django入门到精通②使用django搭建简单的ip地址获取所在国家和城市api服务器

1.基本环境配置

windows 10
安装python3.7.2


安装虚拟环境(避免环境之间相互污染)
C:\Users\ws>pip install virtualenv

pip install virtualenvwrapper-win
# 创建基于python3.7的虚拟环境
mkvirtualenv.bat python37_django2

# 进入虚拟环境
workon python37_django2

# 安装基本的依赖插件

pip install django==2.1.2
pip install requests
pip install requests geoip2

# 进入d:/python 这个源码目录，在指定位置创建项目

django-admin startproject simple_ip_server
cd simple_ip_server
python manage.py startapp ipserver

2.设置IDE工具开发环境
用pycharm打开项目

3.配置django

配置基本的环境，添加app

设置 语言、时区 环境
LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'

编写api的视图

ipserver/views.py

# coding:utf-8

from django.http import HttpResponse,JsonResponse
from django.views import View
import geoip2.database


class IpServer(View):

    def get(self, request):

        reader = geoip2.database.Reader(r'D:\python\simple_ip_server\ipserver\GeoLite2-City.mmdb')
        ipaddress = request.GET.get('ipaddress', '')

        if not ipaddress:
            return JsonResponse({'errorcode':-1, 'errmsg': 'ip地址不能为空'})

        response = reader.city(ipaddress)

        country = response.country.iso_code
        cityname = response.city.name

        data = {'country':country, 'city':cityname}

        return JsonResponse({'errorcod':0, 'errmsg': 'success', 'data': data})

# 设置urls 路由信息

ipserver/urls.py

# _*_ coding:utf-8 _*_
# __author__ == 'jack'
# __date__ == '2020-12-30 10:41 AM'


from django.urls import path
from .views import IpServer

urlpatterns = [
    path('ip/', IpServer.as_view())
]

在总路由 simple_ip_server/urls.py 中引入

from django.contrib import admin
from django.urls import path, include
from ipserver import urls as ipserver_urls

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include(ipserver_urls))
]

# 启动服务器
(python37_django2) D:\python\simple_ip_server>python manage.py runserver

# 测试
