【Sinatra】POSTメソッドでJSONを受け取りたい

Posted at

Railsのノリでparamsを見ても空のHashになってる.
GETメソッドはparamsでも大丈夫なんだけど…

とりあえずrequest.bodyを読み込んでJSONにパースすることで解決.

app.rb
# coding: utf-8

require 'sinatra'
require 'json'

post '/', provides: :json do
  params = JSON.parse request.body.read

end

# 後略

実際にPOSTしてみる.

console
$ curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"hoge":"ほげほげ","fuga":"ふがふが","piyo":"ぴよぴよ"}' http://localhost:4567/

たぶんparams[:hoge]とかparams[:fuga]で参照できるはず.

Rack::Request#paramsから辿って行くとRack::Request#POSTに以下の記述が.

This method support both application/x-www-form-urlencoded and multipart/form-data.

application/jsonには対応してないのね….
