Net::HTTP get timeout in Ruby

问题

How can I set a larger timeout in net/http? What I'm doing is this:

rta = JSON.parse(Net::HTTP.get(URI(url)))

I've tried:

uri = URI(url)
http = Net::HTTP.new(uri.host, uri.port)
http.open_timeout = 5* 60
http.read_timeout = 5* 60
rta = JSON.parse(Net::HTTP.get(URI(url)))

but it still doesn't work.

回答1:

It looks like it probably isn't working because you're making your get call on the Class instead of the instance you created. Try changing that last line to:

rta = JSON.parse(http.get(URI(url)))

回答2:

Maybe you can use OpenURI :

require 'open-uri'
open(url, :read_timeout => 5 * 60) do |file|
  rta = JSON.parse file
  # ...
end
