This article introduces cookie and session operations in Django through sample code. Friends who need it can refer to it

Add cookies:

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})

Get cookie:

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

Delete cookie:

  Response.delete_cookie("username")

Add 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})

Get session:

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

Delete session:
