我按照文档写了两个函数

if (! function_exists('database_set_cache'))
{
    function database_set_cache($key, $value, $lifetime)
    {
        $cache = \App\Models\Admin\WxWorkCache::where('key',$key)->first();
        if($cache === null)
        {
            $newCache = new \App\Models\Admin\WxWorkCache;
            $newCache->key = $key;
            $newCache->body = $value;
            $newCache->lifetime = $lifetime;
            $newCache->save();
            return $newCache;
        }
        else
        {
            $cache->key = $key;
            $cache->body = $value;
            $cache->lifetime = $lifetime;
            $cache->save();
            return $cache;
        }
    }
}

if(! function_exists('database_get_cache'))
{
    function database_get_cache($key)
    {
        $cache = \App\Models\Admin\WxWorkCache::where('key',$key)->first();
        return $cache->body;
    }
}

请问一下,$lifetime得到的是6400,那么cache类是怎么判断token过期的呢?

cache类和token没有关系,cache类在这里只是负责缓存写入和读取,在这里只是把token存到了缓存中。自定义缓存的setter和getter函数写成匿名函数就可以了,这样的话缓存的读取和写入就会使用你自定义的形式。

我现在是写了一个middleware 把缓存方法写在了里头

<?php

namespace App\Http\Middleware;

use Closure;

class WxWorkCacheMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        \Stoneworld\Wechat\Cache::setter(function($key,$value,$lifetime){
            return $this->database_set_cache($key,$value,$lifetime);
        });
        \Stoneworld\Wechat\Cache::getter(function($key){
            return $this->database_get_cache($key);
        });
        return $next($request);
    }

    private function database_set_cache($key, $value, $lifetime)
    {
        $cache = \App\Models\Admin\WxWorkCache::where('key',$key)->first();
        if($cache === null)
        {
            $newCache = new \App\Models\Admin\WxWorkCache;
            $newCache->key = $key;
            $newCache->body = $value;
            $newCache->lifetime = $lifetime;
            $newCache->save();
            return $newCache;
        }
        else
        {
            $cache->key = $key;
            $cache->body = $value;
            $cache->lifetime = $lifetime;
            $cache->save();
            return $cache;
        }
    }

    private function database_get_cache($key)
    {
        $cache = \App\Models\Admin\WxWorkCache::where('key',$key)->first();
        if($cache === null)
        {
            return null;
        }
        elseif($cache->updated_at->getTimestamp() + $cache->lifetime > time())
        {
            return $cache->body;
        }
        else
        {
            return null;
        }
    }
}

但是我觉得还是没有安正超的公众号sdk的自定义缓存用起来方便,安正超的是直接在options里定义的cache

这个包是基于超哥的sdk2.0改写的,所以和现在超哥的3.0之后的肯定都不一样的。
