HTMLUnit: Tons of obsolete content and can't create objects warnings on getPage() then fails with Exception invoking setOuterHTML on getByXPath()
提问by Jeff
I'm trying out HTMLUnit to automate downloading data off a webapp. However, I am getting a whole mess of warnings on getPage() (most of which seem to deal with linked scripts that I don't think i even need) and then a fatal com.gargoylesoftware.htmlunit.ScriptException: Exception invoking setOuterHTML when I try and run getByXPath to pull the data I'm looking for. And from the errors I get, I can't for the life of me figure out what's going on. Y'all got any ideas?
我正在尝试使用 HTMLUnit 来自动从 web 应用程序下载数据。但是，我在 getPage() 上收到了一大堆警告（其中大部分似乎处理我认为我什至不需要的链接脚本），然后是致命的 com.gargoylesoftware.htmlunit.ScriptException: Exception invoking setOuterHTML when我尝试运行 getByXPath 来提取我正在寻找的数据。从我得到的错误中，我终生无法弄清楚发生了什么。大家有什么想法吗？
Here's my code:
这是我的代码：
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");
}
}
and here is my console output:
这是我的控制台输出：

The error comes from a MicrosoftAjax.jsfile. Try simulating chrome:
错误来自一个MicrosoftAjax.js文件。尝试模拟铬：
final WebClient webclient = new WebClient(BrowserVersion.CHROME);
Also added a link to suppress HtmlUnit warnings.
还添加了一个链接来抑制 HtmlUnit 警告。
Also, your XPath doesn't find anything (I tested in Chrome). I used another for example purposes:
此外，您的 XPath 没有找到任何东西（我在 Chrome 中测试过）。我使用另一个示例目的：
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");
}
}
