我正在实现griddler(使用Mandrill)在我的应用程序中获取电子邮件。

这是我接收邮件的班级

#app/email_receivers/incoming.rb
 class EmailReceiver < Incoming::Strategies::Mandrill
   def receive(mail)
    %(Got message from #{mail.to.first} with subject "#{mail.subject}")
   end
  end

  req = Rack::Request.new(Rails.env)
  result = EmailReceiver.receive(req) 

这是我的rails控制器,它调用EmailReceiver类的接收方法。

#emails_controller.rb
 class EmailsController < ActionController::Base
   def create
    if EmailReceiver.receive(request)
     render :json => { :status => 'ok' }
    else
     render :json => { :status => 'rejected' }, :status => 403
    end
   end
 end

调用EmailsController的create方法的路由

#routes.rb
 Rails.application.routes.draw do
   post '/emails' => 'emails#create'
 end

注意: - 在生产环境中运行服务器后

rails s -e production

我收到了这个错误

/home/bvc-2/.rvm/gems/ruby-2.2.1/gems/rack-1.6.4/lib/rack/request.rb:192:in `[]=': string not matched (IndexError)

where&#34; puts req&#34;在

req = Rack::Request.new(Rails.env) 

原来是:

#<Rack::Request:0xc3bace8 @env="production">

我的config / application.rb文件是: -

require File.expand_path('../boot', __FILE__)

require 'rails/all'

 # Require the gems listed in Gemfile, including any gems
 # you've limited to :test, :development, or :production.
 Bundler.require(*Rails.groups)

 ActionMailer::Base.smtp_settings = {
:address =>"smtp.gmail.com",
:port => 587,
:domain => "gmail.com",
:user_name =>  "***@gmail.com",
:password => "pass*******",
:authentication => 'plain',
:enable_starttls_auto => true
}
 module ComplaintSystem
 class Application < Rails::Application

  # Settings in config/environments/* take precedence over those specified  here.
  # Application configuration should go into files in config/initializers
  # -- all .rb files in that directory are automatically loaded.

  # Set Time.zone default to the specified zone and make Active Record    auto-convert to this zone.
  # Run "rake -D time" for a list of tasks for finding time zone names.    Default is UTC.
  # config.time_zone = 'Central Time (US & Canada)'
    config.active_job.queue_adapter = :delayed_job
    config.time_zone = 'Mumbai'
    config.active_record.default_timezone = :local
    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # Do not swallow errors in after_commit/after_rollback callbacks.
      config.active_record.raise_in_transactional_callbacks = true
 end
end

当您尝试错误地将string变量作为Hash访问时,会发生此类错误。

s = "hello world"
s["position"] = "programming is fun"
# > IndexError: string not matched
# > from (irb):5:in `[]='
# > from (irb):5

查看完整的堆栈跟踪,看看您尝试进行此类操作的位置。
