1.登陆设置session信息
def loginsession(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:
req.session['username']=username
return HttpResponseRedirect('/app1/indexsession/')
else:
return HttpResponseRedirect('/app1/login/') else:
loginform = LoginForm() return render_to_response('login.html',{'loginform':loginform})
template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:{{sessionloginname}} <a href="/app1/loginoutsession/">Logout</a></li> {%else %}
<li><a href="/app1/loginsession/">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.获取session中的用户信息
def indexsession(req):
sessionloginname = req.session.get('username','') print 'sessionloginname:'+sessionloginname islogin=False
if sessionloginname :
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,'sessionloginname':sessionloginname})
return HttpResponse(t.render(c))
3.删除session中信息
def loginoutsession(req):
del req.session['username']
return HttpResponse('loginout ok!!')
