This module implements a collection of `falcon.HTTPError`
specializations that can be raised to generate a 4xx or 5xx HTTP
response. All classes are available directly from the `falcon`
package namespace::
import falcon

def on_get(self, req, resp):
# ...

'TTL Out of Range',
'The message's TTL must be between 60 and 300 seconds, inclusive.'

400 Bad Request.
The server cannot or will not process the request due to something
that is perceived to be a client error (e.g., malformed request
syntax, invalid request message framing, or deceptive request
routing).
(See also: RFC 7231, Section 6.5.1)
Keyword Args:
title (str): Error title (default '400 Bad Request').
description (str): Human-friendly description of the error, along with
a helpful suggestion or two.
headers (dict or list): A ``dict`` of header names and values
to set, or a ``list`` of (*name*, *value*) tuples. Both *name* and
*value* must be of type ``str`` or ``StringType``, and only
character values 0x00 through 0xFF may be used on platforms that
use wide characters.
Note:
The Content-Type header, if present, will be overridden. If
you wish to return custom error messages, you can create
your own HTTP error class, and install an error handler
to convert it into an appropriate HTTP response for the
client
Note:
Falcon can process a list of ``tuple`` slightly faster
than a ``dict``.
href (str): A URL someone can visit to find out more information
(default ``None``). Unicode characters are percent-encoded.
href_text (str): If href is given, use this as the friendly
title/description for the link (default 'API documentation
for this error').
code (int): An internal code that customers can reference in their
support request or to help them when searching for knowledge
base articles related to this error (default ``None``).

401 Unauthorized.
The request has not been applied because it lacks valid
authentication credentials for the target resource.
The server generating a 401 response MUST send a WWW-Authenticate
header field containing at least one challenge applicable to the
target resource.
If the request included authentication credentials, then the 401
response indicates that authorization has been refused for those
credentials. The user agent MAY repeat the request with a new or
replaced Authorization header field. If the 401 response contains
the same challenge as the prior response, and the user agent has
already attempted authentication at least once, then the user agent
SHOULD present the enclosed representation to the user, since it
usually contains relevant diagnostic information.
(See also: RFC 7235, Section 3.1)
Keyword Args:
title (str): Error title (default '401 Unauthorized').
description (str): Human-friendly description of the error, along with
a helpful suggestion or two.
challenges (iterable of str): One or more authentication
challenges to use as the value of the WWW-Authenticate header in
the response.
(See also: RFC 7235, Section 2.1)
headers (dict or list): A ``dict`` of header names and values
to set, or a ``list`` of (*name*, *value*) tuples. Both *name* and
*value* must be of type ``str`` or ``StringType``, and only
character values 0x00 through 0xFF may be used on platforms that
use wide characters.
Note:
The Content-Type header, if present, will be overridden. If

HTTPForbiddena 403 Forbidden.
The server understood the request but refuses to authorize it.
A server that wishes to make public why the request has been
forbidden can describe that reason in the response payload (if any).
If authentication credentials were provided in the request, the
server considers them insufficient to grant access. The client
SHOULD NOT automatically repeat the request with the same
credentials. The client MAY repeat the request with new or different
credentials. However, a request might be forbidden for reasons
unrelated to the credentials.
An origin server that wishes to "hide" the current existence of a
forbidden target resource MAY instead respond with a status code of
404 Not Found.
(See also: RFC 7231, Section 6.5.4)
Keyword Args:

The origin server did not find a current representation for the
target resource or is not willing to disclose that one exists.
A 404 status code does not indicate whether this lack of
representation is temporary or permanent; the 410 Gone status code
is preferred over 404 if the origin server knows, presumably through
some configurable means, that the condition is likely to be
permanent.
A 404 response is cacheable by default; i.e., unless otherwise
indicated by the method definition or explicit cache controls.

The method received in the request-line is known by the origin
server but not supported by the target resource.
The origin server MUST generate an Allow header field in a 405
response containing a list of the target resource's currently
supported methods.
A 405 response is cacheable by default; i.e., unless otherwise
indicated by the method definition or explicit cache controls.

The target resource does not have a current representation that
would be acceptable to the user agent, according to the proactive
negotiation header fields received in the request, and the server
is unwilling to supply a default representation.
The server SHOULD generate a payload containing a list of available
representation characteristics and corresponding resource
identifiers from which the user or user agent can choose the one
most appropriate. A user agent MAY automatically select the most
appropriate choice from that list. However, this specification does
not define any standard for such automatic selection, as described
in RFC 7231, Section 6.4.1
(See also: RFC 7231, Section 6.5.6)
Keyword Args:

The request could not be completed due to a conflict with the
current state of the target resource. This code is used in
situations where the user might be able to resolve the conflict and
resubmit the request.
The server SHOULD generate a payload that includes enough
information for a user to recognize the source of the conflict.
Conflicts are most likely to occur in response to a PUT request. For
example, if versioning were being used and the representation being
PUT included changes to a resource that conflict with those made by
an earlier (third-party) request, the origin server might use a 409
response to indicate that it can't complete the request. In this
case, the response representation would likely contain information
useful for merging the differences based on the revision history.
(See also: RFC 7231, Section 6.5.8)
Keyword Args:

description (str): Human-friendly description of the error, along with

410 Gone.
The target resource is no longer available at the origin server and
this condition is likely to be permanent.
If the origin server does not know, or has no facility to determine,
whether or not the condition is permanent, the status code 404 Not
Found ought to be used instead.
The 410 response is primarily intended to assist the task of web
maintenance by notifying the recipient that the resource is
intentionally unavailable and that the server owners desire that
remote links to that resource be removed. Such an event is common
for limited-time, promotional services and for resources belonging
to individuals no longer associated with the origin server's site.
It is not necessary to mark all permanently unavailable resources as
"gone" or to keep the mark for any length of time -- that is left to
the discretion of the server owner.
A 410 response is cacheable by default; i.e., unless otherwise
indicated by the method definition or explicit cache controls.

This rare condition is only likely to occur when a client has
improperly converted a POST request to a GET request with long query
information, when the client has descended into a "black hole" of

that the entire operation failed.
(See also: RFC 5842, Section 7.2)
Keyword Args:
title (str): Error title (default '508 Loop Detected').
description (str): Human-friendly description of the error, along with
a helpful suggestion or two.
headers (dict or list): A ``dict`` of header names and values
to set, or a ``list`` of (*name*, *value*) tuples. Both *name* and
*value* must be of type ``str`` or ``StringType``, and only
character values 0x00 through 0xFF may be used on platforms that
use wide characters.
Note:
The Content-Type header, if present, will be overridden. If
you wish to return custom error messages, you can create
your own HTTP error class, and install an error handler
to convert it into an appropriate HTTP response for the
client
Note:
Falcon can process a list of ``tuple`` slightly faster
than a ``dict``.
href (str): A URL someone can visit to find out more information
(default ``None``). Unicode characters are percent-encoded.
href_text (str): If href is given, use this as the friendly
title/description for the link (default 'API documentation
for this error').
code (int): An internal code that customers can reference in their
support request or to help them when searching for knowledge
base articles related to this error (default ``None``).

The 511 status code indicates that the client needs to authenticate
to gain network access.
The response representation SHOULD contain a link to a resource that
allows the user to submit credentials.
Note that the 511 response SHOULD NOT contain a challenge or the
authentication interface itself, because clients would show the
interface as being associated with the originally requested URL,
which may cause confusion.
The 511 status SHOULD NOT be generated by origin servers; it is
intended for use by intercepting proxies that are interposed as a
means of controlling access to the network.
Responses with the 511 status code MUST NOT be stored by a cache.
