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;
    }
