Windows上的Ruby网络问题

Question

I am running windows XP with ruby 1.8.6 patchlevel 111. I am using HTTP to connect to a remote server and it has been running fine. All of a sudden it started to through the exception listed below (I did not change any code since the last time I ran it successfully). Does anybody know what is going on?

Answer 1

Maybe the remote host is down? Or a new firewall has been put between your machine and the remote host?

"Timeout::Error" usually points to that direction.

Answer 2

besides the obvious (firewall, you got blacklisted for bad user-agent or ignoring robots.txt), you can try curl

http://curl.haxx.se/libcurl/ruby/

OR increase net/http timeout to say, 30+ seconds

Answer 3

It could be related to this known Ruby bug where Timeout::Error does not subclass Exception. (fixed in 1.9.2 I believe)

It can be fixed by rescuing from Timeout::Error like rescue Timeout::Error => e
