Question

我正在尝试在rails 3应用程序中使用twitter gem，但不断收到以下错误：

TypeError: can't convert Pathname into String

这是我正在尝试运行的代码：

class Tweet < ActiveRecord::Base
  def self.test_tweet
    Twitter.user_timeline("sferik").first.text
  end
end

以下是完整的错误消息：

TypeError：无法将Pathname转换为String

即使从控制台运行相同的代码，我也会收到此错误：

Twitter.user_timeline("sferik").first.text

我使用相同版本的rails和twitter gem创建了一个空白的测试应用程序，它运行没有问题所以我不确定是什么问题。

Answer 1

当我在应用程序中使用它之前，我通过我的提交回过头来，直到我能找到一个点它是否正常工作以及我做了什么来打破它。

因此，如果有人碰巧处于同一位置，我添加的是config / initializers中的fix_ssl.rb文件，用于解决先前的SSL连接问题。删除此文件允许Twitter gem再次正常工作。

config/initializers/fix_ssl.rb

require 'open-uri'
require 'net/https'

module Net
   class HTTP
    alias_method :original_use_ssl=, :use_ssl=

    def use_ssl=(flag)
      self.ca_file = Rails.root.join('lib/ca-bundle.crt')
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag
    end
  end
