module Roda::RodaPlugins::JsonParser

  1. lib/roda/plugins/json_parser.rb

The json_parser plugin parses request bodies in json format if the request's content type specifies json. This is mostly designed for use with JSON API sites.

This only parses the request body as JSON if the Content-Type header for the request includes “json”.

configure (app, opts=OPTS)

Handle options for the json_parser plugin:

:error_handler

A proc to call if an exception is raised when parsing a JSON request body. The proc is called with the request object, and should probably call halt on the request or raise an exception.

:parser

The parser to use for parsing incoming json. Should be an object that responds to +call(str)+ and returns the parsed data. The default is to call JSON.parse.

:include_request

If true, the parser will be called with the request object as the second argument, so the parser needs to respond to +call(str, request)+.
