大佬教程收集整理的这篇文章主要介绍了PHP实现QQ快速登录的方法,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
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。
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:
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
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:
//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="
. $_SESSION['state'];
echo("");
}
//Step2:通过Authorization Code获取Access Token
if($_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 "
//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,$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 style="font-family: Arial,Helvetica,sans-serif;">openid,</span><span style="font-family: Arial,sans-serif;">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:
3.在回调页面中,代码:
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】
session_start();
define('APPID','XXXX'); //appid
define('APPKEY','XXXX'); //appkey
define('CALLBACK','XXXX'); //回调地址
define('SCOPE','get_user_info,list_album,add_album,upload_pic,add_topic,add_weibo'); //授权接口列表
class QQ_LoginAction {
const GET_AUTH_CODE_URL = "https://graph.qq.com/oauth2.0/authorize";
