Linux下开发python django程序(Session读写)

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!!')
