问题 与Retrofit 2并行执行http请求

感谢Colin Gillespie链接，我已经实现了杰克沃顿所说的结果，这就是结果：

 public static IStockChart getMyApiService() {
        OkHttpClient client=new OkHttpClient();
        Dispatcher dispatcher=new Dispatcher();
        dispatcher.setMaxRequests(3);
        client.setDispatcher(dispatcher);
       // OkHttpClient client = new OkHttpClient();
       //  HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
       //  interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
       //  client.interceptors().add(interceptor);
        if(myService ==null){
            Retrofit retrofit=new Retrofit.Builder()
                    .baseUrl("http://chartapi.finance.yahoo.com/")
                    .addConverterFactory(JsonpGsonConverterFactory.create())
                    .client(client)
                    .build();
            myService=retrofit.create(IStockChart.class);
            return myService;
        } else {
            return myService;
        }



    }
