okhttp,retrofit,rxjava

1.OkHttp
enqueue [ɪn'kjuː] (n. 排队；入队；队列)异步调用
execute ['eksɪkjuːt](vt. 实行；执行；处死) 同步调用

 看源码知在final class AsyncCall extends NamedRunnable 只有execute方法   来到NamedRunnable
 enqueue其实就是在线程run方法中调用execute

OkHttpClient okHttpClient = new OkHttpClient();
final Request request = new Request.Builder()
    .url(hongdou)
    .build();
Call call = okHttpClient.newCall(request);
call.enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
    Log.d("MainActivity", e.toString());
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
    String result = response.body().string();
    Log.d("MainActivity", result);
    }
});

2.Retrofit
通过接口获取call对象 然后调用enqueue或者execute
直接通过GsonConverterFactory.create()把得到的String转换成对应的javaBean

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BaseUrl)
    .addConverterFactory(GsonConverterFactory.create())
    .build();
WeatherService weatherService = retrofit.create(WeatherService.class);
retrofit2.Call<ResponseWeather> weather = weatherService.getWeather("");
weather.enqueue(new retrofit2.Callback<ResponseWeather>() {
    @Override
    public void onResponse(retrofit2.Call<ResponseWeather> call, retrofit2.Response<ResponseWeather> response) {
    ResponseWeather body = response.body();
    Log.d("MainActivity", body.toString());
    }

    @Override
    public void onFailure(retrofit2.Call<ResponseWeather> call, Throwable t) {
    Log.d("MainActivity", "onFailure");
    }
}); 

    @POST("Langshi/ds/android/weather4")
    Call<ResponseWeather> getWeather(@Body String deviceId);

3.rxJava
获取对应的Observable对象然后获取到的数据发送到onNext()

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BaseUrl1)
    .addConverterFactory(GsonConverterFactory.create())
    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
    .build();
WeatherService service = retrofit.create(WeatherService.class);
service.getWuxiData()
    .subscribeOn(Schedulers.io())
    .subscribe(new Consumer<WuxiHongdou>() {
        @Override
        public void accept(WuxiHongdou yinchaun) throws Exception {
        Log.d("MainActivity", "yinchaun:" + yinchaun);
        }
    }, new Consumer<Throwable>() {
        @Override
        public void accept(Throwable throwable) throws Exception {
        Log.d("MainActivity", "throwable:" + throwable);
        }
    });
