用groovy讀取IMAP郵件內容字符串

Question

您好我正在處理我的grails應用程序，以至於我通過imap連接到gmail並等待收到的電子郵件。當電子郵件到達時，我需要獲取它的內容，它假設是一個字符串。然後，我需要將此字符串與正則表達式匹配以獲取最有價值的數據。問題是這個字符串有什麼問題，它不符合我在常規多行groovy字符串上測試的正則表達式，並且一切正常。

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 
      } 

然後

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 

我可能需要做一些事情該字符串。我不知道我得到了什麼樣的字符串。打印時，一切似乎都很好。當然，它可能是一些特殊的字符，但我逃脫它們？

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/ 

和一個字符串從Gmail得到的是這樣的

我嘗試馬赫像這樣

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

我希望這是一種明顯的現在。

      m.find() 
     } 

我希望現在有點清楚。

我找到了答案。在我的正則表達式中，我搜索「\ n」作爲斷路器，它確實在java字符串上工作，我僞造測試解析，但在Gmail的電子郵件正文（這是純文本/文本內容類型）我應該搜索「\ r \ n 」。它現在有效！我很開心！

非常感謝您的回覆。對此，我真的非常感激。

Answer 2

變化：

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

要：

如果你改變 WEB_SERVICE_REGEXP到

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

Answer 3

它的工作原理：

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\/\.]*)$/ 

編輯

以下是我有：

static def matches(String str, def regexp){

println matches(message, WEB_SERVICE_REGEXP) 

而且，打印

true
