我有一个字符串如下：
string = "request=hxxp://abc.com/user=username?pass=password"
我需要将等号"="的第一个实例替换为"***"。我希望能实现：
string = "request***hxxp://abc.com/user=username?pass=password"
我测试了以下，但没有运气：
string = string.gsub(/^[^=]+(=)/,'***') # => "***hxxp://..."
string = string.gsub(/((?<=())=)/,'***') # => all "=" replaced with "***"
非常感谢任何帮助。

使用sub。这应该只替换Int32 nn = 4308;
VISITE v = VISITEs.FirstOrDefault(a => a.VINUM == nn);
DateTime d = (DateTime) v.DATEVIS;
Int32 p = (Int32) v.PANUM;
// First Select
var numberGroups = from n in VISRUBs.Where(a => a.VISANA.VISITE.DATEVIS <= d && a.VISANA.VISITE.PANUM == p)
group n by n.RUBRIQUE into g
select new {
RemainderCHAPLIB = g.Key.ANALYSE.CHAPITRE.LIBELLE,
RemainderLIB = g.Key.LIBELLE,
RemainderRUNUM = g.Key.RUNUM,
vals = from vlist in g.OrderByDescending(a => a.VISANA.VISITE.DATEVIS)
select vlist.VALEUR
};
//Second Select
var lst = from n in numberGroups.
ToList().Where(a => a.RemainderLIB != null)
select new {
RemainderCHAPLIB = n.RemainderCHAPLIB,
RemainderLIB = n.RemainderLIB,
RemainderRUNUM = n.RemainderRUNUM,
VAL = n.vals.FirstOrDefault(),
ANT = n.vals.Skip(1).FirstOrDefault()
};
的第一次出现。
=对于gsub，它必须是
string.sub(/=/, "***")
