Open platform-third-party platform-implement business on behalf of Mini Program, access to cache is incorrect?

Open platform-third-party platform-implements business on behalf of Mini Program, but the cache is not obtained correctly?
Environment + laravel5.5 + redis

I set the redis cache in the env file, and make sure there is no problem with the cache by looking at the cache. In the getTicket () function of the EasyWeChatOpenPlatformAuth VerifyTicket class of sdk, $cached = $this- > getCache ()-> get ($this- > getCacheKey ()) I feel that the cache is a file cache, so I rewrote sdk $cached = cache ($this- > getCacheKey ()), component_verify_ticket). Why can"t I get it from redis?
