django後端跨越訪問問題

先寫個博客,後面我再更新手冊

1.問題：頁面訪問時報錯

Forbidden (CSRF cookie not set.): xxx

解決方法：

修改settings.py文件，註釋掉

django.middleware.csrf.CsrfViewMiddleware'

 

2.問題：ajax跨域請求時報錯

解決方法：

1、安裝django-cors-headers

pip install django-cors-headers

 

2、配置settings.py文件

a.在INSTALLED_APPS裏添加“corsheaders”
 

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

 

b.在MIDDLEWARE_CLASSES添加配置：

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',
    'django.middleware.common.CommonMiddleware',
]

c.在sitting.py底部添加

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 = (
    'accept',
    'accept-encoding',
    'authorization',
    'content-type',
    'dnt',
    'origin',
    'user-agent',
    'x-csrftoken',
    'x-requested-with',
)

3.油猴原生腳本可以再開頭加入這麼一句話:

var s = document.createElement('meta');
s.setAttribute('http-equiv', 'Access-Control-Allow-Origin');
s.setAttribute('content', '*');
document.head.appendChild(s);

4.等同於在網頁上加上這麼一句;

<meta http-equiv="Access-Control-Allow-Origin" content="*" />
