PHP实现QQ快速登录，罗列了三种方法
方法一：面向过程，回调地址和首次触发登录写到了一个方法页面【因为有了if做判断】，
方法二，三：面向对象
1.先调用登录方法，向腾讯发送请求，
2.腾讯携带本网站唯一对应参数OPENID,ACCESSTOKEN，返回到对应回调页面，
3.回调页面接受到腾讯的参数后，通过这个两个参数，再发出对应的请求，如查询用户的数据。
4.腾讯做出对应的操作，如返回这个用户的数据给你
即使你没看懂，也没关系，按照我下面的流程来，保证你可以实现。
前期准备：
使用人家腾讯的功能，总得和人家打招呼吧！
QQ互联首页：http://connect.qq.com/
进入网址后，按如下操作来：
一.进入官网
二.申请创建【网站】应用
三.按要求填写资料
注意网站地址：填写你要设置快速登录的网址，eg:http://www.test.com;
回调地址:填写你发送QQ快速登陆后，腾讯得给你信息，这个信息往此页面接受。eg:http://www.test.com/accept_info.php
【详细的申请填写，请见官方提示，这里不做赘述】
四.申请成功后，完善信息
最终要求，获得APP_ID ，APP_KEY
五.代码部分：
在你对应的PHP文件内写入，如下
方法一，面向过程法
使用方法：配置$app_id，$app_secret，$my_url后，其他原封复制即可，$user_data为返回的登录信息
代码：
———————————————————————————————————————————————————-
//应用的APPID
$app_id
=
"你的APPID"
;
//应用的APPKEY
$app_secret
=
"你的APPKEY"
;
//【成功授权】后的回调地址，即此地址在腾讯的信息中有储存
$my_url
=
"你的回调网址"
;
//Step1：获取Authorization Code
session_start();
$code
=
$_REQUEST
[
"code"
];
//存放Authorization Code
if
(
empty
(
$code
))
{
//state参数用于防止CSRF攻击，成功授权后回调时会原样带回
$_SESSION
[
‘state‘
] = md5(uniqid(rand(), TRUE));
//拼接URL
$dialog_url
=
"https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id="
.
$app_id
.
"&redirect_uri="
. urlencode(
$my_url
) .
"&state="
.
$_SESSION
[
‘state‘
];
echo
(
"<script> top.location.href=‘"
.
$dialog_url
.
"‘</script>"
);
}
//Step2：通过Authorization Code获取Access Token
if
(
$_REQUEST
[
‘state‘
] ==
$_SESSION
[
‘state‘
] || 1)
{
//拼接URL
$token_url
=
"https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&"
.
"client_id="
.
$app_id
.
"&redirect_uri="
. urlencode(
$my_url
)
.
"&client_secret="
.
$app_secret
.
"&code="
.
$code
;
$response
=
file_get_contents
(
$token_url
);
if
(
strpos
(
$response
,
"callback"
) !== false)
//如果登录用户临时改变主意取消了，返回true!==false,否则执行step3
{
$lpos
=
strpos
(
$response
,
"("
);
$rpos
=
strrpos
(
$response
,
")"
);
$response
=
substr
(
$response
,
$lpos
+ 1,
$rpos
-
$lpos
-1);
$msg
= json_decode(
$response
);
if
(isset(
$msg
->error))
{
echo
"<h3>error:</h3>"
.
$msg
->error;
echo
"<h3>msg :</h3>"
.
$msg
->error_description;
exit
;
}
}
//Step3：使用Access Token来获取用户的OpenID
$params
=
array
();
parse_str
(
$response
,
$params
);
//把传回来的数据参数变量化
$graph_url
=
"https://graph.qq.com/oauth2.0/me?access_token="
.
$params
[
‘access_token‘
];
$str
=
file_get_contents
(
$graph_url
);
if
(
strpos
(
$str
,
"callback"
) !== false)
{
$lpos
=
strpos
(
$str
,
"("
);
$rpos
=
strrpos
(
$str
,
")"
);
$str
=
substr
(
$str
,
$lpos
+ 1,
$rpos
-
$lpos
-1);
}
$user
= json_decode(
$str
);
//存放返回的数据 client_id ，openid
if
(isset(
$user
->error))
{
echo
"<h3>error:</h3>"
.
$user
->error;
echo
"<h3>msg :</h3>"
.
$user
->error_description;
exit
;
}
//echo("Hello " . $user->openid);
//echo("Hello " . $params[‘access_token‘]);
//Step4：使用<span >openid,</span><span >access_token来获取所接受的用户信息。</span>
$user_data_url
=
"https://graph.qq.com/user/get_user_info?access_token={$params[‘access_token‘]}&oauth_consumer_key={$app_id}&openid={$user->openid}&format=json"
;
$user_data
=
file_get_contents
(
$user_data_url
);
//此为获取到的user信息
}
else
{
echo
(
"The state does not match. You may be a victim of CSRF."
);
}
———————————————————————————————————————————————————-
方法二，面向对象 使用类QQ_LoginAction.class
使用方法：
1.在QQ_LoginAction.class中正确配置 APPID，APPKEY CALLBACK(回调网址)
2.在调用方法中，代码：
$qq_login = new \Component\QQ_LoginAction(); //引入此类文件即可
$qq_login
->qq_login();
3.在回调页面中，代码：
$qc = new \Component\QQ_LoginAction();
$acs
=
$qc
->qq_callback();<span style=
"white-space:pre"
>
//access_token
$oid
=
$qc
->get_openid();<span style=
"white-space:pre"
>
//openid
$user_data
=
$qc
->get_user_info();<span style=
"white-space:pre"
>
//get_user_info()为获得该用户的信息，其他操作方法见API文档
4.$user_data即为返回的用户数据。

方法三，面向对象 使用腾讯给的SDK
使用方法:腾讯SDK，API写的很详细，不做赘述
地址：http://wiki.connect.qq.com/%E7%BD%91%E7%AB%99%E6%8E%A5%E5%85%A5%E6%A6%82%E8%BF%B0
这样就实现了QQ快捷登录，其实很简单的，大家可以试一试。
还有什么不清楚的，可以看看官方介绍，更详细，
Tips:如何在本地测试QQ快速登录
方法：修改HOST配置文件
1. 打开C:\Windows\System32\drivers\etc\host
2. 添加127.0.0.1 www.test.com
然后操作就可以了。
