How to implement video playback and download using PHP Kuaishou API interface

Use PHP Kuaishou API interface to realize video playback and download

In the modern era of social entertainment, video has become an indispensable part of people's daily lives. Kuaishou is one of the most popular short video platforms in China, with a huge user base and massive amounts of high-quality content. Many developers hope to use the Kuaishou API interface to play and download Kuaishou videos in their own applications. This article will introduce how to implement this function through the PHP Kuaishou API interface and provide corresponding code examples.

First, we need to obtain the API interface key of the Kuaishou open platform. Register and log in to Kuaishou Open Platform, apply for and obtain API Key and API Secret according to the documentation. Next, we can use these keys to make API requests.

Implementing the video playback function:

<?php
// 导入必要的库
require 'vendor/autoload.php';

use GuzzleHttpClient;

// 设置API Key和API Secret
$apiKey = 'YOUR_API_KEY';
$apiSecret = 'YOUR_API_SECRET';

// 创建HTTP客户端
$client = new Client();

// 请求接口获取token
$response = $client->post('https://open-api.kuaishou.com/oauth2/access_token', [
    'form_params' => [
        'app_id' => $apiKey,
        'app_secret' => $apiSecret,
        'grant_type' => 'client_credentials',
    ],
]);

// 解析返回的数据
$tokenData = json_decode($response->getBody()->getContents(), true);

// 获取token
$token = $tokenData['access_token'];

// 根据视频id获取视频播放地址
$videoId = 'YOUR_VIDEO_ID';

$response = $client->get('https://open-api.kuaishou.com/openapi/photo/download', [
    'headers' => [
        'Authorization' => 'Bearer ' . $token,
    ],
    'query' => [
        'photoId' => $videoId,
    ],
]);

// 解析返回的数据
$videoData = json_decode($response->getBody()->getContents(), true);

// 获取视频播放地址
$videoUrl = $videoData['url'];

// 输出视频播放地址
echo $videoUrl;
?>

We first use the GuzzleHttp library to create an HTTP client, and then send a request to the token acquisition interface of the Kuaishou open platform to obtain the access token (token) . After that, we use the id of the video to call the interface for obtaining the video playback address, and send the request again to obtain the video playback address. Finally, we output the video playback address.

Implementing the video download function:

<?php
// 导入必要的库
require 'vendor/autoload.php';

use GuzzleHttpClient;

// 设置API Key和API Secret
$apiKey = 'YOUR_API_KEY';
$apiSecret = 'YOUR_API_SECRET';

// 创建HTTP客户端
$client = new Client();

// 请求接口获取token
$response = $client->post('https://open-api.kuaishou.com/oauth2/access_token', [
    'form_params' => [
        'app_id' => $apiKey,
        'app_secret' => $apiSecret,
        'grant_type' => 'client_credentials',
    ],
]);

// 解析返回的数据
$tokenData = json_decode($response->getBody()->getContents(), true);

// 获取token
$token = $tokenData['access_token'];

// 根据视频id获取视频信息
$videoId = 'YOUR_VIDEO_ID';

$response = $client->get('https://open-api.kuaishou.com/openapi/photo/get', [
    'headers' => [
        'Authorization' => 'Bearer ' . $token,
    ],
    'query' => [
        'photoId' => $videoId,
    ],
]);

// 解析返回的数据
$videoData = json_decode($response->getBody()->getContents(), true);

// 获取视频下载地址
$videoUrl = $videoData['url'];

// 下载视频文件
$file = file_get_contents($videoUrl);

// 保存视频文件
$fileName = 'video.mp4';
file_put_contents($fileName, $file);

// 输出下载成功提示
echo '视频下载成功！';
?>

Similar to the video playback function, we also obtain the token first, and then call the interface for obtaining video information to obtain the video download address. Then, use the file_get_contents function to read the video file content of the download address, and use the file_put_contents function to save it locally. Finally, a prompt that the download is successful is output.

Using the above code examples, we can easily implement the playback and download functions of Kuaishou videos through the PHP Kuaishou API interface, making our applications more diverse. Of course, the specific implementation needs to be adjusted and optimized based on the project situation. I hope this article is helpful to you, and I wish you success in implementing your video playback and download functions!
