javascript - WebClient 无法加载 Twitter 页面

Question

这是我的代码。我尝试使用 Java 中的 WebClient 加载 Twitter 注册页面。

public LoadTwitter() {
    client = new WebClient(BrowserVersion.CHROME);
    client.getOptions().setJavaScriptEnabled(true);
    client.getOptions().setThrowExceptionOnScriptError(false);
    //client.waitForBackgroundJavaScript(2000);
}

public void loadPage() throws IOException {
    HtmlPage page = client.getPage("http://twitter.com/signup");
}

但是我有很多 JavaScript 错误。如果我关闭javascript。我得到的是移动版本而不是网络版本。如何解决这个问题？

Answer 1

试试这个，它应该通过 HtmlUnit 删除日志:

LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");

java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF); 
java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);

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