登录页面和首页分开
index.html：
<html>
<head>
<title>首页</title>
</head>
<body>
<div>这是首页,当前登录用户是:<span style="color:green">{{currentuser}}</span>
</div>
</body>
</html>
userlogin.html
<style>
.bb{border:2px solid red ;width: 600px;margin: 150px auto}
.textcenter{text-align: center}
.full{width:100%}
div{line-height:40px}
.greenspan{color:green}
.redspan{color:red}
</style>
<form method="POST">
<div class="bb textcenter">
<div class="full">
请输入用户名:<input type="text" name="txtUserName"/>
</div>
<div class="full">
请输入密 码:<input type="password" name="txtUserPass"/>
</div>
<div class="full">
选择地区:<select name="userArea">
<option value="0">--请选择--</option>
{% for aa in areas %}
<option value="{{aa.id}}">{{aa.dd}}</option>
{% endfor %}
</select>
</div>
<div class="full">
<input type="submit" value="登录"/>
</div>
</div>
</form>
{{result|safe}}
urls.py
urlpatterns = [
#url(r‘^admin/‘, include(admin.site.urls)),
url(r‘^index‘,‘myindex.bb.hi‘ ),
url(r‘^login‘, ‘myindex.bb.login‘)
]
服务端代码
登陆逻辑:
UserClass.py
#coding:utf-8
class UserLogin:
UserName=""
UserPass=""
def __init__(self,uname,upass):
self.UserName=uname
self.UserPass=upass
def Login(self):
if self.UserName=="shenyi" and self.UserPass=="123":
return True
return False
业务逻辑:
如果登陆成功，就设置cookies,跳转index
# -*- coding: utf-8 -*-
from django.http.response import HttpResponse
from django.shortcuts import render_to_response
import user
from UserClass import UserLogin
def hi(request):
dataset={"result":"","currentuser":"游客"}
if request.COOKIES.get("userlogin_username") != None:
dataset["currentuser"]=request.COOKIES.get("userlogin_username")
myResponse=render_to_response("index.html",dataset)
return myResponse
def login(request):
beijin = {"id":1,"dd":"北京"}
shanghai = {"id":2,"dd":"上海"}
userAreas = [beijin,shanghai]
dataset = {‘result‘:‘‘,"areas":userAreas}
if request.method=="POST":
getUserName=request.POST.get("txtUserName");
getUserPass=request.POST.get("txtUserPass")
uLogin=UserLogin(getUserName,getUserPass)
if uLogin.Login():
myResponse=HttpResponse("<script>self.location=‘/index‘</script>")
myResponse.set_cookie("userlogin_username", getUserName, 3600) #设置cookie
return myResponse
else:
dataset["result"]="用户名和密码错误"
myResponse=render_to_response("userlogin.html",dataset)
return myResponse
from UserClass import UserLogin
为从文件中导入类
cookie
就是通过浏览器和服务器沟通后，私下保存在用户电脑里某个文件夹的一个文件。
