 JS 引擎不喜欢代码的某些部分。如果流程正常，请忽略它们。

如果您想关闭它们，他们很可能会放弃我对这个问题的回答（您只需添加 2 行）：Turning HtmlUnit Warnings off
