Hi Taras,
I think you need to make sure whether it is the call with xdmp:http-delete()
that is causing the problem, or that it is a syntax problem in the xquery that
does the call. Try putting a try-catch clause around the xdmp:http-delete,
something like:
try {
xdmp:http-delete(...)
} catch ($e) {
$e
}
If the outcome doesn't change with this try-catch then your problem is not
caused by the call with xdmp:http-delete..
Just to clarify, the http-delete call does indeed only send a request to a http
server, sending along any information you supply, like for instance the request
parameter 'uri' you added to the url. Inside the xquery you are calling on the
localhost, you will have to capture the details from that request and find out
how the request wants you to act and respond. Use the xdmp:get-request-method()
to determine whether someone sent a DELETE request.
If you want your xquery to act by deleting the document identified by the uri
parameter, you probably want to do something like:
xdmp:document-delete(xdmp:get-request-field('uri'))
Also note that it is safer to apply the fn:encode-for-uri function on the
document uri before sending it along with the HTTP request. It gets decoded
automatically by the MarkLogic HTTP server.
Kind regards,
Geert
PS: I assume you have good reason to send a http request for deleting a
document from the database, instead of just calling xdmp:delete-document
directly..
