Django Localhost CORS无法正常工作

我有一个本地Django设置如下

Django Rest Framework:localhost:8000

AngularJS frontend:local apache running on http://localservername

我安装了django-cors-headers,在我的settings.py,我设置了我的

CORS_ORIGIN_WHITELIST = (
    'http://localhost',
    'localservername',
    'http://localservername',
    '127.0.0.1'
)


MIDDLEWARE_CLASSES = (
'django.contrib.sessions.middleware.SessionMiddleware',
'corsheaders.middleware.CorsMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

但是,No 'Access-Control-Allow-Origin' header is present on the requested resource.每当我点击任何API时,我都会收到错误Rest Framework.如果我设置了CORS_ORIGIN_ALLOW_ALL = True,那么API的工作正常,但对我的服务器端数据来说是非常不安全的.

我需要更改什么来解决这个问题？
