How to use PHP to call the Kuaishou API interface to obtain and process user information

As a popular short video social platform in China, Kuaishou has a huge user base and rich content resources. When developing related to Kuaishou, many developers will use Kuaishou's API interface to obtain and process user information. This article will introduce how to use PHP to call the Kuaishou API interface to quickly and accurately obtain user information and process it.

1. Apply for a Kuaishou developer account
Before using the Kuaishou API interface, you need to apply for a Kuaishou developer account and create an application to obtain the information required to access the API, including App ID and App Secret.

2. Obtain Access Token
In order to access Kuaishou’s API interface, you need to obtain the Access Token first. Access Token is a token used to verify the developer's identity and is generally valid for 30 days. There are two ways to obtain Access Token: one is to obtain it through user name and password, and the other is to obtain it through App ID and App Secret.

The following is a sample code to obtain Access Token through 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'];
?>

3. Obtain user information
After obtaining Access Token, you can use it to obtain user information . By calling Kuaishou's user information interface, you can obtain the user's basic information, watch list, fan list, etc. The URL of the interface is as follows:

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

Among them, {access_token} is the obtained Access Token, and {open_id} is the user's unique identifier.

The following is a sample code for obtaining user information:

<?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);
?>

4. Processing user information
After obtaining user information, it can be processed according to needs. For example, the user's nickname, avatar, number of fans and other information can be obtained and displayed or stored. The following is a simple example showing how to process user information:

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

// 在这里可以进行进一步的处理，例如展示用户信息、保存用户信息到数据库等
?>

Through the above steps, you can call Kuaishou's API interface in PHP to obtain user information and process it. In actual applications, different API interfaces can be called according to specific needs to achieve richer functions.

Summary
This article introduces how to use PHP to call the Kuaishou API interface to obtain and process user information. By applying for a Kuaishou developer account, obtaining Access Token, calling the user information interface and processing user information, developers can flexibly apply the API interface provided by Kuaishou in their own applications to achieve more interesting functions. I hope this article will be helpful to developers who are developing Kuaishou!
