Question

我有以下脚本，我将其作为文本获取: http://pastebin.com/c8XHN27N

如何使用正则表达式从中剪切/提取所需的 URL？

我需要从上面的脚本中获取下一个值:t="https://s3.amazonaws.com/s3.maketutorial.com/users/7a75f78cb4644e4188ad82d063b1f54b/settings.txt"

不知道这是不是你想要的。但这将帮助您从脚本文件中提取所有网址

var src = "...";
var reg = /(\b(https?|ftp):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/gim
var urls = src.match(reg);
console.log(urls);
/* [
    "http://www.walkme.com/",
    "https://localhost/mt/resources/",
    "https://localhost/mt/lib/maketutorial_lib.js",

] */
