Retrofit2+Rxjava2网络请求框架的封装

基于Retrofit和Rxjava2的联网框架,建造者模式构建RestClient,请求方法的封装,支持配置加载动画，链式调用。统一请求拿到后台返回的原始数据。

先来看网络请求示例代码

链式调用,简洁明了

     * 请求网络     *     * @param view     */    public void request(View view) {        RestClient restClient = RestClient.builder()                .url("data/Android/10/1")                .load(this)//                .params(new WeakHashMap<String, Object>())                .success(new ISuccess() {                    @Override                    public void onSuccess(String response) {                    }                })                .error(new IError() {                    @Override                    public void onError(int code, String msg) {                    }                })                .build();        restClient.request(HttpMethod.GET);    }这里写代码片

添加依赖这里用了依赖的统一管理

--------------------dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    compile rootProject.ext.dependencies.appcompatV7    implementation rootProject.ext.dependencies.constraintLayout    compile rootProject.ext.dependencies.design    compile rootProject.ext.dependencies.cardView    compile rootProject.ext.dependencies.systembartint    //Retrofit和Rxjava    compile rootProject.ext.dependencies.rxjava2    compile rootProject.ext.dependencies.rxandroid2    compile rootProject.ext.dependencies.retrofit2    compile rootProject.ext.dependencies.converterGson    compile rootProject.ext.dependencies.converterScalars    compile rootProject.ext.dependencies.adapterRxjava2    //加载动画    compile rootProject.ext.dependencies.aviloader    //okhttp3拦截器    compile rootProject.ext.dependencies.loggerinterceptor    testImplementation rootProject.ext.dependencies.junit    androidTestImplementation rootProject.ext.dependencies.runner    androidTestImplementation rootProject.ext.dependencies.espresso}

HttpMethod 枚举类定义请求方法

 * Created by kevin321vip on 2017/12/14. * 请求方法,枚举类 */public enum HttpMethod {    GET,    POST,    POST_RAW,    PUT,    PUT_RAW,    DELETE,    UPLOAD这里写代码片

RestService 定义统一的ApiService接口

 * Created by kevin321vip on 2017/12/14. * Api接口 */public interface RestService {    @GET    Observable<String> get(@Url String url, @QueryMap WeakHashMap<String, Object> params);    @FormUrlEncoded    @POST    Observable<String> post(@Url String url, @QueryMap WeakHashMap<String, Object> params);    @POST    Observable<String> post(@Url String url, ResponseBody body);    @FormUrlEncoded    @PUT    Observable<String> put(@Url String url, @FieldMap WeakHashMap<String, Object> params);    @PUT    Observable<String> putRaw(@Url String url, @Body RequestBody body);    @DELETE    Observable<String> delete(@Url String url, @QueryMap WeakHashMap<String, Object> params);    @Streaming    @GET    Observable<ResponseBody> download(@Url String url, @QueryMap WeakHashMap<String, Object> params);    @Multipart    @POST    Observable<String> upload(@Url String url, @Part MultipartBody.Part file);}这里写代码片

RestCreatorh（关键类）

**主要的Retroft的初始化配置,以及返回ApiService对象
1、主要是静态内部类Hodler的方式的单例对象获取**
2、.addConverterFactory(ScalarsConverterFactory.create())保证返回的是原始请求数据，方便根据状态等自行做过滤校验相关处理
3、ParamsHodler 单例管理Params多处使用不用重复new对象**

    /**     * 构建全局的Retrofit客户端     * .baseUrl(UrlConstance.BaseUrl)     * .addConverterFactory(GsonConverterFactory.create())     * http://gank.io/api/data/Android/10/1     */    private static final class RetrofitHodler {        private static final Retrofit RETROFIT_CLIENT = new Retrofit.Builder()                .client(OkHttpHodler.OK_HTTP_CLIENT)                .baseUrl("http://gank.io/api/")                .addConverterFactory(ScalarsConverterFactory.create())                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())                .build();    }    /**     * OkhttpHodler     */    private static final class OkHttpHodler {        private static final OkHttpClient OK_HTTP_CLIENT = new OkHttpClient.Builder()                .connectTimeout(UrlConstance.TimeOut, TimeUnit.SECONDS)                .build();    }    /**     * RestService     */    private static final class RestServiceHodler {        private static final RestService REST_SERVICE = RetrofitHodler.RETROFIT_CLIENT.create(RestService.class);    }    /**     * Params的Hodler     */    private static final class ParamsHodler {        private static final WeakHashMap<String, Object> PARAMS = new WeakHashMap<>();    }    /**     * 获取参数     *     * @return     */    public static WeakHashMap<String, Object> getParams() {        return ParamsHodler.PARAMS;    }    /**     * 获取Service     */    public static RestService getService() {        return RestServiceHodler.REST_SERVICE;    }}这里写代码片

RestClient 关键类*

用来发起网络请求,通过Build模式传入请求参数和构建请求体

     * 通过建造者模式传参     */    public static RestClientBuilder builder() {        return new RestClientBuilder();    }    /**     * 发起网络请求     */    public void request(HttpMethod method) {    //得到ApiService对象,通过相应的请求方法给observable实例化 发起请求        final RestService service = RestCreator.getService();        Observable<String> observable = null;        if (REQUEST != null) {            REQUEST.onRequestStart();        }        if (LOADER_STYLE != null) {            LyonLoader.showLoading(CONTEXT, LOADER_STYLE);        }        switch (method) {            case GET:                observable = service.get(URL, PARAMS);                break;            case POST:                service.post(URL, PARAMS);                observable = service.post(URL, PARAMS);                break;            case POST_RAW://                observable = service.postRaw(URL, BODY);                break;            case PUT:                observable = service.post(URL, PARAMS);                break;            case PUT_RAW:                service.putRaw(URL, BODY);                break;            case DELETE:                observable = service.delete(URL, PARAMS);                break;            case UPLOAD:                final RequestBody requestBody =        RequestBody.create(MediaType.parse(MultipartBody.FORM.toString()), FILE);                final MultipartBody.Part body =                        MultipartBody.Part.createFormData("file", FILE.getName(), requestBody);                observable = service.upload(URL, body);                break;            default:                break;        }        //发起网络请求,并在回调中将请求的数据回调出去        if (observable != null) {            observable.subscribeOn(Schedulers.io())                    .observeOn(AndroidSchedulers.mainThread())                    .subscribe(new Observer<String>() {                        @Override                        public void onSubscribe(Disposable d) {                        }                        @Override                        public void onNext(String s) {                            if (SUCCESS != null) {                                SUCCESS.onSuccess(s);                            }                            LyonLoader.stopLoading();                            ToastUtils.show("请求成功" + s);                        }                        @Override                        public void onError(Throwable e) {                            LyonLoader.stopLoading();                            if (ERROR != null) {                                ERROR.onError(0, e.getMessage());                            }                            ToastUtils.show("请求失败" + e.getMessage());                        }                        @Override                        public void onComplete() {                        }                    });        }    }    /**     * get方法     */    public void get() {        request(HttpMethod.GET);    }    /**     * post方法     */    public void post() {        request(HttpMethod.POST);    }}**在Retrofit 的联网回调中将请求结果根据传入的回调接口相应的回调出去**

RestClientBuilder 构造器

RestClient的构造器,用于传入联网请求的配置信息,构造Reclient对象

关于Loader就不介绍了,用了大神的：*com.wang.avi:library:2.1.3 做了一定的封装*
