如何在Skype来电时程序性地暂停Spotify

Question

Skype有一个内置功能，当有电话打进来时，它会自动暂停和恢复iTunes的播放。如果Spotify也能有类似的功能就好了。两者都提供了Python的接口，所以用这个方法来实现看起来是个不错的选择。

我尝试用Python来实现这个功能。它在后台运行，像个守护进程一样，当有电话打进来时，会暂停或恢复Spotify的播放。这个程序使用了Skype和Spotify的Python库：

http://code.google.com/p/pytify/
https://developer.skype.com/wiki/Skype4Py

import Skype4Py
import time
from pytify import Spotify

# Create Skype object
skype = Skype4Py.Skype()
skype.Attach()

# Create Spotify object
spotify = Spotify()
spotifyPlaying = spotify.isPlaying()

# Create handler for when Skype call status changes
def on_call_status(call, status):
  if status == Skype4Py.clsInProgress:
    # Save current spotify state
    global spotifyPlaying
    spotifyPlaying = spotify.isPlaying()

    if spotify.isPlaying():
      print "Call started, pausing spotify"
      # Call started, pause Spotify
      spotify.stop()

  elif status == Skype4Py.clsFinished:
    # Call finished, resume Spotify if it was playing
    if spotifyPlaying and not spotify.isPlaying():
      print "Call finished, resuming spotify"
      spotify.playpause()  

skype.OnCallStatus = on_call_status

while True:
  time.sleep(10)
