Hello,
I encountered strange behavior during HTTP response.
I need to set custom header Access-Control-Allow-Origin:*.
To do that I am using custom response.
Following code is working and set required header:
declare
%rest:POST("{$json}")
%rest:path("/ping")
function drpg:ping(
$json as xs:string
) as element()* {
<http:response status="200" message="OK">
<http:header name="Access-Control-Allow-Origin" value="*"/>
<http:header name="Content-Type" value="text/html"/>
</http:response>
</rest:response>,
let $p := json:parse($json)
return ($p/json/data/_/_/_)[last()]
};
Response header:
Access-Control-Allow-Origin
*
Content-Length
11
Content-Type
text/html;charset=utf-8

I want to return plain text, so when I change return parameter to xs:string* and add data function header from rest:response is overwritten.
Response header:
Content-Length
6
Content-Type
application/xml; charset=UTF-8

Example code:
declare
%rest:POST("{$json}")
%rest:path("/drpg/ping")
function drpg:ping(
$json as xs:string
) as xs:string* {
<http:response status="200" message="OK">
<http:header name="Access-Control-Allow-Origin" value="*"/>
<http:header name="Content-Type" value="text/html"/>
</http:response>
</rest:response>,
let $p := json:parse($json)
return data(($p/json/data/_/_/_)[last()])
};
Why does header is overwritten ? I think if header is set explicitly it shouldn't be overwritten.
