WeChat public platform development interface (3) and Wechat development interface

Public platform development interface (3): Development Interface

I haven't written any article about the public account for a long time, and my research has come to an end, but I still share the complete code of some of my only functions. Hope everyone can make progress together:

 
 

  
  
<? Php
  
  
Define ("TOKEN", "weixin ");
  
  
$ WechatObj = new wechatCallbackapiTest ();
  
  
$ WechatObj-> weixin_run ();
  
  
 
  
  
Class wechatCallbackapiTest {
  
  
 
  
  
Private $ fromUsername;
  
  
Private $ toUsername;
  
  
Private $ times;
  
  
Private $ keyword;
  
  
Private $ MsgType;
  
  
 
  
  
Public function responseMsg (){
  
  
$ PostStr = $ GLOBALS ["HTTP_RAW_POST_DATA"];
  
  
If (! Empty ($ postStr )){
  
  
$ PostObj = simplexml_load_string ($ postStr, 'simplexmlelement', LIBXML_NOCDATA );
  
  
$ This-> fromUsername = $ postObj-> FromUserName;
  
  
$ This-> toUsername = $ postObj-> ToUserName;
  
  
$ This-> keyword = trim ($ postObj-> Content );
  
  
$ This-> time = time ();
  
  
$ This-> MsgType = $ postObj-> MsgType;
  
  
} Else {
  
  
Echo "Pay attention to <a href = 'HTTP: // {$ _ SERVER ['HTTP _ host']} '> http: // {$ _ SERVER ['HTTP _ host']} </a>, thanks! ";
  
  
Exit;
  
  
}
  
  
}
  
  
 
  
  
Public function weixin_run (){
  
  
$ This-> responseMsg ();
  
  
If ($ this-> MsgType! = 'Event') {// attention
  
  
$ Data = $ this-> getData ();
  
  
$ This-> fun_xml ("news", $ data, count ($ data ));
  
  
} Else {
  
  
$ Data = $ this-> getWelData ();
  
  
$ This-> fun_xml ("text", $ data, 1 );
  
  
}
  
  
}
  
  
 
  
  
// Type: text type, news text type
  
  
// Text, array (content), array (ID)
  
  
// News, array (title, Introduction, image, hyperlink),... smaller than 10), number of items
  
  
Private function fun_xml ($ type, $ value_arr, $ count ){
  
  
$ Con = "<xml>
  
  
<ToUserName> <! [CDATA [{$ this-> fromUsername}]> </ToUserName>
  
  
<FromUserName> <! [CDATA [{$ this-> toUsername}]> </FromUserName>
  
  
<CreateTime >{$ this-> times} </CreateTime>
  
  
<MsgType> <! [CDATA [{$ type}]> </MsgType> ";
  
  

  
  
Switch ($ type ){
  
  
Case "text ":
  
  
$ Con. = "<Content> <! [CDATA [$ value_arr]> </Content> ";
  
  
Break;
  
  
Case "news ":
  
  
$ Con. = "<ArticleCount >{$ count} </ArticleCount>
  
  
<Articles> ";
  
  
Foreach ($ value_arr as $ key => $ v ){
  
  
$ Con. = "<item>
  
  
<Title> <! [CDATA [{$ v [0]}]> </Title>
  
  
<Description> <! [CDATA [{$ v [1]}]> </Description>
  
  
<PicUrl> <! [CDATA [{$ v [2]}]> </PicUrl>
  
  
<Url> <! [CDATA [{$ v [3]}]> </Url>
  
  
</Item> ";
  
  
}
  
  
$ Con. = "</Articles> ";
  
  
Break;
  
  
}
  
  
Echo $ con. "</xml> ";
  
  
}
  
  
 
  
  
Private function getData (){
  
  
// The database queries an article by keyword
  
  
 
  
  
//............
  
  
//............
  
  
 
  
  
// Returns an array of article results
  
  
Return $ data;
  
  
}
  
  
 
  
  
Private function getWelData (){
  
  
$ Data = "thank you for choosing AndyYang personal blog assistant. \ R \ n ".
  
  
"Reply [1] Back to two latest articles \ r \ n ".
  
  
"Reply [2] Return two popular articles \ r \ n ".
  
  
"Reply [3] Return two hot comments \ r \ n ".
  
  
"Reply [4] Back to two latest technical articles \ r \ n ".
  
  
"Reply [5] Back to two latest writing articles \ r \ n ".
  
  
"Reply to two other articles that return the search keyword \ r \ n ".
  
  
"For more information, see <a href = 'HTTP: // www.webyang.net/mobile.php'> www.webyang.net </a>. Thank you for your support ~ ";
  
  
;
  
  
Return $ data;
  
  
}
  
  

  
  
}
 
 

To be honest, I really want to get a service number for fun. The custom menu has no technical content, but the only service of the service number, such as payment, is worth trying...

I also hope that you can use the "webyangnet" support code.

What are the areas for public platform interface development?

I have this course and can send it to you.
Highlight 1: Message Interaction

The message interface of the public platform provides developers with the ability to exchange messages with users. For a public account that successfully accesses the message interface, when a user sends a message to the public account, the public platform server uses an http request to push messages to the accessed URL, A third-party server can reply to a message through a response packet.

Highlight 2: New Mobile Service Forms

Open the public platform of the API, so that the public account has a larger space to play. Currently, querying bank balances, translating English words, booking hotels, booking movie tickets, Food Recommendations, dressing recommendations, and so on has sprung up to address the needs of different users.

How can I upload an application for interface development on a public platform to make the port respond?

Haha. If you do not understand this, you must rely on others to develop and learn more. Follow our public account binguome
