Php-based methods for receiving messages, automatically determining and replying to corresponding messages, and php messages

This article describes how to receive, automatically determine, and reply to, messages developed by php. We will share this with you for your reference. The details are as follows:

The api is now powerful enough to call the content of our website or specified database at will to automatically reply to the current push message. Here we will introduce you to a development note.

Send messages 500, to test the corresponding message. The menu mode must be upgraded to the service number, or the number of subscribers exceeds.

1. All messages sent by users are received through the developer URL you submit. Here, the subscription number can be used. All messages sent are in xml format and need to be parsed. The Code is as follows:

$ Data = $ GLOBALS ["HTTP_RAW_POST_DATA"]; if (! Emptyempty ($ data) {// receives and processes the message $ xml = (array) simplexml_load_string ($ data, 'simplexmlelement', LIBXML_NOCDATA); return $ xml ;}

The response also needs to return the XML data format.

2. Actively send a message to the user, query user information, create a custom menu (now the subscription number can also be used), and some advanced functions require obtaining appid and AppSecret to get access_token.

Access_token is used by each interface except for receiving information. The length of access_token is 7200 milliseconds and needs to be retrieved again.

For more information, see: http://mp.weixin.qq.com/wiki/index.php? Title = % E9 % A6 % 96% E9 % A1 % B5.

Currently, I have implemented the following functions: receiving messages, automatically determining and replying to relevant news, creating custom menus, clicking custom menus, and performing corresponding operations, user lists, and so on, I feel that the current development mode is no different from the subscription mode.

Here is a test example of the test response. The Code is as follows:

<? Php/*** wechat php test * // define your tokendefine ("TOKEN", "token on your application"); $ wechatObj = new wechatCallbackapiTest (); $ wechatObj-> valid (); class wechatCallbackapiTest {public function valid () {$ echoStr = $ _ GET ["echostr"]; // valid signature, option if ($ this-> checkSignature () {$ this-> responseMsg (); exit;} public function responseMsg () {// get post data, may be due to the different environments $ PostStr = $ GLOBALS ["HTTP_RAW_POST_DATA"]; // extract post data if (! Response ($ postStr) {$ postObj = simplexml_load_string ($ postStr, 'simplexmlelement', LIBXML_NOCDATA); $ fromUsername = $ postObj-> FromUserName; $ toUsername = $ postObj-> ToUserName; $ keyword = trim ($ postObj-> Content); $ time = time (); $ msgType = "text"; $ textTpl = "<xml> <ToUserName> <! [CDATA [% s]> </ToUserName> <FromUserName> <! [CDATA [% s]> </FromUserName> <CreateTime> % s </CreateTime> <MsgType> <! [CDATA [% s]> </MsgType> <Content> <! [CDATA [% s]> </Content> <FuncFlag> 0 </FuncFlag> </xml> "; if (! Emptyempty ($ keyword) {$ contentStr = $ this-> keyrep ($ keyword); if (emptyempty ($ contentStr) {$ contentStr = "You did it on purpose, no culture is really terrible "; // you mean it, no culture is really terrible;} // $ contentStr = @ iconv ('utf-8', 'gb2312 ', $ keyword); $ resultStr = sprintf ($ textTpl, $ fromUsername, $ toUsername, $ time, $ msgType, $ contentStr); echo $ resultStr ;} else {$ contentStr = 'it's terrible to have no culture. You can't type it! '; // $ This-> keyrep ($ keyword); // $ contentStr = @ iconv ('utf-8', 'gb2312', $ keyword ); $ resultStr = sprintf ($ textTpl, $ fromUsername, $ toUsername, $ time, $ msgType, $ contentStr); echo $ resultStr ;}} else {echo ""; exit ;}} private function checkSignature () {$ signature =$ _ GET ["signature"]; $ timestamp =$ _ GET ["timestamp"]; $ nonce = $ _ GET ["nonce"]; $ token = TOKEN; $ tmpArr = array ($ token, $ timestamp, $ nonce ); Sort ($ tmpArr); $ tmpStr = implode ($ tmpArr); $ tmpStr = sha1 ($ tmpStr); if ($ tmpStr = $ signature) {return true ;} else {return false ;}} function keyrep ($ key) {// return $ key; if ($ key = 'Hi' | $ key = '') {$ mt = mt_rand ); $ array = array (1 => 'suicide.
