我試着將HTMLUnit自動從Web應用下載數據。然而，我在getPage（）上得到了一大堆警告，實際上我不知道發生了什麼，任何人都可以幫助我？HTMLUnit：很多錯誤
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.ScriptResult;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
public class TwitterBot {
public static void main(String[] args){
try{
WebClient webClient = new WebClient(BrowserVersion.FIREFOX_38);
HtmlPage page1 = (HtmlPage) webClient.getPage("https://twitter.com");
HtmlForm form = page1.getFormByName("loginform");
form.getInputByName("Phone, email or username").setValueAttribute(#####);
form.getInputByName("Password").setValueAttribute(#####);
page1 = (HtmlPage) form.getInputByValue("Log In").click();
System.out.println(page1.getTitleText());
}
catch (Exception e) {
// TODO: handle exception
}
}
}

您可以忽略這些警告，因爲有些JavaScript框架有時會使用無效的CSS選擇器進行測試。 HtmlUnit記錄這些錯誤。請指定您是否有問題從頁面獲取所需內容。 –
