Question

我使用Google Apps脚本解析邮箱。我在识别要解析的消息时没有遇到任何问题，当我想从消息的plainBody中获取特定的文本块时，问题就出现了。

平原身份的摘录：

Technical details of permanent failure: 
Google tried to deliver your message, but it was rejected by the server for the recipient domain domain.com by aspmx.l.google.com. [173.194.77.26].

The error that the other server returned was:
550-5.1.1 The email account that you tried to reach does not exist. Please try
550-5.1.1 double-checking the recipient's email address for typos or
550-5.1.1 unnecessary spaces. Learn more at

----- Original message -----

X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed;
        d=1e100.net; s=20130820;

我试图抓住所有以550开头的行（至少，在本例中他们以550开头，可能是任意数量的代码开始这些行）

我试图抓住它的代码是

var bodyRegex = new RegExp("The error that the other server returned was:[\s\S]*----- Original message -----");
Logger.log(bodyRegEx.exec(plainBody));

它只是返回 null

使用RegExLib我能够成功使用此RegEx

尝试转义斜杠，因为您正在编译RegExp对象：

var bodyRegex = new RegExp("The error that the other server returned was:[\\s\\S]*----- Original message -----");

或只使用文字：

var bodyRegex = /The error that the other server returned was:[\s\S]*----- Original message -----/;

使用Google Apps脚本和正则表达式在两个其他字符串之间抓取字符串
