php第三方登陆SDK程序代码（许昌鲤鱼it编程培训
1、Qq_sdk.php
代码如下复制代码
<?php
/**
* QQ开发平台 SDK
* 作者：偶尔陶醉
* blog: www.stutostu.com
*/
class Qq_sdk{
//配置APP参数
private $app_id = 你的APP ID;
private $app_secret = ‘你的APP_secret’;
private $redirect = 你的回调地址;
function __construct()
{
}
/**
* [get_access_token 获取access_token]
* @param [string] $code [登陆后返回的$_GET['code']]
* @return [array] [expires_in 为有效时间 , access_token 为授权码 ; 失败返回 error , error_description ]
*/
function get_access_token($code)
{
//获取access_token
$token_url = ‘https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&’
. ‘client_id=’ . $this->app_id . ‘&redirect_uri=’ . urlencode($this->redirect)//回调地址
. ‘&client_secret=’ . $this->app_secret . ‘&code=’ . $code;
$token = array();
//expires_in 为access_token 有效时间增量
parse_str($this->_curl_get_content($token_url), $token);
return $token;
}
/**
* [get_open_id 获取用户唯一ID，openid]
* @param [string] $token [授权码]
* @return [array] [成功返回client_id 和 openid ;失败返回error 和 error_msg]
*/
function get_open_id($token)
{
$str = $this->_curl_get_content(‘https://graph.qq.com/oauth2.0/me?access_token=’ . $token);
if (strpos($str, “callback”) !== false)
{
$lpos = strpos($str, “(“);
$rpos = strrpos($str, “)”);
$str = substr($str, $lpos + 1, $rpos – $lpos -1);
}
$user = json_decode($str, TRUE);
return $user;
}
/**
* [get_user_info 获取用户信息]
* @param [string] $token [授权码]
* @param [string] $open_id [用户唯一ID]
* @return [array] [ret：返回码，为0时成功。msg为错误信息,正确返回时为空。...params]
*/
function get_user_info($token, $open_id)
{
//组装URL
$user_info_url = ‘https://graph.qq.com/user/get_user_info?’
. ‘access_token=’ . $token
. ‘&oauth_consumer_key=’ . $this->app_id
. ‘&openid=’ . $open_id
. ‘&format=json’;
$info = json_decode($this->_curl_get_content($user_info_url), TRUE);
return $info;
}
private function _curl_get_content($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, $url);
//设置超时时间为3s
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 3);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
}
/* end of Qq_sdk.php */
2、使用方法：在你网站上放置超链接，地址为：https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=你的APP_ID&redirect_uri=你的回调地址
在回调地址上调用我上面这个qq_sdk即可
3、demo如下：
代码如下复制代码
if(empty($_GET['code']))
{
exit(‘参数非法’);
}
include(‘qq_sdk’);
$qq_sdk = new Qq_sdk();
$token = $qq_sdk->get_access_token($_GET['code']);
print_r($token);
$open_id = $qq_sdk->get_open_id($token['access_token']);
print_r($open_id);
$user_info = $qq_sdk->get_user_info($token['access_token'], $open_id['openid']);
print_r($user_info);
