PHP开发者必备：QQ接口对接实战指南

<?php

$appid = '你的App ID';
$appkey = '你的App Key';
$callback = 'http://your-website.com/callback.php';

// 第一步，获取Authorization Code
$auth_url = "https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id={$appid}&redirect_uri={$callback}&state=your_state";

// TODO: 将用户重定向到$auth_url进行QQ登录

// 第二步，通过Authorization Code获取Access Token
$code = $_GET['code'];
$get_token_url = "https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id={$appid}&client_secret={$appkey}&code={$code}&redirect_uri={$callback}";
$response = file_get_contents($get_token_url);
parse_str($response, $result);
$access_token = $result['access_token'];
$expires_in = $result['expires_in'];
$refresh_token = $result['refresh_token'];

// 第三步，使用Access Token获取用户OpenID
$get_openid_url = "https://graph.qq.com/oauth2.0/me?access_token={$access_token}";
$response = file_get_contents($get_openid_url);
if (strpos($response, "callback") !== false) {
    $lpos = strpos($response, "(");
    $rpos = strrpos($response, ")");
    $json_str = substr($response, $lpos + 1, $rpos - $lpos - 1);
    $result = json_decode($json_str, true);
    $openid = $result['openid'];
}

// 第四步，使用Access Token和OpenID获取用户资料
$get_user_info_url = "https://graph.qq.com/user/get_user_info?access_token={$access_token}&oauth_consumer_key={$appid}&openid={$openid}";
$user_info = json_decode(file_get_contents($get_user_info_url), true);

// TODO: 处理用户登录或注册逻辑，将用户信息存储到数据库或Session中
