Retrofit缓存

//2.通过Retrofit中的方法client(this.retrofithuangcun())传入类名

//1.以下是我写好的类首先将其复制到你的代码中

public OkHttpClient retrofithuangcun(){

String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/meCache";

File httpCacheDirectory =new File(path);

if (!httpCacheDirectory.exists()){

httpCacheDirectory.mkdir();

}

//        File httpCacheDirectory = new File(context.getExternalCacheDir(), "responses");

//设置缓存 10M

        int cacheSize =10 *1024 *1024;

final Cache cache =new Cache(httpCacheDirectory, cacheSize);

OkHttpClient client =new OkHttpClient.Builder().cache(cache).addNetworkInterceptor(new Interceptor() {

@Override

            public okhttp3.Response intercept(Chain chain)throws IOException {

Request request = chain.request();

okhttp3.Response proceed = chain.proceed(request);

proceed = proceed.newBuilder()

.removeHeader("Pragma")

.removeHeader("Cache-Control")

.addHeader("Cache-Control","max-age="+20000)

.build();

return proceed;

}

}).build();

return client;

}
