准备阶段
- 国内服务器和备案域名
- 需要你有张独一无二本人的身份证
- 你正面手持身份证的图片
- 一张100px*100px的网站图标
申请QQ登录的权限
首先访问qq互联,点击我直接访问
登陆完成后我们点击面的应用管理
然后我们点击头像进入页面后填写相关的信息等待审核就好了(审核时间大概在一天左右吧)
创建应用
回到管理页面点击创建应用>创建网站应用
然后填写你的网站的相关信息
网站地址填你要用QQ登录的网址,回调地址填到你要登录的页面的目录下,再加/qqlogin.php 例如我要用www.xfabe.com进行QQ登录,登录页面在路径www.xfabe.com/user/login.php 那这个回调地址就填www.xfabe.com/user/qqlogin.php 提供方可以随意,然后再把备案号填完就行,最后上传下图标即可,然后等待审核(一天左右吧)
最后然后记录你的APP ID和APP Key,在你的登录页面加上QQ登录的按钮然后指向回调域
最后上传qqlogin.php代码
php
<?php
include '../includes/config.php';//这里你加载你网站程序的运行文件
//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 = "你填写的回调地址";
//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="

//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)
