blueprint.handler.default — exoscale/blueprint-handler 0.2.54

Implementation of the default interceptors. See blueprint.handler for reasoning

add-original-request clj

Store original request

final clj

An interceptor which extracts the response key to conform to ring behavior

get-root-paths clj

(get-root-paths prefix)

handler clj

An interceptor which defers to a provided handler

logger clj

A generic request/response/error logger that logs request and elapsed time. Rethrows any error

normalize clj

Request normalizer, merges params coming from the body, path, or query string and produces a single input map. Assoc's the handler name to allow command spec evaluation

not-found clj

Quit the chain when the handler is not found.

original-request clj

Retrieve original request from a context

payload-size clj multimethod

prepare-payload clj

(prepare-payload paths context)

A helper for handler which pulls appropriate keys from the context to prepare the request payload.

By default (for a nil path spec), the value stored at :request in the context is extracted.

For a value of :blueprint.handler/raw, the context itself is passed down.

If a collection of keys is given, it is looked up in the context.

The last possible specification allows fetching keys in various places in the context to build the resulting request payload. In this case the specification is given as a map of path to path, with the option to ask for merging of the result:

{[:request]                      :blueprint.handler/merge
 [:subsystem :some/generated-id] [:important-id]}

In this map paths are always expressed as collection of keys. In the target specification, a value of :blueprint.handler/merge will merge the result of the lookup onto the request payload, rather than associng it.

resettable-inputstream clj

(resettable-inputstream payload-opts ctx)

route clj

Routing interceptor, needs router from blueprint.router/generate-router

service-desc clj

Service descriptor interceptor, happens after routing on :not-found errors

transform clj

Validates and coerces normalized input as per spec if possible or throws

wrap-input-stream clj

assert the body request is an input stream instance that is resettable, which means supports reset operation.

wrap-response-body clj

Wrap response from handler in a valid ring response map if none is found
