Hi,

   I have a link and am getting the csv file when i do in the terminal. I would like to do that in rails controller. I need the authentication also.

Here is the link

   " wget --user=test --password=test https://demo.service-now.com/incident_list.do\\?CSV"

Please help me. I was struck with this issue.

It is important to remember that one cannot necessarily expect a rapid reply from a mailing list. At any time about one third of the population of the world is asleep and another third is working. Of the remaining third the vast majority know nothing of RoR or have better things to do than monitor the list. Unfortunately that appears to leave just you and me and I don't know the answer, other than to suggest using system() or backticks which is probably not the best way.

It is best to wait 24 hours before bumping a question.

Have you considered the fact that if you do this in the controller then the user will not get a response from his action until the get has completed and you do the next render?

If I grok in fullness, what you are asking is essentially "how do I open a file by URL, in Ruby?" Googling "ruby open url" (sans quotes) yields some promising hits. Summary: check out net::http, and open-uri. I didn't read it in enough detail to see how it handles authentication (if at all), but at least it's a starting point. Maybe Googling "ruby open authenticated url" might be useful? I'll leave that as an exercise for the reader. :wink:

You can just execute any bash command by including command within `` in your controller. For example in your case 'wget --user=test --password=test https://demo.service-now.com/incident_list.do\\?CSV'
