RetrofitCache

English

RetrofitCache让retrofit2+okhttp3+rxjava 配置缓存如此简单。通过注解配置，可以针对每一个接口灵活配置缓存策略；同时让每一个接口方便支持数据模拟，可以代码减小侵入性，模拟数据可以从内存，Assets，url轻松获取。

为什么使用RetrofitCache

服务端接口不严格按照http缓存策略配置，有些不会针对每一个请求单独配置缓存策略
第三方缓存库不是很方便的针对每一个接口进行缓存策略配置，侵入性比较大
很方便的针对每个接口添加模拟数据

调用例子

不走缓存例子

@GET("users")
Observable<HttpResult> test();

缓存设置为20秒

@Cache(time = 20)
@GET("users")
Observable<HttpResult> test();

缓存设置为20分钟

@Cache(time = 20,timeUnit = TimeUnit.MINUTES)
@GET("users")
Observable<HttpResult> test();

默认时间缓存,默认是0秒

@Cache()
@GET("users")
Observable<HttpResult> test();

默认在无网的时候强制走缓存，forceCacheNoNet=false时无网络时不强制缓存
```
@Cache(forceCacheNoNet = false)
@GET("users")
Observable<HttpResult> test();
```

添加模拟数据（value,assets,url同时都配置的话，就按照这个顺序处理）

@Mock(value = "{\"data\":\"mockdata\"}") //模拟内存数据
@GET("users")
Observable<HttpResult> test();

@Mock(assets = "mock/mock.json") //从assets获取模拟数据
@GET("users")
Observable<HttpResult> test();

@Mock(url = "http://url.com/test") //从新的url请求数据
@GET("users")
Observable<HttpResult> test();

缓存只对http Get请求有效；如果要问为什么，可以问问后台开发同学

使用方法:

添加 jcenter lib,注意根据自己的库选择

compile 'ren.yale.android:retrofitcachelib:1.1.1'   //retrofit2+okhttp3+rxjava1
compile 'ren.yale.android:retrofitcachelibrx2:1.1.1'   //retrofit2+okhttp3+rxjava2

在Android Application里初始化
```
RetrofitCache.getInstance().init(this);
```

也可以修改默认配置，默认time=0，timeUnit = TimeUnit.SECONDS

RetrofitCache.getInstance().init(this).setDefaultTimeUnit(TimeUnit.MINUTES).setDefaultTime(1);

OkHttpClient初始化时配置缓存目录

okhttp3.OkHttpClient.Builder clientBuilder=new okhttp3.OkHttpClient.Builder();
...
int cacheSize = 200 * 1024 * 1024;
File cacheDirectory = new File(mContext.getCacheDir(), "httpcache");
Cache cache = new Cache(cacheDirectory, cacheSize);
OkHttpClient client =  clientBuilder.cache(cache).build();
...

给okhttp添加拦截器


okhttp3.OkHttpClient.Builder clientBuilder=new okhttp3.OkHttpClient.Builder();
...

//clientBuilder.addInterceptor(new MockInterceptor()); //如果只用Mock模拟功能,只需添加这个拦截器 clientBuilder.addInterceptor(new CacheForceInterceptorNoNet()); clientBuilder.addNetworkInterceptor(new CacheInterceptorOnNet()); ...


 > 添加CacheForceInterceptorNoNet作用是在无网时强制走缓存,如果只添加了CacheInterceptorOnNet,那么在有网和无网的缓存策略就会一样

- 添加retrofit对象

Retrofit retrofit = new Retrofit.Builder() .baseUrl(url) .client(getOkHttpClient()) .addConverterFactory(GsonConverterFactory.create()) .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) .build(); RetrofitCache.getInatance().addRetrofit(retrofit);

-  **添加 rx Observable compose**

api.test().compose(CacheTransformer.emptyTransformer())...


## 进阶

- setCacheInterceptorListener 设置是否每一个接口都缓存

RetrofitCache.getInstance().setCacheInterceptorListener( new CacheInterceptorListener() { @Override public boolean canCache(Request request,Response response) { String res = ""; try { res = response.body().string(); } catch (IOException e) { e.printStackTrace(); } return true; } });


- 设置是否走模拟数据,比如说在正式接口好了后可以如下设置，让模拟数据失效

RetrofitCache.getInstance().enableMock(false);


- 忽略某个参数;如果你对原url增加参数，可以设置忽略

RetrofitCache.getInstance().addIgnoreParam("access_token");


## 混淆配置（retrofit2+okhttp3+rxjava1）

-dontwarn ren.yale.android.retrofitcachelib. -keep class ren.yale.android.retrofitcachelib. { ; } -keepclasseswithmembernames class rx.Observable { ; } -keepclasseswithmembernames class rx.internal.operators.OnSubscribeLift { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava.RxJavaCallAdapterFactory { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava.RxJavaCallAdapterFactory$CallOnSubscribe { ; } -keepclasseswithmembernames class retrofit2.Retrofit { ; } -keepclasseswithmembernames class retrofit2.ServiceMethod { ; } -keepclasseswithmembernames class retrofit2.OkHttpCall { ; }

retrofit2 2.5.0

-keepclasseswithmembernames class retrofit2.HttpServiceMethod {;} -keepclasseswithmembernames class retrofit2.RequestFactory {;}

retrofit2,okhttp3,rxjava1等其它混淆配置请自行添加

## 混淆配置（retrofit2+okhttp3+rxjava2）

-dontwarn ren.yale.android.retrofitcachelibrx2. -keep class ren.yale.android.retrofitcachelibrx2. { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava2.BodyObservable { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava2.ResultObservable { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava2.CallEnqueueObservable { ; } -keepclasseswithmembernames class retrofit2.adapter.rxjava2.CallExecuteObservable { ; } -keepclasseswithmembernames class retrofit2.Retrofit { ; } -keepclasseswithmembernames class retrofit2.ServiceMethod { ; } -keepclasseswithmembernames class retrofit2.OkHttpCall { ; }
