Hi Amit,
The built-in routing is intended to use main as the default function, so this
path: "/topics" would normally go to the topics' controller's main function,
while "/topics/topics" would go to the topics function in the topics
controller. I see that you want the simpler URL path to go to the topics
function instead.
I played around with your example for a bit and I got it to work by changing
the endpoint:
<request uri="^/topics/?(.*)$" endpoint="/roxy/query-router.xqy">
<uri-param name="controller" default="topics"></uri-param>
<uri-param name="func">topics</uri-param>
<uri-param name="format" default="json"></uri-param>
<http method="GET"/>
<http method="HEAD"/>
</request>
The endpoint can't point to the controller itself, because the target needs to
be a main module. I see that you had it pointing to "/app/restful-router.xqy".
I don't know what that one does, but it doesn't need to do much. You might want
to just copy the src/roxy/query-router.xqy code into there and see how that
works (better not to directly point to code under src/roxy, as that can change).
Dave.

Subject: [MarkLogic Dev General] Roxy request not getting properly redirected.
Hi All,
I am using a roxy configuration and I created an endpoint routing like this to
the list of existing routing definitions:
<request uri="^/topics/?(.*)$" endpoint="/app/restful-router.xqy">
<uri-param name="controller" default="topics"></uri-param>
<uri-param name="func">topics</uri-param>
<uri-param name="format" default="json"></uri-param>
<http method="GET"/>
<http method="HEAD"/>
</request>
and I created a controller named topics.xqy, a model named topics-model.xqy and
views topics
This is how my topics contoller looks like
xquery version "1.0-ml";
module namespace c = "http://marklogic.com/roxy/controller/topics";;
import module namespace ch = "http://marklogic.com/roxy/controller-helper";
at "/roxy/lib/controller-helper.xqy";
import module namespace req = "http://marklogic.com/roxy/request"; at
"/roxy/lib/request.xqy";
import module namespace error = "http://marklogic.com/roxy/error-lib"; at
"../views/helpers/error-lib.xqy";
import module namespace topics = "http://marklogic.com/roxy/models/topics"; at
"/app/models/topics-model.xqy";
declare option xdmp:mapping "false";
declare variable $RES-TYPE as xs:string := "Topics";
declare variable $ALL-FORMATS as xs:string+ := ("html", "xml", "json", "text");
(: Default function that is returns an error message :)
declare function c:main() as item()*
{
error:error-handling( 500, fn:concat("Not supported, not sure why"))
};
declare function c:topics() as item()*
{
let $result := topics:topics("RBO-TOPIC-ROOT","parents","", "ALL")
return (
ch:use-view("topics/topics",$ALL-FORMATS),
ch:add-value("result", $result),
ch:add-value(
"res-header",
element header {
element Date {fn:current-dateTime()},
element Location {fn:concat("/",fn:lower-case($RES-TYPE),())},
element Content-Type {req:get("req-header")/content-type/fn:string()}
}
)
)};
The model has the code of getting me the topics as per my application
requirement.
When I make a request through postman like this http://localhost:8018/topics it
always goes to the main function and throws the error, and never goes to the
desired topics function. Why is that so? What mistake am I doing. Please
suggest.
Best Regards
Amit
