我/正在使用Lita创建一个聊天机器人，我创建了一个名为dialog的句柄，我选择将我的代码分开，我的聊天路由在lita-dialog/lib/lita/handlers/dialog.rb中，我的响应在lita-dialog/bin/main.rb中。
lita-dialog/lib/lita/handlers/dialog中的代码
module Lita
module Handlers
class Dialog < Handler
# insert handler code here
route(/.*hello|hi|good morning|morning|welcome.*/i, :greeting_response, command: true)
Lita.register_handler(self)
end
end
end
lita-dialog/bin/main.rb中的代码
require_relative '../lib/dialog.rb'
def greeting_response(response)
greetingresponse = [
'Hello',
"Greetings, #{response.user.name}.",
"Well hello there, #{response.user.name}.",
"Hey #{response.user.name}, Hello!",
"Good day, #{response.user.name}",
'Hi.'
]
response.reply(greetingresponse.sample)
end
我正在使用 RSpec 测试我的代码并且测试通过，但是当我测试机器人以获得我没有收到的响应和预期的响应时，我得到了预期的响应
Type "exit" or "quit" to end the session. │<rive/Microverse/Ruby/jaybot lita-dialog/spec/lita/handlers/dialog_spec.rb ruby utf-8 16% ☰ 1/6 : 1
jaybot > jaybot hello │6 lines yanked
jaybot >
测试
require "spec_helper"
describe Lita::Handlers::Dialog, lita_handler: true do
it { is_expected.to(route_command('hello').to(:greeting_response)) }
it { is_expected.to_not(route('hello').to(:greeting_response)) }
end
这是我在处理程序文件夹中运行机器人时获得的输出

这个答案归功于吉米·夸德拉
您展示的 Lita处理程序定义了一个路由，当传入消息匹配时，该路由将调用名为
greeting_response的实例方法。没有定义该名称的实例方法，因此出现"未定义方法"异常。您在另一个文件中定义了具有此名称的方法，但在顶级范围内定义的方法与类中的实例方法不同。如果希望该方法包含在 Lita处理程序类中，则应在包含在处理程序中的模块中定义它。
