如何满足一些条件时执行另一个Python程序？ [英] How to execute another python program when some condition is met?
问题描述
这是validate.py
导入cgi
导入yate
导入sqlite3
connection = sqlite3.connect（'users.sqlite'）
cursor = connection.cursor（）
print（yate.start_response（'text / plain'））
form = cgi.FieldStorage（）
for form_keys（）中的each_form_item：
if（each_form_item =='username'）：
username = form [each_form_item] .value
if （each_form_item =='password'）：
password = form [each_form_item] .value
result = cursor.execute（'SELECT USERNAME from validate'）
usernames = [row用于用户名中的每个用户名的
：
if（username == each_username）：
pass_result = cursor.execute（'SELECT PASSWORD from validate where username =''（each_username，））
password1 = [row [0] for pass_result.fetchall（）]
for password1中的each_password：
if（each_password == password）：
print（'登录成功'）
＃希望运行另一个python程序，例如welcome.py
else：
print（'Login Failure'）
Web服务器正在后台运行。如果上述代码中的条件为真，我想要网页重定向到另一个python程序。我怎么做？

当我点击提交按钮validate.py运行。现在，如果用户名和密码匹配，我希望网络浏览器自动将浏览器重定向到另一个py文件或html页面，而无需用户执行任何操作。
编辑2 ：
我使用的是一个python服务器，其代码为：
从http.server导入HTTPServer，CGIHTTPRequestHandler
port = 8080
httpd = HTTPServer（（''，port），CGIHTTPRequestHandler）
print（Starting simple_httpd on port：+ str（httpd.server_port））
httpd.serve_forever（）
使用命令提示符运行。然后使用localhost：8080在Web浏览器中打开索引页。 使用 execfile 命令：
用于用户名中的每个用户名：
if（username == each_username）：
pass_result = cursor.execute（'SELECT PASSWORD from validate where username =？'，（each_username，））
password1 = [row [0]用于pass_result.fetchall（）中的行）
for password中的each_password：
if（each_password == password）：
print（'Login Success'）
execfile（PATH_TO_THE_FILE +./ welcome.py）
else：
print（'登录失败'）
注意： PATH_TO_THE_FILE 是您的磁盘中的路径，它应该是一个字符串
编辑
你是 使用python 3x，这里是 execfile 命令的替代：
f：
code = compile（f.read（），welcome.py，'exec'）
exec（代码）带有开放（welcome.py
This is validate.py
import cgi
import yate
import sqlite3
connection = sqlite3.connect('users.sqlite')
cursor = connection.cursor()
print(yate.start_response('text/plain'))
form=cgi.FieldStorage()
for each_form_item in form.keys():
if (each_form_item=='username'):
username=form[each_form_item].value
if (each_form_item=='password'):
password=form[each_form_item].value
result=cursor.execute('SELECT USERNAME from validate')
usernames=[row[0] for row in result.fetchall()]
for each_username in usernames:
if (username==each_username):
pass_result=cursor.execute('SELECT PASSWORD from validate where username=?',(each_username,))
password1=[row[0] for row in pass_result.fetchall()]
for each_password in password1:
if (each_password==password):
print('Login Success')
#Here want to run another python program eg welcome.py
else:
print('Login Failure')
The web server is running in the background. I want to webpage to redirect to another python program if the condition in the above code is true. How do I do that?
EDIT:
Index.html
<html>
<head>
<title>Login Page</title>
<link type="text/css" rel="stylesheet" href="coach.css" />
</head>
<body>
<img src="images/logo-cel-transparent_0.png" width="74" height="64"> <strong><img src="images/logo-cel-transparent_0.png" alt="Cel logo" width="74" height="64" align="right">
</strong>
<h1 align="center"><strong>Central Electronics Limited</strong></h1>
<p> </p>
<h2 align="center">Storage Management System</h2>
<p> </p>
<p align="center">Login to System</p>
<p align="center"> </p>
<form action="/cgi-bin/validate.py" method="post">
<div align="center">User name :
<input type="text" name="username" value=""> <br>
Password : <input type="text" name="password" value=""> <br>
<input name="Submit" type="submit" value="Submit">
</div>
</form>
</body>
</html>
When i click on the submit button validate.py runs. Now if the username and password match, I want the web browser to automatically redirect the browser to another py file or html page, without the user needing to do anything.
EDIT2:
I am using a python server whose code is:
from http.server import HTTPServer, CGIHTTPRequestHandler
port = 8080
httpd = HTTPServer(('', port), CGIHTTPRequestHandler)
print("Starting simple_httpd on port: " + str(httpd.server_port))
httpd.serve_forever()
This is run using command prompt. The index page i then open in web browser using "localhost:8080".
Use the execfile command this way:
for each_username in usernames:
if (username==each_username):
pass_result=cursor.execute('SELECT PASSWORD from validate where username=?',(each_username,))
password1=[row[0] for row in pass_result.fetchall()]
for each_password in password1:
if (each_password==password):
print('Login Success')
execfile(PATH_TO_THE_FILE+"./welcome.py")
else:
print('Login Failure')
Note: PATH_TO_THE_FILE is the path in your disk and it should be a string
EDIT
As you are using python 3x, here is the alternative of execfile command:
with open("welcome.py") as f:
code = compile(f.read(), "welcome.py", 'exec')
exec(code)
