登录CentOS7系统，打开终端进入python虚拟环境，创建Django工程djbody，在工程中创建app，命令如下： workon djandotestdjango-admin startproject djbodycd djbody/python manage.py startapp book tree
打开工程的settings.py文件，将本机ip添加allowed_hosts，添加app到installed_apps，注释掉中间件'django.middleware.csrf.CsrfViewMiddleware',cd djbodyvi settings.py修改后部分setting.py文件如下：ALLOWED_HOSTS = ['192.168.128.25']# Application definitionINSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'book.apps.BookConfig',]MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware',# 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware',]
在工程的urls.py添加到app的路由vi urls.pyurls.py文件如下：from django.conf.urls import url,includefrom django.contrib import adminurlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^book/', include('book.urls')),]
在app的创建urls.py文件，定义到视图函数index的路由cd ../bookvi urls.pyurls.py文件如下：from django.conf.urls import urlfrom . import viewsurlpatterns = [ url(r'^index/', views.index),]
在app的views.py文件，定义视图函数index,获取http请求体的内容，这里请求体是json字符串vi views.pyviews.py文件如下：from django.shortcuts import renderfrom django.http import JsonResponseimport json# Create your views here.def index(request): jsonstr = request.body data = json.loads(jsonstr) print (data['var1']) print (data['var2']) return JsonResponse({'msg':'recieved msg '})这里使用JsonResponse返回数据也是json字符串格式
运行django服务器cd ..python manage.py runserver 192.168.128.25:8000
在局域网任意一台电脑使用POSTMAN发送POST请求，请求体是json格式，具体如下图，注意json字符串里的字符串一定是双引号，点击Send发送，收到返回的json字符串
在控制台打印出发送的json内容的value值helloworld成功获取到json数据了
