With the development of the Internet, people's demand for data storage and sharing is increasing. As a cloud storage service, personal network disk can conveniently store and share personal data, such as documents, pictures, videos, etc. This article will introduce how to use the Vue framework to develop a personal network disk video storage interface to realize functions such as video upload, display, playback, deletion, training, and cross-modal retrieval.
function points
1. Video upload: Users can upload videos to their personal network disk. They need to enter the video name, short description notes, and the upload time will be displayed after uploading.
2. Video display: display the video list similar to station b, and each video will display information such as name, description, upload time and so on.
3. Video playback: users can play videos on the interface.
4. Video deletion: Users can delete their own uploaded videos.
5. Video training: Users can select a video for training, and a model file will be generated after training.
6. Cross-modal search: Users can select a video for cross-modal search, and the search results will be displayed on the interface.
7. Video search: Users can search for videos by video name and display the search results.
Interface Implementation Ideas
1. Video upload: Use the Vue component to implement the upload form, send a POST request to the backend through the axios library, and upload the video file and related information to the server.
2. Video display: Use the Vue component to implement the video list, send a GET request to the backend through the axios library, obtain the video list data, and display it on the interface.
3. Video playback: use the Vue component to implement the video player, and implement the video playback function through the video tag.
4. Video deletion: Use the Vue component to implement the delete button, send a DELETE request to the backend through the axios library, and delete the video file on the server.
5. Video training: Use the Vue component to implement the training button, send a POST request to the backend through the axios library, train the video file on the server, and generate a model file.
6. Cross-modal retrieval: Use Vue components to implement the retrieval button, send a POST request to the backend through the axios library, retrieve video files on the server, and display the retrieval results.
7. Video search: Use Vue components to implement the search box and search button, send a GET request to the backend through the axios library, obtain the search results, and display them on the interface.
Interface implementation code
1. Video upload component:
```
<template>
<div>
<form @submit.prevent="uploadVideo">

Interface for interacting with the backend
1. Video upload interface:
```
router.post('/api/uploadVideo', upload.single('videoFile'), (req, res) => {
const { videoName, videoDesc } = req.body;
const videoPath = req.file.path;
const uploadTime = new Date().toLocaleString();
// Store the video information to the database
// ...
res.send('uploaded successfully');
});
```
2. Video display interface:
```
router.get('/api/getVideoList', (req, res) => { // Get video list data from the database // ...
res.send(videoList);
});
```
3. Video playback interface:
```
router.get('/api/getVideo', (req, res) => {
const videoPath = 'path/to/video.mp4';
const stat = fs.statSync(videoPath);
const fileSize = stat.size;
const range = req.headers.range;
if (range) {
const parts = range.replace(/bytes=/, '').split('-');
const start = parseInt(parts[0], 10);
const end = parts[1] ? parseInt(parts[1], 10) : fileSize - 1;
const chunkSize = end - start + 1;
const file = fs.createReadStream(videoPath, { start, end });
const head = {
'Content-Range': `bytes ${start}-${end}/${fileSize}`,
'Accept-Ranges': 'bytes',
'Content-Length': chunkSize,
'Content-Type': 'video/mp4',
};
res.writeHead(206, head);
file.pipe(res);
} else {
const head = {
'Content-Length': fileSize,
'Content-Type': 'video/mp4',
};
res.writeHead(200, head);
fs.createReadStream(videoPath).pipe(res);
}
});
```
4. Video delete interface:
```
router.delete('/api/deleteVideo/:id', (req, res) => {
const videoId = req.params.id;
// delete video info from database
// ...
res.send('deleted successfully');
});
```
5. Video training interface:
```
router.post('/api/trainVideo/:id', (req, res) => {
const videoId = req.params.id;
// Get the video path from the database
// ...
// call the training interface training video
// ...
res.send('Training succeeded');
});
```
6. Cross-modal retrieval interface:
```
router.post('/api/searchVideo/:id', (req, res) => {
const videoId = req.params.id;
// Get the video path from the database
// ...
// Call the retrieval interface to retrieve the video
// ...
res.send(searchResult);
});
```
7. Video search interface:
```
router.get('/api/searchVideo', (req, res) => {
const searchText = req.query.searchText;
// Search video information from the database
// ...
res.send(searchResult);
});
```
Summarize
This article introduces how to use the Vue framework to develop a personal network disk video storage interface to realize functions such as video upload, display, playback, deletion, training, and cross-modal retrieval. Through the cooperation of front-end components and back-end interfaces, a complete video storage and management system is realized. At the same time, this article also introduces some commonly used technologies, such as Vue framework, axios library, Node.js and Express framework, etc., which have certain reference value for front-end and back-end developers.
