easywechat 第三方平台授权component_verify_ticket缓存获取不到？

Question

"component_verify_ticket" does not exist in cache
这里也做过缓存了

        $app = Factory::openPlatform(config('wechat.open_platform.default'));
        $predis = app('redis')->connection()->client();
        $cache = new RedisCache($predis);
        $app->rebind('cache', $cache);
        $this->server = $app;

能收到微信传过来的ticket 就是在缓存里找不到。

Answer 1

/**
 * Get cache key.
 *
 * @return string
 */
protected function getCacheKey(): string
{
    return 'easywechat.open_platform.verify_ticket.'.$this->app['config']['app_id'];
}
