ruby-on-rails - Faye 服务器错误 - 未定义方法 - 传入

Question

在 faye.ru 中，我有带有 faye_token 的代码:

require 'faye'
require File.expand_path('../config/initializers/faye_token.rb', __FILE__)

Faye::WebSocket.load_adapter('thin')

class ServerAuth
  def incoming(message, callback)
    if message['channel'] !~ %r{^/meta/}
      if message['ext']['auth_token'] != FAYE_TOKEN
        message['error'] = 'Invalid authentication token.'
      end
    end
    callback.call(message)
  end
end

faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 45)
faye_server.add_extension(ServerAuth.new)
run faye_server

如果我在终端中运行此代码:

rackup faye_alt.ru -E production -s thin

如果我刷新本地主机网站 - 我会出现此错误:

[ERROR] [Faye::RackAdapter] undefined method `[]' for nil:NilClass

有什么想法吗？请帮忙!

Answer 1

消息['ext']为零。您可以通过

检查您的 message['ext'] 是否为零

def incoming(message, callback)
  if message['channel'] !~ %r{^/meta/}
    if message['ext'].nil? || message['ext']['auth_token'] != FAYE_TOKEN
      message['error'] = 'Invalid authentication token'
    end
  end
callback.call(message)
end

上面的答案是错误的，您需要清除消息['ext']['auth_token']是为了清除身份验证 token ，这样它就不会泄露给客户端。

def outgoing(message, callback)
  if message['ext'] && message['ext']['auth_token']
    message['ext'] = {} 
  end
callback.call(message)
end
