ruby mailgun发送邮件失败，400个错误请求

Question

我正在用 ruby​​ 尝试 mailgun API。我做的第一件事就是注册一个帐户。我有 api_key 和沙盒域处于活动状态。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 个错误的请求，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 mailgunner.rb:24:in `send_simple_message'
    from mailgunner.rb:33:in `<main>'

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

Answer 1

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

 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。
