问题
I give my production server IP address as App domain in facebook application but it's not saved. It returns error as App domain is not valid. So that I cannot use my facebook connect API.
Can we give IP address as App domain in FB application? If it's not, what is the other way to do?
回答1:
No, it looks like the app domain can only be a domain and not an ip address.
For example in the app settings page, near the App Domain hover the '?' and see:
Enable auth on domains and subdomain(s)
Also, I found this page: http://developers.facebook.com/docs/appproperties/ it refers to the REST api and so it's not that up to date, but it clearly states there that there are two different properties: base_domain(s) and ip_list.
I suggest that you try to put a normal domain and see what happens.

This is what I found works.
From the Facebook development page "Apps-YourAppName", click on Basic in the LEFT Nav.
There are 3 sections on this page: Basic Info, Cloud Services, and "Select how your app integrates with Facebook"
In the Select how your app integrates with Facebook section, select "Website"
Enter your fully qualified domain name in the Site URL dialog box. Example: http://www.mydomain.com OR http://mydomain.com (my site does not include the www so I didn't add it).
At the bottom of the page click the "Save Changes" button. You may receive a notice that it may take several minutes to blah blah blah....but you can continue with the next steps immediately.
Now, in the Basic Information section at the top of this screen, you can now add your App Domain. This should be formatted as mydomain.com. Do not add "http://" and do not add "/" at the end of the domain name.
NOTE: My site does not use the www, so I cannot confirm that it's required in Step #6. Try it both ways if you're unsure.
At the bottom of the page click the "Save Changes" button. You may receive a notice that it may take several minutes to blah blah blah....but you can continue with the next steps immediately.
At this point the error was NOT displayed as it was before.
Hope this helps!

One solution to getting over the problem of using an IP address as a valid domain is to use: xip.io
xip.io is a magic domain name that provides wildcard DNS for any IP address
Simply add .xip.io after your url and use this as the domain name. Perfect for me as I do my development on a virtual machine!

If you don't have a domain (only the IP) just leave the "App Domains" field in blank. It works! =)
This, IMHO, is Facebook's fault as the error message is really confusing and makes you think only domains are allowed.
Hope it helps someone! =)
