简洁明了，直接上代码吧
1. Flask实现文件上传
import osfrom flask import jsonifyfrom flask import request@app.route(‘/upload‘, methods=["POST"])def upload_file(): ???try: ???????handle_upload() ???except Exception as e: ???????return build_response(500, "Server error", None) ???return build_response(200, None, None)def handle_upload(): ???file = request.files[‘file‘] ???path = os.path.join("/Users/master/uploads", file.filename) ???file.save(path)def build_response(code, msg, data): ???res = { ???????"code": code ???} ???if code != 200: ???????res["msg"] = msg ???else: ???????res["data"] = data ???return jsonify(res) ???2. Flask实现文件下载
# coding:utf-8import osfrom flask import jsonifyfrom flask import send_from_directory@app.route(‘/download‘, methods=["POST"])def download_report(): ???try: ???????dir_path = os.path.join("/Users/master", ‘uploads‘) ???????file_name = "test.csv" ???????return send_from_directory(dir_path, file_name, as_attachment=True) ???except Exception as e: ???????return build_response(500, "Server error", None) ???return build_response(200, None, None)def build_response(code, msg, data): ???res = { ???????"code": code ???} ???if code != 200: ???????res["msg"] = msg ???else: ???????res["data"] = data ???return jsonify(res)更多请关注微信公众号
