Session Recording Playback Module
FastAPI Endpoint
This endpoint retrieves past classroom sessions and allows playback of recordings.
# src/api/sessions.py
from fastapi import APIRouter, Depends, HTTPException
from typing import List
from pydantic import BaseModel
from database import get_db
import models
router = APIRouter()
class Session(BaseModel):
id: str
title: str
instructor: str
date: str
duration: str
recording_url: str
@router.get("/sessions", response_model=List[Session])
async def get_sessions(db=Depends(get_db)):
"""Get all past sessions with their details and playback URLs."""
try:
sessions = await db.query(models.Session).all()
return sessions
Node.js Endpoint
This is a Node.js alternative implementation of the same functionality.
// src/api/sessions.js
const express = require('express');
const router = express.Router();
const Joi = require('joi');
const sessionSchema = Joi.object({
id: Joi.string().required(),
title: Joi.string().required(),
instructor: Joi.string().required(),
date: Joi.string().required(),
duration: Joi.string().required(),
recording_url: Joi.string().uri().required()
});
router.get('/sessions', async (req, res) => {
try {
const sessions = await db.query(models.Session).all();
res.status(200).json(sessions);
} catch (error) {
res.status(500).send('Error retrieving sessions');
}
});
React UI Component
This component displays a list of past sessions with playback functionality.
// src/components/SessionsPlayer.js
import React, { useState, useEffect } from 'react';
import MediaPlayer from 'react-media-player';
const SessionsPlayer = ({ sessions }) => {
const [selectedSession, setSelectedSession] = useState(null);
useEffect(() => {
if (sessions.length > 0) {
setSelectedSession(sessions[0]);
}
}, [sessions]);
return (
<div className="sessions-container">
<h1>Classroom Sessions</h1>
<div className="session-list">
{sessions.map(session => (
<div
key={session.id}
className={`session-item ${selectedSession?.id === session.id ? 'active' : ''}`}
onClick={() => setSelectedSession(session)}
>
<h3>{session.title}</h3>
<p>Instructor: {session.instructor}</p>
<p>Date: {session.date}</p>
</div>
))}
</div>
{selectedSession && (
<div className="player-container">
<MediaPlayer
src={selectedSession.recording_url}
customAdditionalControls={[
{
id: 'quality',
label: 'Quality',
value: ['1080p', '720p', '480p'],
type: 'select'
}
]}
/>
</div>
)}
</div>
);
};
export default SessionsPlayer;
Data Schema (Pydantic)
Define the data structure for session recordings.
# src/schemas/session.py
from pydantic import BaseModel
from typing import Optional
class Session(BaseModel):
id: str
title: str
instructor: str
date: str
duration: str
recording_url: str
class Config:
orm_mode = True
Summary
This module provides a robust way to access and replay past classroom sessions through a FastAPI or Node.js endpoint, with配套 React UI for playback. The Pydantic schema ensures data consistency and validation.
