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:面向對象
1.先調用登錄方法,向騰訊發送請求,
2.騰訊攜帶本網站唯一對應參數OPENID,ACCESSTOKEN,返回到對應回調頁面,
3.回調頁面接受到騰訊的參數後,通過這個兩個參數,再發出對應的請求,如查詢用戶的數據。
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,也沒關系,按照我下面的流程來,保證你可以實現。
前期准備:
使用人家騰訊的功能,總得和人家打招呼吧!
QQ互聯首頁:http://connect.qq.com/
進入網址後,按如下操作來:
一.進入官網
二.申請創建【網站】應用
三.按要求填寫資料
注意網站地址:填寫你要設置快速登錄的網址,eg:http://www.test.com;
回調地址: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,$my_url後,其他原封復制即可,$user_data為返回的登錄信息
代碼:
//應用的APPID $app_id = "你的APPID"; //應用的APPKEY $app_secret = "你的APPKEY"; //【成功授權】後的回調地址,即此地址在騰訊的信息中有儲存 $my_url = "你的回調網址"; //Step1:獲取Authorization Code session_start(); $code = $_REQUEST["code"];//存放Authorization Code if(empty($code)) { //state參數用於防止CSRF攻擊,成功授權後回調時會原樣帶回 $_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='" . $dialog_url . "'</script>"); } //Step2:通過Authorization Code獲取Access Token if($_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)//如果登錄用戶臨時改變主意取消了,返回true!==false,否則執行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來獲取用戶的OpenID $params = array(); parse_str($response, $params);//把傳回來的數據參數變量化 $graph_url = "https://graph.qq.com/oauth2.0/me?access_token=".$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);//存放返回的數據 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來獲取所接受的用戶信息。</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);//此為獲取到的user信息 } else { echo("The state does not match. You may be a victim of CSRF."); }
方法二,面向對象 使用類QQ_LoginAction.class
使用方法:
1.在QQ_LoginAction.class中正確配置 APPID,APPKEY CALLBACK(回調網址)
2.在調用方法中,代碼:
$qq_login = new \Component\QQ_LoginAction(); //引入此類文件即可 $qq_login->qq_login(); //調用登錄方法,向騰訊發出快速登錄請求
3.在回調頁面中,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 = $qc->get_user_info();<span style="white-space:pre"> //get_user_info()為獲得該用戶的信息,其他操作方法見API文檔
4.$user_data即為返回的用戶數據。
5.QQ_LoginAction.class.php 文件代碼:【用的ThinkPHP3.2】
<?php namespace Component; session_start(); define('APPID','XXXX'); //appid define('APPKEY','XXXX'); //appkey define('CALLBACK','XXXX'); //回調地址 define('SCOPE','get_user_info,list_album,add_album,upload_pic,add_topic,add_weibo');

方法三,面向對象 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快捷登錄,其實很簡單的,大家可以試一試。
還有什麼不清楚的,可以看看官方介紹,更詳細,
Tips:如何在本地測試QQ快速登錄
方法:修改HOST配置文件
1. 打開C:\Windows\System32\drivers\etc\host
2. 添加127.0.0.1 www.test.com
然後操作就可以了。
以上就是本文的全部內容,希望對大家的學習有所幫助,也希望大家多多支持。
