Mailchimp gem double_optin 假的不起作用

Question

双重选择加入确认电子邮件仍然通过，知道出了什么问题吗？长臂猿宝石有问题，所以选择了 mailchimp 宝石。

Answer 1

来自 mailchimp-api 文档

subscribe（id， email， merge_vars = nil， email_type = 'html'， double_optin = true， update_existing = false， replace_interests = true， send_welcome = false） ⇒ 哈希

double_optin是将直接传递的参数，而不是像您所做的那样。

所以，它将是：

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

Answer 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)
