“访问控制-允许-源”需要多个值

Question

我的服务器在CORS上遇到了问题，我试图包括“访问控制-允许-源”。当我运行下面的代码时，它需要另一个输入参数，即使文档显示它只需要2。#!/usr/bin/pythonimport socketserverimport socketimport http.serverimport sysHandler = http.server.SimpleHTTPRequestHandlerPort = 8005localHost = socket.gethostname()httpd = socketserver.TCPServer(("localhost", Port), Handler)Handler.send_header("Access-Control-Allow-Origin", "*")Handler.end_headers()httpd.handle_request()request = httpd.recv(1000000)httpd.serve_forever()当我运行这个，我得到以下问题： File "serverDP.py", line 29, in <module>    Handler.send_header("Access-Control-Allow-Origin", "*")TypeError: send_header() missing 1 required positional argument: 'value'我已经从这里和Github尝试了代码，但没有任何运气。感谢您的帮助。编辑我添加了一个类，现在看起来像这样：class CORSRequestHandler(http.server.SimpleHTTPRequestHandler):    def send_my_headers(self):        print("This is working :/")        self.send_header("Access-Control-Allow-Origin", "*")        http.server.SimpleHTTPRequestHandler.end_headers(self)    def end_headers(self):        self.send_my_headers()Handler = CORSRequestHandlerHandler.send_my_headers(Handler)我仍然有同样的问题。但是，我不完全确定我应该将什么传递到“Handler.send_my_headers（）”函数中

使用此代码怎么样？

#!/usr/bin/python

import socketserver

import socket

import http.server

import sys

class CORSRequestHandler(http.server.SimpleHTTPRequestHandler):

    def send_my_headers(self):

        print("This is working :/")

        self.send_header("Access-Control-Allow-Origin", "*")

        http.server.SimpleHTTPRequestHandler.end_headers(self)

    def end_headers(self):

        self.send_my_headers()

print('Server listening on port 8000...')

httpd = socketserver.TCPServer(('', 8000), CORSRequestHandler)

httpd.serve_forever()
