Próbuję HTMLUnit, aby zautomatyzować pobieranie danych z aplikacji internetowej. Jednak otrzymuję cały bałagan ostrzeżeń na getPage() (większość z nich wydaje się zajmować połączonymi skryptami, których nie potrzebuję nawet potrzebować), a następnie fatalny com.gargoylesoftware.htmlunit.ScriptException: Wyjątek wywołujący setOuterHTML, gdy Próbuję uruchomić getByXPath, aby pobrać dane, których szukam. I z powodu błędów, które dostaję, nie mogę do końca zrozumieć, co się dzieje. Masz jakieś pomysły?HTMLUnit: Mnóstwo przestarzałej treści i nie można tworzyć ostrzeżeń obiektów na getPage(), a następnie kończy się niepowodzeniem z wywołaniem wyjątku setOuterHTML na getByXPath()

Oto mój kod:

import java.util.List; 

import com.gargoylesoftware.htmlunit.WebClient; 
import com.gargoylesoftware.htmlunit.BrowserVersion; 
import com.gargoylesoftware.htmlunit.html.HtmlAnchor; 
import com.gargoylesoftware.htmlunit.html.HtmlPage; 

public class ScrapperApp { 

    private static void go() throws Exception { 
     HtmlPage nextPage; 
     String url = "http://media.ethics.ga.gov/search/Campaign/Campaign_Name.aspx?NameID=5751&FilerID=C2009000085&Type=candidate"; 

     final WebClient webclient = new WebClient(); 
     final HtmlPage page = webclient.getPage(url); 

     System.out.println("PULLING LINKS:"); 

     List<HtmlAnchor> articles = (List<HtmlAnchor>) page.getByXPath("//div[@class='hform1']/a[@class='lblentrylink']"); 

     /*for(int x=0; x<articles.size(); x++) { 
      nextPage = articles.get(x).click(); 
      System.out.println(nextPage.getBody()); 
     }*/ 
    } 

    public static void main(String[] args) throws Exception { 
     go(); 
     System.out.println("COMPLETE"); 
    } 

}

i tu jest moje wyjście konsoli:

Błąd pochodzi z pliku MicrosoftAjax.js. Spróbuj symulować chrom:

final WebClient webclient = new WebClient(BrowserVersion.CHROME);

Dodano również link do tłumienia ostrzeżeń HtmlUnit.

Twój XPath również niczego nie znajduje (testowałem w Chrome). Użyłem innego na przykład:

import java.util.List; 

import com.gargoylesoftware.htmlunit.WebClient; 
import com.gargoylesoftware.htmlunit.BrowserVersion; 
import com.gargoylesoftware.htmlunit.html.HtmlAnchor; 
import com.gargoylesoftware.htmlunit.html.HtmlPage; 

public class ScrapperApp { 

    private static void go() throws Exception { 
     /* turn off annoying htmlunit warnings */ 
     java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF); 

     HtmlPage nextPage; 
     String url = "http://media.ethics.ga.gov/search/Campaign/Campaign_Name.aspx?NameID=5751&FilerID=C2009000085&Type=candidate"; 

     final WebClient webclient = new WebClient(BrowserVersion.CHROME); 
     final HtmlPage page = webclient.getPage(url); 

     System.out.println("PULLING LINKS:"); 

     List<HtmlAnchor> articles = (List<HtmlAnchor>) page.getByXPath("//a[@class='lblentrylink']"); 
     //List<HtmlAnchor> articles = (List<HtmlAnchor>) page.getByXPath("//div[@class='hform1']/a[@class='lblentrylink']"); 

     for(int x=0; x<articles.size(); x++) { 
      System.out.println("Clicking "+articles.get(x).asText()); 
      //nextPage = articles.get(x).click(); 
      //System.out.println(nextPage.getBody()); 
     } 
    } 
    public static void main(String[] args) throws Exception { 
     go(); 
     System.out.println("COMPLETE"); 
    } 
}
