如何在java/groovy中减少自定义API端点的输出

我正在改进Confluence Server平台的自定义搜索。我们有一个名为Scriptrunner的插件，它允许我们使用Groovy而不是Java来编写代码。

我正在处理的代码是一个搜索API端点，它目前运行良好，但返回了很多不必要的信息，甚至是重复的信息，所以我想以最有效的方式缩小搜索输出的范围。

该平台有一个javadoc，我正试图将其用于实现，链接：https://docs.atlassian.com/ConfluenceServer/javadoc/7.8.1/com/atlassian/confluence/search/v2/SearchManager.html

我想实现以下部分

search(ISearch search, Set<String> requestedFields)
Perform a search with a given criteria, the returns searchResults only have the fields requested in the projection filled out, no other fields are valid in the searchResult.

但我无法理解如何正确生成Set<String> requestedFields。

以下是我的尝试：

import...
def searchManager = ComponentLocator.getComponent(SearchManager)
def paramQueryString = "ArticleThatWillBeDeleted"
def query = BooleanQuery.andQuery(new TextQuery(paramQueryString));
def sort = new RelevanceSort();
def searchFilter = SiteSearchPermissionsSearchFilter.getInstance();
def searchContent = new ContentSearch(query, sort, searchFilter, 0, 100);
Set<String> requestedFields = new HashSet<String>();
requestedFields.add("displayTitle");
def searchresult = searchManager.search(searchContent,requestedFields)
return searchresult.getAll()

如果我想使用其他方法

search(ISearch search)
Perform a search with a given criteria.

这个脚本运行得很好，但返回了很多我想删掉的信息。

除了我想要实现的方法之外，我还对任何其他类型的建议持开放态度，在这些建议中，我只能指定我想要输出的信息，这样我就可以安全地输出大小和处理能力。

第页。S我已经试着在他们的社区页面上详细地问过同样的问题，但我认为我可以在这方面得到一些开发人员的帮助，因为我刚刚从这方面学到了Java/Govy。

以下是作为API端点实现的工作代码：

@BaseScript CustomEndpointDelegate delegate
testSearch(
    httpMethod: "GET", groups: ["access_group_1","access_group_2"]
) { MultivaluedMap queryParams, String body ->
    def searchManager = ComponentLocator.getComponent(SearchManager)
    // Query can be of any type noted here:
    //https://developer.atlassian.com/server/confluence/searching-using-the-v2-search-api/
    def paramQueryString = (queryParams.get(new String("q"))).get(0)
    def query = BooleanQuery.andQuery(new TextQuery(paramQueryString));
    def sort = new RelevanceSort();
    def searchFilter = SiteSearchPermissionsSearchFilter.getInstance();
    def searchContent = new ContentSearch(query, sort, searchFilter, 0, 100);
    def searchresult = searchManager.search(searchContent)
    return Response.ok(new JsonBuilder([results: searchresult.getAll()]).toString()).build()
}

当我调用API 时

http://10.10.10.11:8080/rest/scriptrunner/latest/custom/testSearch?q=ArticleThatWillBeDeleted

我得到以下JSON响应

            "homePage": false,
            "sanitisedContent": "this is the body of the article that will be delted."
        }
    ]
}

我得到了4倍的身体(结果摘录，结果摘录有亮点，内容，消毒内容(我所需要的只是content，如果可能的话，可以将其缩小到有限的大小或字符长度。

当我尝试通过添加以下行来实现requestedFields并修改searchresult 时

    def requestedFields = [ 'content', 'displaytitle' ] as Set
    def searchresult = searchManager.search(searchContent,requestedFields)

我得到的JSON响应是：

{
    "results": [
        {
            "resultExcerpt": "",
            "explain": {
                "present": false,
                "empty": true
            },
            "resultExcerptWithHighlights": "",
            "extraFields": {},
            "displayTitleWithHighlights": ""
        }
    ]
}

我注意到的另一件事是，在工作示例中，返回的类是：com.atlassian.confluence.search.v2.lucene.LuceneSearchResult@1233a8a4并且在CCD_ 6尝试中，结果类是：com.atlassian.confluence.search.v2.ProjectedSearchResult@6c688cdd

我想找到一种方法来控制API的输出，它不必是我试图实现的requestedFields方法。

JsonBuilder呈现所有对象属性，而不仅仅是您从服务器请求的字段。

我看到的呈现请求字段的最简单方法：

def requestedFields = [ 'content', 'displaytitle' ] as Set
def searchresult = searchManager.search(searchContent,requestedFields)
def table = searchresult.getAll().collect{row-> 
    requestedFields.collectEntries{fldName->  
        [ fldName , row.getField(fldName) ] 
    }
}
    
def json = new groovy.json.JsonBuilder(table).toPrettyString()
Response.ok(json).build()
