Teach you how to use PHP to connect to the QQ interface and implement user information query

With the rapid development of the Internet, third-party login has become one of the essential functions in various websites and applications. Users can quickly log in through a third-party account, saving registration time and effort. As one of the largest instant messaging tools in China, QQ login has also become the first choice for many websites and applications.

In order to implement the QQ login function, we can connect through the QQ interface. In PHP, we can use some open source libraries and classes to implement the docking function. Next, I will teach you how to use PHP to connect to the QQ interface and implement user information query.

1. Register a developer account

First, we need to register a developer account on the QQ open platform. Open the official website of QQ Open Platform (https://open.qq.com/), click the "Apply to Become a Developer" button in the upper right corner, and then follow the prompts to fill in the relevant information for account registration and authentication.

After registration is completed, log in to the QQ Open Platform, click "Application Management" in the left menu, and then click the "Create Application" button in the upper right corner. After filling in the application-related information and submitting it, we can obtain an App ID and App Key, which will be used in subsequent development.

2. Download and configure the open source library

Next, we need to download and configure an open source library for connecting to the QQ interface. Here I recommend using "php-sdk", a simple and easy-to-use PHP open source library.

Open the official website of GitHub (https://github.com/) and search for "php-sdk" and find the "QC.Login" project in the search results. Click to enter the project page, and then click the "Download" button in the upper right corner to download the source code.

Extract the downloaded source code into your project directory, and then open the "config.inc.php" file for configuration. In the file, find the following code:

$_CONFIG['appid'] = 'YOUR_APPID';
$_CONFIG['appkey'] = 'YOUR_APPKEY';

Replace "YOUR_APPID" with the App ID you obtained on the QQ Open Platform, and replace "YOUR_APPKEY" with your App Key. Save and close the file.

3. Implement user information query

Now that we have completed the configuration of the development environment, we can start to implement the user information query function.

First, create a QQ login entry page in your website or application. After the user clicks on the entrance page, we will jump to the QQ login page.

Add the following code to the entry page:

require_once("YOUR_SDK_PATH/QC.Class.php");
$_SESSION["state"] = md5(uniqid(rand(), TRUE));
$_SESSION["qq_oauth_state"]=$_SESSION["state"];  // 将state值存入session
$qqlogin = new QC();
$qqlogin->qq_login();

Among them, "YOUR_SDK_PATH" needs to be replaced with the storage path of your "php-sdk" source code.

In this code, we first introduced the "QC.Class.php" file, then generated a random state value and saved it in the session. Finally, the "qq_login" method is called to implement the function of jumping to the QQ login page.

When the user completes the login on the QQ login page, QQ will call back the callback address we set in advance. In the callback address, we can obtain the user's authorization information and call the interface to obtain the user's basic information.

Add the following code to the callback address page:

require_once("YOUR_SDK_PATH/QC.Class.php");
$qqlogin = new QC();
$access_token = $qqlogin->qq_callback();
$open_id = $qqlogin->get_openid();
$qq_user_info = $qqlogin->get_user_info();

Among them, "access_token" represents the access token, "open_id" represents the user's unique identifier, and "qq_user_info" is the user's basic information. information.

Now, we have successfully obtained the user’s basic information. Next, we can perform corresponding processing according to actual needs, such as storing the user's information in the database, or directly displaying it to the user.

This concludes the article that teaches you how to use PHP to connect to the QQ interface and implement user information query. Through the above examples, you can extend and modify them according to your actual needs to achieve richer functions.

I hope this article will be helpful for you to learn how to connect PHP to the QQ interface and implement user information query. I wish you a smooth development!
