Retrofit和RxJava的封装

导入依赖

//retrofit的依赖  compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4'  compile'com.squareup.retrofit2:converter-gson:2.0.0-beta4'  compile 'com.squareup.retrofit2:converter-scalars:2.0.0'  compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'  //rxjava的依赖  compile 'io.reactivex.rxjava2:rxandroid:2.0.1'  compile 'io.reactivex.rxjava2:rxjava:2.1.7'

retrofit的封装类

import retrofit2.Retrofit;import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;import retrofit2.converter.gson.GsonConverterFactory;import retrofit2.converter.scalars.ScalarsConverterFactory;/** * Created by muhanxi on 17/12/5. */public class RetrofitUtils {    private static APIService service  = null ;    public static APIService getInstance(){        if(service == null){            synchronized (RetrofitUtils.class){                Retrofit retrofit = new Retrofit.Builder()                        .baseUrl("http://m.yunifang.com")                        .addConverterFactory(ScalarsConverterFactory.create())                        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())                        .client(OkHttpUtils.getInstance())                        .build();                service = retrofit.create(APIService.class);            }        }        return service;    }}

okhttp的封装类

import java.util.concurrent.TimeUnit;import okhttp3.OkHttpClient;/** * Created by muhanxi on 17/12/5. * @author muhanxi */public class OkHttpUtils {    private static OkHttpClient client = null ;    public static OkHttpClient getInstance(){        if(client == null){            synchronized (OkHttpUtils.class){                if(client == null){                    client = new OkHttpClient.Builder()                            .connectTimeout(20000, TimeUnit.SECONDS)                            .writeTimeout(20000,TimeUnit.SECONDS)                            .readTimeout(20000,TimeUnit.SECONDS)                            //.addInterceptor(new CommonHeaderInterceptor())                            //.addInterceptor(new LoggingInterceptor())                            .build();                }            }        }        return client;    }

观察者Observer的封装

import com.google.gson.Gson;import com.google.gson.JsonSyntaxException;import java.lang.reflect.ParameterizedType;import java.lang.reflect.Type;import io.reactivex.Observer;import io.reactivex.disposables.Disposable;/** * Created by muhanxi on 17/12/5. */public abstract class AbstractObserver<T> implements Observer<String> {    public abstract void onSuccess(T t);    /**     * 1  当前 网络异常     * 2  json 解析异常     * 2  未知异常     * @param code     */    public abstract void onFailure(int code);    @Override    public void onSubscribe(Disposable d) {    }    @Override    public void onNext(String result) {        try {            Type type =  getClass().getGenericSuperclass() ;            Type [] types =  ((ParameterizedType)type).getActualTypeArguments() ;            Class clazz = (Class) types[0] ;            Gson gson = new Gson();            T t = (T)  gson.fromJson(result,clazz);            onSuccess(t);        } catch (JsonSyntaxException e) {            e.printStackTrace();            onFailure(2);        }catch (Exception e){            e.printStackTrace();            onFailure(3);        }    }    @Override    public void onError(Throwable e) {        onFailure(1);        System.out.println(e        );    }    @Override    public void onComplete() {    }}

Retrofit的接口

import java.util.Map;import io.reactivex.Observable;import retrofit2.http.FieldMap;import retrofit2.http.FormUrlEncoded;import retrofit2.http.GET;import retrofit2.http.POST;import retrofit2.http.QueryMap;import retrofit2.http.Url;/** * Created by muhanxi on 17/12/5. */public interface APIService {    @GET    Observable<String> get(@Url String url, @QueryMap Map<String,String> map);    @GET    Observable<String> get(@Url String url);    @FormUrlEncoded    @POST    Observable<String> post(@Url String url, @FieldMap Map<String,String> map);}

APIFactory.java这个类里面有对应的四个方法get1, post1

import java.util.Map;import io.reactivex.Observer;import io.reactivex.android.schedulers.AndroidSchedulers;import io.reactivex.schedulers.Schedulers;/** * Created by muhanxi on 17/12/5. */public class APIFactory {    private APIFactory(){}    private  static APIFactory factory = null ;    public static APIFactory getInstance(){        if(factory == null){            synchronized (APIFactory.class){                if(factory == null){                    factory = new APIFactory();                }            }        }        return factory;    }    public void get(String url, Map<String,String> map, Observer<String> observer){        RetrofitUtils.getInstance().get(url,map)                .subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(observer);    }    public void get(String url,Observer<String> observer){        RetrofitUtils.getInstance().get(url)                .subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(observer);    }    public void post(String url,Map<String,String> map,Observer<String> observer){        RetrofitUtils.getInstance().post(url,map)                .subscribeOn(Schedulers.io())                .observeOn(AndroidSchedulers.mainThread())                .subscribe(observer);    }}

LoggingInterceptor日志拦截器的封装

import java.io.IOException;import okhttp3.Interceptor;import okhttp3.Request;import okhttp3.Response;class LoggingInterceptor implements Interceptor {  @Override public Response intercept(Interceptor.Chain chain) throws IOException {    Request request = chain.request();    long t1 = System.nanoTime();    Response response = chain.proceed(request);    long t2 = System.nanoTime();    System.out.println(" this request  url  " + response.request().url() + "  "  + (t2 - t1)/1000000);    return response;  }}

CommonHeaderInterceptor公共的请求头拦截器

import java.io.IOException;import okhttp3.Interceptor;import okhttp3.Request;import okhttp3.Response;/** * Created by muhanxi on 17/12/5. */public class CommonHeaderInterceptor implements Interceptor {    @Override    public Response intercept(Chain chain) throws IOException {        Request request =  chain.request();        Request.Builder builder =  request.newBuilder() ;        builder.addHeader("key","11");        builder.addHeader("User-Agent","android");        return chain.proceed(builder.build());    }}

public class AddModel {    public void getData(String pid, final IModel iModel){        Map<String, String> map = new HashMap<>();//        https://www.zhaoapi.cn/product/addCart?uid=1245&pid=45&token=86B6DEFFD9DEF5FF93C3E7BA5560A0E6&Source=android        map.put("uid","1245");        map.put("pid",pid);        map.put("token","86B6DEFFD9DEF5FF93C3E7BA5560A0E6");        map.put("Source","android");        APIFactory01.getInstance().post1("/product/addCart", map, new AbstractObserver01<AddBean>() {            @Override            public void onSuccess(AddBean addBean) {                iModel.success(addBean);            }            @Override            public void onFailure() {            }        });    }    public interface IModel{        //成功 失败        public void success(AddBean bean);        public void failrue();    }}

public interface AddView {    //成功 失败    public void success(AddBean bean);    public void failrue();}

public class AddPresenter {    AddView view;    private final AddModel model;    public AddPresenter(AddView view) {        this.view = view;        model = new AddModel();    }    public void shangpin(String pid){        model.getData(pid, new AddModel.IModel() {            @Override            public void success(AddBean bean) {                view.success(bean);            }            @Override            public void failrue() {            }        });    }    //防止内存遗漏    public void datach(){        this.view = null;    }}
