BubbleWrap::HTTP.getのブロック内にyield実行させようとしたらエラー

Posted at

これと同じ問題だった。

bubble-wrap-httpのソースを読むと、callで呼ぶようになってるのでたぶんこれが原因。
https://github.com/rubymotion/BubbleWrap-HTTP/blob/master/motion/http/query.rb#L397

じゃあどうするか。
取り敢えずは以下のようにデリゲート用メソッドを加える形で解決しました。

class SpotSearch
  attr_accessor :delegate

  def initialize(attributes = {})
  end

  def find(keyword)
    # ... urlとかpayloadとか色々指定済みということで ...
    BW::HTTP.get(url, payload: payload) do |response|
      @delegate.call(response) if @delegate
    end
  end
end

search = SpotSearch.new
search.delegate = Proc.new {|response|
  puts response # -> ちゃんと動く
}
search.find('銀座 カフェ')

最終的にはもっとスマートにメソッドを登録、呼び出しができればいいのだと思う。
色々ハマったけど、おかげでブロックとかProcとか少し理解できました。
