  1、首先到微信开放平台申请https://open.weixin.qq.com/ 获取到appid和APPSECRET,前台显示页面如下

  2、PHP处理代码页面

  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.'}');

  }
