class Marten::Middleware::ContentSecurityPolicy

Overview

Sets the Content-Security-Policy header in the response if it wasn't already set.

This middleware guarantees the presence of the Content-Security-Policy header in the response's headers. This header provides clients with the ability to limit the allowed sources of different types of content.

By default, the middleware will include a Content-Security-Policy header that corresponds to the policy defined in the content_security_policy settings. However, if a Marten::HTTP::ContentSecurityPolicy object is explicitly assigned to the request object, it will take precedence over the default policy and be used instead.

Defined in:

marten/middleware/content_security_policy.cr

Instance Method Detail

def call(request : Marten::HTTP::Request, get_response : Proc(Marten::HTTP::Response)) : Marten::HTTP::Response #
Description copied from class Marten::Middleware

Calls the middleware for a given HTTP request and returns a HTTP response.

This method must be implemented by subclasses: it takes a request argument (the current HTTP request) and a get_response proc that allows to get the final response. This proc might actually call the next middleware in the chain of configured middlewares, or the final matched handler. That way, the current middleware have the ability to intercept any incoming request and the associated response, and to modify them if applicable.
