Hello,

I encounter a problem with a RESTXQ application, perhaps someone can help me?

Goal: Download a file with an encoding dependent on a user entry. The request contains form parameters.

Attempt:

I can control the encoding using the %output annotation. However, this annotation must be a literal string, I think. Therefore I tried web:forward, as well as web:redirect, thus triggering the execution of a function with the desired %output declaration.

Issue: the form parameters get lost.

How to achieve the goal? Thank you for your advice.

With kind regards,

Hans-Jürgen

declare %output:method("text")

%output:encoding("utf-8")

%rest:path("/util/download/text")

%rest:form-param("text", "{$text}", "")

%rest:form-param("file-name", "{$fileName}", "text.txt")

%rest:form-param("encoding", "{$encoding}", "utf-8")

function f:downloadText(

$text as xs:string,

$fileName as xs:string,

$encoding as xs:string) {

if ($encoding eq 'cp1252') then web:forward('/util/download/text-cp1252')

else ...

declare %output:method("text")

%output:encoding("cp1252")

%rest:path("/util/download/text-cp1252")

%rest:form-param("text", "{$text}", "")

%rest:form-param("file-name", "{$fileName}", "text.txt")

function f:downloadTextCp1252(

$text as xs:string,

$fileName as xs:string) {

let $text := replace($text, '
', '
')

return (

<rest:response>

<http:response status="200">

<http:header name="Content-Disposition" value='attachment; filename="{$fileName}"'/>

<http:header name="Content-Language" value="en"/>

<http:header name="Content-Type" value="text/csv; charset=cp1252"/>

</http:response>

</rest:response>,

$text

)

};

PS: The <http:header> seems to be without effect - experiments seemd to show that I have to use the %output declaration.
