omn ​​iauthとomniauth-mapmyfitness-oauth2を使用して、MapMyFitness ユーザーが自分のサイトにサインインできるようにしています。

最近、サインインを何度か試みた結果、以下のエラーが発生しました。Rails アプリのコードでエラーが発生しているようには見えません。完全に ruby​​、gem、または MapMyFitness API 内にあるようです。

これをデバッグする方法に関する指示/情報/提案は大歓迎です。このような問題はこれまで経験したことがないので、大きな学習の機会です。

/usr/lib/ruby/1.9.1/net/http.rbファイルを調べたところ、1435 行目で右への参照が見つかりました.strip。

def initialize_http_header(initheader)
  @header = {}
  return unless initheader
  initheader.each do |key, value|
    warn "net/http: warning: duplicated HTTP header: #{key}" if key?(key) and $VERBOSE
    @header[key.downcase] = [value.strip]
  end
end

しかし、その情報をどうしたらよいかわかりません。

omn​​iauth-mapmyfitness-oauth2ENV['MMF_API_KEY']には、ライブラリが機能するために定義されている奇妙な要件があります。（とにかく、私には奇妙です。なぜこのように設定されたのかについてもっと知りたいです。）

これは、ストラテジ ファイルの 13 行目でその環境変数を使用しているためです。

最近サーバーを移行しましたが、この環境変数を持ってくるのを忘れていました。この回答に基づいて/etc/profile.d/mapmyfitness.sh、システム全体で利用できるようにするために、新しいファイル に 2 行を追加しました。

export MMF_API_KEY=my-key
export MMF_API_SECRET=my-secret
