1.在con.fig文件里面配置TOKEN,APPID,APPSECRET值
2.控制器WeixinController代码:
<?php /** * 微信父类控制器 * @author Songle * */ namespace Weixin\Controller; use Think\Controller; class WeixinController extends Controller { private $last_time=null; private $appid=null; private $appsecret=null; function __construct(){ parent::__construct(); $token=C('TOKEN'); $this->appid=C('APPID'); $this->appsecret=C('APPSECRET'); //获取微信服务器GET请求的4个参数 $signature = I('signature'); $timestamp = I('timestamp'); $nonce = I('nonce'); $echostr = I('echostr'); if (! empty ( $echostr) && ! empty ( $signature ) && ! empty ($nonce )) { //定义一个数组,存储其中3个参数,分别是timestamp,nonce和token $tempArr = array($nonce,$timestamp,$token); //进行排序 sort($tempArr,SORT_STRING); //将数组转换成字符串 $tmpStr = implode($tempArr); //进行sha1加密算法 $tmpStr = sha1($tmpStr); //判断请求是否来自微信服务器,对比$tmpStr和$signature if($tmpStr == $signature) { echo $echostr; } exit(); } } /** * 获取tooken值 */ public function getTooken(){ $this->last_time = 1448012924; $access_token = "填写上一次的token值"; //需要替换成自己的 if(time() > ($this->last_time + 7200)) { //GET请求的地址 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$this->appid}&secret={$this->appsecret}"; $access_token_Arr = $this->https_request($url); $this->last_time = time(); return $access_token_Arr['access_token']; } return $access_token; } //https请求(支持GET和POST) public function https_request($url,$data = null) { $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); if(!empty($data)) { curl_setopt($ch,CURLOPT_POST,1); //模拟POST curl_setopt($ch,CURLOPT_POSTFIELDS,$data); //POST内容 } $outopt = curl_exec($ch); curl_close($ch); $outopt = json_decode($outopt,true); return $outopt; } }
