1. Set the server Domain Name

For example: https://hosts.com

2. Set message push

2.1 Add the server interface test. php to your server. The content of the test. php interface is mainly used to verify whether the message is sent through the token. The code is shown in the official example:

Define ("TOKEN", "xxxxx");/the token $ wechatObj = new wechatAPI (); $ wechatObj-> isValid (); class wechatAPI {public function isValid () // verify the interface. if yes, the echostr parameter {$ echoStr = $ _ GET ["echostr"] is returned. if ($ this-> checkSignature ()) {echo $ echoStr; exit ;}} private function checkSignature () // official verification function {$ 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 ;}}};

2.2 set the background message push information of the Applet

URL (server address): https://hosts.com/xx/test.php

Token: Any conforming string, as defined above "xxxxx"

EncodingAESKey (message encryption key): (it is generated randomly and saved on your own. This encryption key is used for decryption)

Message encryption method: Select plaintext for the time being. You do not need to consider encryption and decryption.
