在fastapi中的端点内创建端点

Question

假设有一个音频服务器，您可以上传歌曲、播客或有声读物。在create endpoint中，我已经创建了4个endpoint，所以我设置了一个条件，如果audio_type是一首歌，则返回该类型的所有音频，但不幸的是，这将返回null

@app.get('/audio/{audio_type}')
def show_all(audio_type):
    if audio_type == "Songs":
        @app.get("audio/song")
        def all(db: Session = Depends(database.get_db)):
            songs = db.query(models.Song).all()
            print("songs =  ", songs)
            return songs


    elif audio_type == "podcast":
        @app.get('audio/podcast')
        def all(db: Session = Depends(database.get_db)):
            podcast = db.query(models.Podcast).all()
            return podcast

    elif audio_type == "audiobook":
        @app.get('audio/audiobook')
        def all(db: Session = Depends(database.get_db)):
            audiobook = db.query(models.Audiobook).all()
            return audiobook
    else:
        raise HTTPException(status_code=status.HTTP_404_NOT_FOUND, detail=f' {audio_type} - audio type is not valid')

Answer 1

您的实现违背了API的目的。对于这样的实现，尝试将该值作为参数传递给您的API，并在此基础上将流分叉。

def all(db: Session = Depends(database.get_db), audio_type):
    if audio_type == "Songs":
        songs = db.query(models.Song).all()
        print("songs =  ", songs)
        return songs
    elif audio_type == "podcast":
        podcast = db.query(models.Podcast).all()
        return podcast
    elif audio_type == "audiobook":
        audiobook = db.query(models.Audiobook).all()
        return audiobook
    else:
        raise HTTPException(status_code=status.HTTP_404_NOT_FOUND, detail=f' {audio_type} - audio type is not valid')
    
@app.get('/audio')
def show_all(audio_type: str):
    return all(Depends(database.get_db), audio_type):
