I want to use an external service that regularly sends a POST request to my Ur/Web application containing text data as the body of the POST. I tried something like the following to log to a file:fun notifyMessage body = dml (INSERT INTO messages (Message) VALUES ({[body]})); return<xml>0</xml> Where 'messages' is a table containing the string that is the message. This won't build in Ur/Web because 'notifyMessage' has as side effect and Ur/Web is telling me to use it in a form. But the function isn't actually used anywhere in my application itself - it's POSTed to directly from an other service. How can I write something in Ur/Web to handle this POST?
This is one of the ugly parts of the current implementation, but there _is_ a fairly simple workaround pattern that I've employed.
Step 1: In another function (its name doesn't matter, since you won't expect anyone to access its page), create a dummy form that submits to [notifyMessage]. Step 2: In the signature of this module (i.e., the .urs file), include the dummy function but not [notifyMessage].
There may be a good way of supporting externally-callable forms without this sort of acrobatics, but, for now, this method isn't so bad.
