小編給大家分享一下微信公眾平臺(tái)開發(fā)之多客服的示例分析，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！
一、回復(fù)多客服消息
在新的微信協(xié)議中，開發(fā)模式也可以接入客服系統(tǒng)。 開發(fā)者如果需要讓用戶使用客服系統(tǒng)，需要在接收到用戶發(fā)送的消息時(shí)，返回一個(gè)MsgType為transfer_customer_service的消息，微信服務(wù)器在收到這條消息時(shí)，會(huì)把用戶這次發(fā)送的和以后一段時(shí)間內(nèi)發(fā)送的消息轉(zhuǎn)發(fā)客服系統(tǒng)。
返回的消息舉例如下
1399197672
該消息的實(shí)現(xiàn)如下
重慶分公司
重慶分公司
//回復(fù)多客服消息
private function transmitService($object)
{
$xmlTpl = "
%s
";
$result = sprintf($xmlTpl, $object->FromUserName, $object->ToUserName, time());
return $result;
}二、觸發(fā)多客服會(huì)話
一般情況下，用戶想要咨詢問題是，經(jīng)常會(huì)問“你好”，“在嗎”，這樣的問題。
我們以這些詞為觸發(fā)關(guān)鍵詞，當(dāng)用戶發(fā)送的文本消息內(nèi)容中包含這些詞的時(shí)候，就返回多客服消息給用戶（用戶在微信端感覺不到任何內(nèi)容，但微信公眾賬號會(huì)將用戶本次及以后一段時(shí)間的消息都轉(zhuǎn)發(fā)到客服）。
實(shí)現(xiàn)代碼如下：
//接收文本消息
private function receiveText($object)
{
$keyword = trim($object->Content);
if (strstr($keyword, "投訴") || strstr($keyword, "你好") || strstr($keyword, "在嗎")){
$result = $this->transmitService($object);
}
return $result;
}三、完整代碼
responseMsg();
}else{
$wechatObj->valid();
}
class wechatCallbackapiTest
{
//驗(yàn)證消息
public function valid()
{
$echoStr = $_GET["echostr"];
if($this->checkSignature()){
echo $echoStr;
exit;
}
}
//檢查簽名
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;
}
}
//響應(yīng)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" =>"歡迎關(guān)注方倍工作室", "Description" =>"使用方法：\n1.發(fā)送快遞單號,例如6367532560,可查詢快遞詳情", "PicUrl" =>"/tupian/20230522/404.html
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 == "時(shí)間" || $keyword == "測試"){
$content = date("Y-m-d H:i:s",time());
$result = $this->transmitText($object, $content);
}
//觸發(fā)多客服模式
else if (strstr($keyword, "您好") || strstr($keyword, "你好") || strstr($keyword, "在嗎") || strstr($keyword, "有人嗎")){
$result = $this->transmitService($object);
return $result;
}
return $result;
}
private function transmitText($object, $content)
{
$textTpl = "
%s
";
$result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content);
return $result;
}
private function transmitNews($object, $newsArray)
{
if(!is_array($newsArray)){
return;
}
$itemTpl = " -
<![CDATA[%s]]>
";
$item_str = "";
foreach ($newsArray as $item){
$item_str .= sprintf($itemTpl, $item['Title'], $item['Description'], $item['PicUrl'], $item['Url']);
}
$newsTpl = "
%s
%s
$item_str
";
$result = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray));
return $result;
}
private function transmitMusic($object, $musicArray)
{
$itemTpl = "
<![CDATA[%s]]>
";
$item_str = sprintf($itemTpl, $musicArray['Title'], $musicArray['Description'], $musicArray['MusicUrl'], $musicArray['HQMusicUrl']);
$textTpl = "
%s
";
$result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time());
return $result;
}
//回復(fù)多客服消息
private function transmitService($object)
{
$xmlTpl = "
%s
";
$result = sprintf($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);
}
}
}
?>四、其他注意事項(xiàng)
1. 經(jīng)測試，在自定義菜單中返回多客服消息，無法讓用戶進(jìn)入多客服狀態(tài)。
2. 使用多客服消息后，后續(xù)所有消息在一段時(shí)間內(nèi)都將作為客服消息轉(zhuǎn)發(fā)，原來的開發(fā)模式下的自動(dòng)回復(fù)都將失效?。?！
