没有使用Django Rest Framework API的'Access-Control-Allow-Origin' [英] No 'Access-Control-Allow-Origin' using django rest framework api

问题描述

pip3 install django-cors-headers
Requirement already satisfied: django-cors-headers in /usr/local/lib/python3.6/site-packages
You are using pip version 9.0.1, however version 9.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我运行了以下命令:

然后我将其分别设置为INSTALLED_APPS，如下所示:

I then set it in my INSTALLED_APPS respectivelikey like this:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'corsheaders'
]

然后我在这样的中间件中使用它，

I then use it in middleware like this,

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware'
    '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',
]

我收到以下错误:

ModuleNotFoundError: No module named 'corsheaders.middleware.CorsMiddlewaredjango'; 'corsheaders.middleware' is not a package

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/django/utils/autoreload.py", line 225, in wrapper
    fn(*args, **kwargs)
  File "/usr/local/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 140, in inner_run
    handler = self.get_handler(*args, **options)
  File "/usr/local/lib/python3.6/site-packages/django/contrib/staticfiles/management/commands/runserver.py", line 27, in get_handler
    handler = super().get_handler(*args, **options)
  File "/usr/local/lib/python3.6/site-packages/django/core/management/commands/runserver.py", line 65, in get_handler
    return get_internal_wsgi_application()
  File "/usr/local/lib/python3.6/site-packages/django/core/servers/basehttp.py", line 49, in get_internal_wsgi_application
    ) from err
django.core.exceptions.ImproperlyConfigured: WSGI application 'instawork.wsgi.application' could not be loaded; Error importing module.

我遵循严格的说明，我目前也在使用最新的django框架.

I've followed strict instructions, I'm currently using latest django framework too.

推荐答案

您错过了逗号，正确的 MIDDLEWARE 是:

You've missed comma, correct MIDDLEWARE is:

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',
    '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 INSTALLED_APPS 之前放置 CORS_ORIGIN_ALLOW_ALL = True .您还可以指定允许使用cors的主机:

Put CORS_ORIGIN_ALLOW_ALL=True before INSTALLED_APPS. You can also specify hosts allowed for cors:

CORS_ORIGIN_WHITELIST = (
    'example.com',
)
