用python代码写一个 flask_uploads插件上传图片和视频的代码

Sure, 下面是 Flask-Uploads 插件实现图片和视频上传的 Python 代码:

from flask import Flask, request
from flask_uploads import UploadSet, configure_uploads, IMAGES, VIDEOS

app = Flask(__name__)
photos = UploadSet('photos', IMAGES)
videos = UploadSet('videos', VIDEOS)

app.config['UPLOADED_PHOTOS_DEST'] = 'uploads/photos'
app.config['UPLOADED_VIDEOS_DEST'] = 'uploads/videos'
configure_uploads(app, (photos, videos))

@app.route('/upload', methods=['POST'])
def upload():
    photo_filename = ''
    video_filename = ''

    if 'photo' in request.files:
        photo = request.files['photo']
        photo_filename = photos.save(photo)

    if 'video' in request.files:
        video = request.files['video']
        video_filename = videos.save(video)

    return f"Photo file: {photo_filename} Video file: {video_filename}"

if __name__ == '__main__':
    app.run()

这段代码定义了两个 UploadSet，即 photos 和 videos，分别用于保存图片和视频。然后在 Flask 的配置中设置上传文件的保存目录，并将两个 UploadSet 配置到应用中。接着，定义了一个路由 `/upload`，当收到 POST 请求时，从请求的文件中获取图片和视频，如果存在则保存到指定的目录，并返回保存的文件名。
