解析“来自”的电子邮件地址和“至” Ruby中的字段

问题描述

在电子邮件中，看起来像从或到字段可以包含一个或多个地址，每个地址可以像[email protected]或John D Jr< [email protected]>

所以一个从字段可以看起来像以下任何一种：

 [email protected]
 
a @ a .com，Bob Blue< [email protected]  
 
Abe Allen< [email protected]> [email protected]
 
Abe Allen< [email protected]> Bob Blue< [email protected]> 
 
Abe Allen< [email protected]> Bob Blue< [email protected]> [email protected]
  pre> 
 
 
等等。
 
 
 
我想解析这些字段，提取每个地址的电子邮件，如果它有效，以及名称（如果有）。由于我不熟悉电子邮件标准，我可能会缺少一些可以看到什么地址字段的情况。有没有一个Ruby库可以做到这一点？
解决方案
是的，有一个宝石为此;它被称为  。
  require'mail'
 
 addresses = [] 
 raw_addresses = Mail :: AddressList.new（Abe Allen< [email protected]> Bob Blue < [email protected]> [email protected]）
 
 raw_addresses.addresses.each do | a | 
 address = {} 
 
 address [：address] = a.address 
 address [：name] = a.display_name如果a.display_name.present？ 
 
地址<<<地址
 end 
  
 
In an email, it looks like a "from" or "to" field can contain one or more addresses, each address can be like "[email protected]" or "John D Jr <[email protected]>"
So a "from" field can look like any of the following:
"[email protected]"

"[email protected], Bob Blue <[email protected]>"

"Abe Allen <[email protected]>, [email protected]"

"Abe Allen <[email protected]>, Bob Blue <[email protected]>"

"Abe Allen <[email protected]>, Bob Blue <[email protected]>, [email protected]"
and so on.
I want to parse these fields, extracting each address' email if it's valid, and the name if it's present. Since I'm not familiar with the email standard, I may be missing some cases of what address fields can look like. Is there a Ruby library that can do this?
 解决方案 
Yes, there's a gem for this; it's called mail.
require 'mail'

addresses = []
raw_addresses = Mail::AddressList.new("Abe Allen <[email protected]>, Bob Blue <[email protected]>, [email protected]")

raw_addresses.addresses.each do |a|  
  address = {}

  address[:address] = a.address
  address[:name]    = a.display_name if a.display_name.present?

  addresses << address      
end
