获取通过Python Flask App上传的文件的绝对文件名

from flask import Flask, request

app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload_file():
    file = request.files['file']
    filename = file.filename
    # 处理文件保存的逻辑
    # 返回文件的绝对文件名
    return filename

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

import os

@app.route('/upload', methods=['POST'])
def upload_file():
    file = request.files['file']
    filename = file.filename
    file.save(os.path.join('/path/to/save', filename))
    # 返回文件的绝对文件名
    return os.path.abspath(os.path.join('/path/to/save', filename))
