前端代码报错,如图:

 1、因本地不支持跨域,需要安装下【允许跨域的app】

pip install django-cors-headers

 2、回到Django项目中进入setting.py

INSTALLED_APPS:

# 我们创建了哪些子项目要在这里添加,不然如数据库的类不会帮创建
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'sky',
    'user',
    'corsheaders' # 允许跨域的
]

MIDDLEWARE:

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'corsheaders.middleware.CorsMiddleware'  # 允许跨域的中间件,需要安装:pip install django-cors-headers
    # 'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    # 'sky.middle_wares.TestMiddleWare',  # 以下是自定义中间件
    'user.middle_wares.PutMethodMiddleware',
    'user.middle_wares.SessionMiddleware',  # 报错处理
    'user.middle_wares.ExceptionMiddleware'  # 验证token
]

 配上以下2个参数:

CORS_ORIGIN_ALLOW_ALL = True # 加上这个允许所有跨域

CORS_ALLOW_HEADERS = '*'
