python的一个小web代码（Django框架下的）

2019-03-08 16:10 239 查看

[code]def login(re):
'''
登录验证
'''
nowtime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
if req.method == 'GET':
uf = UserForm()
#User.objects.create_user(username='ADMIN', password='ABC')
return render(re, 'login.html', {'uf': uf, 'nowtime': nowtime})
else:
uf = UserForm(re.POST)
if uf.is_valid():
username = re.POST.get('username', '')
password = re.POST.get('password', '')
user = auth.authenticate(username=username, password=password)
if user is not None:      #and user.is_active:
auth.login(re, user)
return render(re, 'index.html')
else:
return HttpResponse('is failed')   #render(re, 'login.html', {'uf': uf, 'nowtime': nowtime, 'password_is_wrong': True})
else:
return HttpResponse('NOT GET')  #render(re, 'login.html', {'uf': uf, 'nowtime': nowtime})

建立和mysql的数据库连接（通过调用python里面自带的auth里面的authenticate来实现）

[code]from django.db import models
from datetime import *
from django.contrib.auth.models import User
class webserver(models.Model):
user = models.OneToOneField(User, unique=True,verbose_name=('user'))
phone = models.CharField(u'phone',max_length=20)
user_role = models.CharField(u'role',max_length=40)

在类里面是必须要设置一个user类的，后端基础代码，详细注解略去

[code]# Django settings for DjangoWeb project.
import os
from django.db import models

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

DEBUG = True
# TEMPLATE_DEBUG = DEBUG

ADMINS = (
# ('Your Name', 'your_email@example.com'),
)

MANAGERS = ADMINS

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'database1',
'USER': 'root',
'PASSWORD': 'ABCabc123',
'HOST': '127.0.0.1',
'PORT': 3306,
}
}
# Hosts/domain names that are valid for this site; required if DEBUG is False
# See https://docs.djangoproject.com/en/1.4/ref/settings/#allowed-hosts
ALLOWED_HOSTS = ['*']

这部分是settings.py的连接数据库部分设置

[code]{% load staticfiles %}
<link href="{% static "css/adstyle.css"%}" rel="stylesheet" type="text/css" />
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Linux-Management</title>
</head>
{% if password.is_wrong %}
<script type="text/javascript" src="{%static "js/jquery-1.11.0.min.js" %}"></script>
<script type="text/javascript" src="{%static "js/alert.js" %}"></script>
<link href="{%static "css/alert.css" %}" rel="stylesheet" type="text/css" />
<script type="text/javascript">
Alert.showMsg("用户名或密码错误!");
location.href="/webserver/login/"
</script>
{% endif %}
<body>
<div class="admin-ht">
<div class="adminBord">
<h1>登陆</h1>
<h4>{{ nowtime }}</h4>
<form method="post" enctype="multipart/form-data" >
{% csrf_token %}
{{uf.as_p}}
<input type="submit" value="login" id="loging">
</form>
</div>
</div>
</body>
</html>

这是前端代码，login页面

[code]#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "DjangoWeb.settings")

from django.core.management import execute_from_command_line

execute_from_command_line(sys.argv)

这是manage.py代码

以上基本是这个小工程的框架结构，还有详细的例如前端技术bootstrap之类的东西现在没那么多时间去写，还有其他重要的事情需要做，这个项目的部分就写到这里。2019.3.📅
