1.在pycharm创建Djongo项目。

2.在项目内，创建一个APP。

3.在新建APP内创建urls.py。

4.设置跨域：

下包

pip install django-cors-headers

下面的操作在setting里

添加到appps里

INSTALLED_APPS = [

    ...

    ‘corsheaders‘，

    ...

 ]

注释掉csrf并添加‘corsheaders.middleware.CorsMiddleware‘

   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‘,

    ‘corsheaders.middleware.CorsMiddleware‘,

]

添加跨域配置

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‘,
)
