Introduction to PHP WeChat development text automatic reply

This article mainly gives you a detailed introduction to PHP development-related materials for simple implementation of automatic text reply, interested friends can refer to this article's PHP Development text to automatically reply to the relevant information, interested friends can refer

First, register an account on the public platform (many items are required for registration). After registration, log in. You can see the "Developer Center" on the left. Before you start the developer center, it seems that you need to complete some information and follow the steps to complete it. Go to the developer center and edit

Header ('content-type: text/html; charset = utf-8 '); define ("TOKEN", "my_weixin "); // define your token $ wx = new wechatCallbackapiTest (); if ($ _ GET ['echostr']) {$ wx-> valid (); // If echostr is sent, perform verification} else {$ wx-> responseMsg (); // if no echostr exists, return the message} class wechatCallbackapiTest {public function valid () {// valid signature, option $ echoStr = $ _ GET ["echostr"]; if ($ this-> checkSignature () {// call the verification field echo $ echoStr; exit; } Public function responseMsg () {// get post data, May be due to the different environments $ postStr = $ GLOBALS ["HTTP_RAW_POST_DATA"]; // receive XML data // extract post data if (! Empty ($ postStr) {// Parse the XML from post as an object $ postObj = simplexml_load_string ($ postStr, 'simplexmlelement', LIBXML_NOCDATA ); $ fromUsername = $ postObj-> FromUserName; // The user requesting the message $ toUsername = $ postObj-> ToUserName; // "my" public id $ keyword = trim ($ postObj-> Content); // message Content $ time = time (); // timestamp $ msgtype = 'text'; // Message Type: text $ textTpl ="

 "; If ($ keyword = 'hehes') {$ contentStr = 'Hello world !!! '; $ ResultStr = sprintf ($ textTpl, $ fromUsername, $ toUsername, $ time, $ msgtype, $ contentStr); echo $ resultStr; exit ();} else {$ contentStr = 'input hehe test'; $ resultStr = sprintf ($ textTpl, $ fromUsername, $ toUsername, $ time, $ msgtype, $ contentStr); echo $ resultStr; exit () ;}} else {echo ""; exit ;}// verification field 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 ;}}}

If a message is sent, the system prompts that the public platform cannot provide a shared service temporarily. please try again later. Most of them are code syntax problems. check the syntax errors and try again.

Appendix:

When a new user pays attention to your public account, information is automatically returned: (add this code before determining $ keyword ).

If ($ postObj-> MsgType = 'event') {// if the message type in XML is event if ($ postObj-> event = 'subscribe ') {// if it is a subscription event $ contentStr = "Welcome to subscribe to misaka last summer! \ N more highlights: http://www.php.cn/"; $ resultStr = sprintf ($ textTpl, $ fromUsername, $ toUsername, $ time, $ msgtype, $ contentStr); echo $ resultStr; exit ();}}
