如何解决如何减少Java / groovy中的自定义API端点的输出
我正在努力改善对我们的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Search API端点，它目前可以正常工作，但是返回很多不必要的信息，甚至返回重复信息，因此我想以最有效的方式缩小搜索范围。
该平台具有我要用于实现的javadoc，链接：https://docs.atlassian.com/ConfluenceServer/javadoc/7.8.1/com/atlassian/confluence/search/v2/SearchManager.html
我要实现以下部分
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.
但是我不明白如何正确生成Set<String> requestedFields。
这是我的尝试：
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,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.
脚本运行正常，但是返回了很多我想删除的信息。
除了要实现的方法外，我还接受其他任何类型的建议，在这些建议中，我可以仅指定要输出的信息，以便可以安全地输出大小和处理能力。
P.S。 我已经尝试在他们的社区页面上详细询问相同的问题，但是由于我刚刚从Java / Groovy的工作中学到了知识，因此我可以在此方面使用一些开发人员帮助。
更新：
以下是作为API端点实现的工作代码：
import com.atlassian.seraph.auth.DefaultAuthenticator
import com.atlassian.confluence.user.UserAccessor
import com.atlassian.confluence.user.AuthenticatedUserThreadLocal
import com.atlassian.confluence.spaces.SpaceManager
import com.atlassian.sal.api.component.ComponentLocator
import com.atlassian.confluence.search.service.ContentTypeEnum
import com.atlassian.confluence.search.v2.SearchManager
import com.atlassian.confluence.search.v2.searchfilter.SiteSearchPermissionsSearchFilter
import com.atlassian.confluence.search.v2.ContentSearch
import com.atlassian.confluence.search.v2.query.*
import com.atlassian.confluence.search.v2.sort.RelevanceSort
import com.atlassian.confluence.search.v2.SearchSort
import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.json.JsonBuilder
import groovy.transform.BaseScript
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
import org.codehaus.jackson.map.ObjectMapper
import java.util.HashSet
@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,100);
def searchresult = searchManager.search(searchContent)
return Response.ok(new JsonBuilder([results: searchresult.getAll()]).toString()).build()
}
当我调用API
http://10.10.10.11:8080/rest/scriptrunner/latest/custom/testSearch?q=ArticleThatwillbedeleted
我收到以下JSON响应
{
"results": [
{
"displayTitle": "ArticleThatwillbedeleted","handle": {
"className": "com.atlassian.confluence.pages.Page","id": 359071873
},"lastUpdateDescription": "","ownerTitle": null,"spaceName": "Employee Team Space","creatorUser": {
"backingUser": {
"active": true,"lowerName": "vnikolov","directoryId": 142049281,"fullName": "Vasil Nikolov","emailAddress": "vnikolov@domain.com","email": "vnikolov@domain.com","name": "vnikolov","displayName": "Vasil Nikolov"
},"key": {
"stringValue": "8a606c8c56a371040156a37301341285"
},"name": "vnikolov"
},"resultExcerpt": "this is the body of the article that will be delted.","ownerType": null,"lastModifier": "vnikolov","urlPath": "/display/WIT/ArticleThatwillbedeleted","resultExcerptWithHighlights": "this is the body of the article that will be delted.","explain": {
"present": false,"empty": true
},"lastModifierUser": {
"backingUser": {
"active": true,"extraFields": {
"content-version": "1"
},"lastModificationDate": "2020-10-20T20:42:27+0000","type": "page","content": " \nthis is the body of the article that will be delted.\n ","creationDate": "2020-10-20T20:41:46+0000","personalLabels": [],"status": "current","spaceKey": "WIT","contentVersion": 1,"creator": "vnikolov","displayTitleWithHighlights": "ArticleThatwillbedeleted","homePage": false,"sanitisedContent": "this is the body of the article that will be delted."
}
]
}
我得到4倍的身体（resultExcerpt，resultExcerptWithHighlights，content，sanitisedContent）
我所需要的只是content，并尽可能将其切成一定的大小或字符长度。
searchresult时
def requestedFields = [ 'content','displaytitle' ] as Set
def searchresult = searchManager.search(searchContent,requestedFields)
我得到的JSON响应是：
{
"results": [
{
"resultExcerpt": "","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
并在requestedFields尝试中，结果类为：
com.atlassian.confluence.search.v2.ProjectedSearchResult@6c688cdd
我想找到一种方法来控制API的输出，不必一定是我要实现的requestedFields方法。
解决方法
JsonBuilder呈现所有对象属性，而不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()
