How to use PHP and Youpai Cloud API to implement live video function

Nowadays, with the continuous development and popularization of network technology, live video has become one of the important ways for people to obtain information and entertainment. . As a scripting language widely used in web development, PHP, combined with Youpaiyun API, can help us easily implement the function of live video streaming.

Youpaiyun is a well-known cloud storage and content distribution network (CDN) service provider that provides related functions and APIs for live video broadcasts. Its services are stable and reliable and its technical support is complete, making it very suitable for building videos. Live streaming platform.

This article will introduce how to use PHP and Youpai Cloud API to implement video live broadcast functions, including creating channels, generating push address, pushing and playing videos, etc. The following are specific steps and code examples:

1. Register Youpaiyun account and obtain API key
   First, you need to register an account on Youpaiyun official website and obtain API key. The API key is an important credential for calling Youpai Cloud API, ensuring it is used correctly in the code.

2. Create channel
   On the live broadcast platform, we first need to create a channel to host the live video stream. Channel creation can be completed by calling Youpaiyun's API.

   <?php
   $apiUrl = 'https://api.upyun.com/';
   $apiKey = 'YOUR_API_KEY';
   $apiSecret = 'YOUR_API_SECRET';
   
   // 请求参数
   $params = [
       'service' => 'live',
       'type' => 'push',
       'app' => 'live',
       'name' => 'channel_name'
   ];
   
   // 生成签名
   $sign = md5(json_encode($params) . $apiSecret);
   
   // 发送请求
   $response = file_get_contents($apiUrl . 'create/channels?' . http_build_query($params) . '&sign=' . $sign);
   
   // 显示返回结果
   echo $response;
   ?>

   In the above code, you need to replace YOUR_API_KEY and YOUR_API_SECRET with your own API key. Then modify channel_name as needed to the name of the channel you want to create.

3. Generate push address
   After the channel is successfully created, we need to generate a push address to push the video stream to Youpaiyun's server. Similarly, we can achieve this by calling Youpaiyun's API.

   <?php
   $apiUrl = 'https://api.upyun.com/';
   $apiKey = 'YOUR_API_KEY';
   $apiSecret = 'YOUR_API_SECRET';
   
   // 请求参数
   $params = [
       'service' => 'live',
       'type' => 'push',
       'app' => 'live',
       'name' => 'channel_name',
       'expire' => time() + 3600, // 过期时间设定为1小时后
       'nonce' => uniqid() // 随机字符串，用于防止重放攻击
   ];
   
   // 生成签名
   $sign = md5(json_encode($params) . $apiSecret);
   
   // 发送请求
   $response = file_get_contents($apiUrl . 'get/streamUrls?' . http_build_query($params) . '&sign=' . $sign);
   
   // 解析返回结果
   $result = json_decode($response, true);
   
   // 显示推流地址
   echo $result['data']['rtmp'];
   ?>

   Also need to replace YOUR_API_KEY and YOUR_API_SECRET with your own API key. Modify channel_name to the channel name you created previously.

4. Pushing and playing videos
   After obtaining the push address, we can use any video push tool to push, such as OBS, etc. To play videos, you can use the HTML5 <video> tag.

   <?php
   $rtmpUrl = 'YOUR_RTMP_URL'; // 替换为你自己的推流地址
   ?>
   
   <!-- 推流 -->
   <object width="640" height="480">
       <param name="movie" value="player.swf"/>
       <param name="allowFullScreen" value="true"/>
       <param name="flashvars" value="rtmp_url=<?php echo $rtmpUrl; ?>"/>
       <object type="application/x-shockwave-flash" data="player.swf" width="640" height="480">
           <param name="allowFullScreen" value="true"/>
           <param name="flashvars" value="rtmp_url=<?php echo $rtmpUrl; ?>"/>
           <div>
               <h1>视频播放需要启用Flash Player，请点击 <a href="http://www.adobe.com/go/getflashplayer">这里</a>下载最新版本。</h1>
           </div>
       </object>
   </object>
   
   <!-- 播放 -->
   <video width="640" height="480" controls>
       <source src="<?php echo $rtmpUrl; ?>" type="video/rtmp">
       您的浏览器不支持HTML5 video标签。
   </video>

   Replace YOUR_RTMP_URL with the push address you obtained before.

Through the above steps, we have successfully implemented the video live broadcast function using PHP and Youpai Cloud API. Of course, this is just a simple example and you can extend and improve the code according to your needs. I hope this article will be helpful to your development work!
