Accessing The Gmail RSS Feed With cURL On OSX Mavericks
There was an office gag I wanted to do that requried a small script that would speak a phrase every time an email with a certain title came through. After researching the various parts of the problem it looked like I could accomplish this with a couple of simple parts. Gmail offers an RSS feed for any unread items and any unread items with a specific tag at https://mail.google.com/mail/feed.atom. This seemed like it should be easy enough with a cURL request. Once I had the response from this I could kick off “say” with the phrase I wanted if data was present.
It turns out that on OSX Mavericks it isn’t quite to so easy to make a cURL request to Gmail because of updats that were made to crypto libraries that cURL uses. I asked a friend using Mountain Lion to run the same cURL request and it ran without problems. cURL states on its website that you should be able to pass the -k (–insecure) flag to the request and it should work without a problem. I am not sure why this wasn’t working but I believe somehow Google was doing something on their end that prevented the response I was expectring if the certificate wasn’t validated. I don’t know how they accomplished this but something was happening on their end. I ended up being able to piece together a solution and below are the steps I used to get this to work.
- Download the cer file from https://mail.google.com.
- There were great examples on how to do this in this stack overflow post.
- Add the cer file to OSX system keychain.
- Opened keychain
- File > Import Items
- opened .cer file downloaded from step 1.
- set all options on imported certificate to full allow.
- This didn’t work for me when I didn’t reboot.
- When I did reboot my keychain was hosed up. I deleted it and rebooted again.
- Gmail check should now work.
Here is the final script I created. Not much to look at but when it worked it got some good laughs at the office.
