def write_error(self, status_code: int, **kwargs: Any)

Question

def write_error(self, status_code: int, **kwargs: Any)

-> None:
"""Override to implement custom error pages.

``write_error`` may call `write`, `render`, `set_header`, etc
to produce output as usual.

If this error was caused by an uncaught exception (including
HTTPError), an ``exc_info`` triple will be available as
``kwargs["exc_info"]``. Note that this exception may not be
the "current" exception for purposes of methods like
``sys.exc_info()`` or ``traceback.format_exc``.
"""
if self.settings.get("serve_traceback") and "exc_info" in kwargs:
# in debug mode, try to send a traceback
self.set_header("Content-Type", "text/plain")
for line in traceback.format_exception(*kwargs["exc_info"]):
self.write(line)
self.finish()
else:
self.finish(
"<html><title>%(code)d: %(message)s</title>"
"<body>%(code)d: %(message)s</body></html>"
% {"code": status_code, "message": self._reason}
)
Это?
