Question

突然间我从我的代码中得到以下错误，前一段时间它运行得很好。它是由互联网连接引起的吗？

 #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

Answer 1

尝试在请求块中声明超时，即;

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

通过这样做，你最有可能摆脱这个错误：）

Errno 101网络无法访问
