The watcher.api.hooks Module¶

class watcher.api.hooks.ContextHook[source]¶

Bases: pecan.hooks.PecanHook

Configures a request context and attaches it to the request.

The following HTTP request headers are used:

X-User:

Used for context.user.

X-User-Id:

Used for context.user_id.

X-Project-Name:

Used for context.project.

X-Project-Id:

Used for context.project_id.

X-Auth-Token:

Used for context.auth_token.

before(state)[source]¶

Override this method to create a hook that gets called after routing, but before the request gets passed to your controller.

Parameters:	state – The Pecan state object for the current request.

class watcher.api.hooks.NoExceptionTracebackHook[source]¶

Bases: pecan.hooks.PecanHook

Workaround rpc.common: deserialize_remote_exception.

deserialize_remote_exception builds rpc exception traceback into error message which is then sent to the client. Such behavior is a security concern so this hook is aimed to cut-off traceback from the error message.

after(state)[source]¶

Override this method to create a hook that gets called after the request has been handled by the controller.

Parameters:	state – The Pecan state object for the current request.
