Django-前后端分离接口

1、发布会添加接口

2、发布会查询接口

3、嘉宾添加接口

4、嘉宾查询接口

5、嘉宾签到接口

6、配置接口路径

修改urls.py

"""loginDemo URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url
from django.contrib import admin
from django.urls import include

from loginApp import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^login/', views.login),
    url(r'^login_action/', views.login_action),
    url(r'^event_manage/', views.event_manage),
    url(r'^accounts/login',views.login),
    url(r'^search_name/',views.search_name),
    url(r'^search_phone/',views.search_phone),
    url(r'^guest_manage/',views.guest_manage),
    url(r'^sign_index/(?P<event_id>[0-9]+)/$',views.sign_index),
    url(r'^sign_index_action/(?P<event_id>[0-9]+)/$', views.sign_index_action),
    url(r'^logout/',views.logout),
    url(r'^api/', include(('loginApp.urls','loginApp'), namespace="sign")),
]

　新增loginApp/urls.py　

from django.conf.urls import url

from loginApp import views_interface

urlpatterns = [
    # guest system interface:
    # ex : /api/add_event/
    url(r'^add_event/', views_interface.add_event, name='add_event'),
    # ex : /api/add_guest/
    url(r'^add_guest/', views_interface.add_guest, name='add_guest'),
    # ex : /api/get_event_list/
    url(r'^get_event_list/', views_interface.get_event_list, name='get_event_list'),
    # ex : /api/get_guest_list/
    url(r'^get_guest_list/', views_interface.get_guest_list, name='get_guest_list'),
    # ex : /api/user_sign/
    url(r'^user_sign/', views_interface.user_sign, name='user_sign'),
]

7、启动后访问：http://127.0.0.1:8000/，用postman或者raw等接口测试工具进行测试

（1）add_event

case1：eid为空

case2：name为空

case3：limit为空

case4：address为空

case5：start_time为空

case6:start_time不是YYYY-MM-DD格式/start_time是YYYY-MM-DD格式，但不是准确的时间2021-13-21 34：21：89

case7:eid发布会id已经存在

case8：name已经存在

case9：status为空，成功创建，status=1

case10：status传参0，成功创建，status=0
