go - 如何允许CORS使用多个端口？

Question

我遇到了此代码，并希望在端口1111、1112和1113上允许CORS，该怎么办？

router := mux.NewRouter().StrictSlash(true)
router.HandleFunc("/all", All).Methods("GET")
router.HandleFunc("/gotoT", Goto).Methods("GET")
headers := handlers.AllowedHeaders([]string{"X-Requested-With", "Content-Type", "Authorization"})
methods := handlers.AllowedMethods([]string{"GET", "POST", "PUT", "HEAD", "OPTIONS"})
origins := handlers.AllowedOrigins([]string{"*"})
log.Fatal(http.ListenAndServe(":1111", handlers.CORS(headers, methods, origins)(router)))

在此示例中， CORS仅在端口1111 和上监听，因此我想添加更多端口，请帮忙吗？

将它们放在单独的go例程中:

router := mux.NewRouter().StrictSlash(true)
router.HandleFunc("/all", All).Methods("GET")
router.HandleFunc("/gotoT", Goto).Methods("GET")
headers := handlers.AllowedHeaders([]string{"X-Requested-With", "Content-Type", "Authorization"})
methods := handlers.AllowedMethods([]string{"GET", "POST", "PUT", "HEAD", "OPTIONS"})
origins := handlers.AllowedOrigins([]string{"*"})

corsRouter := handlers.CORS(headers, methods, origins)(router)

go func() {
    log.Fatal(http.ListenAndServe(":1111", corsRouter))
}()

go func() {
    log.Fatal(http.ListenAndServe(":1112", corsRouter))
}()

log.Fatal(http.ListenAndServe(":1113", corsRouter))
