禁用 okhttp 缓存

Question

i know to disable cache of okhttp is to call Request.cacheControl(CacheControl.FORCE_NETWORK) . Is it possible to set the cacheControl from OkHttpClient.class? Because i have 1 client for all my request. So i want to disable cache for all the request by disabling it from the okhttpClient

Answer 1

Use this to build Retrofit and provide cache as null the API will not cache anything.

private OkHttpClient createOkHttpClient() {
    return new OkHttpClient.Builder()
            ...
            .cache(null)
            .build();
}

Answer 2

add interceptor to your client, and add cache control header in interceptor.check sample code below:

    Interceptor interceptor = new Interceptor() {
        @Override public Response intercept(Chain chain) throws IOException {
            Request request = chain.request();
            Request.Builder builder = request.newBuilder().addHeader("Cache-Control", "no-cache");
            request = builder.build();
            return chain.proceed(request);
        }
    };

    OkHttpClient mClient = new OkHttpClient.Builder()
            .addInterceptor(interceptor)
            .build();
