http基本get和post请求

get请求：

    private static void httpGet(){
        BufferedReader br = null;
        HttpURLConnection conn = null;
        try {
            String strUrl = "http://agneshome.www.leyingtt.com/agnes_home/config/query";
            URL url = new URL(strUrl);
            conn = (HttpURLConnection)url.openConnection();
            conn.setDoInput(true);
            conn.setDoOutput(true);
            conn.setConnectTimeout(10000);
            conn.connect();

            br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line = null;
            StringBuilder sb = new StringBuilder();
            while(true){
                line = br.readLine();
                if(line == null){
                    break;
                }
                sb.append(line).append("
");
            }
            if(sb.length() > 0){
                sb.setLength(sb.length()-1);
            }
            Log.i(MainActivity.TAG, sb.toString());

        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            try{
                if(br != null){
                    br.close();
                }
                if(conn != null){
                    conn.disconnect();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

post请求：

    private static void httpPost(){
        BufferedReader br = null;
        HttpURLConnection conn = null;
        try {
            String strUrl = "https://www.baidu.com";
            URL url = new URL(strUrl);
            conn = (HttpURLConnection)url.openConnection();
            conn.setDoInput(true);
            conn.setDoOutput(true);
            conn.setConnectTimeout(5000);
            conn.setRequestMethod("POST");
            conn.connect();

            br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line = null;
            StringBuilder sb = new StringBuilder();
            while(true){
                line = br.readLine();
                if(line == null){
                    break;
                }
                sb.append(line).append("
");
            }
            if(sb.length() > 0){
                sb.setLength(sb.length()-1);
            }
            Log.i(MainActivity.TAG, sb.toString());

        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            try{
                if(br != null){
                    br.close();
                }
                if(conn != null){
                    conn.disconnect();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
