Question

我在.Net中使用[Url(UrlOptions.DisallowProtocol)]数据注释属性来检查URL正则表达式（对于https / http或www不是必需的）。此属性的代码如下所示：

string const regex = new RegExp('^((https?|ftp):\/\/)?(((([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-fA-F]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|([a-zA-Z][\-a-zA-Z0-9]*)|((([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-zA-Z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-zA-Z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-fA-F]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-fA-F]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-fA-F]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-zA-Z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-fA-F]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$');

我想将其转换为JS验证，但面临很多困难，因为这是一个很长的验证。

是否有任何工具或任何简单的方法可以将此正则表达式转换为在JS中运行？

Answer 1

正则表达式似乎在某种程度上可以在Javascript中使用而无需任何修改 - 请参阅regex101 demo。如果在单引号的Javascript字符串中定义它，请记住要转义所有反斜杠（\\代替\）和单引号（''而不是'）： / p>

注意：i修饰符假设这需要不区分大小写的匹配。 （如果上述情况不充分，请更具体地说明哪些措施不起作用。）

我知道唯一可以在正则表达式之间进行转换的通用工具是RegexBuddy - 但它是为软件支付的（29.95欧元） - 尽管如果由于任何原因它不起作用你可以得到一个退款。

var Ismatch = Regex.Match(input, YourRegEx , RegexOptions.IgnoreCase);

if (Ismatch .Success)
 {
  // does match
 }

您可以尝试将此正则表达式放在@＆＃34;＆＃34;
