1.准备阶段
滑动验证码我们可以直接用GEETEST的滑动验证码。
打开网址：https://www.geetest.com/ ，找到技术文档中的行为验证，打开部署文档，点击Python，下载ZIP包。
ZIP包下载地址：https://github.com/GeeTeam/gt3-python-sdk/archive/master.zip
解压，找到django_demo，为了方便复制粘贴代码，可以用编辑器打开项目。
2.实施
自己先写一个简单的登录，然后将django_demo中的关键代码复制到我们自己的项目中。过程省去，我直接贴代码。

2.3.urls.py（部署路径）

BBS URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

2.5.settings.py
settings.py需要加一些东西。首先创建一个数据库，用于存储各类表。创建好之后，需要连接pycharm。
DATABASES =
{
'
default
'
: {
'
ENGINE
'
:
'
django.db.backends.mysql
'
,
'
NAME
'
:
'
bbs
'
,
'
HOST
'
:
'
127.0.0.1
'
,
'
PORT
'
:
'
3306
'
,
'
USER
'
:
'
root
'
,
'
PASSWORD
'
:
'
000000
'
,
}
}
同时在项目下的app目录中的__init__.py中加上两行代码，告诉pychram我用了mysql。
import
pymysql
pymysql.install_as_MySQLdb()
在settings.py的最下方加上:
STATICFILES_DIRS =
[
os.path.join(BASE_DIR,
"
static
"
)
]
2.6.生成用户
终端执行两行代码：
python manage.py makemigrations
python manage.py migrate
在auth_user表中添加一个用户，超级用户和普通用户都可以。
python manage.py createsuperuser
