ruby mailgun 发送邮件失败，出现 400 错误请求

Question

我正在尝试使用 ruby​​ 的 mailgun API。我做的第一件事是注册一个帐户。我激活了 api_key 和沙箱域。然后，我将自己的电子邮件添加到沙盒域中的授权收件人。我在文档中所做的完全一样:

def send_simple_message
  RestClient.post "https://api:key-mykey"\
  "@api.mailgun.net/v3/sandboxe5148e9bfa2d4e99a1b02d237a8546fe.mailgun.org/messages",
  :from => "Excited User <postmaster@sandboxe5148e9bfa2d4e99a1b02d237a8546fe.mailgun.org>",
  :to => "my@email.com, postmaster@sandboxe5148e9bfa2d4e99a1b02d237a8546fe.mailgun.org",
  :subject => "Hello",
  :text => "Testing some Mailgun awesomness!",
  :multipart => true
end

send_simple_message

但它总是返回 400 错误请求，这是来自终端的跟踪:

/home/ys/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/rest-client-2.0.0/lib/restclient/abstract_response.rb:223:in `exception_with_response': 400 Bad Request (RestClient::BadRequest)

    from /home/ys/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/rest-client-2.0.0/lib/restclient/request.rb:215:in `execute'
    from /home/ys/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/rest-client-2.0.0/lib/restclient/request.rb:52:in `execute'
    from /home/ys/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/rest-client-2.0.0/lib/restclient.rb:71:in `post'
    from mailgunner.rb:24:in `send_simple_message'
    from mailgunner.rb:33:in `<main>'

我这里做错了什么？我安装了 rest-client gem，所以我认为我的注册有问题还是什么？

我遇到了类似的问题，在这里看到了文档: https://github.com/rest-client/rest-client (在异常(exception)部分)他们用救援包围了 RestClient.post。我把它打印出来了:

 def send_simple_message
   begin
     RestClient.post ...
   rescue RestClient::ExceptionWithResponse => e
     puts e.response
   end
 end

然后我得到一个错误字符串:

{"message": "'from' parameter is not a valid address. please check documentation"}

然后看到在我的测试中我在 from 字段中有一个错误:

:from => "Test <alert@mg.example.com", # missing '>' at the end 

也许您可以使用类似的方法来解决您的问题。
