okhttp封裝

對這玩意並不熟，網上有不少大神封裝好的，可是懶得看裏面的封裝邏輯，索性本身簡單作個封裝，方便使用，出現bug也好查找：

get請求：

/**
         * get請求
         * @param url
         * @param callback
         */
        public static void requestByGet(String url,Callback callback){
            String baseUrl = "";
            OkHttpClient mOkHttpClient = new OkHttpClient();
            //建立一個Request
            final Request request = new Request.Builder()
                    .url(baseUrl + url)
                    .build();
            mOkHttpClient.newCall(request).enqueue(callback);
        }

post請求：

/**
         * post請求
         * @param url
         * @param map
         * @param callback
         * @throws IOException
         */
        public static void requestByPost(String url ,HashMap<String,Object> map,Callback callback) {
            String baseUrl = "";
            FormEncodingBuilder formEncodingBuilder = new FormEncodingBuilder();

            for(String key:map.keySet()){

                formEncodingBuilder.add(key, map.get(key) + "");
            }
            RequestBody body = formEncodingBuilder.build();

            OkHttpClient client = new OkHttpClient();

            Request request = new Request.Builder()
                    .url(baseUrl+url)
                    .post(body)
                    .build();
            client.newCall(request).enqueue(callback);
        }

使用方法：

   String url="";
        HashMap<String,Object> map=new HashMap<>();
        map.put("userid",userId);//本身的接口參數
        HttpUtils.requestByPost(url, map, new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {
            }
            @Override
            public void onResponse(Response response) throws IOException {
                String data = response.body().string();
                parseData(data);//解析json串，方法根據本身的寫，這兒只是演示
            }
        });
