谈谈自己对于Auth2.0的见解

  Auth的原理网上有很多,我这里就不在赘述了。

  这里有张时序图我个人觉得是比较合理而且直观的,(感谢这篇博文:http://justcoding.iteye.com/blog/1950270)

谈谈自己对于Auth2.0的见解

  参照这个流程,模拟了下部分代码,当然是尽可能的以简单的形式去表达下自己的见解

  模拟了配置文件去掉数据库处理的部分

config.php 定义了公司及对应的操作用户的权限

<?php
return array(
'app'=>array(
'a1'=>array(
'accesskey'=>'123456',//凭证
'type'=>0,//聚合这里规定type对应的请求权限
'appname'=>'gavinjun',
),
),
'type'=>array(
array(
'获取用户的信息','获取用户的金钱',
),
),
);

user_config.php 用户表的模拟

<?php
return array(
'admin'=>'123456',
);
<?php 

//权限2.0的主程
class Auto{
private $vession=2.0;
private $notic=null;
public function __construct(){
$notic = require 'config.php';
$this->notic = $notic;
}
//校验商户
public function check($_param=array()){
if(empty($_param)){
return false;
}
//获取传过来的accesskey appid
$appid = !empty($_param['appid'])?$_param['appid']:0;
$accesskey=!empty($_param['accesskey'])?$_param['accesskey']:'';
if(!$appid||!$accesskey)
return false;
//校验开始
$notic = $this->notic;
return $notic['app'][$appid]?$notic['app'][$appid]['accesskey']==$accesskey:false;
}
//用户发起登录请求
public function getLoginCallBack($_param){
if($this->check($_param)){
//校验通过返回临时的token 以下都是不安全的方式只是模拟auto的流程
//这里可以用加密 请求时间|请求完成后跳转地址|用户的md5(accesskey)
return time().'|'.$_param['redirect'].'|'.md5($_param['accesskey']).'|'.$_param['appid'];
}else{
echo '商户未注册';
return false;
}
} //用户输入完用户名和密码之后
public function inLogin($name,$pwd){
$user = require("user_config.php");
return $user[$name]?$user[$name]==$pwd:false;
}
//用户登录完成后带着token值来请求我们的令牌
public function getAceess($_param){
$token = $_param['access_token'];
if(!$token)
return false;
list($time,$redirect,$authkey,$appid) = explode('|',$token);
//请求$appid 获取他的accesskey
$notic = $this->notic;
$accesskey = $notic['app'][$appid]['accesskey'];
if(time()>$time+5*60){
//超过5分钟才请求默认失败
return false;
}
if(md5($accesskey)!=$authkey){
//链接不安全
return false;
}
//返回正式的key
//这个key可以保存在数据库中设置这个key的失效时间 //我这里随便固定了他的accesskey
//给跳转的页面发送一个key 用post的应该,不过模拟就算了
$access = 'success';
return $redirect.'?access='.$access;
} public function doSomeByaccess($access){
//和数据库中做比对 这里不写了,就全部默认成功
if($access){
$appid = 'a1';
}
$notic = $this->notic;
$type = $notic['app'][$appid]['type'];
foreach($notic['type'][$type] as $v){
echo '用户权限:'.$v.'<br>';
} }
}

这里是模拟下这段程序的流程

<?php
//模拟流程
require 'auth2.php';
$auth2= new Auto(); //step 1: 用户点击平台上的登录按钮
//该商户的信息 appid=a1,accesskey=123456
$step1=$auth2->getLoginCallBack(array('appid'=>'a1','accesskey'=>'123456','redirect'=>'http://www.baidu.com'));
//系统内部跳转到登录界面拿到临时token 让用户去登录授权
$access_token = $step1;
/**系统内部的处理流程***/
//系统跳到登录地址?access_token=$step1 用户输入用户名和密码
//模拟用户授权
if($auth2->inLogin('admin','123456')){
//用户同意登录返回了一个令牌$access_token是用户登录请求的时候带上的
$arr['access_token']=$access_token;
$url = $auth2->getAceess($arr);
//这个url会发送给平台,平台拿到这个 令牌可以去访问用户信息
echo $url;
}
/****系统内部处理结束跳转到用户平台地址,发送post信息****/
//假设平台接到这个信息他保存下来了这个accesskey,去读取一遍用户的信息
$url = parse_url($url);
list($access,$accesskey)=explode('=',$url['query']);
$auth2->doSomeByaccess($accesskey);

结果:
