死机: http: /static/的多个注册

Question

请考虑这个问题：

我必须在独特的端口上启动多个监听器，例如：

function launchUI(self *myObject) {
    fs := http.FileServer(http.Dir(self.staticFs))
    http.Handle("/static/", http.StripPrefix("/static/", fs))
    go http.HandleFunc("/login", self.loginHandler)

    errx := http.ListenAndServeTLS(self.uiport, self.cert, self.key, nil)
    if errx != nil {
        fmt.Println("http Listen err", errx)
        panic("http Listen")
    }
}

listOfObjects := []*myObject{} 
for _, obj := range(listofObjects){
     obj.launchUI()
    <snip>
}    

其中每一个都在唯一的self.uiport上，我必须为每个对象提供/static/和/login。非常简单的东西。除非，如果我的listOfObjects中有多个项目，这将失败：

panic: http: multiple registrations for /static/ 

goroutine 7 [running]:
net/http.(*ServeMux).Handle(0x4da250, 0x2b8830, 0x1, 0x324f68, 0x12183a8)
    /usr/local/go/src/net/http/server.go:2403 +0x278
net/http.(*ServeMux).HandleFunc(...)
    /usr/local/go/src/net/http/server.go:2440
net/http.HandleFunc(...)
    /usr/local/go/src/net/http/server.go:2452
main.(*userStruct).startUI(0x10d6160)

你能教我怎么修这个吗？

function launchUI(self *myObject) {
    fs := http.FileServer(http.Dir(self.staticFs))
    mux := http.NewServeMux()
    mux.Handle("/static/", http.StripPrefix("/static/", fs))
    mux.HandleFunc("/login", self.loginHandler)

    errx := http.ListenAndServeTLS(self.uiport, self.cert, self.key, mux)
    if errx != nil {
        fmt.Println("http Listen err", errx)
        panic("http Listen")
    }
}
