我一直在开发一个应用程序，它可以解析三个网站页面的信息，然后将解析后的信息显示给用户。自从这工作以来，我在过去的几周里从来没有遇到过任何例外。然后今天当我再次测试解析功能时，我没有得到任何结果，并且 logcat 给出了 SSLHandshakeException 以及一堆系统错误。以下错误来自 logcat：

下面是负责解析网页的我的 QueryActivity 的部分代码。我将三个网站的 url 从另一个活动传递到 QueryActivity 然后我使用 Jsoup 连接并获取用于解析的 html。
public class QueryActivity extends Activity
{
String fWebsite = getIntent().getStringExtra("fURL");
String sWebsite = getIntent().getStringExtra("sURL");
String tWebsite = getIntent().getStringExtra("tURL");
try{
Document doc1 = Jsoup.connect(fWebsite).timeout(0).get();
Document doc2 = Jsoup.connect(sWebsite).timeout(0).get();
Document doc3 = Jsoup.connect(tWebsite).timeout(0).get();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
有人可以解释为什么会发生这种情况以及此问题的任何解决方案吗？据我所知，我没有更改此活动（QueryActivity）中的任何代码？谢谢你。
