python3部署文件服务器，支持curl命令上传文件

• 上传命令
  curl -F "file=@file.txt" http://x.x.x.x:5000/upload

• file-server.py

from flask import Flask, request, redirect, url_for, send_from_directory, flash, jsonify
import os

app = Flask(__name__)

# 设置上传文件的保存目录
UPLOAD_FOLDER = '/upload'
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER

# 确保上传目录存在
if not os.path.exists(UPLOAD_FOLDER):
    os.makedirs(UPLOAD_FOLDER)

# 允许上传的文件扩展名
ALLOWED_EXTENSIONS = {'gz', 'txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'}

def allowed_file(filename):
    return True
    #return '.' in filename and \
    #       filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS

@app.route('/upload', methods=['POST'])
def upload_file():
    # 检查请求中是否包含文件部分
    if 'file' not in request.files:
        return jsonify({'error': 'No file part'}), 400
    file = request.files['file']
    # 如果用户没有选择文件
    if file.filename == '':
        return jsonify({'error': 'No selected file'}), 400
    if file and allowed_file(file.filename):
        filename = file.filename
        file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
        return jsonify({'message': 'File successfully uploaded', 'filename': filename}), 200
    return jsonify({'error': 'File type not allowed'}), 400

# 路由以提供上传的文件（可选）
@app.route('/uploads/<filename>')
def uploaded_file(filename):
    return send_from_directory(app.config['UPLOAD_FOLDER'], filename)

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000, debug=True)
