为什么80%的码农都做不了架构师？>>>
这部分调试了很久，因为在新用户扫描了好友分享的二维码之后需要分发两条消息，一条是自动推送给当前用户欢迎的消息，另一条是推送给二维码主人的消息。调试了很久都不能同时分发（也许是我的逻辑或者方法有问题吧【尴尬脸】）。后来去谷歌了一下，好像不能分发两条或者多条消息，只能分发一条消息，所以这部分需要用到客服消息接口。
不多说，先看代码
首先要去配置公众号的服务器配置，用于接收微信的推送消息 参考文档（https://mp./wiki?t=resource/res_main&id=mp1421140543）
注意：在启用了服务器配置过后，原有的自定义菜单功能等将不能使用了，所以得编写菜单功能，
参考文档（https://mp./wiki?t=resource/res_main&id=mp1421141013）
public function customMenu(){//组装菜单数据$data = ' {"button":[{"type":"click","name":"今日歌曲","key":"V1001_TODAY_MUSIC"},{"name":"菜单","sub_button":[{"type":"view","name":"搜索","url":"/"},{"type":"miniprogram","name":"wxa","url":"http://mp.","appid":"wx286b93c14bbf93aa","pagepath":"pages/lunar/index"},{"type":"click","name":"赞一下我们","key":"V1001_GOOD"}]}]}';$access_token = $this->getWeiXinToken();$url = "https://api./cgi-bin/menu/create?access_token=$access_token";$getData = $this->httpPostFunc($url, $data, 'POST');var_dump($getData);
验证消息是否来自微信后台（主要是验证echostr参数）
private $appId;private $appSecret;/*** weChat constructor.*/public function __construct() {parent::__construct();$this->appId = 'xxxxxxx';$this->appSecret = 'xxxxxxxx';$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));//这里是框架自带的缓存}/*** 参数signature、nonce、timestamp验证消息是否来自微信后台，验证成功时返回echostr给微信后台服务器，已确定接口配置成功*/public function index(){define("TOKEN", "xxxx");$echostr = $this->input->get('echostr',true);if (!$echostr) {$this->responseMsg();}else{$this->valid();}}private function valid(){$echoStr = $_GET["echostr"];if($this->checkSignature()){echo $echoStr;exit;}}/*** 验证签名* @return bool*/private function checkSignature(){$signature = $_GET["signature"];$timestamp = $_GET["timestamp"];$nonce = $_GET["nonce"];$token = TOKEN;$tmpArr = array($token, $timestamp, $nonce);sort($tmpArr);$tmpStr = implode( $tmpArr );$tmpStr = sha1( $tmpStr );if( $tmpStr == $signature ){return true;}else{return false;}}
3.消息推送方法responseMsg，
private function responseMsg(){$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];if (!empty($postStr)){$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);$TYPE = trim($postObj->MsgType);$EventKey = trim((string)$postObj->EventKey);$keyArray = explode("_", $EventKey);if (count($keyArray) && count($keyArray) != 1) {//扫好友分享的二维码关注,未关注者关注后推送事件$getContent = $this->getAndSaveUserInfo($postObj, $keyArray[1]);//拿到用户的openId和userId,再拿到用户的详细信息，并将个人微信信息保存至数据库}switch ($TYPE){case "text":$resultStr = $this->receiveText($postObj);break;case "event":if($postObj->EventKey == 'V1001_wap_create_1'){//点击生成二维码图片$resultStr = $this->receiveText($postObj);}else{$resultStr = $this->receiveEvent($postObj);}if($getContent){//是否新关注者，并调用客服接口给二维码主人发送消息$this->replyCustomer($getContent['openId'], $getContent['content']);}break;default:$resultStr = "";break;}echo $resultStr;}else {echo "";exit;}}
4.在方法receiveText和receiveEvent中主要是组装xml数据，主要请参考文档（https://mp./wiki?t=resource/res_main&id=mp1421140453）
方法replyCustomer主要是给二维码主人或者其他人发消息，参考文档（https://mp./wiki?t=resource/res_main&id=mp1421140547）
private function replyCustomer($touser,$content){$access_token = $this->getWeiXinToken();;$data = '{"touser":"'.$touser.'","msgtype":"text","text":{"content":"'.$content.'"}}';$url = "https://api./cgi-bin/message/custom/send?access_token=".$access_token ;$result = $this->httpPostFunc($url, $data, 'POST');$data = json_decode($result);return $data;}
这是这个方法发的消息
