增加ThinkSDK的支付宝第三方登录
1、配置文件增加相应参数//支付宝登录<br>
'THINK_SDK_ALIPAY' => array(<br>
'APP_KEY' => '', //应用注册成功后分配的 APP ID<br>
'APP_SECRET' => '', //应用注册成功后分配的KEY<br>
'CALLBACK' => URL_CALLBACK . 'alipay',<br>
),2、相关SDK代码，因为我们公司用的zend framework，我将thinkSDK移植进来肯定做了修改，所以仅供参考。支付宝登录与其他的不同，登录时有sign验证，而且只用请求一次，所以重载了thinkouath的部分类。<?php <br />

}3、获取信息的接口，支付宝默认仅提供userid和usertype，更多需要去申请。另外返回是xml，需要解析，这里就简单做下示例。public static function alipay($token){<br>
$alipay=DKOauth::getInstance('alipay', $token);<br>
$param=array(<br>
'_input_charset'=>'utf-8',<br>
'input_charset'=>'utf-8',<br>
'service'=>'mobile.common.login.userInfo.query',<br>
'token'=>$token['access_token'],<br>
'format'=>'json',<br>
);<br>
$data=$alipay->call('',$param);<br>
return $data;<br>
