How to realize user attention and fan management through the PHP Kuaishou API interface

Introduction:
With the development of social media, Kuaishou has become one of the most popular short video sharing platforms in China. As developers, we can implement user attention and fan management through the Kuaishou API interface to provide better user experience and social functions. This article will introduce how to use PHP language to implement these functions and provide sample code.

1. Apply for API interface permission
To use the Kuaishou API interface, you first need to apply for API interface permission on the Kuaishou open platform. Log in to the open platform, create an application and obtain the corresponding authorization information, including App Key and App Secret.

2. Obtain the access token
Using the Kuaishou API interface requires an access token (Access Token) for identity verification. In PHP, we can use cURL library to send HTTP request and get access token.

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://open.kuaishou.com/oauth2/access_token');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'app_id=YOUR_APP_ID&app_secret=YOUR_APP_SECRET');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

$jsonResponse = json_decode($response, true);
$accessToken = $jsonResponse['access_token'];
?>

In the above code, replace YOUR_APP_ID and YOUR_APP_SECRET with the application ID and application key you applied for. This interface will return a JSON formatted response from which we can extract the access token.

3. Implement the user attention function
To implement the user attention function, we can use the user/relation/set interface in the Kuaishou API. Here is a sample code:

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://open.kuaishou.com/api/user/relation/set');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'access_token=' . $accessToken . '&target=USER_ID&relation=follow');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

$jsonResponse = json_decode($response, true);
if ($jsonResponse['result'] == 'success') {
    echo '关注成功';
} else {
    echo '关注失败：' . $jsonResponse['error']['message'];
}
?>

In the above code, replace USER_ID with the ID of the user you want to follow. This interface will set the current user's attention status to the target user.

4. Implement the fan management function
To implement the fan management function, we can use the user/follower/list interface in the Kuaishou API. Here is a sample code:

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://open.kuaishou.com/api/user/follower/list');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'access_token=' . $accessToken . '&user_id=USER_ID');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

$jsonResponse = json_decode($response, true);
if ($jsonResponse['result'] == 'success') {
    $followers = $jsonResponse['followers'];
    foreach ($followers as $follower) {
        echo '粉丝ID：' . $follower['user_id'] . '，昵称：' . $follower['nickname'] . '<br>';
    }
} else {
    echo '获取粉丝列表失败：' . $jsonResponse['error']['message'];
}
?>

In the above code, replace USER_ID with the user ID you want to get the list of fans. This interface will return a JSON response containing fan information, from which we can extract the fan's user ID and nickname.

Conclusion:
By using PHP language and Kuaishou API interface, we can easily implement user attention and fan management functions. The above is a simple example, developers can expand and optimize accordingly according to their own needs and application scenarios. I hope this article can be helpful to everyone!
