基于PHP实现微信小程序客服消息功能 开启客服消息开启消息推送 地址消息加密方式：可以根据自己需要选择，本例选择”兼容模式“。数据格式：json相对于xml来说，从压缩效率及传输效率更具优势，这里我们选json。示例代码<?php /** * @author anderyly * @email admin@aaayun.cc * @link http://blog.aaayun.cc * @copyright Copyright (c) 2022 */ use ay\lib\Curl; class WeChat { public static $token = 'xxx'; // Token(令牌) public static $key = 'xxx'; // EncodingAESKey(消息加密密钥) public static $appid = 'xxx'; public static $secret = 'xxx'; public function index() { // $this->checkSignature(self::$token); // 验证 $data = file_get_contents('php://input'); $this->send($data, self::$appid, self::$secret); } public function checkSignature($token) { $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 == $signature ) { exit($_GET['echostr']); } } public function getAccessToken($appid, $secret) { $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $appid . "&secret=" . $secret; $row = Curl::url($url)->get(); $row = json_decode($row, true); return $row['access_token'] ?? false; } public function send($data, $appid, $secret) { $data = json_decode($data, true); $accessToken = $this->getAccessToken($appid, $secret); $url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" . $accessToken; $r = [ "touser" => $data['FromUserName'] ]; $r['msgtype'] = "link"; $r['link'] = [ "title" => "轻风云", "description" => "云淡风轻，于事安然", "url" => "http://blog.aaayun.cc", "thumb_url" => "http://blog.aaayun.cc/avatar.png" ]; $json = json_encode($r, JSON_UNESCAPED_UNICODE); Curl::url($url)->param($json)->post('json'); } }
