###前提・実現したいこと
UnityでC#を用いたクライアントサイドのアプリからユーザー情報を入力しJSONでrクエスト絵お送信し、サーバーサイドのRailsAPIに送られてきたリクエストをデコードして保存し、Deviseでユーザー登録する機能を作成しています。
クライアント側で送信されたリクエストを受け取った時、送られてきたJSONのリクエストがデコードされず、弾かれているという状態だと推測しています。
Rackやconfig/initializer.rbなどの知識がなく、特にサーバーサイドではどの部分でデコードを定義しているのか推測できません。
クライアントから送られててきたリクエストをサーバー側でparamsに変換し、ユーザーの認証が成功してパラメーターが保存できる形を目指しております。
