Linux下开发python django程序(Cookie读写)

1.设置cookie信息(登陆成功后设置登陆用户名，有效期1小时)

def login(req):
    if req.method == 'POST':
        loginform = LoginForm(req.POST)
        if loginform.is_valid():
            print loginform.cleaned_data
            username = loginform.cleaned_data["username"]
            password = loginform.cleaned_data["userpwd"]
            users=RegisterUser.objects.filter(username =username , password =password)
            print users
            if users:
                           response= HttpResponseRedirect('/app1/index1/')
                response.set_cookie('username',username,3600)
                return response
            else:
               return HttpResponseRedirect('/app1/login/')

    else:
        loginform = LoginForm()

    return render_to_response('login.html',{'loginform':loginform})    

templates中对应的模板页面

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title></title>
</head>
<body>
{% if islogin %}
  <li>登录用户:{{loginusername}} <a href="/app1/loginout/">Logout</a></li>

{%else %}
  <li><a href="/app1/login/">Login</a></li>
{%endif%}
<div>
{% for book in books  %}
  <h1>书籍:{{book}}<br></h1>
  {% for au in book.author.all %}
    作者: {{au}}
    <br/>
  {%endfor%}
{% endfor%}
</div>
</body>
</html>

2.检查获取当前cookie信息(判断是否登陆)

def index1(req):
     loginusername = req.COOKIES.get('username','')
     print loginusername
     islogin=False
     if loginusername:
        islogin=True
     else:
        islogin=False

     aus = Author.objects.all()
     books = Book.objects.all()
     t= loader.get_template('index1.html')
     c=Context({'aus':aus,'books':books,'islogin':islogin,'loginusername':loginusername})
     return HttpResponse(t.render(c))

3.删除cookie信息

def loginout(req):
    response =HttpResponseRedirect('/app1/index1/')
    response.delete_cookie('username')
    return response
