ruby-on-rails - POPAuthenticationError - 从 Gmail 帐户轮询时出现 Mailman 错误

Question

我正在尝试启用我的 Rails 应用程序以接收来自 Gmail 帐户的电子邮件。我关注这个截屏视频:Receiving Email with Mailman .

我尝试对来 self 的 Gmail 帐户的电子邮件进行轮询，以便每次有人发送电子邮件时，我的应用程序都会收到该消息，然后相应地使用该消息更新数据库。

但是当我尝试运行“script/mailman_serve”来启动服务器和轮询时，我收到如下错误:

    from script/mailman_server:25:in `<main>'

这是我的 mailman_server 文件:

#!/usr/bin/env ruby
require "rubygems"
require "bundler/setup"
require "mailman"

#Mailman.config.logger = Logger.new("log/mailman.log")

Mailman.config.pop3 = {
  server: 'pop.gmail.com', port: 995, ssl: true,
  username: ENV["xxxxxx@gmail.com"],
  password: ENV["xxxxxx"]
}

Mailman::Application.run do
  default do
    begin
      Post.receive_mail(message)
    rescue Exception => e
      Mailman.logger.error "Exception occurred while receiving message:\n#{message}"
      Mailman.logger.error [e, *e.backtrace].join("\n")
    end
  end
end

有人能帮忙吗？谢谢!

我的 gmail 帐户也启用了 POP 设置，但仍然出现同样的错误。这是我的 POP 设置:

我只能在一种情况下重现错误。如果我有 username 空白。

如果您可以使用此代码进行调查。把它放在项目之外的任何地方，确保安装了 mailman gem 并运行文件两次。一旦硬编码用户名，第二次将其保留为 nil:

#!/usr/bin/env ruby
require "mailman"

username = ''                       
### OR ###
username = 'myownaddress@gmail.com'

puts "Using username='#{username}'..." 
Mailman.config.pop3 = {
  server: 'pop.gmail.com', port: 995, ssl: true,
  username: username, 
  password: 'password'
}
Mailman::Application.run do
  default do
    begin
      puts message 
    rescue Exception => e
      Mailman.logger.error "Exception occurred while receiving message:\n#{message}"
      Mailman.logger.error [e, *e.backtrace].join("\n")
    end
  end
end

使用空白用户名

Using username=''...

使用正确的电子邮件。

Using username='myownaddress@gmail.com'...
