vue+django跨域问题

解决办法：

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',
    'yshop.middleware.AuthorizeMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

# CSRF_COOKIE_HTTPONLY = True

CORS_ALLOWED_ORIGINS = [
    'http://127.0.0.1:8080',  # 允许跨域请求的源
]

CORS_ORIGIN_WHITELIST = [
    'http://127.0.0.1:8080',
]

CORS_ALLOW_METHODS = [
    'DELETE',
    'GET',
    'OPTIONS',
    'PATCH',
    'POST',
    'PUT',
    'VIEW',
]

CORS_ALLOW_HEADERS = [
    'username',  # 允许的请求头
    'Authorization',
    '*',
    'dnt',
    'source',
    'origin',
    'Pragma',
    'accept',
    'user-agent',
    'x-csrftoken',
    'X_FILENAME',
    'content-type',
    'authorization',
    'authentication',
    'XMLHttpRequest',
    'accept-encoding',
    "x-requested-with",
]

REST_FRAMEWORK = {

    'DEFAULT_AUTHENTICATION_CLASSES': (

        'rest_framework.authentication.TokenAuthentication',

    )

}
# 支持跨域配置开始
CORS_ORIGIN_ALLOW_ALL = True
CORS_ALLOW_CREDENTIALS = True




最重要的一点：
中间件的顺序：

'corsheaders.middleware.CorsMiddleware', 必须放第一个！！！
