how to deal with socket.error: (10060, 'Operation timed out')

2006-03-18 Thread JuHui 
I wrote a script to get 100 pages from a server.
like below:

1:import httplib
2:conns = httplib.HTTPConnection(www.mytest.com)
3:conn.request(GET, /)

sometimes a socket error was raised.

  File D:\usr\bin\lib\httplib.py, line 627, in connect
raise socket.error, msg
socket.error: (10060, 'Operation timed out')

how to catch this kind of error then retry the GET operation?

btw:
If I want to get many page on same server, which lib is the best
choice? I only know httplib,urllib and urllib2.
thanks a lot.

what the best way to get 1000 page on same server?

2006-03-18 Thread JuHui 
Hi :
 I want to get many html page on same server.
 I have tried httplib and urllib.
 I think httplib is better one because it's httplib.HTTPConnection. It
will establish one network connection then do other opration before
connection close. The urllib will establish network connection each
time request. Am I wrong? How about urllib2? how about a new socket
client for this requirement?
  is there any other lib shall I use for this requirement?
  Any suggestion are welcome.

2006-03-18 Thread JuHui 
thanks!
I try the try before, but can't catch the socket error. so strange,
maybe my code was error.
I wrote a retry code block as below.

import httplib,time

while 1:
try:
conn = httplib.HTTPConnection(www.test.com)
conn.request(GET, /)
print success
break
except:
print error
time.sleep(2)
