我正试图在我的凤凰应用程序中创建一个邮件。我已经走得很远,但现在我正试图从iex控制台发送测试邮件,我收到以下错误:

iex(2)> Radios.Mailer.my_first_email("myemail@domain.com")
{:error, 400,
 "{\n  \"message\": \"'to' parameter is not a valid address. please check documentation\"\n}"}

mailer.ex

defmodule Radios.Mailer do
  use Mailgun.Client,
      domain: Application.get_env(:radios, :mailgun_domain),
      key: Application.get_env(:radios, :mailgun_key)

  def my_first_email(email_address) do
                send_email to: "email_address", #<= this appears to be the issue
                from: "test@example.com",
                subject: "My first email",
                text: "This is an email send with Phoenix and Mailgun"
  end
end

config.exs

config :radios,
  ecto_repos: [Radios.Repo],
  mailgun_domain: "https://api.mailgun.net/v3/XXXXXXXXX.mailgun.org",
  mailgun_key: "pubkey-XXXXXXXX"

我一直在把双引号更改为单引号,send_email(to: :email_address)并且还在那里添加了我自己的实际地址。

一切都没有快乐。

我错过了什么?

更新 已将 config.exs 更改为以下内容:

config :radios,  Radios.Mailer,
  mailgun_domain: "https://api.mailgun.net/v3/XXXXXXXX.mailgun.org",
  mailgun_key: "pubkey-XXXXXX"

但现在收到:

iex(1)> Radios.Mailer.my_first_email("myemail@domain.com")
** (FunctionClauseError) no function clause matching in IO.chardata_to_string/1
    (elixir) lib/io.ex:445: IO.chardata_to_string(nil)

             lib/client.ex:44: Mailgun.Client.send_without_attachments/2

1 个答案:

答案 0 :(得分:1)

有两个错误:

  1. email_address是一个变量,但您将字符串"email_address"传递给to的{​​{1}}参数。这样:

    send_email

    应该是:

    send_email to: "email_address",
    
  2. 您从env获取了错误的设置。设置存储在关键字列表send_email to: email_address, 中。

    此:

    Application.get_env(:radios, Radios.Mailer)

    应该是:

    use Mailgun.Client,
        domain: Application.get_env(:radios, :mailgun_domain),
        key: Application.get_env(:radios, :mailgun_key)
