通过 Search/QueryBuilder API 检索 AEM 页面属性

Question

有没有办法通过 QueryBuilder API 检索作为页面元数据（页面属性）存储在单独 JCR 节点中的数据？

例子：

搜索结果应包含 ~/article-1/jcr:content/thumbnail 下的数据。但是，我得到的唯一结果是 ~article-1/jcr:content/content（模板中包含的 parsys）下的数据。

一个示例查询：

http://localhost:4502/bin/querybuilder.json?p.hits=full&path=/content/path/to/articles

结果（sn-p）：

{
   "jcr:path":"/content/path/to/articles/article-1",
   "jcr:createdBy":"admin",
   "jcr:created":"Tue Dec 03 2013 16:26:51 GMT-0500",
   "jcr:primaryType":"cq:Page"
},
{
   "jcr:path":"/content/path/to/articles/article-1/jcr:content",
   "sling:resourceType":"myapp/components/global/page/productdetail",
   "jcr:lockIsDeep":true,
   "jcr:uuid":"4ddebe08-82e1-44e9-9197-4241dca65bdf",
   "jcr:title":"Article 1",
   "jcr:mixinTypes":[
      "mix:lockable",
      "mix:versionable"
   ],
   "jcr:created":"Tue Dec 03 2013 16:26:51 GMT-0500",
   "jcr:baseVersion":"24cabbda-1e56-4d37-bfba-d0d52aba1c00",
   "cq:lastReplicationAction":"Activate",
   "jcr:isCheckedOut":true,
   "cq:template":"/apps/myapp/templates/global/productdetail",
   "cq:lastModifiedBy":"admin",
   "jcr:primaryType":"cq:PageContent",
   "jcr:predecessors":[
      "24cabbda-1e56-4d37-bfba-d0d52aba1c00"
   ],
   "cq:tags":[
      "mysite:mytag"
   ],
   "jcr:createdBy":"admin",
   "jcr:versionHistory":"9dcd41d4-2e10-4d52-b0c0-1ea20e102e68",
   "cq:lastReplicatedBy":"admin",
   "cq:lastModified":"Mon Dec 09 2013 17:57:59 GMT-0500",
   "cq:lastReplicated":"Mon Dec 16 2013 11:42:54 GMT-0500",
   "jcr:lockOwner":"admin"
}

搜索配置是开箱即用的默认配置。

编辑：数据以 JSON 格式返回，但是无法在 API 中访问：

结果：

{
   "success":true,
   "results":2,
   "total":2,
   "offset":0,
   "hits":[
      {
         "jcr:path":"/content/path/to/articles/article-a",
         "jcr:createdBy":"admin",
         "jcr:created":"Tue Dec 03 2013 16:27:01 GMT-0500",
         "jcr:primaryType":"cq:Page",
         "jcr:content":{
            "sling:resourceType":"path/to/components/global/page/productdetail",
            "_comment":"// ***SNIP*** //",
            "thumbnail":{
               "jcr:lastModifiedBy":"admin",
               "imageRotate":"0",
               "jcr:lastModified":"Wed Dec 04 2013 12:10:47 GMT-0500",
               "jcr:primaryType":"nt:unstructured"
            }
         }
      },
      {
         "jcr:path":"/content/path/to/articles/article-1",
         "jcr:createdBy":"admin",
         "jcr:created":"Tue Dec 03 2013 16:26:51 GMT-0500",
         "jcr:primaryType":"cq:Page",
         "jcr:content":{
            "sling:resourceType":"path/to/components/global/page/productdetail",
            "_comment":"// ***SNIP*** //",
            "thumbnail":{
               "jcr:lastModifiedBy":"admin",
               "imageRotate":"0",
               "fileReference":"/content/dam/path/to/IBMDemo/apparel/women/wsh005_shoes/WSH005_0533_is_main.jpg",
               "jcr:lastModified":"Mon Dec 09 2013 17:57:58 GMT-0500",
               "jcr:primaryType":"nt:unstructured"
            }
         }
      }
   ]
}

实现代码：

searchCriteria.put("path", path);
searchCriteria.put("type", "cq:Page");

searchCriteria.put("p.offset", offset.toString());
searchCriteria.put("p.limit", limit.toString());
searchCriteria.put("p.hits", "full");
searchCriteria.put("p.properties", "thumbnail");
searchCriteria.put("p.nodedepth", "2");

PredicateGroup predicateGroup = PredicateGroup.create(searchCriteria);
Query query = queryBuilder.createQuery(predicateGroup, session);
SearchResult result = query.getResult();

for (Hit hit : result.getHits()) {
    try {
        ValueMap properties = hit.getProperties();

        VFSearchResult res = new VFSearchResult();

        res.setUrl(hit.getPath());
        res.setImageUrl((String)properties.get("thumbnail"));
        res.setTags((String[])properties.get("cq:tags"));
        res.setTeaserText((String)properties.get("teaserText"));
        res.setTitle((String)properties.get("jcr:title"));

        searchResults.add(res);
    } catch (RepositoryException rex) {
        logger.debug(String.format("could not retrieve node properties: %1s", rex));
    }
}

Answer 1

在查询中设置好路径后，再设置一个或多个属性过滤器，如本例：

type=cq:Page
path=/content/path/to/articles
property=jcr:content/thumbnail
property.operation=exists
p.hits=selective
p.properties=jcr:content/thumbnail someSpecificThumbnailPropertyToRetrieve
p.limit=100000

您可以在 /libs/cq/search/content/querydebug.html 上设置它们，然后也可以使用它来获取同一查询的 JSON URL。

Answer 2

您可以使用CURL 以HTML/ JSON/ XML 格式检索节点属性。您所要做的就是安装下载 CURL 并从您的终端从与 curl 的 .exe 文件相同的目录运行您的 curl 命令。

HTML 示例：

C:\Users\****\Desktop>curl -u username:password http://localhost:4502/content/geometrixx-media/en/gadgets/leaps-in-ai.html

JSON 示例：

**C:\Users\****\Desktop>**curl -u username:password http://localhost:4502/content/geometrixx-media/en/gadgets/leaps-in-ai.html.tidy.infinity.json

注意：上述查询中的infinity 确保您以递归方式获取指定路径下每个节点的每个属性
