我正在尝试检查jpg的URL是否真实。此代码有效,如果jpg存在,则返回True
:
import httplib
def exists(site, path):
conn = httplib.HTTPConnection(site)
conn.request('HEAD', path)
response = conn.getresponse()
conn.close()
return response.status == 200
print exists('uploads1.wikiart.org',
'/images/vincent-van-gogh/vincent-s-bedroom-in-arles-1889.jpg')
但是,如果我将其发送到不存在的网址,例如'uploads1111.wikiart.org',
,我会收到一个套接字错误:
socket.error: [Errno 10060] A connection attempt failed
because the connected party did not properly respond after a period of time
我搜索了一个答案,发现与errno
模块有关,但无法成功地将该代码应用到我自己的代码中。我正在尝试捕获任何套接字错误并返回False
(如果有)。
答案 0 :(得分:1)
回答我自己的问题:
import httplib
import socket
def exists(site, path):
try:
conn = httplib.HTTPConnection(site)
conn.request('HEAD', path)
response = conn.getresponse()
conn.close()
return response.status == 200
except socket.error:
return False
