微信第三方平台开发详解之代小程序开发 redis

申请第三方平台，这个很简单直接按照提示填写，下面的受权事件接收URL中获取的component_verify_ticket是会过时的，因此不要只获取一次，缓存起来每10分钟会发送一次，每1小时会更新一次。数据库

附上个人获取component_verify_ticket的代码：我是缓存和数据库都保存了json

微信有提供wxBizMsgCrypt.php加解密核心代码小程序

/**

public function sysMessage()

$wxComponentTicketModel = new \app\diuber\model\WxComponentTicket();

$encodingAesKey = $this->encodingAesKey;

$encryptMsg = file_get_contents('php://input', 'r');

libxml_disable_entity_loader(true);
$result = json_decode(json_encode(simplexml_load_string($encryptMsg, 'SimpleXMLElement', LIBXML_NOCDATA)), true);

if(config('redis_set')['use_status']){
$redis = $wxComponentTicketModel->initializeRedis();
$redis->set('wx_component_verify_ticket_xml',$encryptMsg);
}

$pc = new \WXBizMsgCrypt($token, $encodingAesKey, $appId);

公众号消息与事件接收URL，直接上代码：微信

这个方法处理3中不一样的事件推送，app

1.MsgType为text类型，而且Content信息为‘QUERY_AUTH_CODE：xxxxxxxxx’：须要经过接口’https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=xxx ’POST回复过去。

2.MsgType为text类型，而且Content信息为‘TESTCOMPONENT_MSG_TYPE_TEXT’：须要把Content信息改成‘TESTCOMPONENT_MSG_TYPE_TEXT_callback’而后加密return

3.MsgType为event类型：须要注意的是当MsgType为event类型时是没有Content信息的会增长一个Event的字段，这里只要获取到Event而后在后面加上‘from_callback’保存为Content字段信息，统一加密return。

具体逻辑看代码
