PHP實作QQ快速登入的方法

前言：
PHP實現QQ快速登錄，羅列了三種方法
方法一：面向過程，回調地址和首次觸發登錄寫到了一個方法頁面【因為有了if做判斷】，
方法二，三：物件導向
1.先呼叫登入方法，向騰訊發送請求，
2.騰訊攜帶本網站唯一對應參數OPENID,ACCESSTOKEN，返回對應回呼頁面，
3.回呼頁面接受到騰訊的參數後，透過這個兩個參數，再發出對應的請求，例如查詢使用者的資料。
4.騰訊做出對應的操作，如返回這個用戶的數據給你
即使你沒看懂，也沒關係，按照我下面的流程來，保證你可以實現。
前期準備：
使用人家騰訊的功能，總得跟人家打招呼吧！
QQ互聯首頁：http://connect.qq.com/
進入網址後，如下：
一.進入官網
二.申請建立官網【
三.依要求填寫資料
注意網站地址：填寫你要設定快速登入的網址，eg:http://www.test.com;
回呼地址:填寫你發送QQ快速登陸後，騰訊得給你信息，這個信息往此頁面接受。 eg:http://www.test.com/accept_info.php
【詳細的申請填寫，請見官方提示，這裡不做贅述】
四.申請成功後，完善信息
最終要求，獲得APP_ID ，APP_KEY五.代碼部分：
在你對應的PHP文件內寫入，如下
方法一，面向過程法
使用方法：配置$app_id，$app_secret，$my_url後，其他原封複製即可，$user_data為傳回的登入資訊
//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 style="font-family: Arial, Helvetica, sans-serif;">openid,</span><span style="font-family: Arial, Helvetica, 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，物件導向使用類別QQ_LoginAction.class
使用方法：
1.在QQ_LoginAction.class中正確配置APPID，APPKEY CALLBACK(回呼網址)2.在呼叫方法中，代碼：
$qq_login = new \Component\QQ_LoginAction(); //引入此类文件即可 $qq_login->qq_login(); //调用登录方法，向腾讯发出快速登录请求3.在回呼頁面中，代碼：
$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即為傳回的使用者資料。 5.QQ_LoginAction.class.php 檔案代碼：【用的ThinkPHP3.2】
<?php
namespace Component;
session_start();
define('APPID','XXXX'); //appid
define('APPKEY','XXXX'); //appkey
define('CALLBACK','XXXX'); //回调地址

}方法三，物件導向使用騰訊給的SDK
使用方法:騰訊SDK，API寫的很詳細，不做贅述地址： http://wiki.connect.qq.com/%E7%BD%91%E7%AB%99%E6%8E%A5%E5%85%A5%E6%A6%82%E8%BF%B0
這樣就實現了QQ快速登錄，其實很簡單的，大家可以試試看。
Tips:如何在本地測試QQ快速登入
方法：修改HOST設定檔
1. 開啟C:WindowsSystem32driversetchost
2. 新增127.0.0.1 www .test.com
