我昨天发布了一个问题： 将 python 脚本重定向到另一个 python 脚本以验证登录凭据

在我完成了那一点之后，我遇到了另一个与 cookie 有关的问题。我从 python 脚本代码中发送了标头中的 cookie：

        #Create Cookie
        C= Cookie.SimpleCookie()
        #take the value of usernameLogin into the variable username
        username= form.getvalue('usernameLogin')
        #Set-Cookie header with the usernameLogin key
        C['usernameLogin'] = username

这段代码在前面的 python 脚本validate.py中

我想将 cookie 发送到下一个脚本page1.py 这是我的page1.py代码：

import cgi
import cgitb
import sqlite3
import Cookie
import os

user_name=""
user_id=""
useridDb=""
resultid=""
resultname=""
idUser=""
if os.environ.has_key("HTTP_COOKIE"):
    C= Cookie.SimpleCookie(os.environ.get("HTTP_COOKIE",""))
    if C.has_key("usernameLogin"):
        user_name= C['usernameLogin'].value
        print user_name

form= cgi.FieldStorage()
cgitb.enable()

#Open connection
conn= sqlite3.connect("manager.db")

它打印页面，但不生成查询。是因为 cookie 没有被检索和解析，还是 SELECT 语句有问题？

我找到了答案。在之前的 validate.py 中的 header 之前没有设置 cookie
