Python socket.timeout

我在啓動時運行一個腳本，並持續每秒用Python編寫。它可以在有限的時間內正常工作（似乎變化~5/10分鐘），然後產生以下錯誤波紋管。Python socket.timeout

我還沒有嘗試改變睡眠時間，因爲這是一個「測試」腳本，但我將使用必須每秒運行的腳本，以便試圖找到正確的方式來做到這一點。

谷歌似乎對答案的方式很少，也許我使用了錯誤的術語，但我不確定它的睡眠時間可能是ping IP的失敗時間？

import time, urllib2

    except urllib2.URLError as err: pass 
    return '<img class="right" src="networkoff.png" width="32" height="32">' 

output = internet_on()  
f = open('/var/www/html/viv/wifiout.html', 'w')

你的問題似乎與缺乏連接有關，這可能是2個問題之一：代理或缺乏來自目標服務器的響應。第一個問題與python中的腳本不使用機器上的憑證有關，因此，如果你有自己的代理，它將不會進行身份驗證並提供錯誤。 –

那麼沒有代理設置或使用如此的目標服務器問題。原因是什麼？這是谷歌的知識產權，所以我使用它，因爲它的大小不會造成問題。 –

那麼，你完全確定你所使用的網絡不需要代理嗎？因爲這是企業網絡中非常普遍的問題。 –

Tr的y這：

import time, urllib2 

def internet_on(): 
    returnValue = '<img class="right" src="networkon.png" width="32" height="32">' 
    try: 
     response=urllib2.urlopen('http://64.233.160.94',timeout=1) 
    except: 
     returnValue = '<img class="right" src="networkoff.png" width="32" height="32">' 
    return returnValue 


while True: 
    output = internet_on() 
    with open('/var/www/html/viv/wifiout.html', 'w') as f: 
     f.write(output) 
    time.sleep(5)

time.sleep在幾秒鐘內收到一個參數，爲什麼你要等待1000秒？ –

看起來像JQuery'1000'呃？哈，讓我試試看。 –

我把它固定到只有5秒鐘，這對於網絡在連接之間稍微喘息一點來說應該是個好時機。 –
