【fastadmin】利用后台清除缓存按钮，来清除自定义的缓存

业务处

if (!function_exists('get_shopro_config')) {
    function get_shopro_config($name, $field)
    {
        $cache_key = 'shopro_config_' . $name . '_' . $field;
        $cache_data = cache($cache_key);
        if (!empty($cache_data)) return $cache_data;
        $value = \think\Db::name('shopro_config')->where(['name' => $name])->value('value');
        if (empty($value)) {
            $config_value = '';
        } else {
            $value_arr = json_decode($value, true);
            if (!empty($value_arr[$field])) {
                $config_value = $value_arr[$field];
            } else {
                $config_value = '';
            }
        }
        \think\Cache::tag('shopro_config')->set($cache_key, $config_value, 3600);
        return $config_value;
    }
}

代码 \think\Cache::tag('shopro_config')->set($cache_key, $config_value, 3600);
对缓存进行设置标签，然后利用tp框架清除指定的标签缓存。

后台

在application/admin/controller/Ajax.php文件修改

 /**
     * 清空系统缓存
     */
    public function wipecache()
    {
        try {
            $type = $this->request->request("type");
            switch ($type) {
                case 'all':
                    // no break
                    \think\Cache::clear('shopro_config');

代码 \think\Cache::clear('shopro_config');
