1.配置settings文件
（1）注意：需要先创建app(djnago-admin startapp app名称)
（2）配置模板文件
'DIRS': [os.path.join(BASE_DIR, 'templates')],
（3）配置静态文件(这里我由于存放清洗好的需要进行可视化的文件)
STATIC_URL = 'static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static')
]
2.配置主路由（path后面的为“”表示默认，假设有多个会直接跳转到默认的）
urlpatterns = [
path('', include(('pro.urls', 'pro'), namespace='pro')),
]
3.app中的views文件
