Django-服务器端对象-跨域请求

1. 在接口函数中配置

    from django.http import HttpResponse,response,JsonResponse
    def login(request):
        todo_list = [
            {"id": "1", "content": "吃饭"},
            {"id": "2", "content": "吃饭"},
        ]
        response = JsonResponse(todo_list, safe=False)
        response["Access-Control-Allow-Origin"] = "*"
        response["Access-Control-Allow-Methods"] = "POST, GET, OPTIONS"
        response["Access-Control-Max-Age"] = "1000"
        response["Access-Control-Allow-Headers"] = "*"
        return response
   

2. 安装CORS

    pip install django-cors-headers
   

3. 添加app

    INSTALLED_APPS = (
        ...
        'corsheaders',
        ...
    )
   

4. 添加中间件

    MIDDLEWARE = [  # Or MIDDLEWARE_CLASSES on Django < 1.10
        ...
        'corsheaders.middleware.CorsMiddleware',
        'django.middleware.common.CommonMiddleware',
        ...
    ]
   

5. 配置允许跨站访问本站

   1. 配置允许跨站访问本站的地址

       CORS_ORIGIN_ALLOW_ALL = False
       CORS_ORIGIN_WHITELIST = (
             'localhost:63343',
       )
       
       # 默认值是全部:
       CORS_ORIGIN_WHITELIST = ()  # 或者定义允许的匹配路径正则表达式.
       
       CORS_ORIGIN_REGEX_WHITELIST = ('^(https?://)?(\w+.)?>google.com$', )   # 默认值:
       
       CORS_ORIGIN_REGEX_WHITELIST = ()
      

   2. 设置允许访问的方法

       CORS_ALLOW_METHODS = (
       'GET',
       'POST',
       'PUT',
       'PATCH',
       'DELETE',
       'OPTIONS'
       )
      

   3. 设置允许的header：

       默认值:
       
       CORS_ALLOW_HEADERS = (
       'x-requested-with',
       'content-type',
       'accept',
       'origin',
       'authorization',
       'x-csrftoken'
       )
