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

    @mc = Mailchimp::API.new('mailchimp api key goes here')

    if !email.blank?

【解决方案1】：

来自mailchimp-api document

订阅（id，电子邮件，merge_vars = nil，email_type = 'html'，double_optin = true，update_existing = false，replace_interests = true，send_welcome = false）⇒ 哈希

double_optin 是直接传递的参数，不像你做的那样。

所以，它会是：

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

【讨论】：

我现在收到我尝试提交的任何电子邮件的 ex.message 错误。 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

【解决方案2】：

上面的答案一直给我错误，这对我有用：

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

尝试解释这个答案与上面的答案有何不同。作为对其他答案的评论，这可能会更好。
