代码中运用到两个自定义函数 文末会展示出来（TP5开发）

函数中会运用到数据库 文末也会展示出数据库结构

废话不多 直接上代码

    protected $encodingAesKey = '';//创建平台时填写的公众号消息加解密Key
    protected $token = '';//创建平台时填写的公众号消息校验Token
    protected $appId = '';//公众号第三方平台AppID
    protected $appSecret = '';//公众号第三方平台appSecret
    protected $component_access_token;

//获取component_access_token
    protected function component_access_token()
    {
        $component_access_token = C('component_access_token',false);

        if(is_array($component_access_token) && !empty($component_access_token))
        {
            $time = $component_access_token['create_time'] +7000;
            if($time > time())
            {
                   $this->component_access_token = $component_access_token['v'];
                   return $component_access_token['v'];
            }
        }
        $url = 'https://api.weixin.qq.com/cgi-bin/component/api_component_token';
        $param ['component_appid'] = $this->appId;
        $param ['component_appsecret'] = $this->appSecret;
        $param ['component_verify_ticket'] = C('ComponentVerifyTicket');
        $post_data = json_encode($param);

        $data = $this->postJson($url, $post_data );

        F('component_access_token',$data['component_access_token']);
        return $this->component_access_token();

    }

运用到的函数 C 和 F

/**
 * 写入配置
 * @param $key
 * @param $value
 * @return int|string
 */
function F($key,$value)
{
    $data['v']= $value;
    $data['create_time'] = time();
    $where['k'] = $key;
     Db::table('issue_config')->where($where)->delete();
    $data['k'] = $key;
    $res = Db::table('issue_config')->insertGetId($data);
    return $res;
}

/**
 * 获取配置
 * @param $key
 * @return mixed
 */
function C($key,$flag = true)
{
    $where['k'] = $key;
    if($flag)
    {
        $res = Db::table('issue_config')->where($where)->value('v','');
    }else{
        $res = Db::table('issue_config')->where($where)->find();
    }
    return $res;
}

函数中用到的数据库：

CREATE TABLE `issue_config` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `k` varchar(255) DEFAULT NULL,
  `v` text,
  `create_time` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=181 DEFAULT CHARSET=utf8;
