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;
- }
三、完整代码
- <?php
- /*

- */
- define("TOKEN", "weixin");
- $wechatObj = new wechatCallbackapiTest();
- if (!isset($_GET['echostr'])) {
- $wechatObj->responseMsg();
- }else{
- $wechatObj->valid();
- }
- class wechatCallbackapiTest
- {
- //验证消息
- public function valid()
- {
- $echoStr = $_GET["echostr"];
- if($this->checkSignature()){
- echo $echoStr;
- exit;
- }
- }
- //检查签名
- private function checkSignature()
- {
- $signature = $_GET["signature"];
- $timestamp = $_GET["timestamp"];
- $nonce = $_GET["nonce"];
- $token = TOKEN;
- $tmpArr = array($token, $timestamp, $nonce);
- sort($tmpArr, SORT_STRING);
- $tmpStr = implode($tmpArr);
- $tmpStr = sha1($tmpStr);
- if($tmpStr == $signature){
- return true;
- }else{
- return false;
- }
- }
- //响应消息
- public function responseMsg()
- {
- $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
- if (!emptyempty($postStr)){
- $this->logger("R ".$postStr);
- $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
- $RX_TYPE = trim($postObj->MsgType);
- switch ($RX_TYPE)
- {
- case "event":
- $result = $this->receiveEvent($postObj);
- break;
- case "text":
- $result = $this->receiveText($postObj);
- break;
- }

- echo $result;
- }else {
- echo "";
- exit;
- }
- }
- //接收事件消息
- private function receiveEvent($object)
- {
- switch ($object->Event)

- break;
- default:
- $content = "receive a new event: ".$object->Event;
- break;
- }
- if(is_array($content)){
- if (isset($content[0])){
- $result = $this->transmitNews($object, $content);
- }else if (isset($content['MusicUrl'])){
- $result = $this->transmitMusic($object, $content);
- }
- }else{
- $result = $this->transmitText($object, $content);
- }
- return $result;
- }
- //接收文本消息
- private function receiveText($object)
- {
- $keyword = trim($object->Content);
- if($keyword == "时间" || $keyword == "测试"){
- $content = date("Y-m-d H:i:s",time());
- $result = $this->transmitText($object, $content);
- }
- //触发多客服模式
- else if (strstr($keyword, "您好") || strstr($keyword, "你好") || strstr($keyword, "在吗") || strstr($keyword, "有人吗")){
- $result = $this->transmitService($object);
- return $result;
- }
- return $result;
- }
- private function transmitText($object, $content)
- {
- $textTpl = "<xml>
- <ToUserName><![CDATA[%s]]></ToUserName>
- <FromUserName><![CDATA[%s]]></FromUserName>
- <CreateTime>%s</CreateTime>
- <MsgType><![CDATA[text]]></MsgType>
- <Content><![CDATA[%s]]></Content>
- </xml>";
- $result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content);
- return $result;
- }
- private function transmitNews($object, $newsArray)
- {
- if(!is_array($newsArray)){
- return;
- }
- $itemTpl = " <item>
- <Title><![CDATA[%s]]></Title>
- <Description><![CDATA[%s]]></Description>
- <PicUrl><![CDATA[%s]]></PicUrl>
- <Url><![CDATA[%s]]></Url>
- </item>
- ";
- $item_str = "";
- foreach ($newsArray as $item){
- $item_str .= sprintf($itemTpl, $item['Title'], $item['Description'], $item['PicUrl'], $item['Url']);
- }
- $newsTpl = "<xml>
- <ToUserName><![CDATA[%s]]></ToUserName>
- <FromUserName><![CDATA[%s]]></FromUserName>
- <CreateTime>%s</CreateTime>
- <MsgType><![CDATA[news]]></MsgType>
- <Content><![CDATA[]]></Content>
- <ArticleCount>%s</ArticleCount>
- <Articles>
- $item_str</Articles>
- </xml>";
- $result = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray));
- return $result;
- }
- private function transmitMusic($object, $musicArray)
- {
- $itemTpl = "<Music>
- <Title><![CDATA[%s]]></Title>
- <Description><![CDATA[%s]]></Description>
- <MusicUrl><![CDATA[%s]]></MusicUrl>
- <HQMusicUrl><![CDATA[%s]]></HQMusicUrl>
- </Music>";
- $item_str = sprintf($itemTpl, $musicArray['Title'], $musicArray['Description'], $musicArray['MusicUrl'], $musicArray['HQMusicUrl']);
- $textTpl = "<xml>
- <ToUserName><![CDATA[%s]]></ToUserName>
- <FromUserName><![CDATA[%s]]></FromUserName>
- <CreateTime>%s</CreateTime>
- <MsgType><![CDATA[music]]></MsgType>
- $item_str
- </xml>";
- $result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time());
- return $result;
- }
- //回复多客服消息
- private function transmitService($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 $result;
- }
- private function logger($log_content)
- {
- if(isset($_SERVER['HTTP_APPNAME'])){ //SAE
- sae_set_display_errors(false);
- sae_debug($log_content);
- sae_set_display_errors(true);
- }else if($_SERVER['REMOTE_ADDR'] != "127.0.0.1"){ //LOCAL
- $max_size = 10000;
- $log_filename = "log.xml";
- if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);}
- file_put_contents($log_filename, date('H:i:s')." ".$log_content."\r\n", FILE_APPEND);
- }
- }
- }
- ?>
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。
