[Django]-Django – how to access request body in a decorator?

You can define the decorator inside the custom_cache_page, like:

from functools import wraps

def custom_cache_page(timeout, *, cache=None, key_prefix=None):
    callto = decorator_from_middleware_with_args(CacheMiddleware)(
        page_timeout=85,
        cache_alias=cache,
        key_prefix=key_prefix,
    )
    def decorator(view):
        @wraps(view)
        def f(request, *args, **kwargs):
            print(request)
            return callto(view)(request, *args, **kwargs)
        return f
    return decorator
