Teach you how to use PHP to connect to the QQ interface and implement message push

1. Introduction
With the rapid development of social networks, QQ has become a commonly used instant messaging tool for many people. For developers, obtaining users' relevant information on the QQ platform and interacting with users through messages is an important function. This article will introduce how to use PHP to connect to the QQ interface and implement the message push function.

2. Preparation work
Before we start, we need to complete the following preparation work:

1. Register a developer account on the QQ open platform, apply for an application, and obtain the AppID and AppKey.
2. Install PHP environment.

3. Introducing the QQ interface SDK
The QQ open platform provides a PHP SDK. We can simplify the process of docking the interface by introducing the SDK.

1. Download SDK file
   We can download the compressed package of PHP SDK from the official website of QQ Open Platform.
2. Extract the SDK file
   Extract the downloaded compressed package to the project folder in your local development environment. Assume that the decompressed folder is named qq_sdk.

3. Introduce QQ SDK files
   In your PHP code, use the require_once function to introduce the initialization file of QQ SDK. The code is as follows:

   require_once 'qq_sdk/qqConnectAPI.php';

   Copy after login

four , Obtain user authorization
In order to operate the user's QQ account, we need to obtain the user's authorization. The QQ open platform provides the OAuth 2.0 authorization method, which we can use the methods provided by the qqConnectAPI class to achieve this.

1. Initialize OAuth
   Call the init method of the qqConnectAPI class in the code to initialize the OAuth configuration. The code is as follows:

   $oauth = new Oauth(qq_app_id, qq_app_key);

   Copy after login

   The qq_app_id and qq_app_key here are respectively in QQ The AppID and AppKey obtained when applying for an application on the open platform.

2. Generate authorization link
   Call the getAuthorizeURL method of the qqConnectAPI class to generate an authorization link. The code is as follows:

   $redirect_url = 'http://your_own_domain.com/callback.php';
   $auth_url = $oauth->qq_login($redirect_url);

   Copy after login

   The $redirect_url here is the callback URL after the user authorization is completed. , you can define and set the correct value yourself.

3. Jump to the authorization link
   Wrap the generated authorization link with the tag, and set the href attribute to the authorization link. The code is as follows:

   <a href="<?php echo $auth_url; ?>">点击这里进行QQ授权登录</a>

   Copy after login

   After the user clicks this link, it will jump to the QQ login page for authorization.

4. Get the code returned by authorization
   After the user completes authorization on the QQ login page, he will be redirected to the set callback URL. In the callback URL page, we can obtain the Code returned by authorization through the URL parameters. The code is as follows:

   $code = $_GET['code'];

   Copy after login

5. Obtain Access Token
The Code returned by user authorization, We can get the Access Token. Call the qq_callback method of the qqConnectAPI class and pass in the Code as a parameter. The code is as follows:

$access_token = $oauth->qq_callback($code, $redirect_url);

The $redirect_url here is the callback URL set when obtaining the authorization link.

6. Obtain the user's OpenID
Through Access Token, we can obtain the user's OpenID. Call the get_openid method of the qqConnectAPI class and pass in the Access Token as a parameter. The code is as follows:

$openid = $oauth->get_openid();

7. Implement message push
After obtaining the user's OpenID, we can implement message push through the QQ interface Functional.

1. Set message content
   First, we need to set the message content to be pushed. Assume that the content of the message we want to send is "Hello, QQ!", the code is as follows:

   $message = "Hello, QQ!";

   Copy after login

2. Send message
   Call the send_feed method of the qqConnectAPI class to implement message push, the code is as follows:

   $params = array(
    'openid' => $openid,
    'con' => $message
   );
   $res = $oauth->send_feed($params);

   Copy after login
