Retrofit+ReJava+OkHttp

• 依赖

//rxjava和retrofit
    implementation 'com.squareup.retrofit2:retrofit:2.1.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
    implementation 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
    implementation 'io.reactivex:rxandroid:1.2.0'

• 例如:service层

public interface RetrofitService {
   //登录
   @POST(HttpUrl.LOGIN_URL)
   @FormUrlEncoded
   Observable login(@Field("phone") String phone, @Field("pwd") String pwd);

   //注册
   @POST(HttpUrl.REGISTER_URL)
   @FormUrlEncoded
   Observable register(@Field("phone") String phone, @Field("pwd") String pwd);

   //banner
   @GET(HttpUrl.BANNER_URL)
   Observable banner();

   //获取首页
   @GET(HttpUrl.HOME_GOODS_URL)
   Observable information();

   //我的足迹
   @GET(HttpUrl.FOOTMARK_URL)
   Observable footMark(@Query("page") int page, @Query("count") int count, @Header("sessionId") String sessionId, @Header("userId") int userId);

   //我的商品列表归属标签查询商品信息
   @GET(HttpUrl.GOODS_LIST)
   Observable getGoodsList(@Query("labelId") String labelId,@Query("page") int page, @Query("count") int count);

}

• RetrofitUtls

public class RetrofitUtls {
    private static RetrofitUtls instance;
    private Retrofit mretrofit;
   
    private RetrofitUtls() {
        mretrofit = new Retrofit.Builder()
                .baseUrl(HttpUrl.BASE_URL) //baseurl必须以/结尾
                .addConverterFactory(GsonConverterFactory.create()) //添加数据解析器，即序列化器
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .client(OkHttpUtil.okHttpClient) //指定http客户端
                .build();
    }

    //单例模式
    public static RetrofitUtls getInstance() {
        if (instance == null) {
            instance = new RetrofitUtls();
        }
        return instance;
    }

    //泛型
    public T createApi(Class cls){
        T t=mretrofit.create(cls);
        return t;
    }
}

• model层

public class HomeModel {
    public void showHome(String keywords, final HomeCallBack homeCallBack){
        DataService service = RetrofitUtil.getInstance().createApi(DataService.class);
        service.showHome(keywords).subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer() {
                    @Override
                    public void onCompleted() {

                    }

                    @Override
                    public void onError(Throwable e) {
                        homeCallBack.onHomeFailer("错误");
                    }

                    @Override
                    public void onNext(HomeEntity homeEntity) {
                        List data = homeEntity.getData();
                        homeCallBack.onHomeSuccess(data);
                    }
                });
    }

    public void ondestroy() {

    }
}
