在我的代碼中，我os.Interrupt在關閉之前收聽了以下內容package mainimport (    "net/http"    "os"    "os/signal"    "syscall")var passer *DataPasserconst maxClients = 1func init() {    passer = &DataPasser{        data:       make(chan sseData),        logs:       make(chan string),        connection: make(chan struct{}, maxClients),    }}func main() {    http.HandleFunc("/sse", passer.HandleSignal)    go http.ListenAndServe(":1234", nil)    // Listen to Ctrl+C (you can also do something else that prevents the program from exiting)    c := make(chan os.Signal, 1)    signal.Notify(c, os.Interrupt, syscall.SIGTERM)    <-c    if client.IsConnected() {        client.Disconnect()    }}這passer.HandleSignal是一個將 SSE 發送Server Sent Event到客戶端的函數，如下所示：package mainimport (    "fmt"    "net/http")type sseData struct {    event, message string}type DataPasser struct {    data       chan sseData    connection chan struct{} // To control maximum allowed clients connections}func (p *DataPasser) HandleSignal(w http.ResponseWriter, r *http.Request) {    w.Header().Set("Content-Type", "text/event-stream; charset=utf-8")    w.Header().Set("Cache-Control", "no-cache")    w.Header().Set("Connection", "keep-alive")    fmt.Println("Client connected from IP:", r.RemoteAddr)    p.connection <- struct{}{}    flusher, ok := w.(http.Flusher)    if !ok {        http.Error(w, "Internal error", 500)        return    }    fmt.Fprint(w, "event: notification\ndata: Connection to WhatsApp server ...\n\n")    flusher.Flush()    // Connect to the WhatsApp client    go Connect()    for {        select {        case data := <-p.data:            fmt.Println("recieved")        我的問題是，如果用戶使用 Ctrl+C 中斷了應用程序，該main函數正在響應它，我需要它向它發送數據，parser以便處理程序向客戶端發送服務器已關閉的通知
