用groovy读取IMAP消息内容字符串

| 嗨，我正在使用我的grails应用程序，但我通过imap连接到gmail并等待收到的电子邮件。当电子邮件到达时，我需要获取其内容，并且它应该是字符串。然后，我需要将此字符串与一个正则表达式匹配以获取最有价值的数据。问题是此字符串有问题，它与我在常规的多行groovy字符串上测试过的regexp不匹配，并且一切正常。 
def processMessage(def imapMessage){
  if(message && message instanceof IMAPMessage){
              def content = message.getContent()
              println \'Content =\'+ content
              m_mailContent = content
              println \'m_mailContent is \' + m_mailContent
          }
接着 
def getType(){
       def type = 0 
       if(utility.ParseUtil.matches(m_mailContent, WEB_SERVICE_REGEXP)){
          type = 1
       }else if(utility.ParseUtil.matches(m_mailContent, BNET_REGEXP)){
           type = 2
       }else if(utility.ParseUtil.matches(m_mailContent, QUEUED_REGEXP)){
           type = 3
       }
        return type
    }
But i almost always get type = 0
我可能需要对该字符串做一些事情。我不知道我得到什么样的琴弦。打印时，一切似乎都很好。当然，其中可能包含一些特殊字符，但是我可以将它们转义吗？ 
def WEB_SERVICE_REGEXP = /.*ErrorID:\\s*[A-Za-z\\d\\/\\.-]*\\n.*Time:\\s*[A-Za-z\\d\\/\\s:]*\\n.*URL:\\s*[A-Za-z\\d\\/\\.]*\\n/
我从gmail获得的字符串就是这样

我试着像这样 
//ParseUtil
static def matches(String str, def regexp){
            def m  = str =~ regexp
            m.find()
        }
我希望现在已经很清楚了。

    我希望现在已经很清楚了。 我找到了答案。在我的正则表达式中，我搜索\“ \\ n \”作为换行符，它确实适用于我伪造的Java字符串以测试解析，但是在gmail（纯文本内容类型）的电子邮件正文中，我应该搜索\“ \\ r \\ n \“。现在可以使用了！我很开心！ 感谢您的所有回复。对此，我真的非常感激。

    细屠截殴些

    如果将ѭ8更改为： 
    def WEB_SERVICE_REGEXP = /(?m)^ErrorID:\\s*([A-Za-z0-9\\-]+)$[\\n]^Time:\\s*([A-Za-z\\d\\/\\s:]*)$[\\n]^URL:\\s*([A-Za-z\\d\\/\\.]*)$/
    编辑 这是我所拥有的： 
    def message = \'\'\'

static def matches( String str, def regexp ){
  def m  = str =~ regexp
  m.find()
}

println matches( message, WEB_SERVICE_REGEXP )
    然后打印 
    true

    穗揣

    更改： 
    static def matches(String str, def regexp){
            def m  = str =~ regexp
            m.find()
        }
    至： 
    static def matches(String str, regexp){
       (str =~ regexp)
}
