正常退出applescript運行終端nc命令

Question

我做了一個監聽某個端口的applescript。當它收到「開始」時，計算機開始從網絡攝像頭錄製，當它收到「停止」時，它停止錄製。

現在的問題是，我總是不得不強制退出這個應用程序。由於重複聲明？有沒有辦法繞過這個？我讀了一些關於閒置處理程序的內容，但對於我的應用程序繼續運行（沒有用戶點擊等）非常重要。

set recording to 0 
repeat 
set test to (do shell script "nc -l 2700") as string 

if test = "start" and recording = 0 then 
    tell application "QuickTime Player" 
     activate 
     new movie recording 
     document "Movie Recording" start 
     set recording to 1 
     delay 2 
    end tell 
else if test = "stop" and recording = 1 then 
    tell application "QuickTime Player" 
     document "Movie Recording" stop 
     set pad to path to desktop folder as string 
     set naam to (do shell script "date +%s") as integer 
     set extension to ".mov" 
     set all to pad & naam & extension 
     export document "Untitled" in file all using settings preset "720p" 
     delay 1 
     close document "Untitled" saving no 
     set recording to 0 
    end tell 
end if 
end repeat

你是對的idle handler。 return語句指定在調用處理程序之前應經過多少秒。確保將腳本保存爲保持打開的應用程序。

on idle 
    --insert your code 
    beep 
    return 10 
end idle
