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")

#print excursion details
cur=conn.cursor()
resultid= cur.execute("SELECT userid FROM login WHERE username=?",[user_name])
cur.fetchone()
for data in resultid:
idUser= int(data)
resultname= cur.execute("""SELECT location,excurDate,excurTime FROM excursion WHERE user=?""",[idUser])
cur.fetchall()
for record in resultname:
print"<tr><td>",record[0],"</td><td>",record[1],"</td><td>",record[2],"</td></tr>"
print page2head
print page1foot
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？
