How to Use PHP to Call the Kuaishou API to Retrieve and Process User Information

Kuaishou is one of China's leading short video social platforms with a vast user base and rich content resources. When developing related features, developers often need to call Kuaishou’s API to retrieve and handle user information. This article guides you through the process of implementing this using PHP, helping you quickly access user data and process it effectively.

Register as a Kuaishou Developer

Before calling the Kuaishou API, you must first register as a Kuaishou developer and create an application. This step provides the necessary App ID and App Secret for API access.

Obtain Access Token

Access to Kuaishou API requires an Access Token for authentication. The token is generally valid for 30 days. There are two main ways to obtain it: using username and password or using the App ID and App Secret. Below is an example of acquiring the Access Token using the App ID and App Secret:

<?php
$appId = "your_app_id";
$appSecret = "your_app_secret";

tokenUrl = "https://open.kuaishou.com/oauth2/access_token";

data = [
    "app_id" => $appId,
    "app_secret" => $appSecret,
    "grant_type" => "client_credentials"
];

$options = [
    CURLOPT_URL => $tokenUrl,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => http_build_query($data),
    CURLOPT_RETURNTRANSFER => true,
];

$curl = curl_init();
curl_setopt_array($curl, $options);
$response = curl_exec($curl);
curl_close($curl);

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

Retrieve User Information via API

Once the Access Token is obtained, you can call the user information API to fetch basic profile data, followers, and following lists. The API URL is as follows:

https://open.kuaishou.com/openapi/userinfo?access_token={access_token}&open_id={open_id}

Here, {access_token} is the token you got earlier, and {open_id} is the unique user identifier. Example code:

<?php
$openId = "user_open_id";

$userInfoUrl = "https://open.kuaishou.com/openapi/userinfo?access_token={$accessToken}&open_id={$openId}";

$options = [
    CURLOPT_URL => $userInfoUrl,
    CURLOPT_RETURNTRANSFER => true,
];

$curl = curl_init();
curl_setopt_array($curl, $options);
$response = curl_exec($curl);
curl_close($curl);

$userInfo = json_decode($response, true);
?>

Process and Use User Information

After retrieving the user information, you can display, store, or otherwise process the data as needed. Here's a simple example:

<?php
$nickname = $userInfo['user_nickname'];
$avatar = $userInfo['user_avatar'];
$followers = $userInfo['user_followers'];

// Further processing such as displaying info or saving to a database
?>

Conclusion

This article has walked you through using PHP to call the Kuaishou API, from registering as a developer, obtaining an Access Token, calling the user info API, to processing user data. Mastering these steps enables developers to leverage Kuaishou’s API flexibly and create rich interactive features that enhance app engagement and data value.
