What is the right syntax for Ruby to do a system call to curl?

Question

To refresh Redmine, I need SVN to ping our Redmine installation from our post-commit hook. Our post-commit hook is a Ruby script that generates an email. I'd like to insert a call do this:

curl --insecure https://redmineserver+webappkey

This call works from the command line but when I try to do this:

#!/usr/bin/ruby -w

REFRESH_DRADIS_URL = "https://redmineserver+webappkey"
system("/usr/bin/curl", "--insecure", "#{REFRESH_DRADIS_URL}")

It doesn't work. How do I do this in ruby? I googled 'ruby system curl' but I just got a bunch of links to integrate curl into ruby (which is NOT what I'm interested in).

Answer 1

system ("curl --insecure #{url}")

Answer 2

There are many ways

REFRESH_DRADIS_URL = "https://redmineserver+webappkey"
result = `/usr/bin/curl --insecure #{REFRESH_DRADIS_URL}`

but I don't think you have to use curl at all. Try this

require 'open-uri'
open(REFRESH_DRADIS_URL)

If the certificate isn't valid then it gets a little more complicated

require 'net/https'
http = Net::HTTP.new("amazon.com", 443)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE
resp, data = http.get("/")

Answer 3

For such a simple problem, I wouldn't bother with shelling out to curl, I'd simply do

require 'net/https'

http = Net::HTTP.new('redmineserver+webappkey', 443)

http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

http.get('/')

And for more complex problems, I'd still not shell out to curl, but rather use one of the many Ruby libcurl bindings.
