如何告诉OkHttpClient忽略缓存并强制从服务器刷新? [英] How to tell OkHttpClient to ignore cache and force refresh from server?

问题描述

在我的Android应用程序中，我将Retrofit与OkHttpClient一起使用，并启用了缓存以访问某些API.我们的某些API有时会返回空数据.我们在应用程序中提供了一个刷新"按钮，供客户端从特定的API重新加载数据.

In my android application, I am using Retrofit with OkHttpClient with caching enabled to access some APIs. Some of our APIs sometimes return empty data. We provide a "Refresh" button in the app for the client to reload data from a specific API.

如何告诉OkHttpClient特定请求应忽略缓存的条目.或者，是否存在删除与单个请求相对应的缓存响应的机制?

How do I tell OkHttpClient that a specific request should ignore the cached entry. Alternatively, is there a mechanism to delete the cached response corresponding to a single request?

我看到Cache.remove(request)方法，但是它被标记为私有.

I see Cache.remove(request) method but it is marked as private.

推荐答案

正如Jake Wharton在问题中所建议的，这样做可以忽略缓存:

As Jake Wharton suggested in issues, do this to ignore the cache:

request.setCacheControl(CacheControl.FORCE_NETWORK);
