当自定义控制器方法在 Rails 中触发操作邮件程序时出现 500 错误(在 Heroku 上)

Question

我的应用程序在单击按钮时会发送电子邮件，这在开发中工作正常，但在生产(Heroku(上进行测试时出现500错误

日志指向与端口的连接或允许我创建的自定义 POST 方法来启用触发器有关，但我无法破译它。任何指示或帮助将不胜感激。

按钮单击失败的日志：

控制器：

class GifsController < ApplicationController
protect_from_forgery except: [:email, :show], prepend: true
skip_before_action :verify_authenticity_token
before_action :set_gif, only: [:show, :edit, :update, :destroy]

def email
@gif_email = params[:gif_email]
GifMailer.with(gif_email: @gif_email).nearby_email.deliver_now
end
helper_method :email
...
end

邮件：

class GifMailer < ApplicationMailer
default from: "jack@xxxxxxxx"
def nearby_email
@gif_email = params[:gif_email]
mail(to: @gif_email, content_type: "text/html", subject: "Hello in there", body: "Hello in there", template_path: 'app/views/layouts/mailer.html.erb' )

生产.rb 邮件设置：

config.action_mailer.perform_caching = false
config.action_mailer.delivery_method = :smtp
host = 'xxx.xxxxx'
config.action_mailer.default_url_options = { host: host }
config.action_mailer.smtp_settings = {

问题在于应用程序的配置方式。我正在使用Jumpstart Rails平台，该平台可以进行大量后台配置。不幸的是，它不允许我使用Gmail，所以我不得不使用另一个第三方电子邮件服务。

对于任何对Jumpstart有相同问题的人在：

1. 注册支持的电子邮件服务之一，我使用了邮戳，请获取您的 api 密钥
2. 在 rails 中输入凭据：编辑 --环境=生产
3. 删除生产中可能具有的任何自定义 SMTP 配置设置.rb
4. 完成您正在使用的任何平台的授权流程
5. 利润
