推荐答案

为了快速便携地进行操作，您可以查看服务器提供的页面。

To do it quickly and portably, you can check for a page if it's served by the server.

例如你可以：

boolean isAlive = true;
try {
  URL hp = new URL("http://yourserver/TestPage.html"); 
  URLConnection hpCon = hp.openConnection(); 
  // add more checks...
} catch (Exception e) {
  isAlive = false;
}

这种不太复杂的方法适用于每个http服务器。

This not much sophisticated method will work with every http server.
