A _php example of the authorization library for micro-credit Web pages based on CI framework

This paper illustrates the authorization Library of Micro-trust Web pages based on CI framework. Share to everyone for your reference, specific as follows:

This demonstrates the authorization function of the micro-credit page based on the CI framework.

1. Micro-trust Class library, Web page authorization placed in the Libraries folder

<?php if (! defined (' BasePath ')) exit (' No Direct script access allowed ');
    Class Weixin {private $appId;
    Private $appSecret;
      function __construct () {$this->appid = Trim (' your appId ');

      State=state#wechat_redirect ";
    return $url; /* * to Exchange code for access_token*/function Access_token ($code) {/* acquired to Access_token and openid*/$post _url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid= $this->appid&secret= $this->appsecret
             &code= $code &grant_type=authorization_code ";
      echo $post _url;exit ();
      $return = $this->postdata ($post _url);
      Print_r ($return); exit ();
   $access _token = $return [' Access_token '];   $openid = $return [' OpenID ']; /* Access to micro-credit user Data * * * $get _userinfo = "https://api.weixin.qq.com/sns/userinfo?access_token= $access _token&openid=$
      OPENID&AMP;LANG=ZH_CN ";

    return $userinfo; function eff ($access _token, $openid) {/* detect access_token correctly, errcode=0 as correct/$eff _url = "HTTPS://API.W
      eixin.qq.com/sns/auth?access_token= $access _token&openid= $openid ";
      $get _eff =json_decode (file_get_contents ($eff _url));
    return $get _eff; ///Curl to submit code in exchange for Access_token data function PostData ($url) {header (' Content-type:text/html;charset=utf
       -8 ');
      echo $url; exit ();
      $curl = Curl_init ();
      curl_setopt ($curl, Curlopt_url, $url);

      Curl_close ($curl);
      Var_dump ($output); exit ();

      $access = Json_decode ($output, true);
    return $access; /* This position starts with the controller index () incoming micro-user data processing * * Function save_session ($data) {foreach ($data as $k

 }
}
