}放出输出的demo，有用的上的可以参考//微信认证链接<br>
public function wxurl(){<br>
import('MyClass.Wechatauth',APP_PATH);<br>
$Wechat = new wechatauth();<br>
$token = session('token'); //查看是否已经授权<br>
if (!empty($token)) {<br>
print_r($token);<br>
$state = $Wechat->check_access_token($token['access_token'],$token['openid']); //检验token是否可用(成功的信息："errcode":0,"errmsg":"ok")<br>
print_r($state);<br>
}<br>
$url = $Wechat->get_authorize_url('http://twx.vjiankang.org/wsite/test/wxrurl','1'); //此处链接授权后，会跳转到下方处理<br>
echo '<a>授权</a>';<br>
<br>
}<br>
<br>
//微信返回字符串<br>
public function wxrurl(){<br>
import('MyClass.Wechatauth',APP_PATH);<br>
$Wechat = new wechatauth();<br>
print_r($_GET); //授权成功后跳转到此页面获取的信息<br>
<br>
$token = $Wechat->get_access_token('','',$_GET['code']); //确认授权后会，根据返回的code获取token<br>
print_r($token);<br>
session('token',$token); //保存授权信息<br>
<br>
$user_info = $Wechat->get_user_info($token['access_token'],$token['openid']); //获取用户信息<br>
print_r($user_info);<br>
<br>
}需要注意的是，我们用于返回的url，需要在微信公众平台-》开发者-》auth认证里修改为同一域名下
