Okhttp获取数据+Volley获取数据与图片

Okhttp获取数据代码：

//okhttp的GET的访问
    public void Okhttp_GET(String urlStr){
        Request request = new Request.Builder().url(urlStr).get().build();
        OkHttpClient client = new OkHttpClient();
        try {
            Response response = client.newCall(request).execute();
            if(response.isSuccessful()){
                String json = response.body().string();
                Log.e("###",json);
            }else{
                Log.e("###","对不起请求失败！！！");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    //Okhttp_POST访问方式
    public void  Okhttp_POST(String urlStr){
        FormBody body = new FormBody.Builder()
                .add("phone","13722655422")
                .add("passwd","124")
                .build();
        Request request = new Request.Builder().url(urlStr).post(body).build();
        OkHttpClient client = new OkHttpClient();
        try {
            Response response = client.newCall(request).execute();
            if(response.isSuccessful()){
                Log.e("###",response.body().string());
            }else{
                Log.e("###","请求失败！！！");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    /**
     * okhttp的异步加载
     */
    public void AsyncGET(String urlStr){
        Request request = new Request.Builder().url(urlStr).get().build();
        OkHttpClient client = new OkHttpClient();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.e("###","请求失败");
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                Log.e("###",response.body().string());
            }
        });
    }
    //异步加载的POST请求
    public void AsyncPOST(String urlStr){
        FormBody body = new FormBody.Builder()
                .add("phone","983487889")
                .add("passwd","123")
                .build();
        Request request = new Request.Builder().url(urlStr).post(body).build();
        OkHttpClient client = new OkHttpClient();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.e("###","请求失败！！！");
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                Log.e("###",response.body().string());
            }
        });
    }

Volley获取数据代码：

/**
     * volley加载图片和字符串
     */
    public void VolleyGet(String strUrl, Context context){
        RequestQueue queue = Volley.newRequestQueue(context);
        StringRequest request = new StringRequest(StringRequest.Method.GET, strUrl, listener, errorListener);
        queue.add(request);//将请求添加到队列
        queue.start();//启动队列
    }
    com.android.volley.Response.Listener<String> listener = new com.android.volley.Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.e("###成功",response);
        }
    };
    com.android.volley.Response.ErrorListener errorListener = new com.android.volley.Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("###","请求失败！！！");
        }
    };

    public void VolleyPost(String urlStr,Context context){
        RequestQueue queue = Volley.newRequestQueue(context);
        StringRequest request = new StringRequest(StringRequest.Method.POST,urlStr,listener,errorListener){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                HashMap<String,String> map = new HashMap<>();
                map.put("phone","1286041884");
                map.put("passwd","123");
                return map;
            }
        };
        queue.add(request);//添加入队列
        queue.start();//启动队列
    }
    public void Volley_Image(String urlStr, final ImageView imageView, Context context){
        ImageRequest imageRequest = new ImageRequest(urlStr, new com.android.volley.Response.Listener<Bitmap>() {
            @Override
            public void onResponse(Bitmap response) {
                imageView.setImageBitmap(response);
            }
        }, 100, 100, Bitmap.Config.ARGB_8888, errorListener);
        RequestQueue queue = Volley.newRequestQueue(context);
        queue.add(imageRequest);
        queue.start();
    }
