available-charsets clj

Set of recognised charsets by the current JVM

can-encode? clj

(can-encode? {:keys [enc-type] :as encoder}
             {:keys [type sub-type] :as accepted-type})

Check whether encoder can encode to accepted-type. Accepted-type should have keys :type and :sub-type with appropriate values.

choose-charset clj

Memoized form of choose-charset*

choose-charset* clj

(choose-charset* accept-charset)

Returns an useful charset from the accept-charset string. Defaults to utf-8

default-charset-extractor clj

(default-charset-extractor request)

Default charset extractor, which returns either Accept-Charset header field or utf-8

default-formats clj

default-handle-error clj

(default-handle-error e _ _)

Default error handling function used, which rethrows the Exception

encode-msgpack clj

(encode-msgpack body)

encode-msgpack-kw clj

(encode-msgpack-kw body)

init-encoder clj

(init-encoder encoder opts)

make-encoder clj

(make-encoder encoder content-type)

(make-encoder encoder content-type binary?)

Return a encoder map suitable for [[wrap-format-response.]] f takes a string and returns an encoded string type Content-Type of the encoded string (make-encoder json/generate-string "application/json")

make-json-encoder clj

(make-json-encoder pretty options)

parse-accept-header clj

Memoized form of parse-accept-header*

parse-accept-header* clj

(parse-accept-header* accept-header)

Parse Accept headers into a sorted sequence of maps. "application/json;level=1;q=0.4" => ({:type "application" :sub-type "json" :q 0.4 :level "1"})

parse-charset-accepted clj

(parse-charset-accepted v)

Parses an accept-charset string to a list of [charset quality-score]

preferred-charset clj

(preferred-charset charsets)

Returns an acceptable choice from a list of [charset quality-score]

preferred-encoder clj

(preferred-encoder encoders req)

Return the encoder that encodes to the most preferred type. If the Accept header of the request is a String, assume it is according to Ring spec. Else assume the header is a sequence of accepted types sorted by their preference. If no accepted encoder is found, return nil. If no Accept header is found, return the first encoder.

wrap-clojure-response clj

(wrap-clojure-response handler & args)

Wrapper to serialize structures in :body to Clojure native with sane defaults. If :hf is set to true, will use print-dup for high-fidelity printing ( see here ). See wrap-format-response for more details.

wrap-format-response clj

(wrap-format-response handler & args)

Wraps a handler such that responses body to requests are formatted to the right format. If no Accept header is found, use the first encoder.

• :predicate is a predicate taking the request and response as arguments to test if serialization should be used
• :encoders a sequence of maps given by make-encoder
• :charset can be either a string representing a valid charset or a fn taking the req as argument and returning a valid charset (utf-8 is strongly suggested)
• :binary? if true :charset will be ignored and decoder will receive an InputStream
• :handle-error is a fn with a sig [exception request response]. Defaults to just rethrowing the Exception

wrap-json-response clj

(wrap-json-response handler & args)

Wrapper to serialize structures in :body to JSON with sane defaults. See wrap-format-response for more details.

wrap-msgpack-response clj

(wrap-msgpack-response handler & args)

Wrapper to serialize structures in :body to msgpack with sane defaults. See wrap-format-response for more details.

wrap-restful-response clj

(wrap-restful-response handler & args)

Wrapper that tries to do the right thing with the response :body and provide a solid basis for a RESTful API. It will serialize to JSON, YAML, Clojure, Transit or HTML-wrapped YAML depending on Accept header. See wrap-format-response for more details. Recognized formats are :json, :json-kw, :edn :yaml, :yaml-in-html, :transit-json, :transit-msgpack. Options to specific encoders can be passed in using :format-options option. If is a map from format keyword to options map.

wrap-transit-json-response clj

(wrap-transit-json-response handler & args)

Wrapper to serialize structures in :body to transit over JSON with sane defaults. See wrap-format-response for more details.

wrap-transit-msgpack-response clj

(wrap-transit-msgpack-response handler & args)

Wrapper to serialize structures in :body to transit over msgpack with sane defaults. See wrap-format-response for more details.

wrap-yaml-in-html-response clj

(wrap-yaml-in-html-response handler & args)

Wrapper to serialize structures in :body to YAML wrapped in HTML to check things out in the browser. See wrap-format-response for more details.

wrap-yaml-response clj

(wrap-yaml-response handler & args)

Wrapper to serialize structures in :body to YAML with sane defaults. See wrap-format-response for more details.
