其实微信公众平台的多客服功能已经出来好久了,并且一出来的时候我就已经为自己的公众号实现了,原本以为大家都已经会了,但是今天还是有人问起这个多客服功能怎么使用,我找了下网上也没什么好的教程,今天我就给大家发一篇比较简单易懂的教程吧!
在这篇微信公众平台开发教程中,我们将介绍如何使用开发模式实现多客服系统。
一、回复多客服消息
在新的微信协议中,开发模式也可以接入客服系统。 开发者如果需要让用户使用客服系统,需要在接收到用户发送的消息时,返回一个msgtype为transfer_customer_service的消息,微信服务器在收到这条消息时,会把用户这次发送的和以后一段时间内发送的消息转发客服系统。
返回的消息举例如下
<xml> <tousername><![cdata[touser]]></tousername> <fromusername><![cdata[fromuser]]></fromusername> <createtime>1399197672</createtime> <msgtype><![cdata[transfer_customer_service]]></msgtype> </xml>
该消息的实现如下(以方倍工作室的微信公众平台php sdk为基础)
//回复多客服消息
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 $result;
}
二、触发多客服会话
一般情况下,用户想要咨询问题是,经常会问“你好”,“在吗”,这样的问题。
我们以这些词为触发关键词,当用户发送的文本消息内容中包含这些词的时候,就返回多客服消息给用户(用户在微信端感觉不到任何内容,但微信公众账号会将用户本次及以后一段时间的消息都转发到客服)。
实现代码如下:
//接收文本消息
private function receivetext($object)
{
$keyword = trim($object->content);
if (strstr($keyword, "投诉") || strstr($keyword, "你好") || strstr($keyword, "在吗")){
$result = $this->transmitservice($object);
}
return $result;
}

本段代码经过测试,在自定义菜单中返回多客服消息,无法让用户进入多客服状态,使用多客服消息后,后续所有消息在一段时间内都将作为客服消息转发,原来的开发模式下的自动回复都将失效。
