tp5-微信消息接收和处理

Posted 2021-03-03 艾薇-Ivy

微信后台只能填写一个服务器地址，所以 服务器验证 与 消息的接收与回复，都在这一个链接内完成交互。

一、服务器验证：配置地址可写为：http://域名/openapi/wechat/wxapi

<?php

namespace Openapi;

use ApiBase;
use EasyWeChatFactory;
use WechatOfficialAccount;

class Wechat extends Base
{
    var $wx_config = null;

    public function wxapi()
    {
        try {
            $wx_config = $this->config->wechat->toArray();
            $app = Factory::officialAccount($wx_config);
            $log = $this->logger;
            $redis = $this->redisDb;
            $app->server->push(function ($message) use ($app, $log, $redis) { //消息接收
                $openid = $message[‘FromUserName‘];
                //微信用户信息
                $user = $app->user->get($openid);
                $log->info(json_encode($message));
                $official_account = new OfficialAccount();
                $official_account->replyMessage($message,$user);
            });
            $response = $app->server->serve();
            $response->send();

        } catch (Exception $e) {
            $this->logw($e->getMessage());
        }
    }
}

 

二、消息处理

<?php
namespace Wechat;

use ComponentWechatWechat;
use PhalconDi;
use MvcDbFilter;

class OfficialAccount{

public function replyMessage($message ,$data){
        switch ($message[‘MsgType‘]) {
            case ‘event‘:
                switch ($message[‘Event‘]) {
                    case ‘subscribe‘:
                        $restaurant_id = 0;
                        $restaurant_str = $message[‘EventKey‘];
                        ....
                        //业务逻辑处理
                        break;
                    case ‘unsubscribe‘:
                        //取消关注return "您已取消关注";
                        break;
                    case ‘SCAN‘:
                        if ($message[‘EventKey‘]) {
                            $restaurant_id = 0;
                            $restaurant_arr = explode(‘_‘, $message[‘EventKey‘]);
                           ......
                        break;
                }
                return ‘欢迎关注‘;
                break;
            case ‘text‘:
                return ‘收到，但是目前没有接下来的动作‘;
                break;
            default:
                return ‘收到其它消息‘;
                break;
        }
    }
}

 三、demo

$app->server->push(function ($message) {
    switch ($message[‘MsgType‘]) {
        case ‘event‘:
            return ‘收到事件消息‘;
            break;
        case ‘text‘:
            return ‘收到文字消息‘;
            break;
        case ‘image‘:
            return ‘收到图片消息‘;
            break;
        case ‘voice‘:
            return ‘收到语音消息‘;
            break;
        case ‘video‘:
            return ‘收到视频消息‘;
            break;
        case ‘location‘:
            return ‘收到坐标消息‘;
            break;
        case ‘link‘:
            return ‘收到链接消息‘;
            break;
        case ‘file‘:
            return ‘收到文件消息‘;
        // ... 其它消息
        default:
            return ‘收到其它消息‘;
            break;
    }

    // ...
});
