视频在线播放源码通常包括前端播放器、后端服务器和流媒体协议。
创建一个在线视频播放平台需要处理多个方面，包括前端界面、后端服务、数据库和视频文件的存储与管理，这里我们使用HTML, CSS, JavaScript来构建前端，Node.js和Express框架来构建后端，MongoDB作为数据库，以及使用AWS S3来存储视频文件。
1. 环境准备
确保你已经安装了以下工具：
Node.js 和 npm
MongoDB
AWS CLI（用于上传视频文件到S3）
2. 项目结构
videoplayer/ ├── public/ │ ├── index.html │ ├── style.css │ └── app.js ├── server/ │ ├── server.js │ ├── routes/ │ │ └── video.js │ ├── controllers/ │ │ └── videoController.js │ ├── models/ │ │ └── videoModel.js │ └── package.json ├── .env └── package.json
3. 前端部分
public/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF8">
<title>Online Video Player</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Video List</h1>
<div id="app"></div>
<script src="app.js"></script>
</body>
</html> public/style.css
body {
fontfamily: Arial, sansserif;
}
#app {
display: flex;
flexdirection: column;
alignitems: center;
}
video {
width: 60%;
margintop: 20px;
} public/app.js
document.addEventListener("DOMContentLoaded", function() {
fetch('/api/videos')
.then(response => response.json())
.then(data => {
let videoList = document.getElementById('app');
data.forEach(video => {
let videoElement = document.createElement('video');
videoElement.src = video.url;
videoElement.controls = true;
videoList.appendChild(videoElement);
});
})
.catch(error => console.error('Error fetching videos:', error));
}); 4. 后端部分
server/server.js
const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('bodyparser');
const cors = require('cors');
require('dotenv').config();
const app = express();
const port = process.env.PORT || 3000;
app.use(cors());
app.use(bodyParser.json());
// Connect to MongoDB
mongoose.connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
.then(() => console.log('MongoDB connected'))
.catch(err => console.log(err));
// Routes
app.use('/api', require('./routes/video'));
app.listen(port, () => {
console.log(Server running on port ${port});
}); server/package.json
{
"name": "videoplayer",
"version": "1.0.0",
"main": "server.js",
"dependencies": {
"express": "^4.17.1",
"mongoose": "^5.12.3",
"bodyparser": "^1.19.0",
"cors": "^2.8.5",
"dotenv": "^8.2.0"
}
} server/routes/video.js
const express = require('express');
const router = express.Router();
const videoController = require('../controllers/videoController');
router.get('/', videoController.getAllVideos);
router.post('/', videoController.uploadVideo);
module.exports = router; server/controllers/videoController.js
const Video = require('../models/videoModel');
const aws = require('awssdk');
const fs = require('fs');
const path = require('path');
const dotenv = require('dotenv');
dotenv.config();
const s3 = new aws.S3({
accessKeyId: process.env.AWS_ACCESS_KEY,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
});
exports.getAllVideos = async (req, res) => {
try {
const videos = await Video.find();
res.status(200).json(videos);
} catch (error) {
res.status(500).json({ message: 'Error fetching videos' });
}
};
exports.uploadVideo = async (req, res) => {
const file = req.files.file;
const fileStream = fs.createReadStream(file.path);
const uploadParams = {
Bucket: process.env.AWS_BUCKET_NAME,
Key: file.originalname, // Use a unique name for the key to avoid overwriting files with the same name
Body: fileStream,
};
return s3.upload(uploadParams, (err, data) => {
if (err) {
return res.status(500).json({ message: 'There was an error uploading your file' });
} else {
const newVideo = new Video({ url: data.Location });
newVideo.save()
.then(() => {
res.status(201).json({ message: 'Video uploaded successfully' });
})
.catch(err => res.status(500).json({ message: 'There was an error saving the video to the database' }));
}
});
}; server/models/videoModel.js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const VideoSchema = new Schema({
url: { type: String, required: true },
});
module.exports = mongoose.model('Video', VideoSchema); 5. 配置环境变量.env 文件内容示例：
MONGO_URI=mongodb://localhost:27017/videoplayer AWS_ACCESS_KEY=youraccesskeyid AWS_SECRET_ACCESS_KEY=yoursecretaccesskey AWS_BUCKET_NAME=yourbucketname PORT=3000
6. 安装依赖并运行服务器
在server 目录下运行：
npm install node server.js
在浏览器中访问http://localhost:3000，你应该会看到视频列表页面，可以使用Postman或者Insomnia等API测试工具向http://localhost:3000/api/video 发送POST请求，上传视频文件进行测试。
