网络请求工具类:

@POST
@FormUrlEncoded
Observable<JokeBean> getJokeSuccess(@Url String url, @FieldMap Map<String,String> map);

网络请求工具类的使用:

RetrofitUtil.getInstence()
        .API()
        .getJokeSuccess(HttpConfig.jokeUrl, map)
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Observer<JokeBean>() {
            @Override
            public void onSubscribe(Disposable d) {

            }

            @Override
            public void onNext(JokeBean value) {
                getJokeListener.getJokeSuccess(value.getData());
                Log.d(TAG, "onNext: ==========" + value.getMsg());
            }

            @Override
            public void onError(Throwable e) {
                getJokeListener.getJokeError(e.toString());
            }

            @Override
            public void onComplete() {

            }
        });
