Linux下开发python django程序(Cookie读写)

Posted 2020-08-10

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})    

 

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
