Integrating QQ Login with PHP: Step‑by‑Step Guide

After integrating the QQ Connect platform, users can log in to your website using their QQ accounts, reducing registration friction and attracting more users.

Apply for credentials Visit the QQ Connect official site (https://connect.qq.com/index.html), register as a developer, fill in your information, and create an application to obtain the APP ID and APP Key.

Download the SDK Download the appropriate SDK from the QQ Connect wiki at http://wiki.connect.qq.com/sdk%E4%B8%8B%E8%BD%BD.

Install and configure the SDK Place the downloaded SDK in your PHP runtime environment. Access the SDK to trigger configuration prompts and view the official documentation.

Code implementation Copy the oauth folder from the SDK's example directory to the same level as your API folder, then modify the paths in callback.php and index.php to load qqContentApi.php .

Frontend page displays a QQ login link:

<code>&lt;a href="#" onclick='toQzoneLogin()'&gt;QQ登录&lt;/a&gt;</code>
<code>&lt;script type="text/javascript"&gt;</code>
<code>    var childWindow;</code>
<code>    function toQzoneLogin(){</code>
<code>        childWindow = window.open("/qq/oauth/","TencentLogin","width=450,height=320,menubar=0,scrollbars=1, resizable=1,status=1,titlebar=0,toolbar=0,location=1");</code>
<code>    }</code>
<code>    function closeChildWindow(){</code>
<code>        childWindow.close();</code>
<code>    }</code>
<code>&lt;/script&gt;</code>

Clicking the "QQ登录" link opens the QQ authorization login window.

Callback handling After a successful login, the callback interface is triggered. You can process the returned data, such as inserting it into your database or binding it to an existing account.

<code>require_once("/API/qqConnectAPI.php");</code>
<code>$qc = new QC();</code>
<code>$qc->qq_callback(); // validate returned values</code>
<code>$openid = $qc->get_openid(); // QQ assigned user ID</code>
<code>$result = $qc->get_user_info(); // retrieve user information</code>
