使用Python的BaseHTTPServer将POST请求中的文件保存到磁盘，而无需存储在内存中

import os
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer

class RequestHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        content_length = int(self.headers['Content-Length'])
        file_data = self.rfile.read(content_length)

        # 获取文件名
        file_name = self.headers['filename']

        # 保存文件到磁盘
        with open(file_name, 'wb') as file:
            file.write(file_data)

        self.send_response(200)
        self.end_headers()
        self.wfile.write('File saved successfully.')

def run(server_class=HTTPServer, handler_class=RequestHandler, port=8000):
    server_address = ('', port)
    httpd = server_class(server_address, handler_class)
    print('Starting server on port %d...' % port)
    httpd.serve_forever()

run()
