django 接口编写的配置

一.修改settings文件

ALLOWED_HOSTS = ['*']

INSTALLED_APPS = [ 'corsheaders' ]    #加入该app

安装django-cors-headers：

pip install django-cors-headers

#注释掉跨域的中间件CsrfViewMiddleware，SessionMiddleware要在AuthenticationMiddleware前面，CorsMiddleware要在CommonMiddleware前面

MIDDLEWARE = [

'django.middleware.security.SecurityMiddleware',

'corsheaders.middleware.CorsMiddleware',

'django.middleware.common.CommonMiddleware',

#'django.middleware.csrf.CsrfViewMiddleware',

'django.contrib.sessions.middleware.SessionMiddleware',

'django.contrib.auth.middleware.AuthenticationMiddleware',

'django.contrib.messages.middleware.MessageMiddleware',

'django.middleware.clickjacking.XFrameOptionsMiddleware', ]

加入跨域配置：

CORS_ALLOW_CREDENTIALS = True

CORS_ORIGIN_ALLOW_ALL = True

CORS_ORIGIN_WHITELIST = ( '*' )

CORS_ALLOW_METHODS = ( 'DELETE', 'GET', 'OPTIONS', 'PATCH', 'POST', 'PUT', 'VIEW', )

CORS_ALLOW_HEADERS = ( 'XMLHttpRequest', 'X_FILENAME', 'accept-encoding', 'authorization', 'content-type', 'dnt', 'origin', 'user-agent', 'x-csrftoken', 'x-requested-with', 'Pragma', )

运行项目时，输入命令#Python manage.py runserver 192.168.1.111:8000，在本机的浏览器中输入http://192.168.1.111:8000
