使用thinkphp3.2.3开发微信授权登录详细教程

最近开发微信,涉及到微信用户登录的问题,研究了一下还是搞定了,整理了一下跟大家贴出来我写的这个代码吧,需要用的东西我都已经定义成常量,需要的话直接修改,以下是代码:
<?php namespace Apps\Controller; use Common\Controller\AppBaseController; define("TOKEN", "");//你微信定义的token define("APPID", "");//你微信定义的appid define("APPSECRET","");//你微信公众号的appsecret class TestController extends AppBaseController //继承的这个控制器没用 你可以继承其他的任意一个 { //第一步:用户同意授权,获取code function accept(){ //这个链接是获取code的链接 链接会带上code参数 $REDIRECT_URI = "http://www.yourdomain.com/wxt_webhome/index.php/Apps/Test/getCode"; echo $REDIRECT_URI."<br>"; $REDIRECT_URI = urlencode($REDIRECT_URI); echo $REDIRECT_URI."<br>"; $scope = "snsapi_userinfo"; echo $scope."<br>"; $state = md5(mktime()); echo $state."<br>"; $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=".APPID."&redirect_uri=".$REDIRECT_URI."&response_type=code&scope=".$scope."&state=".$state."#wechat_redirect"; header("location:$url"); } //用户同意之后就获取code 通过获取code可以获取一切东西了 机智如我 function getCode(){ //获取accse_token $code = I("code"); //echo $code; //echo "<br>"; //用code获取access_yoken $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".APPID."&secret=".APPSECRET."&code=".$code."&grant_type=authorization_code"; //这里可以获取全部的东西 access_token openid scope $res = $this->https_request($url); $res = json_decode($res,true); $openid = $res["openid"]; echo "<pre>"; //print_r($res); //echo $openid; //echo "<br>"; $access_token = $res["access_token"]; //echo $access_token; //这里是获取用户信息 $url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$access_token."&openid=".$openid."&lang=zh_CN"; $res = $this->https_request($url); $res = json_decode($res,true); //写入session print_r($res); //把用户的信息写入session 以备查用 $weixn = $res["openid"]; $nickname = $res["nickname"]; session('weixin',$weixin); header("location:http://www.yourdomain.com/wxt_webhome/test.php"); } function https_request($url, $data = null) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; } }//classend
