先写几个公共的封装类

retrofit的封装类

public class RetrofitUtils {

private static IGetService service = null;

//http://api.tianapi.com/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10

//单例模式

public static IGetService getInstance(){

if(service==null){

synchronized (RetrofitUtils.class){

if(service==null){

Retrofit retrofit = new Retrofit.Builder()

.baseUrl("http://api.tianapi.com")

.addConverterFactory(ScalarsConverterFactory.create())

.addCallAdapterFactory(RxJava2CallAdapterFactory.create())

.client(OkHttpUtils.getInstance())

.build();

service = retrofit.create(IGetService.class);

}

}

}

return service;

}

}okhttp的封装类

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(2000, TimeUnit.SECONDS)

.writeTimeout(2000,TimeUnit.SECONDS)

.readTimeout(2000,TimeUnit.SECONDS)

.addInterceptor(new LoggingInterceptor())

.addInterceptor(new CommonHeaderInterceptor())

.build();

}

}

}

return client;

}

}

LoggingInterceptor日志拦截器的封装

public class LoggingInterceptor implements Interceptor{

@Override

public Response intercept(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

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","aa");

builder.addHeader("User-Agent","android");

return chain.proceed(builder.build());

}

}观察者Observer的封装

//观察者的封装

public abstract class AbstractObserver implements Observer {

//不需要下面重写的四个方法,只需要自己写的两个抽象方法

public abstract void onSuccess(T t);

public abstract void onFailure();

@Override

public void onSubscribe(Disposable d) {

}

@Override

public void onNext(String result) {

//这里的s是请求网络传回来的string字符串

Type type = getClass().getGenericSuperclass();

Type[] types = ((ParameterizedType) type).getActualTypeArguments();

Class clazz = (Class) types[0];//强转成类对象

//使用gson解析

Gson gson = new Gson();

T t = (T) gson.fromJson(result,clazz);

//调用抽象方法onSuccess

onSuccess(t);

}

@Override

public void onError(Throwable e) {

onFailure();

}

@Override

public void onComplete() {

}

}Retrofit的接口

public interface IGetService {

/* @GET("/nba")

Observable get(@QueryMap Map map);*/

//-----------------------下面用于封装的请求

//http://api.tianapi.com/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10

//返回string字符串的请求方法,传后面整个url

@GET

Observable get1(@Url String url);//重载

@GET

Observable get1(@Url String url,@QueryMap Map map);

@FormUrlEncoded

@POST

Observable post1(@Url String url, @FieldMap Map map);

@POST

Observable post1(@Url String url);

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

public class APIFactory {

//单例模式

private static APIFactory factory = null;

public static APIFactory getInstance(){

if(factory==null){

synchronized (APIFactory.class){

if(factory==null){

factory = new APIFactory();

}

}

}

return factory;

}

//这里面写方法.

public void get1(String url, Map map, Observer observer){

//调用retrofit工具类的方法

RetrofitUtils.getInstance().get1(url, map)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(observer);

}

public void get1(String url,Observer observer){

RetrofitUtils.getInstance().get1(url)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(observer);

}

public void post1(String url,Map map,Observer observer){

RetrofitUtils.getInstance().post1(url,map)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(observer);

}

public void post1(String url,Observer observer){

RetrofitUtils.getInstance().post1(url)

.subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(observer);

}

}在model层里面调用APIFactory里面的4个方法get1,post1,

//具体的model层

public class LoginModelImpl {

//model层处理数据,请求网络

public void getData(final LoginModelCallBack loginModelCallBack) {

//http://api.tianapi.com/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10

Map map = new HashMap<>();

map.put("key","71e58b5b2f930eaf1f937407acde08fe");

map.put("num","10");

/* Retrofit retrofit = new Retrofit.Builder()

.baseUrl("http://api.tianapi.com")

.addCallAdapterFactory(RxJava2CallAdapterFactory.create())

.addConverterFactory(GsonConverterFactory.create())

.build();

IGetService service = retrofit.create(IGetService.class);

service.get(map).subscribeOn(Schedulers.io())

.observeOn(AndroidSchedulers.mainThread())

.subscribe(new Consumer() {

@Override

public void accept(Bean bean) throws Exception {

loginModelCallBack.success(bean);

}

});*/

//------------

//http://api.tianapi.com/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10

//调用apifactory

//传参map集合

APIFactory.getInstance().get1("/nba", map, new AbstractObserver() {

@Override

public void onSuccess(Bean bean) {

// System.out.println("beanget传参 ="+bean.getNewslist().toString());

}

@Override

public void onFailure() {

// System.out.println("异常了");

}

});

//不传参,直接传路径

APIFactory.getInstance().get1("/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10", new AbstractObserver() {

@Override

public void onSuccess(Bean bean) {

// System.out.println("beanget不传参 ="+bean.getNewslist().toString());

}

@Override

public void onFailure() {

// System.out.println("异常了");

}

});

//不传参直接传路径post

APIFactory.getInstance().post1("/nba/?key=71e58b5b2f930eaf1f937407acde08fe&num=10", new AbstractObserver() {

@Override

public void onSuccess(Bean bean) {

System.out.println("beanpost不带参数 ="+bean.getNewslist().toString());

loginModelCallBack.success(bean);

}

@Override

public void onFailure() {

System.out.println("异常了");

}

});

/* //传参 post路径,不好使

APIFactory.getInstance().post1("/nba", map, new AbstractObserver() {

@Override

public void onSuccess(Bean bean) {

System.out.println("beanpost带参数 ="+bean.getNewslist().toString());

}

@Override

public void onFailure() {

System.out.println("异常了");

}

});*/
