%global _empty_manifest_terminate_build 0 Name: python-Flask-ErrorsHandler Version: 4.0.2 Release: 1 Summary: Customizable errors handler for flask application and blueprints License: MIT URL: https://github.com/cs91chris/flask_errors_handler Source0: https://mirrors.aliyun.com/pypi/web/packages/c3/ae/404fa9ee5ea0884ab1faff1ae055d2c34e73d34cab8c157ddda22ee28c1d/Flask-ErrorsHandler-4.0.2.tar.gz BuildArch: noarch Requires: python3-Flask %description |version| Set customizable default errors handler for flask app and blueprints. You can register error handler for: - api that returns JSON, default response is as API problem specification like (see https://tools.ietf.org/html/rfc7807). Instead you can use your own response implementation passed as argument to ``ErrorHandler`` class: it must be a decorator and must take 3 args, a dict response, status code and dict headers. - web that returns html page or api response if request is XHR (for compatibility with old clients) - you can register custom handlers for blueprint or the entire app This module provide also an abstract ``ErrorDispatcher`` class in order to dispatch 404 or 405 error to the correct blueprint because flask Blueprint does not own url_prefix (see https://github.com/pallets/flask/issues/1498). There are 2 concrete implementation: - ``SubdomainDispatcher``: dispatch the error to the handler associate with blueprint with certain subdomain (if 2 or more Blueprint has the same subdomain the first blueprint handler matched is used) - ``URLPrefixDispatcher``: dispatch the error to the handler associate with blueprint with certain url prefix. This will not work if 2 Blueprint are registered under the same url prefix, for example: Blueprint A registered under /prefix/blueprint, Blueprint B registered under /prefix, this dispatcher executes the handler of B in both case if B is registered after A. Moreover you can create you own dispatcher by extending ``ErrorDispatcher`` class and implementing ``dispatch`` method. Only the *last* ErrorDispatcher registered is executed. This is the best solution I have found, suggestions are welcome. Notices: 1. In order to use correctly dispatcher you must set prefix or subdomain in Blueprints constructor, see example below. 2. If you use dispatcher do not register an handler to app object because it overwrites dispatcher. 3. When using a dispatcher you should use failure handler on app to catch unhandled exceptions.
