Excerpts from Chris Double's message of Wed Nov 03 09:36:29 +0100 2010:
Are there any libraries available in Ur/Web for making HTTP requests
to other servers? I'd like to be able to call REST and JSON services
on a remote server and use the results in pages returned by an Ur/Web
app.
If there aren't any existing libraries, any thoughts on a good way of
doing this?
The C library curl is a possible solution which should be evaluated ?
Some APIs require HTTPs.
API's I've seen and used requiring HTTP(S) include SMS and payment serivces..
Yes, my first impulse would be to wrap a C library like cURL. Ur/Web is
designed so that every side-effecting action is _transactional_, so it
would help if the remote API you are asking is side-effect-free or
supports rolling back actions. Otherwise, you'll need to batch all
side-effecting actions to take place at once, after the current page
handler finishes.
The manual has documentation on the C FFI. If you want to go this
route, please feel free to post questions about it here.
