<?php

$appId = 'yourAppId';
$secret = 'yourSecret';
// 获取access_token
$accessTokenUrl = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appId}&secret={$secret}";
$accessTokenResponse = file_get_contents($accessTokenUrl);
$accessTokenData = json_decode($accessTokenResponse, true);
$accessToken = $accessTokenData['access_token'];
// 处理签到请求
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$data = json_decode(file_get_contents('php://input'), true);
$openid = $data['openid'];
// 记录签到信息(示例:存入数据库)
$db = new PDO('mysql:host=localhost;dbname=yourDB', 'username', 'password');
$stmt = $db->prepare("INSERT INTO signin_records (openid, signin_time) VALUES (?, NOW())");
$stmt->execute([$openid]);
echo json_encode(['message' => '签到成功']);
} else {
echo json_encode(['message' => '请求方法错误']);
}
?>
通过以上步骤和代码示例,可以实现一个基本的微信公众号签到功能。根据具体需求,可以进一步优化和扩展功能。
