語義網站ColdFusion cfhttp請求選項

Question

我正嘗試使用以下鏈接來獲取ColdFusion中RDF/XML格式的增強建議。

http://dev.iks-project.eu:8081/engines

我的問題是，該列表包含單詞反覆。我可以設置一些選項來獲得獨特的增強功能嗎？

您需要使用並熟悉Jena並知道如何使用Java內聯。那麼它只是一個例子：

<cfset oldModel = createObject("java", "com.hp.hpl.jena.rdf.model.ModelFactory").createDefaultModel().read("http://dev.iks-project.eu:8081/engines")> 
<cfset newModel = createObject("java", "com.hp.hpl.jena.rdf.model.ModelFactory").createDefaultModel()> 

<cfset sparqlQuery = "SELECT DISTINCT ?s ?p ?o WHERE {?s ?p ?o}"> 
<cfset triples = createObject("java", "com.hp.hpl.jena.query.QueryExecutionFactory").create(sparqlQuery, rdfModel).execSelect()> 

<cfloop condition="triples.hasNext()"> 
    <cfset nextTriple = triples.nextSolution()> 
    <cfset newModel.add(newModel.createStatement(nextTriple.getResource("s"), newModel.createProperty(nextTriple.getResource("p").getURI()), nextTriple.get("o")))> 
</cfloop> 

<cfset outputStream = createObject("java", "java.io.ByteArrayOutputStream")> 
<cfset newRdfXmlContent = newModel.write(outputStream, "RDF/XML-ABBREV").toString()>

本質上，在ColdFusion中執行此操作的最佳方法是循環訪問列表並創建ColdFusion結構。假設你的Web服務返回一個有效分隔的列表，這裏是如何的例子：

<cfset enhancements = "item1,item2,item3,item4,item1,item2,item3,item4"> 
<cfset objEnhancement = structNew()><!---- CREATE STRUCT---> 
<cfloop index="item" list="#enhancements#"><!---- LOOP THROUGH RESPONSE TEXT---> 
    <cfset objEnhancement[item] = ""><!---- CREATE STRUCT KEYS, THESE WILL AUTO DE-DUPE ---> 
</cfloop> 
<cfset uniqueEnhancements = StructKeyList(objEnhancement)> <!---- DUMP THE STRUCT KEYS TO A NEW LIST---->
