marklogic - Marklogic 8 rest 拡張機能の multpart/form-data とファイルのアップロードの問題

Question

基本的にMLコンテンツデータベースにアップロードされたファイルを保存するML8で小さな休息拡張機能を作成しました..これを行うと、次の例外が発生します

<error-response xmlns="http://marklogic.com/xdmp/error">
<status-code>500</status-code>
<status>Internal Server Error</status>
<message-code>INTERNAL ERROR</message-code>
<message>XDMP-UPDATEFUNCTIONFROMQUERY: xdmp:function(fn:QName("http://marklogic.com/rest-api/resource/repoLoad","post"), "/marklogic.rest.resource/repoLoad/assets/resource.xqy")($context, $service-params, $input) -- Cannot apply an update function from a query . See the MarkLogic server error log for further detail.</message>
</error-response>

しかし、宣言オプション xdmp:update "true"; を設定しました。以下はコードです..

module namespace repoLoad = "http://marklogic.com/rest-api/resource/repoLoad";

declare namespace rapi = "http://marklogic.com/rest-api";

declare default function namespace  "http://www.w3.org/2005/xpath-functions";
declare option xdmp:mapping "false";
declare option xdmp:update "true";

(: Function responding to GET method - must use local name 'get':)
declare function repoLoad:get($context as map:map, $params  as map:map) as document-node()*
{
    repoLoad:notSuportedMsg($context)
};

(: Function responding to PUT method - must use local name 'put'. :)
declare function repoLoad:put($context as map:map, $params  as map:map, $input as document-node()*) as document-node()?
{
    repoLoad:notSuportedMsg($context)
};

(: Func responding to DELETE method - must use local name 'delete'. :)
declare function repoLoad:delete($context as map:map,$params  as map:map) as document-node()?
{
    repoLoad:notSuportedMsg($context)
};

(: Function responding to POST method - must use local name 'post'. :)
declare function repoLoad:post($context as map:map, $params  as map:map,$input as document-node()*) as document-node()*
{
    let $filename := xdmp:get-request-field-filename("upload")
    let $contentType := xdmp:get-request-field-content-type("upload")
    let $log := xdmp:log("File Name : " || $filename)
    let $log := xdmp:log("Content Type : " || $contentType)


    let $uri := "/documents/"||$filename
    let $_ := xdmp:document-insert($uri, xdmp:get-request-field("upload"),(xdmp:default-permissions()), ("raw"))

    let $output := json:object()
    let $_ := (
        map:put($output, "Name", $filename),
        map:put($output, "Mime-Type", $contentType)
    )
    return document {xdmp:to-json($output)}

};



declare private function repoLoad:notSuportedMsg($context as map:map) as document-node()*
{
    let $_ := map:put($context, "output-status", (501, "Not Supported HTTP method"))
    let $output := json:object()
    let $errorResponse := json:object()
    let $_ := (
        map:put($errorResponse, "statusCode", 501),
        map:put($errorResponse, "message", "Not Supported HTTP method")
    )
    let $dummpy := map:put($output, "errorResponse", $errorResponse )
    return document {xdmp:to-json($output)}
};

以下は、ログファイルのエラートレースです。

MarkLogic REST 拡張機能は、リクエストメソッドと単一/複数ステートメントに応じて、デフォルトで特定の更新モードで実行されます。MarkLogic 8 以降、POST メソッドの単一ステートメントのデフォルトの更新モードがに変更されましたquery。repoLoad:post次のように、メソッドに注釈を追加します。

declare %rapi:transaction-mode("update") function repoLoad:post(...)
