我第一次发帖，但我真的卡住了，需要帮助。
我目前正在开发一个家庭自动化系统，我想使用路由器控制远程 Arduino 设备。
这部分已经完成，我可以使用可以打开或关闭的浏览器连接到链接。我什至用它做了一个应用程序。
目前我正在研究一个语音识别代码，它需要一个代码然后翻译成语音，语音识别部分与 SpeechRecognition 库配合得很好，一旦 python 理解了代码，它必须给出一个命令并使用 url。
如果我尝试访问http://www.google.com之类的网址，我认为它可以工作，但是我的网址是“ http://192.168.0.227/LED=ON14 ”，并且在使用它时，程序会挂起然后超时，我已经尝试了几种方法来控制它，但它们似乎都不起作用。
import urllib2
sock = urllib2.urlopen("http://192.168.0.227/LED=ON14")
htmlSource = sock.read()
sock.close()
print htmlSource
这是我最近的试验

以该响应结束。
