RetrofitCache let retrofit2,okhttp3,rxjava add cache so easy. You can config cache strategy with each api by annotation.Also you can config mock data with each api easily.

## Why use?

- Api server do not config http cache strategy
- Third part lib config cache strategy not easy
- Add mock data to each api very easily

## Demo

- Not have cache

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

- Cache time 20 seconds

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

- Cache time 20 minutes

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

- Default cache time 0 seconds

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

- Default force cache without network, if forceCacheNoNet = false will break this rule

 ```
@Cache(forceCacheNoNet = false)
@GET("users")
Observable<HttpResult> test();
 ```

- Add mock data(if use value,assets,url same time, it will deal by this sort )

 ```
@Mock(value = "{\"data\":\"mockdata\"}") //mock ram data
@GET("users")
Observable<HttpResult> test();
 ```

 ```
@Mock(assets = "mock/mock.json") //mock data from assets
@GET("users")
Observable<HttpResult> test();
 ```

 ```
@Mock(url = "http://url.com/test") //mock data from new url
@GET("users")
Observable<HttpResult> test();
  ```


> Cache just with http Get method

## How to use

 - Add jcenter lib,notice chose different with you project

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

 - Init in Android Application

 ```
RetrofitCache.getInstance().init(this);
 ```

Also can modify default config, default value time=0,timeUnit = TimeUnit.SECONDS

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

 - OkHttpClient config cache dir

 ```
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();
...

 ```

- okhttp add Interceptor

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

//clientBuilder.addInterceptor(new MockInterceptor()); //Only add this interceptor if only use Mock
clientBuilder.addInterceptor(new CacheForceInterceptorNoNet());
clientBuilder.addNetworkInterceptor(new CacheInterceptorOnNet());
...

 ```


- Add retrofit object

```
Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(url)
                .client(getOkHttpClient())
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();
RetrofitCache.getInstance().addRetrofit(retrofit);
```
-  **Add rx Observable compose**

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

```


## Further


- setCacheInterceptorListener to set whether can cache by each api

```
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;
            }
});

```


- Enable mock data , if your release api ok,you can set false

```
RetrofitCache.getInstance().enableMock(false);
```
- Ignore some param. If you add some param in url, you can call addIgnoreParam.

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

## Proguard

```
-keepattributes *Annotation*,InnerClasses

-dontwarn ren.yale.android.retrofitcachelib.**
-keep class ren.yale.android.retrofitcachelib.** { *; }

#retrofit2
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions

-dontwarn org.robovm.**
-keep class org.robovm.** { *; }

#okhttp3
-dontwarn com.squareup.okhttp3.**
-keep class com.squareup.okhttp3.** { *;}
-keep class okhttp3.** { *;}
-keep class okio.** { *;}
-dontwarn sun.security.**
-keep class sun.security.** { *;}
-dontwarn okio.**
-dontwarn okhttp3.**

#rxjava
-dontwarn rx.**
-keep class rx.** { *; }

-dontwarn sun.misc.**
-keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* {

}
-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef {
 rx.internal.util.atomic.LinkedQueueNode producerNode;
}
-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef {

}

```


## Proguard(retrofit2+okhttp3+rxjava1)

```
-dontwarn ren.yale.android.retrofitcachelib.**
-keep class ren.yale.android.retrofitcachelib.** { *; }

###retrofit2 2.5.0
-keepclasseswithmembernames class retrofit2.HttpServiceMethod {*;}
-keepclasseswithmembernames class retrofit2.RequestFactory {*;}

#retrofit2,okhttp3,rxjava1 and other Proguard config add by yourself

```
## Proguard(retrofit2+okhttp3+rxjava2)
