问题
I'm developing an ajax based web site and I want to include a FB share function on the loaded content. The links use a hash tag and I can't manage to get the full links to show up when using the share function, I only get the domain url. Are hash tags not allowed or is there a special method for sharing such links?
回答1:
Use URL Encoding for the # character. Just replace the following:
http://www.example.com/#/path/to/whatever/
with:
http://www.example.com/%23/path/to/whatever/
This will allow you to pass the # to share on Facebook, Twitter, etc without getting stripped.

Take a look at Google's answer to the AJAX content problem, the hashbang.
Basically, on your AJAX page, set the hash to !/path/to/whatever/ – in other words,
http://www.example.com/#!/path/to/whatever/
Keep in mind your server must actually serve content similar to what you'd see in the AJAX application at http://www.example.com/path/to/whatever/.
I'm not sure if Facebook respects the hashbang, but it does at least solve Googlebot problems for you. Edit: It looks like Facebook doesn't support the hashbang. You'll probably have to set up a redirector page.
