本文介绍如何使用Retrofit结合RxJava进行高效的网络请求处理，包括GET和POST请求的实现，通过观察者模式处理响应，以及错误处理机制。

创建BaseService

import java.util.Map;

import io.reactivex.Observable;
import okhttp3.ResponseBody;
import retrofit2.http.GET;
import retrofit2.http.POST;
import retrofit2.http.QueryMap;
import retrofit2.http.Url;


public interface BaseService {
    @GET
    Observable<ResponseBody> get(@Url String url, @QueryMap Map<String, String> map);

    @POST
    Observable<ResponseBody> post(@Url String url, @QueryMap Map<String, String> map);
}



联网请求工具类


import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import io.reactivex.Observer;
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.Disposable;
import io.reactivex.schedulers.Schedulers;
import okhttp3.ResponseBody;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;


public class HttpHelper11 {
    private  BaseService mBaseService;

    public HttpHelper11(){
        Retrofit retrofit=new Retrofit.Builder()
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .baseUrl("http://www.zhaoapi.cn/")
                .build();
        mBaseService=retrofit.create(BaseService.class);
    }

    //get请求
    public HttpHelper11 get(String url, Map<String,String> map){
        if(map==null){
            map=new HashMap<>();
        }
        mBaseService.get(url,map)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(observer);
        return this;
    }

    //post请求
    public HttpHelper11 post(String url, Map<String,String> map){
        if(map==null){
            map=new HashMap<>();
        }
        mBaseService.post(url,map)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(observer);
        return this;
    }


    private Observer observer=new Observer<ResponseBody>() {
        @Override
        public void onSubscribe(Disposable d) {

        }

        @Override
        public void onNext(ResponseBody responseBody) {
            try {
                String data= responseBody.string();
                listener.success(data);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onError(Throwable e) {
            String error= e.getMessage();
            listener.fail(error);
        }

        @Override
        public void onComplete() {

        }
    };

    private HttpListener listener;

    public void result(HttpListener listener){
        this.listener=listener;
    }

    public interface HttpListener {
        void success(String data);
        void fail(String error);
    }
}
