提问
我正在使用python的email.message_from_string解析原始电子邮件.但是,邮件中有多个“已接收”标头.当我调用message.keys()时,它们显然是几个已接收的标头.但是,当我尝试message.get(“ Receiveved”)时,我只会得到“”一个空字符串.您如何获取该标头的那些实例的值？最佳答案
get_all(name[, failobj])Return a list of all the values for the field named name. If there are no such named headers in the message, failobj is returned (defaults to None).
