网络请求（HttpUrlConnection/HttpClient）

httpurlconnection

get方式请求

            URL url=new URL(params[0]);
            HttpURLConnection connection=(HttpURLConnection) url.openConnection();
            if(connection.getResponseCode()==200){
                InputStream is=connection.getInputstream();
                //调用自定义的json解析的工具类
                String json=jiesonutils.getjson(is);
                return 
            }

post

    URL url=new URL("https://tcc.taobao.com/cc/json/mobile_tel_segment.htm");
                    HttpURLConnection connection=(HttpURLConnection) url.openConnection();

                    connection.setRequestMethod("POST");
                    //设置参数
                    connection.setDoOutput(true);//是否向服务器写参数
                    StringBuffer sb=new StringBuffer();
                    sb.append("tel=").append(et.getText().toString());
                    //写参数，写字节数组（吧参数内容转为字节数组）
                    byte[] be=sb.toString().getBytes();
                    connection.getOutputStream().write(be);

                    if(connection.getResponseCode()==200){

HttpClient

get

//客户端请求
            HttpClient client=new DefaultHttpClient();
            //请求方式
            HttpGet get=new HttpGet(params[0]);
            //执行get请求，获得相应数据
            HttpResponse response=client.execute(get);
            if(response.getStatusLine().getStatusCode()==200){
                InputStream is=response.getEntity().getContent();
                //tojsonutils自定义的解析json的工具类
                return tojsonutils.getjson(is);
            }

Post
