ruby - twilio-ruby gem 在调用时是否采用 'from' 、 'to' 和 'url' 以外的参数？

Question

查看https://github.com/twilio/twilio-ruby/blob/master/lib/twilio-ruby/rest/calls.rb ，似乎只使用了“from”、“to”和“url”。如何传递“IfMachine”的值？例如，以下内容似乎不起作用。

# set ACCOUNT_SID and AUTH_TOKEN

twilioClient = Twilio::REST::Client.new(ACCOUNT_SID, AUTH_TOKEN)
twilioAccount = twilioClient.account
twilioAccount.calls.create({
    :from => 'from_number',
    :to => 'to_number',
    :url => '/url',
    'IfMachine' => 'Hangup'
})

# IfMachine parameter is not passed in the above request

Answer 1

设置 'IfMachine' => 'hangup' 对我有用。我认为 Twilio API 对参数值区分大小写。所以 'hangup' 会起作用，但 'Hangup' 可能不会。

这是我的 twilio-ruby session ，显示参数已正确传递:

irb(main):002:0> c.account.calls.create :from => '2158377932', :to => '4159334335', :url => 'http://demo.twilio.com/welcome/voice', 'IfMachine' => 'continue'
