調試獨立 Rails Controller

Question

我有一個名為“Zendesk_session_controller.rb”的 controller，作為使用 JWT 過程的第一步。但是，我想知道如何使用 binding.pry 調試它？ 我在嘗試運行該文件時收到此錯誤。

zendesk_session_controller.rb

    require 'securerandom' unless defined?(SecureRandom)
class ZendeskSessionController
  # Configuration
  ZENDESK_SHARED_SECRET = ENV['ZENDESK_SHARED_SECRET']
  ZENDESK_SUBDOMAIN     = ENV['ZENDESK_SUBDOMAIN']

  def create
    if user = User.authenticate(params[:login], params[:password])
      # If the submitted credentials pass, then log user into Zendesk
      sign_into_zendesk(user)
    else
      render :new, notice: 'Cannot find user with that username or passowrd.'
    end
  end

  private

  def sign_into_zendesk(user)
    iat = Time.now.to_i
    jti = "#{iat}/#{SecureRandom.hex(18)}"

    payload = JWT.encode({
                           iat: iat, # Seconds since epoch, determine when this token is stale
                           jti: jti, # Unique token id, helps prevent replay attacks
                           name: user.name,
                           email: user.email
                         }, ZENDESK_SHARED_SECRET)

    redirect_to zendesk_sso_url(payload)
  end

  def zendesk_sso_url(payload)
    url = "https://#{ZENDESK_SUBDOMAIN}.zendesk.com/access/jwt?jwt=#{payload}"
    url += '&' + { return_to: params['return_to'] }.to_query if params['return_to'].present?
    url
    binding.pry
  end
end

嘗試在redirect_to之前調用binding.pry

  def sign_into_zendesk(user)
    iat = Time.now.to_i
    jti = "#{iat}/#{SecureRandom.hex(18)}"

    payload = JWT.encode({
                           iat: iat, # Seconds since epoch, determine when this token is stale
                           jti: jti, # Unique token id, helps prevent replay attacks
                           name: user.name,
                           email: user.email
                         }, ZENDESK_SHARED_SECRET)

    binding.pry

    redirect_to zendesk_sso_url(payload)
  end
