如何在Python 3中接​​收HTML表单数据？

Question

作为项目的一部分，我试图让python接收HTML发送的表单。获取变量后，我需要python在控制台中打印“True”或“False”。这是我目前的表单HTML代码。

...
<form name = "input" action = "CheckLogin.py" method = "get">

<!-- This is the form. Here the user submits their username and password. 
The words before the colon are the words that appear on the user's screen -->

    Username: <input type = "text" name = "htmlUser">
    <br>

    Password: <input type = "password" name = "htmlPassword">
    <input type = "submit" value = "Submit">
    <br>
</form>
...

一旦我让他们提交了用户名和密码，我想使用这些数据来检查他们是否可以登录到电子邮件服务器（我在这种情况下使用了Google，但是Microsoft Server 2003不能很好地播放。）是我的Python 3脚本：

def login(username, password):
    import poplib
    try:
        server = poplib.POP3_SSL('pop.gmail.com', 995)#Weird bug here. When I use the exeter server, I am informed that the SSL number is incorrect. How do I fix?
        server.user(username)
        server.pass_(password)
        print ("True")
    except:
        print("False")

login (username, password)

我的问题是，如何让python从HTML webform获取username和password变量？

Answer 1

只需在CheckLogin.py中获取这些值并将其传递给login()：

import cgi
# ...
i = cgi.FieldStorage()
username = i["htmlUser"]
password = i["htmlPassword"]
login(username, password)
