net/ghttp: Server Domain if is empty str, bind handler pattern will add @ which is not expect

[elonnzhang]

Go version

go version go1.22.6 linux/amd64

GoFrame version

v2.7.1

Can this bug be reproduced with the latest release?

Option Yes

What did you do?

s.Domain(strings.Join(config.AppConfig().Server.Domains, ",")).Group()
if config.AppConfig().Server.Domains is empty, strings.Join(config.AppConfig().Server.Domains, ",") will be a empty str (""),
and in Bind logic

// Domain creates and returns a domain object for management for one or more domains.
func (s *Server) Domain(domains string) *Domain {
	d := &Domain{
		server:  s,
		domains: make(map[string]struct{}),
	}
	for _, v := range strings.Split(domains, ",") {
		d.domains[strings.TrimSpace(v)] = struct{}{}
	}
	return d
}

// BindHandler binds the handler for the specified pattern.
func (d *Domain) BindHandler(pattern string, handler interface{}) {
	for domain := range d.domains {
		d.server.BindHandler(pattern+"@"+domain, handler)
	}
}

for range domains, actually d.server.BindHandler(pattern+"@"+"", handler)
eg:
default | :8008 | POST | /api/db/sql/queryStream@

What did you see happen?

What did you expect to see?

if domains is emtpy, this domain setting is not needed.
binding url is default | :8008 | POST | /api/db/sql/queryStream not queryStream@
