Python http server - 无法读取 cookie

Question

我已经制作了Python服务器，我想创建，发送和接收cookie。我在接收它们方面有问题，当我在Chrome上访问它时，我可以看到创建了Cookie。我读到它应该出现在OS.Environ中，但永远不会出现。这是我的代码：

import os
import time
import Cookie
import BaseHTTPServer
from multiprocessing import Process
from SocketServer import ThreadingMixIn
from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler):
    def do_GET(s):
        #creating cookie
        c = Cookie.SimpleCookie()
        c['api'] = 'token'
        c['api']['expires'] = 3*60*60
        s.send_response(200)
        #sending cookie
        s.wfile.write(c)
        s.wfile.write('rn')
        s.send_header("Access-Control-Allow-Origin", "*")
        s.send_header("Access-Control-Expose-Headers", "Access-Control-Allow-Origin")
        s.send_header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept")
        s.end_headers()
        #reading cookies
        if 'HTTP_COOKIE' in os.environ:
            cookie_string = os.environ.get('HTTP_COOKIE')
            c = Cookie.SimpleCookie()
            c.load(cookie_string)
            try:
                data=c['api'].value
                print "cookie data: "+data
            except:
                print "The cookie was not set or has expired"
        else:
            print 'The cookie was not set'

class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    ''
if __name__ == '__main__':
    httpd = ThreadedHTTPServer(('', 8666), MyHandler)
    print time.asctime(), "Server Starts - %s:%s" % (HOST_NAME, PORT_NUMBER)
    try:
        httpd.serve_forever()
    except KeyboardInterrupt:
        pass
    httpd.server_close()
    print time.asctime(), "Server Stops - %s:%s" % (HOST_NAME, PORT_NUMBER)

我访问我的网站cookie是被创建的，但是OS.Environ中从未有HTTP_COOKIE。

forFuture读者：

这是您在python3中解析cookie的方式：

from http.server import BaseHTTPRequestHandler
from http.cookies import SimpleCookie
class MyHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        cookies = SimpleCookie(self.headers.get('Cookie'))
        # then use somewhat like a dict, e.g:
        username = cookies['username'].value

回答OP的问题：

问题是您正在错误的地方寻找cookie。使用以下行，您可以在计算机的操作系统环境变量中检查一个名为 HTTP_COOKIE：

if 'HTTP_COOKIE' in os.environ:
    cookie_string = os.environ.get('HTTP_COOKIE')

但是没有理由运行Python服务器会创建操作系统宽环境变量。

相反，您必须在派生的BaseHTTPRequestHandler中查看。访问cookie的正确方法是：

cookie_string = s.headers.get('Cookie')

将解析客户端发送的标头并为您提供相应的cookie字符串。
