Question

我试图使用Marklogic Java API将xquery转换加载到Modules DB中。最初，我以前使用正常工作的同一段代码来加载Javascript转换（.sjs）。现在，当我尝试使用相同的代码加载xquery转换时，它不起作用。

我的Xquery转换：

xquery version "1.0-ml";

module namespace test =
  "http://marklogic.com/rest-api/transform/deepan";

declare function test:transform(
  $context as map:map,
  $params as map:map,
  $content as map:map
) as map:map*
{
    let $jsoncont := xdmp:from-json-string($content)

    let $inputval := "fname,lname"
    let $orig-value := map:get($jsoncont, "value")

    let $jscode := "var simple = require('/wdsUtils.sjs');
                    var content, input;
                    simple.createUri(content,input);"

    let $uri := xdmp:javascript-eval($jscode,('content',$orig-value,'input',$inputval))
    map:put($content, "uri",$uri)
    map:put($content, "value",$orig-value)
    return $content  

};

我要加载转换的Java代码：

    private static final String TRANSFORM_NAME = "sec";
    static String HOST = "localhost";
    static int PORT = 8136;
    static String USER = "admin";
    static String PASSWORD = "admin";
    private static DatabaseClient client = 
            DatabaseClientFactory.newClient(
                HOST, PORT, new DigestAuthContext(USER, PASSWORD));


    public static void loadLookup() throws FileNotFoundException 
    {

        TransformExtensionsManager extensionsManager=client.newServerConfigManager().newTransformExtensionsManager();
        FileInputStream fileInputStream=new FileInputStream("C:/Users/deepan/Desktop/sec.xqy");
        //System.out.println(fileInputStream.toString());
        InputStreamHandle handle=new InputStreamHandle(fileInputStream);
        //extensionsManager.writeJavascriptTransform(TRANSFORM_NAME, handle);
        extensionsManager.writeXQueryTransform(TRANSFORM_NAME, handle);
        client.release();

    }

例外：

似乎您的代码中有语法错误。更改为此，它应该可以工作：

...
let $uri := xdmp:javascript-eval($jscode, ('content', $orig-value, 'input', $inputval))
let $_ := map:put($content, "uri", $uri)
let $_ := map:put($content, "value", $orig-value)
return $content
...

我在map：put表达式前面添加了let $_ :=。

您的名称空间名称（秒）和转换名称（deepan）也不匹配：

module namespace test =
  "http://marklogic.com/rest-api/transform/sec";

declare function test:transform
...

转换函数的另外一个接口必须与此匹配：

declare function yourNS:transform(
  $context as map:map,
  $params as map:map,
  $content as document-node())
as document-node()

将您的更改为以下内容：

declare function test:transform(
  $context as map:map,
  $params as map:map,
  $content as document-node()
) as document-node()
