在混合任务中使用Bamboo发送电子邮件

当我运行这个混合任务时,我得到以下日志输出:

21:20:26.829 [debug] Sending email with Bamboo.LocalAdapter:

%Bamboo.Email{assigns: %{}, bcc: [], cc: [], from: {nil, 
"me@example.com"}, headers: %{}, html_body: "Welcome",
private: %{}, subject: "Welcome!!!", text_body: "welcome", to: 
[nil: "foo@example.com"]}

** (exit) exited in: GenServer.call(Bamboo.SentEmail, {:update, 
    #Function<2.18788267/1 in Bamboo.SentEmail.push/1>}, 5000)
    ** (EXIT) no process: the process is not alive or there's no 
    process currently associated with the given name, possibly

我怎样才能解决这个问题？Bamboo在凤凰应用中运行良好.我无法让它在混合任务中运行.

发生此错误是因为bamboo未启动.

启动单个应用程序

在您的情况下,使用Application.ensure_all_started/2启动特定的应用程序:

Application.ensure_all_started(:bamboo)

启动所有应用程序

在某些情况下,您可能希望启动所有应用程序: Mix.Tasks.App.Start将启动mix.exs配置中定义的所有应用程序:

defmodule Mix.Tasks.SendEmails.Reminder do
  use Mix.Task
  import Mix.Ecto
  import Ecto.Query

  def run(_args) do
    Mix.Tasks.App.Start.run([]) # This will start all apps
    Foobar.welcome_email |> MyApp.Mailer.deliver_now
  end
end
