URL theURL = new URL(url);
URLConnection urlConn = theURL.openConnection();
urlConn.setDoOutput(true);
BufferedReader urlReader = new BufferedReader(newInputStreamReader(urlConn.getInputStream()));

…然后开始循环阅读内容…

do
    {
    buf = urlReader.readLine();
    if (buf != null)
        {
        resultBuffer.append(buf);
        resultBuffer.append("\n");
        }
    }
while (buf != null);

…但是如果读取挂起,则应用程序挂起.

有没有办法,没有磨削代码到套接字级别,如果需要,“超时”读取？
