為什么80%的碼農都做不了架構師？>>> ??

這部分調試了很久，因為在新用戶掃描了好友分享的二維碼之后需要分發兩條消息，一條是自動推送給當前用戶歡迎的消息，另一條是推送給二維碼主人的消息。調試了很久都不能同時分發（也許是我的邏輯或者方法有問題吧【尷尬臉】）。后來去谷歌了一下，好像不能分發兩條或者多條消息，只能分發一條消息，所以這部分需要用到客服消息接口。

不多說，先看代碼

首先要去配置公眾號的服務器配置，用于接收微信的推送消息 參考文檔（https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421140543）
注意：在啟用了服務器配置過后，原有的自定義菜單功能等將不能使用了，所以得編寫菜單功能，
參考文檔（https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141013）

public function customMenu(){//組裝菜單數據$data = ' {"button":[{ "type":"click","name":"今日歌曲","key":"V1001_TODAY_MUSIC"},{"name":"菜單","sub_button":[{ "type":"view","name":"搜索","url":"http://www.soso.com/"},{"type":"miniprogram","name":"wxa","url":"http://mp.weixin.qq.com","appid":"wx286b93c14bbf93aa","pagepath":"pages/lunar/index"},{"type":"click","name":"贊一下我們","key":"V1001_GOOD"}]}]}';$access_token = $this->getWeiXinToken();$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=$access_token";$getData = $this->httpPostFunc($url, $data, 'POST');var_dump($getData);

驗證消息是否來自微信后臺（主要是驗證echostr參數）

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'));//這里是框架自帶的緩存}/*** 參數signature、nonce、timestamp驗證消息是否來自微信后臺，驗證成功時返回echostr給微信后臺服務器，已確定接口配置成功*/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 $echoStr;exit;}}/*** 驗證簽名* @return bool*/private function checkSignature(){$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($keyArray) != 1) {//掃好友分享的二維碼關注,未關注者關注后推送事件$getContent = $this->getAndSaveUserInfo($postObj, $keyArray[1]);//拿到用戶的openId和userId,再拿到用戶的詳細信息，并將個人微信信息保存至數據庫}switch ($TYPE){case "text":$resultStr = $this->receiveText($postObj);break;case "event":if($postObj->EventKey == 'V1001_wap_create_1'){//點擊生成二維碼圖片$resultStr = $this->receiveText($postObj);}else{$resultStr = $this->receiveEvent($postObj);}if($getContent){//是否新關注者，并調用客服接口給二維碼主人發送消息$this->replyCustomer($getContent['openId'], $getContent['content']);}break;default:$resultStr = "";break;}echo $resultStr;}else {echo "";exit;}}

4.在方法receiveText和receiveEvent中主要是組裝xml數據，主要請參考文檔（https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421140453）
方法replyCustomer主要是給二維碼主人或者其他人發消息，參考文檔（https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421140547）

private function replyCustomer($touser,$content){$access_token = $this->getWeiXinToken();;$data = '{"touser":"'.$touser.'","msgtype":"text","text":{"content":"'.$content.'"}}';$url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$access_token ;$result = $this->httpPostFunc($url, $data, 'POST');$data = json_decode($result);return $data;}

這是這個方法發的消息
