Django-cookie与session操作

添加cookie：

    def login(req):
        if req.method=="POST":
            uf = UserInfoForm(req.POST)
            if uf.is_valid():
                username = uf.cleaned_data["username"]
                password = uf.cleaned_data["password"]
                print username,password
                users = UserInfo.objects.filter(username=username,password=password)
                if users:
                    response = HttpResponseRedirect("/index/")
                    response.set_cookie("username",username,3600)
                    return response
                else:
                    return HttpResponseRedirect("/login")
                # return HttpResponseRedirect()
        else:
            uf = UserInfoForm()
        return render_to_response("login.html",{"uf":uf})

获得cookie:

def index(req):
        username = req.COOKIES.get("username","")
        return render_to_response("index.html",{"username":username})

删除cookie:

Response.delete_cookie("username")

添加session：

def sesion(req):
    if req.method == "POST":
       uf = UserInfoForm(req.POST)
       if uf.is_valid():
          username = uf.cleaned_data["username"]
          req.session["username"] = username
          return HttpResponseRedirect("/index/")
       else:
          uf = UserInfoForm()
       return render_to_response("LoadFile.html",{"uf":uf})

获取session：

def index(req):
    username = req.session.get("username","")
    return render_to_response("index.html",{"username":username})

删除session：

    del req.session['username']
