django 1.11中使用response.set_cookie()

先贴出我要做网页的代码:(views.py)

from django.shortcuts import render,render_to_response
from django.http import HttpResponse
from django.http import request,HttpResponseRedirect
from django.template.loader import get_template
from django.template import RequestContext
from form import models,forms

# Create your views here.
def index(request,pid = None,del_pass=None):
    if 'username' in request.COOKIES and 'usercolor' in request.COOKIES:
        username = request.COOKIES['username']
        usercolor = request.COOKIES['usercolor']
    template = get_template('index.html')
    html = template.render(locals())
    return HttpResponse(html)

def login(request):
    message = '请登录!'
    if request.method == 'POST':
        login_form = forms.LoginForm(request.POST)
        if login_form.is_valid():
            username = request.POST['user_name']
            usercolor = request.POST['user_color']
            message = '登录成功!'
        else:
            message = '请检查输入的字段内容'
    else:
        login_form = forms.LoginForm()
    template = get_template('login.html')
    html = template.render(context=locals(),request = request)
    response = HttpResponse(html)
    try:
        if username:response.set_cookie('username',username.encode('utf-8'))
        if usercolor:response.set_cookie('usercolor',usercolor.encode('utf-8'))
    except:
        pass
    return response

def logout(request):
    response = HttpResponseRedirect('/')
    response.delete_cookie('username')
    return response

本人是借助<<python新手使用Django框架的16堂课>>的内容,发现了set_cookie()的编码问题.

本人也是初学Django,在这只是先贴出解决方案,并不能解释原因.

若是按照书上的写法,直接写ifusername:response.set_cookie('username',username)

则会有如下报错

----------------------------------------

 

 解决方法是编码:if username:response.set_cookie('username',username.encode('utf-8'))

django2.0中可不加.encode('utf-8')

希望能给也卡在这里的朋友一点帮助,如果确实帮助到你的话,希望给我个赞哈.hhhhhh..
