testing123

我想获得每个领域(Return-path,Date,From,To等)以及body("testing123").

我尝试过匹配使用:

    var bodyRegex = /[\n]Subject: (.+)[\n](.+)/

但我得到空值.

Answer 1

试试这个:

码:

//var rePattern = new RegExp(/^Received:(.*)$/);
var rePattern = new RegExp(/^Subject:(.*)$/);

var arrMatches = strText.match(rePattern);

结果:

arrMatches[0] -> Subject: test
arrMatches[1] -> test
