python-3.x - 如何更改烧瓶限制器错误页面？

Question

我在某些地方使用烧瓶限制器库以避免过度拥挤。当请求太多时，我在下面抛出的页面会转动。我想更改此页面。返回此页面的代码如下。

"""
errors and exceptions
"""

from distutils.version import LooseVersion
from pkg_resources import get_distribution
from six import text_type
from werkzeug import exceptions

werkzeug_exception = None
werkzeug_version = get_distribution("werkzeug").version
if LooseVersion(werkzeug_version) < LooseVersion("0.9"):  # pragma: no cover
    # sorry, for touching your internals :).
    import werkzeug._internal
    werkzeug._internal.HTTP_STATUS_CODES[429] = 'Too Many Requests'
    werkzeug_exception = exceptions.HTTPException
else:
    # Werkzeug 0.9 and up have an existing exception for 429
    werkzeug_exception = exceptions.TooManyRequests


class RateLimitExceeded(werkzeug_exception):
    """
    exception raised when a rate limit is hit.
    The exception results in ``abort(429)`` being called.
    """
    code = 429
    limit = None

    def __init__(self, limit):
        self.limit = limit
        if limit.error_message:
            description = limit.error_message if not callable(
                limit.error_message
            ) else limit.error_message()
        else:
            description = text_type(limit.limit)
        super(RateLimitExceeded, self).__init__(description=description)
