To use the script:

git clone https://github.com/bknarendra/fb_photo_friend_finder.git
cd fb_photo_friend_finder
bundle install

You need to get the FB access token to allow uploading temporary photos to FB. Use the Graph API Explorer to get a token that has the permissions publish_actions and user_photos. Copy and paste the access token in the script.

Next you need the FB cookies.

• Open facebook.com in Chrome and login.
• Then open Developer Tools and switch to Network Tab.
• Reload the page.
• Right click on any request which goes to facebook.com and select Copy as cURL option. It will copy that request as a cURL command.
• Paste it in some editor. It will look something like this. curl 'https://www.facebook.com/photo.php?fbid=&set=' -H 'accept-encoding: gzip, deflate, sdch, br' -H 'accept-language: en-US,en;q=0.8' -H 'authority: www.facebook.com' -H 'cookie: cookies' --compressed
• Copy the cookie block (everything in '' which has cookie written)
• Paste that in the script and save.

To run the script.

ruby photo_friend_finder.rb "path to the photo"
