首先到微信开放平台申请https://open.weixin.qq.com/ 获取到appid和APPSECRET
PHP处理代码页面
define('APPID', "wx19ba77624e083e08"); define('APPSECRET', "c1a56a5c4247dd44c320c9719c5ceb90"); class class_weixin { var $appid = APPID; var $appsecret = APPSECRET; //构造函数,获取Access Token public function __construct($appid = NULL, $appsecret = NULL) { if($appid && $appsecret){ $this->appid = $appid; $this->appsecret = $appsecret; } //扫码登录不需要该Access Token, 语义理解需要 //1. 本地写入 $res = file_get_contents('access_token.json'); $result = json_decode($res, true); $this->expires_time = $result["expires_time"]; $this->access_token = $result["access_token"]; if (time() > ($this->expires_time + 3600)){ $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->appsecret; $res = $this->http_request($url); $result = json_decode($res, true); $this->access_token = $result["access_token"]; $this->expires_time = time(); file_put_contents('access_token.json', '{"access_token": "'.$this->access_token.'", "expires_time": '.$this->expires_time.'}'); } }
本文介绍如何通过PHP语言实现微信公众号API的接入流程,包括获取Access Token的过程,并提供了具体的代码实现。
