這篇文章主要介紹了微信公眾平臺開發多客服的示例分析,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
在新的微信協議中,開發模式也可以接入客服系統。 開發者如果需要讓用戶使用客服系統,需要在接收到用戶發送的消息時,返回一個MsgType為transfer_customer_service的消息,微信服務器在收到這條消息時,會把用戶這次發送的和以后一段時間內發送的消息轉發客服系統。
返回的消息舉例如下
<xml> <ToUserName><![CDATA[touser]]></ToUserName> <FromUserName><![CDATA[fromuser]]></FromUserName> <CreateTime>1399197672</CreateTime> <MsgType><![CDATA[transfer_customer_service]]></MsgType> </xml>
該消息的實現如下
//回復多客服消息 private function transmitService($object) { $xmlTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[transfer_customer_service]]></MsgType> </xml>"; $result = sprintf($xmlTpl, $object->FromUserName, $object->ToUserName, time()); return $result; }
一般情況下,用戶想要咨詢問題是,經常會問“你好”,“在嗎”,這樣的問題。
我們以這些詞為觸發關鍵詞,當用戶發送的文本消息內容中包含這些詞的時候,就返回多客服消息給用戶(用戶在微信端感覺不到任何內容,但微信公眾賬號會將用戶本次及以后一段時間的消息都轉發到客服)。
實現代碼如下:
//接收文本消息 private function receiveText($object) { $keyword = trim($object->Content); if (strstr($keyword, "投訴") || strstr($keyword, "你好") || strstr($keyword, "在嗎")){ $result = $this->transmitService($object); } return $result; }

".$log_content."\r\n", FILE_APPEND); } } } ?>
1. 經測試,在自定義菜單中返回多客服消息,無法讓用戶進入多客服狀態。
2. 使用多客服消息后,后續所有消息在一段時間內都將作為客服消息轉發,原來的開發模式下的自動回復都將失效!!!
