pg.ring.json — com.github.igrishaev/pg2-core 0.1.19

Like ring.middleware.json but faster because uses internal JSON engine instead of Cheshire.

CT_JSON clj

json-request? clj

(json-request? request)

True if it was a request with JSON payload.

JSON_ERR clj

RESP-JSON-MALFORMED clj

wrap-json clj

(wrap-json handler)

(wrap-json handler options)

Two in one: wrap a handler with wrap-json-request and wrap-json-response. All the optional parameters are supported.

wrap-json-request clj

(wrap-json-request handler)

(wrap-json-request handler
                   {:keys [slot object-mapper malformed-response]
                    :or {slot :json malformed-response RESP-JSON-MALFORMED}})

If it was a JSON request, parse the body and assoc the data into a dedicated field. We do not overwrite the :body field because it's still might be needed to calculate a checksum, for example.

Suports the following options:

• :slot -- the field where the parsed JSON data gets associated;
• :malformed-response -- a response map which gets returned when we could not parse the payload. Default is 400 with a plain text error message;
• :object-mapper -- an instance of com.fasterxml.jackson.databind.ObjectMapper for custom JSON encoding and decoding.

wrap-json-response clj

(wrap-json-response handler)

(wrap-json-response handler {:keys [object-mapper]})

If the :body of the response is a collection, JSON-encode it and add a corresponding HTTP header.

Supports the following options:

• :object-mapper -- an instance of com.fasterxml.jackson.databind.ObjectMapper for custom JSON encoding and decoding.
