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();
}
