这篇文章主要为大家分享了PHP实现微信网页授权开发教程,开发者可以通过授权后获取用户的基本信息,感兴趣的小伙伴们可以参考一下

微信网页授权是服务号才有的高级功能,开发者可以通过授权后获取用户的基本信息;在此之前,想要获取消息信息只能在用户和公众号交互时根据openid获取用户信息;而微信网页授权可在不需要消息交互,也不需要关注的情况下获取用户的基本信息。

微信网页授权时通过OAuth2.0完成的,整个过程分为三步:

  • 用户授权,获取code;

  • 根据code获取access_token【可通过refresh_token刷新获取较长有效期】

  • 通过access_token和openid获取用户信息

对微信网页授权过程做了简单封装:

<?php    /**  * 微信授权相关接口  */   class Wechat {       //高级功能-》开发者模式-》获取   private $app_id = &#39;xxx&#39;;   private $app_secret = &#39;xxxxxxx&#39;;         /**    * 获取微信授权链接    *     * @param string $redirect_uri 跳转地址    * @param mixed $state 参数    */  public function get_authorize_url($redirect_uri = &#39;&#39;, $state = &#39;&#39;)   {     $redirect_uri = urlencode($redirect_uri);     return "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$this->app_id}&redirect_uri={$redirect_uri}&response_type=code&scope=snsapi_userinfo&state={$state}#wechat_redirect";   }       /**    * 获取授权token    *     * @param string $code 通过get_authorize_url获取到的code    */  public function get_access_token($app_id = &#39;&#39;, $app_secret = &#39;&#39;, $code = &#39;&#39;)   {     $token_url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$this->app_id}&secret={$this->app_secret}&code={$code}&grant_type=authorization_code";     $token_data = $this->http($token_url);           if($token_data[0] == 200)     {       return json_decode($token_data[1], TRUE);     }           return FALSE;   }       /**    * 获取授权后的微信用户信息    *     * @param string $access_token    * @param string $open_id    */  public function get_user_info($access_token = &#39;&#39;, $open_id = &#39;&#39;)   {     if($access_token && $open_id)     {       $info_url = "https://api.weixin.qq.com/sns/userinfo?access_token={$access_token}&openid={$open_id}&lang=zh_CN";       $info_data = $this->http($info_url);               if($info_data[0] == 200)       {         return json_decode($info_data[1], TRUE);       }     }           return FALSE;   }       public function http($url, $method, $postfields = null, $headers = array(), $debug = false)   {     $ci = curl_init();     /* Curl settings */    curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);     curl_setopt($ci, CURLOPT_CONNECTTIMEOUT, 30);     curl_setopt($ci, CURLOPT_TIMEOUT, 30);     curl_setopt($ci, CURLOPT_RETURNTRANSFER, true);        switch ($method) {       case &#39;POST&#39;:         curl_setopt($ci, CURLOPT_POST, true);         if (!empty($postfields)) {           curl_setopt($ci, CURLOPT_POSTFIELDS, $postfields);           $this->postdata = $postfields;         }         break;     }     curl_setopt($ci, CURLOPT_URL, $url);     curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);     curl_setopt($ci, CURLINFO_HEADER_OUT, true);        $response = curl_exec($ci);     $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE);        if ($debug) {       echo "=====post data======\r\n";       var_dump($postfields);          echo &#39;=====info=====&#39; . "\r\n";       print_r(curl_getinfo($ci));          echo &#39;=====$response=====&#39; . "\r\n";       print_r($response);     }     curl_close($ci);     return array($http_code, $response);   }    }
