PHP Oauth授权和本地加密实现方法

1.oauth（开放授权）是一个开放标准，允许用户让第三方应用访问该用户在某一网站上存储的私密资源（如照片，视频，联系人列表），而无需将用户名和密码提供给第三方

关键字：appkey appsecret token(令牌)

2.sso授权

如果本地手机装有微博客户端，则直接跳转到微博客户端，只需点击授权按钮，就可以登陆了 

qq第三方登陆使用oauth2.0实现，测试代码

点击下面的连接

https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=101334262&redirect_uri=http://www.qingguow.cn/sso.php

具体代码sso.php文件：

<?php
// qq登陆类
class sso{
  const app_id="101334262";
  const app_key="xxxxxxxxxxxxxxx";
  //初始化
  public static function init(){
    header("content-type:text/html;charset=utf-8");
  }
    //主函数
  public static function main(){
    //请求控制
    $action=$_get['action'];
    if(!empty($action)){
      sso::$action();
      return;
    }
    
    $par = 'grant_type=authorization_code'
    . '&client_id='.sso::app_id
    . '&client_secret='.sso::app_key
    . '&code='.$_request['code']
    . '&redirect_uri='.urlencode('http://www.qingguow.cn/sso.php');
    $rec=sso::posturlcontents("https://graph.qq.com/oauth2.0/token",$par);
    if(strpos($rec, 'access_token') !== false) {
      parse_str($rec, $accesstoken);
      $openidjson=sso::geturlcontents("https://graph.qq.com/oauth2.0/me?callback=callback&access_token={$accesstoken['access_token']}");
      $openidjson=str_replace("callback( ", "", $openidjson);
      $openidjson=str_replace(");", "", $openidjson);
      $openidjson=json_decode($openidjson,true);
      header("location:sso.php?action=getqqinfo&openid={$openidjson['openid']}&access_token={$accesstoken['access_token']}");
    }
  }
  //获取用户信息
  public static function getqqinfo(){
    sso::init();
    $openid=$_get['openid'];
    $access_token=$_get['access_token'];
    $userjson=sso::geturlcontents("https://graph.qq.com/user/get_user_info?openid={$openid}&access_token={$access_token}&oauth_consumer_key=".sso::app_id);
    $user=json_decode($userjson,true);
    print_r($user);
  }
  //get方式请求数据
  public static function geturlcontents($url){
    $ch = curl_init();
    curl_setopt($ch, curlopt_ssl_verifypeer, false);
    curl_setopt($ch, curlopt_header, false);
    curl_setopt($ch, curlopt_followlocation, true);
    curl_setopt($ch, curlopt_url, $url);
    curl_setopt($ch, curlopt_referer, $url);
    curl_setopt($ch, curlopt_returntransfer, true);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
  }
  //post请求数据
  public static function posturlcontents($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;
  }

}
sso::main();
