Retrofit框架的使用

一、Get请求

private void Retrofit_Get() {    Retrofit retrofit = new Retrofit.Builder()            .baseUrl(Urls.baseUrl)            .build();    MyServerInterface myServerInterface = retrofit.create(MyServerInterface.class);    Call<ResponseBody> call = myServerInterface.getLastJsonString();    call.enqueue(new Callback<ResponseBody>() {        @Override        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {            if (response.isSuccessful()) {                String json = null;                try {                    json = response.body().string();                    mTextView.setText(json);                } catch (Exception e) {                    e.printStackTrace();                }            }        }        @Override        public void onFailure(Call<ResponseBody> call, Throwable t) {            Log.d(TAG, "onFailure() called with: " + "call = [" + call + "], t = [" + t + "]");        }    });}

服务接口可以这样写：

public interface MyServerInterface {    @GET("341-2?maxResult=20&page=&showapi_appid=19170&showapi_sign=248b52a91c9d4d2fa5ca1ddd16ee7832")    Call<ResponseBody> getLastJsonString();

    @GET("341-2?maxResult=20&page=&showapi_appid=19170&showapi_sign=248b52a91c9d4d2fa5ca1ddd16ee7832")    Call<JokeModel> getJson2Model();}
