微信开发之二维码生成类

这篇文章主要介绍了PHP微信开发之二维码生成类,本文使用微信接口实现二维码的生成,并直接给出示例代码,需要的朋友可以参考下<?php/** * Created by PhpStorm. * User: bin * Date: 15-1-16 * Time: 上午9:48 */namespace HomeCommon;// 微信处理类set_time_limit(30);class Weixin{//构造方法static $qrcode_url = "https://api.weixin.qq.com/cgi-bin/qrcode/create?";static $token_url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&";static $qrcode_get_url = "https://mp.weixin.qq.com/cgi-bin/showqrcode?";//生成二维码public function getEwm($wechatid,$fqid,$type = 1){$wechat = M('Member_public')->where(array('id'=> $wechatid))->find();$appid = $wechat['appid'];$secret = $wechat['secret'];$ACCESS_TOKEN = $this->getToken($appid,$secret);$url = $this->getQrcodeurl($ACCESS_TOKEN,$fqid,1);return DownLoadQr($url,time());}protected function getQrcodeurl($ACCESS_TOKEN,$fqid,$type = 1){$url = self::$qrcode_url.'access_token='.$ACCESS_TOKEN;if($type == 1){//生成永久二维码$qrcode= '{"action_name": "QR_LIMIT_SCENE", "action_info": {"scene": {"scene_id": '.$fqid.'}}}';}else{//生成临时二维码$qrcode = '{"expire_seconds": 1800, "action_name": "QR_SCENE", "action_info": {"scene": {"scene_id": '.$fqid.'}}}';}$result = $this->http_post_data($url,$qrcode);$oo = json_decode($result[1]);if(!$oo->ticket){$this->ErrorLogger('getQrcodeurl falied.
