1、django.admin.py startproject cs3
cd cs3
django.admin.py startapp blog
2、 vim urls.py
url(r'^regist/$','blog.views.regist'), 注册
url(r'^login/$','blog.views.login'), 登录
url(r'^index/$','blog.views.index'), 跳转界面
url(r'^logout/$','blog.views.logout'), 注销
)
3、vim blog/views.py
from django import forms
from django.http import HttpResponse
from django.shortcuts import render_to_response
from models import User
class UserForm(forms.Form):
username = forms.CharField()
password = forms.CharField(widget=forms.PasswordInput)
def regist(req):
if req.method == "POST":
uf = UserForm(req.POST)
if uf.is_valid():
username = uf.cleaned_data['username']
password = uf.cleaned_data['password']
User.objects.create(username=username,password=password)
return HttpResponse('ok')
else:
uf = UserForm
return render_to_response('regist.html',{'uf':uf})
4、vim blog/templates/regist.html
<form method="post">
{{uf.as_p}}
<input type="submit" value='nice'/ >
</form>
5、 python manage.py syncdb
python manage.py runserver
进入页面去试一试127.0.0.1:8000/regist
6、vim blog/views.py
增加这些
from django.http import HttpResponseRedirect
def login(req):
23 if req.method == "POST":
24 uf = UserForm(req.POST)
25 if uf.is_valid():
26 username = uf.cleaned_data['username']
27 password = uf.cleaned_data['password']
28 users = User.objects.filter(username__exact=username,password__exact=password)
29 if users:
30 return HttpResponseRedirect('/index/')
31 else:
32 return HttpResponseRedirect('/login/')
33 else:
34 uf = UserForm()
35 return render_to_response('login.html',{'uf':uf})
36 def index(req):
37 return HttpResponse('ok')
再去试一试127.0.0.1:8000/login 会跳转到index 127.0.0.1:8000/index 直接访问index会返回OK
6、vim blog/views.py 顺便cp regist.html login.html
def index(req):
username = req.COOKIES.get('username','') 用cook获取用户名，在网页界面还可以去查找，在freference-->privacy-->选use custome for settings history -->show cookies就可以看到了
return render_to_response('index.html', {'username':username})
def logout(req):
response = HttpResponse('logout')
response.delete_cookie('username') cookie 的删除方式
return response
7 、 vim blog/templates/index.html
<div>
<h1>welcome {{username}}</h1>
<a href='/logout/'>logout</a>
</div>
这样index下就会有个logout可以选择退出
