App 实现的两类网络请求

1.Java HttpUrl 的实现如下：

1.1 Get 请求

{
       //显示进度
        final  ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("正在获取数据请稍后！");
        progressDialog.show();

        //启动分线程
        new Thread(){
            @Override
            public void run() {
                String strPath = et_network_url.getText().toString();
                 URL  url =null;

                HttpURLConnection httpURLConnection = null;
                try {
                    url = new URL(strPath);
                    httpURLConnection = (HttpURLConnection) url.openConnection();
                    httpURLConnection.setRequestMethod("GET");
                    httpURLConnection.setConnectTimeout(5000);
                    httpURLConnection.setReadTimeout(5000);
                    httpURLConnection.connect();
                    int Recode = httpURLConnection.getResponseCode();
                    if(Recode==200){
                        InputStream is =  httpURLConnection.getInputStream();
                        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
                        byte[] buffer = new byte[]{};
                        int len =-1;
                        while ((len=is.read(buffer))!=-1){
                            byteArrayOutputStream.write(buffer,0,len);
                        }
                        final  String result = byteArrayOutputStream.toString();
                        is.close();
                        byteArrayOutputStream.close();
                    }
                    httpURLConnection.connect();
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            //et_network_result.setText(result);
                            progressDialog.dismiss();
                        }
                    });

                } catch (Exception e) {
                    e.printStackTrace();
                }finally {
                    progressDialog.dismiss();
                }
            }
        }.start();
    }

1.2 Post 请求

{

        final  ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("正在获取数据请稍后！");
        progressDialog.show();
        new Thread(new Runnable() {
            @Override
            public void run() {
                String strPath = et_network_url.getText().toString();
                URL  url =null;

                HttpURLConnection httpURLConnection = null;
                try {
                    url = new URL(strPath);
                    httpURLConnection = (HttpURLConnection) url.openConnection();
                    httpURLConnection.setRequestMethod("GET");
                    httpURLConnection.setConnectTimeout(5000);
                    httpURLConnection.setReadTimeout(5000);
                    httpURLConnection.connect();
                    OutputStream os = httpURLConnection.getOutputStream();
                    String data = "name=Tom&age=11";
                    os.write(data.getBytes("utf-8"));
                    //成功
                    if(httpURLConnection.getResponseCode()==200){
                        InputStream is =  httpURLConnection.getInputStream();
                        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
                        byte[] buffer = new byte[]{};
                        int len =-1;
                        while ((len=is.read(buffer))!=-1){
                            byteArrayOutputStream.write(buffer,0,len);
                        }
                        final  String result = byteArrayOutputStream.toString();
                        is.close();
                        byteArrayOutputStream.close();
                    }
                    os.close();
                    httpURLConnection.connect();

                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            //et_network_result.setText(result);
                            progressDialog.dismiss();
                        }
                    });

                }catch (Exception ex){

                }finally {
                    progressDialog.dismiss();
                }

            }
        }).start();
    }

2.Volley 框架实现：

2.1 Get 请求

//创建请求对象
        final  ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("正在获取数据请稍后！");
        progressDialog.show();
        String strPath = et_network_url.getText().toString();
        StringRequest stringRequest = new StringRequest(strPath, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) { //主线程执行
                et_network_result.setText(response);
                progressDialog.dismiss();
            }
        }, new Response.ErrorListener() {
            @Override
            public void one rrorResponse(VolleyError error) {
                progressDialog.dismiss();
            }
        });
        requestQueue.add(stringRequest);

2.2 Post 请求

//创建请求对象
        final  ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setTitle("正在获取数据请稍后！");
        progressDialog.show();
        String strPath = et_network_url.getText().toString();
        StringRequest stringRequest = new StringRequest(Request.Method.POST, strPath, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                et_network_result.setText(response);
                progressDialog.dismiss();
            }
        }, new Response.ErrorListener() {
            @Override
            public void one rrorResponse(VolleyError error) {
                progressDialog.dismiss();
            }
        }){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {

                Map<String,String> map = new HashMap<String, String>();
                map.put("name", "Tom6");
                map.put("age", "16");
                return map;
            }
        };
        requestQueue.add(stringRequest);
