How to implement video search and recommendation functions using PHP Kuaishou API interface

Use the PHP Kuaishou API interface to implement video search and recommendation functions

Introduction:
With the development of the Internet, the popularity of short videos has become a mainstream social media. As a well-known short video social platform in China, Kuaishou has attracted a large number of users. When developing Kuaishou-related applications or websites, video search and recommendation functions can be implemented by using the Kuaishou API interface. This article will introduce how to use PHP to write code and call the Kuaishou API interface to implement video search and recommendation functions.

1. Obtain the identity authentication information of the Kuaishou API interface
Before starting to use the Kuaishou API interface, you need to obtain the identity authentication information of the interface. The specific steps are as follows:

1. Register as a Kuaishou developer and create an application;
2. Obtain the AppKey and AppSecret of the application on the Kuaishou developer platform;
3. Generate based on the AppKey and AppSecret Identity authentication information, get an access_token.

2. Implementation of the video search function
The steps to use the Kuaishou API interface to implement the video search function are as follows:

1. Construct the request URL

$url = "https://open.kuaishou.com/rest/search/searchFeed?search={$keyword}&page=1&count=10";

Among them, $keyword is the keyword to be searched, and limit is the number of videos to be returned.

2. Send HTTP request and process the returned results

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
if(curl_errno($ch)){
    echo 'Error: '.curl_error($ch);
}
curl_close($ch);

// 解析返回的JSON数据
$data = json_decode($result, true);

3. Parse the returned JSON data

if($data['result'] == 'success'){
    $videos = $data['feeds'];
    foreach($videos as $video){
        echo "视频标题：" . $video['caption'] . "<br/>";
        echo "视频封面：" . $video['cover']['path'] . "<br/>";
        echo "视频地址：" . $video['main_mv_url'] . "<br/>";
        echo "<hr/>";
    }
}else{
    echo "视频搜索失败";
}

Among them, $data['feeds'] is the search result, including information such as the title, cover, and address of the video.

3. Implementation of the video recommendation function
The steps to use the Kuaishou API interface to implement the video recommendation function are as follows:

1. Construct the request URL

$url = "https://open.kuaishou.com/rest/recommend/feed?feedType=[1/2/3/...] &page=1&count=10";

Among them, feedType represents Recommended video type, available values ​​are 1, 2, 3, etc.

2. Send an HTTP request and process the return result. The specific code is as shown in the second step.

3. Parse the returned JSON data

if($data['result'] == 'success'){
    $videos = $data['feeds'];
    foreach($videos as $video){
        echo "视频标题：" . $video['caption'] . "<br/>";
        echo "视频封面：" . $video['cover']['path'] . "<br/>";
        echo "视频地址：" . $video['main_mv_url'] . "<br/>";
        echo "<hr/>";
    }
}else{
    echo "视频推荐失败";
}

Summary:
By using PHP to call the Kuaishou API interface, we can implement the search and recommendation functions of Kuaishou videos. During use, you need to pay attention to obtaining the correct identity authentication information, constructing the request URL, obtaining the returned JSON data through HTTP requests, and finally parsing and displaying it. The above is the method and sample code for using PHP to implement Kuaishou video search and recommendation functions. Hope this article is helpful to you!
