How to Use the WeChat public platform development mode to implement multi-Customer Service _ php instances

In fact, the multiple customer service functions of the public platform have been available for a long time, and I have already implemented them for my own public account. I thought everyone would have done it, but today someone asked me how to use this multi-customer service function. I found no good tutorials on the offline network, today, I will send you a simple and easy-to-understand tutorial. In fact, many customer service functions of the public platform have been available for a long time, when I came out, I had already implemented my own public account. I thought everyone would have done it. But today someone asked me how to use this multi-customer service function, I found no good tutorials on the offline network. Today I will send you a simple and easy-to-understand tutorial!

In this public platform development tutorial, we will introduce how to use the development mode to implement a multi-customer service system.

I. Reply to multiple customer service messages

In the new protocol, the development mode can also be connected to the customer service system. If the developer wants the user to use the customer service system, a message with the MsgType transfer_customer_service is returned when the user receives the message. When the server receives the message, the messages sent by the user this time and later will be forwarded to the customer service system.

The returned message is as follows:

   
  touser
    
  fromuser
    
  
   1399197672
    
  transfer_customer_service
  
  

The message is implemented as follows (based on the public platform php sdk of fangtimes studio)

// Reply to multiple customer service messages private function transmitService ($ object) {$ xmlTpl ="
 
  %s
  
  %s
  
  
   
% S
  
  transfer_customer_service
  
 "; $ Result = sprintf ($ xmlTpl, $ object-> FromUserName, $ object-> ToUserName, time (); return $ result ;}

Ii. Trigger multi-Customer Service Sessions

Generally, the user may ask "hello" or "Are you there" questions.

We use these words as trigger keywords. When the text message content sent by the user contains these words, multiple customer service messages are returned to the user (the user does not feel any content at the end, however, the public account will forward the user's messages for this time and a period later to the customer service ).

The implementation code is as follows:

// Receive text message private function receiveText ($ object) {$ keyword = trim ($ object-> Content); if (strstr ($ keyword, "complaint ") | strstr ($ keyword, "") | strstr ($ keyword, "") {$ result = $ this-> transmitService ($ object );} return $ result ;}

"". $ log_content. "\ r \ n", FILE_APPEND) ;}}?>

After this code is tested, multiple customer service messages are returned in the custom menu, so that users cannot enter the multi-Customer Service Status. After Multiple customer service messages are used, all subsequent messages will be forwarded as customer service messages within a period of time, and automatic replies in the original development mode will become invalid.
