Errno 101网络无法访问

突然我从我的代码中得到以下错误，前一段时间它运行得很好。是否由互联网连接引起？Errno 101网络无法访问

#Get data checkpoint size 
url = 'http://url:8080/vrio/blk' 
r = requests.get(url) 
data = r.json() 



def counterVolume_one(): 
    wanted = {'Bytes_Written', 'Bytes_Written', 'IO_Operation'} 
    for d in data['Block Devices'].itervalues(): 
    values = {k: v for k, v in d.iteritems() if k in wanted} 
    print json.dumps(values) 



Traceback (most recent call last): 
    File "hyper.py", line 31, in <module> 
    r = requests.get(url) 
    File "/usr/lib/python2.7/dist-packages/requests/api.py", line 55, in get

该代码将不会运行。请发布导致错误的确切代码。此外，无法访问网络通常指向网络问题或主机名错误。 –

这是完整的代码，实际上前三行产生的错误代码的下一部分我无法测试，因为我无法访问网络 – Imo

尝试在请求块即声明超时时间;

r = requests.get(url, timeout=20)

这样做，你必须很有可能摆脱掉这个错误:)
