【问题描述】：

我有一个带有 Rails 和 Anycable 的 Docker 设置。只有在 production 中 request.params 不返回任何内容。在开发中，这不是问题。

如果我尝试连接到wss://api.test.to:8443/live?uid=yyy&token=xxx

进行了连接尝试，但在我的connection.rb 中，request.params 始终返回一个空对象。

这是我相当标准的connection.rb。

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :current_user

    def connect
      self.current_user = find_verified_user
    end

    private

    def find_verified_user
      auth_header = request.params[:token]
      uid_header = request.params[:uid]

      logger.debug(request.params[:token]) # logs nothing
      logger.debug(request.to_yaml) # logs request object with no parameters included.
      
      begin
        decoded = JsonWebToken.decode(auth_header) 
      rescue JWT::VerificationError, JWT::ExpiredSignature, JWT::DecodeError => error_string
        logger.debug("AUTH ERROR: " + error_string.to_s)
        return reject_unauthorized_connection # If decoding the JWT failed, reject auth.
      end
      
      user_decoded = User.find(decoded[:user_id])

      if user_decoded.id === uid_header
        return user_decoded
      else
        return reject_unauthorized_connection
      end
    end
    
  end
end

这是建立 websocket 连接时记录的内容：

【参考方案1】：

我能够通过升级到最新版本的 anycable-rails > 1.0 来解决这个问题
