How to use PHP and Youpai Cloud API to implement online video playback function

With the rapid development of the Internet, video has become one of the main ways for people to obtain information and entertainment on the Internet. In order to implement the video playback function on the web page, we can use Youpaiyun's API to achieve it. This article will introduce how to use PHP and Youpai Cloud API to implement the online video playback function, and give corresponding code examples.

Youpaiyun is a well-known cloud storage and CDN service provider in China. They provide a wealth of API interfaces to meet the needs of developers, including the function of online video playback. The following are the detailed steps of the implementation process:

Step 1: Register a Youpaiyun account
First we need to register an account on the Youpaiyun official website and create a space to store our video files. After the registration is completed, you can obtain basic API information through Youpaiyun's console, including space name, operator name, operator password, etc.

Step 2: Upload video files
After creating the space on Youpaiyun's console, you can use the SDK provided by Youpaiyun or directly upload video files through the API interface. Here we assume that a video file named "example.mp4" has been uploaded.

Step 3: Generate preview address
In order to play the video on the web page, we need to generate a video address that can be parsed by the browser. Youpaiyun provides a method called "video watermark" to achieve this function. We can use Youpaiyun's API interface to generate a preview address and add a watermark image to the video. The following is a code example that uses PHP to generate a preview address:

<?php

// 配置又拍云基本参数
$bucketName = "your_bucket_name";
$operatorName = "your_operator_name";
$operatorPassword = "your_operator_password";
$url = "http://v0.api.upyun.com/";

// 要处理的视频文件名
$videoName = "example.mp4";

// 设置视频水印的参数
$waterMark = "http://www.example.com/watermark.png"; // 水印图片地址
$position = "ne"; // 水印位置，这里使用右上角（东北方向）
$previewTime = 10; // 预览的时间（秒）

// 生成签名
$date = gmdate('D, d M Y H:i:s GMT');
$sign = md5("POST&/{$bucketName}/{$videoName}&{$date}&0&" . md5($operatorPassword));
$authHeader = array("Authorization: UPYUN {$operatorName}:{$sign}");

// 生成预览地址
$apiUrl = "{$url}{$bucketName}/{$videoName}/preview/0/{$previewTime}/{$position}/{$waterMark}";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_HTTPHEADER, $authHeader);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

$response = json_decode($result, true);

if ($response['code'] === 200) {
    $previewUrl = $response['data']['url'];
    echo "视频预览地址：" . $previewUrl;
} else {
    echo "生成预览地址失败";
}

?>

In this code, you need to replace "your_bucket_name", "your_operator_name", "your_operator_password", "http://www.example.com/ watermark.png" with the corresponding parameters.

Step 4: Display the video in the web page
Finally, we can use the HTML video tag in the web page to implement the video playback function, and use the preview address as the source of the video file. The following is a simple HTML code example:

<video src="<?php echo $previewUrl; ?>" controls autoplay></video>

In this way, when the user visits our webpage, they can see that the video corresponding to the generated video preview address is automatically played on the webpage.

Summary
By using PHP and Youpai Cloud API to implement the online video playback function, we can easily display video content on web pages. You only need to register a Youpaiyun account, upload video files, generate a preview address, and then add the corresponding HTML code to the web page. In this way, we can better attract users' attention and provide a richer web experience.
