问题描述
最近学习了OkHttp3.01、怎么把数据写入缓存？2、怎么从缓存中读取数据？
问题解答
回答1：参考这里
回答2：private final OkHttpClient client; public CacheResponse(File cacheDirectory) throws Exception { int cacheSize = 10 * 1024 * 1024; // 10 MiB Cache cache = new Cache(cacheDirectory, cacheSize); client = new OkHttpClient.Builder().cache(cache).build(); } public void run() throws Exception { Request request = new Request.Builder().url('http://publicobject.com/helloworld.txt').build(); Response response1 = client.newCall(request).execute(); if (!response1.isSuccessful()) throw new IOException('Unexpected code ' + response1); String response1Body = response1.body().string(); System.out.println('Response 1 response: ' + response1); System.out.println('Response 1 cache response: ' + response1.cacheResponse()); System.out.println('Response 1 network response: ' + response1.networkResponse()); Response response2 = client.newCall(request).execute(); if (!response2.isSuccessful()) throw new IOException('Unexpected code ' + response2); String response2Body = response2.body().string(); System.out.println('Response 2 response: ' + response2); System.out.println('Response 2 cache response: ' + response2.cacheResponse()); System.out.println('Response 2 network response: ' + response2.networkResponse()); System.out.println('Response 2 equals Response 1? ' + response1Body.equals(response2Body)); }
