不是最好的解決方案,但它有效:
func (h *HookHandler) NewEvents() http.HandlerFunc {
eventsLocker := struct {
v bool
mux *sync.Mutex
}{
v: true,
mux: &sync.Mutex{},
}
return func(w http.ResponseWriter, r *http.Request) {
if !eventsLocker.v {
w.WriteHeader(http.StatusLocked)
return
}
w.WriteHeader(http.StatusAccepted)
go func() {
defer eventsLocker.mux.Unlock()
defer func() { eventsLocker.v = true }()
eventsLocker.mux.Lock()
eventsLocker.v = false
time.Sleep(2 * time.Second)
}()
}
}
