自定义网路请求工具类:

public class RetrofitUtils {    //单例模式    private static volatile RetrofitUtils instance;    private Flowable<SelBean> selBeanFlowable;    private Flowable<DelBean> delBeanFlowable;    private RetrofitUtils(Map<String,String> map, String uri, int tag){        OkHttpClient build = new OkHttpClient.Builder()                .addInterceptor(new Logger())                .build();        Retrofit build1 = new Retrofit.Builder()                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())                .addConverterFactory(GsonConverterFactory.create(new Gson()))                .client(build)                .baseUrl(uri)                .build();        RxJava rxJava = build1.create(RxJava.class);        Log.e("---TAG值:",tag+"");        if(tag==0){            selBeanFlowable = rxJava.Sel_Car(map);        }else        if(tag==1){            delBeanFlowable = rxJava.Del_Car(map);        }    };    public static RetrofitUtils getInstance(Map<String,String> map,String uri,int tag){        instance = new RetrofitUtils(map,uri,tag);        return instance;    }    public Flowable<SelBean> getSelFlowable(){        return selBeanFlowable;    }    public Flowable<DelBean> getDelFlowable(){        return delBeanFlowable;    }}

自定义拦截器:

public class Logger implements Interceptor {    @Override    public Response intercept(Chain chain) throws IOException {        Request original = chain.request();        HttpUrl url=original.url().newBuilder()                .addQueryParameter("source","android")                .build();        //添加请求头        Request request = original.newBuilder()                .url(url)                .build();        return chain.proceed(request);    }}

Retrofit的网络请求:

public interface RxJava {    @GET("product/getCarts")    Flowable<SelBean> Sel_Car(@QueryMap Map<String, String> map);    @GET("product/deleteCart")    Flowable<DelBean> Del_Car(@QueryMap Map<String, String> map);}
