PHP实现QQ第三方登录的方法
Posted PHP-小菜

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了PHP实现QQ第三方登录的方法相关的知识,希望对你有一定的参考价值。
前言:
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
.
$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
.
"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
$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。
5.QQ_LoginAction.class.php 文件代码:【用的ThinkPHP3.2】
