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 /* 方倍工作室 CopyRight 2014 All Rights Reserved */ 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 = $GLOBALS["HTTP_RAW_POST_DATA"]; if (!empty($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; } $this->logger("T ".$result); echo $result; }else { echo ""; exit; } } //接收事件消息 private function receiveEvent($object) { switch ($object->Event) { case "subscribe": $content[] = array("Title" =>"欢迎关注方倍工作室", "Description" =>"使用方法:\n1.发送快递单号,例如6367532560,可查询快递详情", "PicUrl" =>"http://www.3856.cc/weixin/weixin/logo.jpg", "Url" =>""); 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。

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
