Ruby on rails Mailchimp gem double_optin false不工作

双重选择确认邮件仍然会通过，你知道怎么了吗？由于长臂猿宝石有问题，所以选择了mailchimp宝石

Gemfile

gem "mailchimp-api", "~> 2.0.4"

应用程序\u controller.rb

class ApplicationController < ActionController::Base

  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.

  protect_from_forgery with: :exception

  before_action :setup_mcapi

  def setup_mcapi
    @mc = Mailchimp::API.new('mailchimp api key goes here')
    @list_id = "list id goes here"
  end

end

class WelcomeController < ApplicationController
  def index
  end

  def subscribe
    email = params[:email][:address]

    if !email.blank?

      begin

        @mc.lists.subscribe(@list_id, {'email' => email}, 'double_optin' => false)
      end

      respond_to do |format|
        format.json{render :json => {:message => "Success!"}}
      end

    rescue Mailchimp::ListAlreadySubscribedError

      respond_to do |format|
        format.json{render :json => {:message => "#{email} is already subscribed to the list"}}
      end

    rescue Mailchimp::ListDoesNotExistError

      respond_to do |format|
        format.json{render :json => {:message => "The list could not be found."}}
      end

    rescue Mailchimp::Error => ex

      if ex.message

        respond_to do |format|
          format.json{render :json => {:message => "There is an error. Please enter valid email id."}}
        end

      else

        respond_to do |format|
          format.json{render :json => {:message => "An unknown error occurred."}}
        end
      end

    end

  else

    respond_to do |format|
      format.json{render :json => {:message => "Email Address Cannot be blank. Please enter valid email id."}}
    end

  end
end

end

从

订阅（id，email，merge\u vars=nil，email\u type=html，double\u optin=true，update\u existing=false，replace\u interests=true，send\u welcome=false）⇒ 散列

double_optin

是将直接传递的参数，与您所做的不同

因此，它将是：

@mc.lists.subscribe(@list_id, email, nil, 'html', false)

---

上面的答案不断给我错误，这对我很有用：

@mc.lists.subscribe(@list_id, { "email" => email }, merge_vars = nil, email_type = 'html', double_optin = false)

---

有了这些，我现在收到了我试图提交的任何电子邮件的前消息错误

rescue Mailchimp:：Error=>ex if ex.message respond_to do | format | format.json{render:json=>{:message=>“出现错误。请输入有效的电子邮件id.“}}}}end

尝试解释此答案与上述答案的不同之处。作为对另一个答案的评论，这可能更好。

@mc.lists.subscribe(@list_id, email, nil, 'html', false)

@mc.lists.subscribe(@list_id, { "email" => email }, merge_vars = nil, email_type = 'html', double_optin = false)
