使用thinkphp3.2.3开发微信授权登录详细教程
5163
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
