Question

我正在尝试在rails应用程序中使用twilio。作为开发的一部分，我使用一些硬编码值设置了一个简单的控制器（提交POST请求的表单中的输入基本上被忽略）。这是控制器的代码：

class SmsController < ApplicationController

def send (dummy)

twilio_sid = "removed-for-privacy-reasons"
twilio_token = "removed-for-privacy-reasons"
twilio_phone_number = "removed-for-privacy-reasons"
number_to_send_to = "removed-for-privacy-reasons"

@twilio_client = Twilio::REST::Client.new twilio_sid, twilio_token

@twilio_client.account.sms.messages.create(
    :from => twilio_phone_number,
    :to => number_to_send_to,
    :body => "This is a test of SendTextController"
)

end
end

控制器工作正常 - 我在手机上收到了硬编码短信。但是，我在网络表单中收到以下异常：

未定义的方法`空？＆＃39; for Twilio :: REST :: SMS ::消息：0x007f8df0e743b8

有another SO thread reporting a similar problem，但那里提供的解决方案都不适用于我。你能帮忙吗？

Answer 1

Twilio Evangelist在这里。

这真的很有趣。

首先快速注意：您使用的是SMS资源which is deprecated in favour of Messages。您应该使用以下内容：

@twilio_client = Twilio::REST::Client.new twilio_sid, twilio_token

@twilio_client.account.messages.create(
  :from => twilio_phone_number,
  :to => number_to_send_to,
  :body => "This is a test of SendTextController"
)

注意我删除了.SMS部分。

其次，我承认我无法完全解释细节，我强烈怀疑使用send因为你的行动名称正在调用各种混乱。 #send来自Object，在这里你覆盖它，但Rails将它用于控制器上的各种不同回调。我注意到您已将(dummy)添加到您的签名中，但Ruby doesn't support method overloading。

我不知道为什么，但似乎可能成为问题。我用你的控制器创建了一个简单的Rails 4.0.4，我有一个类似的问题：

undefined method `compile' for #<Twilio::REST::SMS::Message:0x007fea132761e0>

Rails.root: ~/so26076867

我的rails应用程序没有ActiveRecord，因此可以解释一些差异。但是注意到堆栈跟踪的顶部都来自Rails中的回调代码。当我将动作重命名为test_sms时，它起作用了：

def test_sms
  twilio_sid = "xxxx"
  twilio_token = "yyyy"
  twilio_phone_number = "zzzz"
  number_to_send_to = "...."

  @twilio_client = Twilio::REST::Client.new twilio_sid, twilio_token

  @twilio_client.account.sms.messages.create(
    :from => twilio_phone_number,
    :to => number_to_send_to,
    :body => "This is a test of SendTextController"
  )   
end

我有兴趣听听这是否适合你。我偶然在命名方法send时看到Ruby和Rails中的奇怪行为，它似乎总是会引起混乱。究竟为什么你会收到这个错误，我不确定。这可能会破坏Rails中的某些东西。我将在本周调查一下，看看能否弄明白。

让我知道这是否有效，否则我会有另一个裂缝。

xmjw的回答指出了它。我得到了来自Twilio支持的Alex Chan的同样建议。然而，Xmjw的答案更全面，因为它提到了已弃用的API版本。

我需要提一下，我从Twilio's own blog复制了控制器的代码，但我没有特别重新命名控制器方法来“发送”。代码产生“错误的参数数量（1表示0）”，因此我在“发送”方法中添加了一个虚拟参数。

我遵循了Xmjw和Alex Chan的建议并重新命名了控制器方法。我在Twilio博客的代码片段中使用了名称“send-text_message”。我开始得到“缺少模板”，但这与twilio无关。把

head :ok

在send_text_message方法的末尾

删除了该错误消息。我从Template is missing的一个回复中得到了这个。

简而言之 - Twilio博客上的代码片段有些过时，但是对于Xmjw和twilio的Alex Chan的回复将其排除在外。看到对Twilio API的这种良好支持真的很令人鼓舞。我很高兴与它合作 - 谢谢你们，伙计们！
