如何在MarkLogic XQuery中获取HTTP POST主体？

Question

I'm trying to use the exist-db request:get-data() method to get the post data of a request. However, I'm getting the error:

XDMP-UNDFUN: (err:XPST0017) Undefined function request:get-data()

I did declare the namespace in my header. I don't understand why I still can't use request:get-data() or any of the other request: functions

declare namespace request="http://exist-db.org/xquery/request";
declare option exist:serialize "method=xml media-type=text/xml indent=yes";

let $post-data := request:get-data()
return $post-data

Answer 1

我想你正在寻找xdmp：get-request-body 。

Sam pointed you to the function you need, but I wanted to respond to another part of your question:

Each XQuery processing engine implements standard functions , but there is other functionality needed that is not defined by the standard. For MarkLogic, you'll use standard functions with the fn: prefix.

Each XQuery engine then defines additional functions that will be needed. For Exist DB, some of those are in the " http://exist-db.org/xquery/request " namespace, while MarkLogic uses " http://marklogic.com/xdmp " for a lot of its extension functions.

When you're looking for the MarkLogic equivalent of an Exist DB-specific function, search on http://docs.marklogic.com -- start with the function name, and if that doesn't work, search for the terms that describe what you're trying to do.
