Guide to Managing User Follows and Fans Using PHP with Kuaishou API

Managing User Follows and Fans via PHP and Kuaishou API

Introduction

With the rise of short video platforms, Kuaishou has become a popular social tool. As developers, we can leverage PHP to call Kuaishou’s open API to easily implement user follow and fan management features. This article will guide you through these operations with practical code examples.

Obtaining User Authorization

Before accessing Kuaishou user data, it is necessary to obtain user authorization. Users need to authorize third-party applications to access their Kuaishou accounts through the OAuth 2.0 mechanism. The steps are as follows:

• Register an app on Kuaishou Open Platform to get the App Key and App Secret.
• Create an authorization URL including app info and scope of access.
• Users click the link to log in and authorize their Kuaishou account.
• Kuaishou redirects to the callback URL with an authorization code.
• Use the authorization code to request an access token and save it for later use.

The following sample code demonstrates how to build the authorization URL and handle the callback:

<?php
$client_id = 'your_app_key';
$client_secret = 'your_app_secret';
$redirect_uri = 'your_callback_url';

// Build authorization URL
$auth_url = 'https://open-api.kuaishou.com/oauth2/authorize?';
$auth_url .= 'client_id=' . $client_id;
$auth_url .= '&response_type=code';
$auth_url .= '&redirect_uri=' . urlencode($redirect_uri);
$auth_url .= '&scope=user_info,followers';

// Callback handling
if (isset($_GET['code'])) {
    $code = $_GET['code'];

    // Request access token
    $token_url = 'https://open-api.kuaishou.com/oauth2/access_token?';
    $token_url .= 'client_id=' . $client_id;
    $token_url .= '&client_secret=' . $client_secret;
    $token_url .= '&grant_type=authorization_code';
    $token_url .= '&code=' . $code;
    $token_url .= '&redirect_uri=' . urlencode($redirect_uri);

    $response = file_get_contents($token_url);
    $result = json_decode($response, true);

    // Save access token
    $access_token = $result['access_token'];
    // It is recommended to store the token in a database or cache for future API calls
}
?>

Retrieving User Followings

By calling Kuaishou’s user/following endpoint, developers can query the list of users followed by a specified user. This requires a valid access token and the user ID. Sample code:

<?php
$access_token = 'your_access_token';
$user_id = 'your_user_id';

$following_url = 'https://open-api.kuaishou.com/v1/user/following?';
$following_url .= 'access_token=' . $access_token;
$following_url .= '&user_id=' . $user_id;

$response = file_get_contents($following_url);
$result = json_decode($response, true);

// Process following list data
// ...
?>

Retrieving Fan List

Similarly, you can call the user/follower endpoint to get a user's fans. Here is an example:

<?php
$access_token = 'your_access_token';
$user_id = 'your_user_id';

$follower_url = 'https://open-api.kuaishou.com/v1/user/follower?';
$follower_url .= 'access_token=' . $access_token;
$follower_url .= '&user_id=' . $user_id;

$response = file_get_contents($follower_url);
$result = json_decode($response, true);

// Process fan data
// ...
?>

Conclusion

This article introduced how to use PHP to interact with Kuaishou API for managing user follows and fans, including OAuth authorization and example API calls. Developers can build on this foundation to create richer and more functional Kuaishou applications tailored to diverse needs.
