我目前正在使用AngularJS和SharePoint JSOM对结果源执行一些关键字查询。
我有一个接受ResultSourceName和ResultSourceLevel变量的角度工厂
angular.module('app.services.sharepoint').factory('resultSourceDataSvc', ['$log', '$q', '$timeout', function ($log, $q, $timeout) {
return function (resultSourceName, resultSourceLevel) {
return new ResultSourceDataService($log, $q, $timeout, resultSourceName, resultSourceLevel);
}
}]);
这是注入我的控制器,他们像这样使用它:
var inTheNewsResultDataSource = resultSourceData('TSToday In The News Result Source', 'SPSite');
inTheNewsResultDataSource.ready(function () {
inTheNewsResultDataSource.getData(null, IN_THE_NEWS_COLUMNS, IN_THE_NEWS_MAP_COLUMNS)
.then(function (data) {
$log.debug('Resolving data:', data);
deferred.resolve(data);
},
function (resp) {
$log.error('Error while attempting to retrieve In The News data:', resp);
deferred.reject(resp);
});
});
它的实际内容是在我工厂返回的ResultSourceDataService中处理的,这里是代码:
function ResultSourceDataService($log, $q, $timeout, resultSourceName, resultSourceLevel) {
var deferred = $q.defer(),
promise = deferred.promise,
context = undefined,
resultSourceQuery = undefined,
resultSourceExecutor = undefined,
properties = undefined;
$log = $log.getInstance('app.services.sharepoint.resultSourceDataSvc(' + resultSourceName + ')');
function init() {
$log.debug('Initializing new Result Source Data Service for:', resultSourceName, 'on', resultSourceLevel);
SP.SOD.registerSod('sp.search.js', '/_layouts/15/sp.search.js');
SP.SOD.loadMultiple(['sp.js', 'sp.search.js'], function () {
context = SP.ClientContext ? SP.ClientContext.get_current() : undefined;
// should probably add error checking to make sure context is loaded here
resultSourceQuery = new Microsoft.SharePoint.Client.Search.Query.KeywordQuery(context);
resultSourceExecutor = new Microsoft.SharePoint.Client.Search.Query.SearchExecutor(context);
resultSourceQuery.set_trimDuplicates(false);
resultSourceQuery.get_properties().set_item('SourceName', resultSourceName);
resultSourceQuery.get_properties().set_item('SourceLevel', resultSourceLevel);
$log.debug('Initialized');
deferred.resolve();
});
}
init();
//#region Private Functions
function setSelectProperties(columnsToRetrieve) {
properties = resultSourceQuery.get_selectProperties();
for (var i = columnsToRetrieve.length; i-- > 0;) {
$log.debug('Adding in property to retrieve', columnsToRetrieve[i]);
properties.add(columnsToRetrieve[i]);
}
}
function getResults(data, columnsToRetrieve, columnsToMap) {
return data.map(function (obj, i) {
var result = columnsToRetrieve.length == 0 ? obj : {};
for (var j = columnsToRetrieve.length; j-- > 0;) {
result[columnsToMap[j]] = obj[columnsToRetrieve[j]];
}
$log.debug('getResult', result);
return result;
});
}
//#endregion
//#region Public Functions
this.getData = function (keyword, columnsToRetrieve, columnsToMap) {
var deferred = $q.defer(),
promise = deferred.promise,
data = undefined,
results = [];
keyword = keyword || '*';
columnsToRetrieve = columnsToRetrieve || [];
columnsToMap = columnsToMap || columnsToRetrieve;
resultSourceQuery.set_queryText(keyword);
setSelectProperties(columnsToRetrieve);
$log.info('Attempting to retrieve data from result source with keyword:', keyword, resultSourceQuery);
data = resultSourceExecutor.executeQuery(resultSourceQuery);
context.executeQueryAsync(
function (sender, args) {
$log.debug('Data retrieved successfully', data.get_value().ResultTables);
results = getResults(data.get_value().ResultTables[0].ResultRows, columnsToRetrieve, columnsToMap);
$log.info('Resolving data', results);
deferred.resolve(results);
},
function (sender, args) {
$log.error('Error with resolving data in ResultSourceDataService', args.get_message());
deferred.reject(args.get_message());
});
return promise;
}
this.ready = function (fn) {
promise.then(fn);
}
//#endregion
}
当我加载运行此代码的页面时,它运行正常。当我刷新页面时,它运行正常。但是,如果我从我的网站中的任何其他页面导航到此页面,它会中断并返回数据,就像没有指定结果源一样。
出于某种原因,QueryModification(如果我是正确的,基本上告诉它我们在查询中寻找的ContentType)正在发生变化。当我最初加载页面并查看记录到控制台的数据($log.debug('Data retrieved successfully', data.get_value().ResultTables);
)时,我可以深入查看它并查看QueryModification中的差异。
如果它正常运行(刷新页面或直接从站点外部导航到该页面),我会看到ContentTypeId:0x0100A9723709C6D74A77B01EA922C770FDD0*
的值,这是正确的。然而;如果我从SharePoint内部导航到该页面,我会看到* -ContentClass=urn:content-class:SPSPeople
的值,如果我没有指定结果源名称,它会返回结果。
当我将相同的确切变量传递给它时,有什么可能导致这种情况的想法?
答案 0 :(得分:0)
不知道为什么会这样,但删除了
resultSourceQuery.get_properties().set_item('SourceName', resultSourceName);
resultSourceQuery.get_properties().set_item('SourceLevel', resultSourceLevel);
来自init
方法的并将其添加到getData
方法修复了该问题。不知道为什么它会起作用,因为如果调用代码使用getData
方法,那么应始终在ready
方法之前设置它。
如果有人知道为什么修复它,请指出它。与此同时,我的问题已经解决。
