一、安装easyWeChat
easyWeChat 文档 ：
/docs/4.1/overview
使用composer下载
composer require overtrue/wechat:~4.0 -vvv
或者直接下载源码放到 extend下
二、引入
use EasyWeChat\Factory;
easywechat配置： 根据需要设置
$config=[/*** Debug 模式，bool 值：true/false** 当值为 false 时，所有的日志都不会记录*/'debug' => false,/*** 账号基本信息，请从微信公众平台/开放平台获取*/'app_id' => 'wxc0330dcea9e9a', // AppID'secret' => 'c96af0236069b',// AppSecret'token' => 'mytest',// Token'aes_key' => 'i0MbeyhX8lp5tlL7hRCjbLo2GdVNqCD3h7DcmFJmnGU','response_type' => 'array',/*** 日志配置** level: 日志级别, 可选为：* debug/info/notice/warning/error/critical/alert/emergency* permission：日志文件权限(可选)，默认为null（若为null值,monolog会取0644）* file：日志文件位置(绝对路径!!!)，要求可写权限*/'log' => ['level'=> 'debug','permission' => 0777,'file' => '/tmp/easywechat.log',],/*** OAuth 配置** scopes：公众平台（snsapi_userinfo / snsapi_base），开放平台：snsapi_login* callback：OAuth授权完成后的回调页地址*/'oauth' => ['scopes' => ['snsapi_userinfo'],'callback' => '/user/wechat/oauth_callback',],/*** 微信支付*/'payment' => ['merchant_id' => '135*****602','key'=> '80b8682*****8fdac7784','cert_path'=> ROOT_PATH . 'public/certs/wechat/apiclient_cert.pem', // XXX: 绝对路径！！！！'key_path' => ROOT_PATH . 'public/certs/wechat/apiclient_key.pem',// XXX: 绝对路径！！！！'notify_url' => 'http://*******/notify/wxpay',],/*** Guzzle 全局设置** 更多请参考： /en/latest/request-options.html*/'guzzle' => ['timeout' => 3.0, // 超时时间（秒）'verify' => false, // 关掉 SSL 认证（强烈不建议！！！）],];return $config;}
三、接入步骤
1.首次接入验证
此处用数据库保存的token对微信提交的参数进行验签比对，如果不需要验证token验证的话直接原样输出
echostr 即可接入
//微信首次接入验证if (!empty($_GET['echostr']) && $this->checkSignature($_W['config']['token'])) {header('content-type:text');echo $_GET['echostr'];exit;}/** 接入验签*/private function checkSignature($token){$signature = $_GET["signature"];$timestamp = $_GET["timestamp"];$nonce = $_GET["nonce"];$tmpArr = array($token, $timestamp, $nonce);sort($tmpArr);$tmpStr = implode($tmpArr);$tmpStr = sha1($tmpStr);if ($tmpStr == $signature) {return true;} else {return false;}}
2.消息处理
根据消息类型交给不同模块去处理，只回复字符串的话直接return就好，其他类型消息需要进一步装配，详细参见文档。
public function index(Request $request){global $_W;$app = Factory::officialAccount($_W['config']);$app->server->push(function ($message) {global $_W;$memberModel = new Members();$_W['user'] = $memberModel->getInfoByOpenidAndUniacid($message['FromUserName'], $_W['uniacid']);//用户信息// $message['FromUserName'] // 用户的 openid// $message['MsgType'] // 消息类型：event, text....$handler = new MessageHandler($message);switch ($message['MsgType']) {case 'event'://return '收到事件消息';return $handler->eventHandler($message['FromUserName']);break;case 'text'://return '收到文字消息';return $handler->textHandler();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';return $handler->test();break;case 'link':return '收到链接消息';break;case 'file':return '收到文件消息';// ... 其它消息default:return '收到其它消息';break;}});$response = $app->server->serve();$response->send();}
messageHandler
具体处理各种消息，
class MessageHandler{/** 消息对象*/private $message;public function __construct($message){$this->message = $message;}/** 事件响应函数*/public function eventHandler($openid){// $message['FromUserName'] // 用户的 openid// $message['MsgType'] // 消息类型：event, text....global $_W;switch ($this->message['Event']) {//关注事件case 'subscribe':return $this->focusEvent($openid, $_W['auid']);break;//取消关注事件case 'unsubscribe':return '取关';break;//点击事件case 'CLICK':if ($this->message['EventKey'] == 'sign') {$res = $this->signEvent($openid);$SignModel = new Signs();$SignModel->SignEventFun($openid,$_W['auid']);return $res;}return '取关';break;default:return '收到其它消息';break;}}}
发送模板消息
$app = Factory::officialAccount($_W['config']);$res = $app->template_message->send(['touser' => 'oWsdC5tt9ZXVn8YkK2ZvsHDGw','template_id' => '2ujQBy5j1od8JzKfuvZvhTzX','url' => '','data' => ['key1' => 'VALUE','key2' => 'VALUE2',],]);
图文消息
use EasyWeChat\Kernel\Messages\Text;use EasyWeChat\Kernel\Messages\News;use EasyWeChat\Kernel\Messages\NewsItem;$items = [new NewsItem(['title' => $replayInfo->book_name,'description' => $replayInfo->introduction,'url' => $url,'image' => $replayInfo->book_flash,]),];return new News($items);
客服消息
/*** Notes:发送模板消息* @author:xxf* Date: -06-02* Time: 15:11* @param $touser* @param $template_id* @param $url* @param $data* @param string $topcolor* @return bool* @throws \EasyWeChat\Kernel\Exceptions\InvalidArgumentException*/public function sendTplMessage($touser, $template_id, $url, $data, $topcolor = '#7B68EE'){$config= $this->config();$app = Factory::officialAccount($config);$app->template_message->send(['touser' => $touser,'template_id' => $template_id,'topcolor' => $topcolor,'url' => $url,'data' => $data,]);return true;}/*** Notes:发送客服消息* @author:xxf* Date: -06-04* Time: 14:15* @param $touser* @param $data* @return bool* @throws \EasyWeChat\Kernel\Exceptions\InvalidArgumentException* @throws \EasyWeChat\Kernel\Exceptions\RuntimeException*/public function sendMessage($touser,$msg, $url){$config= $this->config();$app = Factory::officialAccount($config);if (!empty($url)) {$msg .= '<a href=\'' . $url .
