RESTXQ functions by default will match regardless of the HTTP Method being used in the request. You can however restrict whether a function can execute or not based on the request's HTTP Method.

1. Restricting Function Invocation by HTTP Method

XQRS Supports the following HTTP Methods:
GET, HEAD, POST, PUT, DELETE, OPTIONS and PATCH. To restrict a function to using a particular HTTP method add the annotation to the function. Consider the following example

declare
  %rest:path("/factory/warehouse/wheel/{$wheel-id}")
  %rest:POST
function post-wheel($wheel-id as xs:integer) {
  create-wheel($wheel-id)
};

declare
  %rest:path("/factory/warehouse/wheel/{$wheel-id}")
  %rest:GET
function get-wheel($wheel-id as xs:integer) {
  retrieve-wheel($wheel-id)
};

In the above example, the post-wheel function would only be invoked for POST requests to a URI like /factory/warehouse/wheel/1234. Where as the get-wheel function would only be invoked if the Request was a GET Request.

2. Multiple HTTP Methods

For simplicity's sake, you can add multiple HTTP Method annotations to a function, ensuring that it can only be invoked when the Request Method matches one of them.

In the following example, the get-or-post function could only be invoked if the HTTP Request method was of type GET or POST

declare
  %rest:path("/generic/{$name}")
  %rest:POST
  %rest:GET
function get-or-post($name as xs:string) {
  <hello>{$name}</hello>
};
