使用Flask上传多个文件

from flask import Flask, request, render_template
import os

app = Flask(__name__)

@app.route('/upload', methods=['GET', 'POST'])
def upload_file():
    if request.method == 'POST':
        files = request.files.getlist('file[]')
        for file in files:
            filename = file.filename
            file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
        return '文件上传成功'
    return render_template('upload.html')

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