This method is used to send a 400 ("Bad Request") response back down to the client, indicating that the request is invalid. This usually means that the request contained invalid parameters or headers, or that it tried to do something not supported by your app logic.
Like the other built-in custom response modules, the behavior of this method is customizable.
By default, it works as follows:
dataas JSON. If no
datais provided, a default response body will be sent (the string
if ( req.param('amount') > 123 ) return res.badRequest( 'Transaction limit exceeded. Please try again with an amount less than $123.' ); }
- This method is terminal, meaning it is generally the last line of code your app should run for a given request (hence the advisory usage of
returnthroughout these docs).
res.badRequest()(like other userland response methods) can be overridden or modified. It runs the response method defined in
api/responses/badRequest.js. If a
badRequest.jsresponse method does not exist in your app, Sails will implicitly use the default behavior.
- This method is called automatically by the Blueprint Actions when bad parameters are sent with a request.
