Androidの网络Http之判断是否连接服务器

 

1.采用Http方式：

public boolean isConnByHttp(){boolean isConn = false;URL url;HttpURLConnection conn = null;try {url = new URL("ttp://wl.daishu001.com/YHDriver.asmx");conn = (HttpURLConnection)url.openConnection();conn.setConnectTimeout(1000*5);if(conn.getResponseCode()==200){isConn = true;}} catch (MalformedURLException e) {// TODO Auto-generated catch block
            e.printStackTrace();}catch (IOException e) {// TODO Auto-generated catch block
            e.printStackTrace();}finally{conn.disconnect();}return isConn;}
