消息：不支持的方法（'POST'）。错误 501 蟒蛇

Question

我正在尝试在 udacity 在线学院学习一些 Http Server。问题是以下代码触发了错误消息：不支持的方法（'POST'）。错误 501 Python：

from http.server import HTTPServer, BaseHTTPRequestHandler
from urllib.parse import parse_qs


class MessageHandler(BaseHTTPRequestHandler):
    def do_POST(self):
        # 1. How long was the message?
        length = int(self.headers.get('Content-length', 0))

        # 2. Read the correct amount of data from the request.
        data = self.rfile.read(length).decode()

        # 3. Extract the "message" field from the request data.
        message = parse_qs(data)["message"][0]

        # Send the "message" field back as the response.
        self.send_response(200)
        self.send_header('Content-type', 'text/plain; charset=utf-8')
        self.end_headers()
        self.wfile.write(message.encode())


if __name__ == '__main__':
    server_address = ('', 8000)
    httpd = HTTPServer(server_address, MessageHandler)
    httpd.serve_forever()

哪个Python？你的代码是正确的。立即测试，它发送响应。

我所做的唯一修改是

#message = parse_qs(data)["message"][0]
message = 'hello'

客户端代码：

import requests
res = requests.post('http://localhost:8000/abc', data = {'key':'value'})
print(res)

客户端得到200响应
