Tridion 2009 SP1代理未返回结果
我很难根据一个相当简单的查询从代理加载动态组件演示文稿,如下所示,我试图根据使用特定关键字标记的情况加载组件:Tridion 2009 SP1代理未返回结果,tridion,tridion2009,tridion-content-delivery,Tridion,Tridion2009,Tridion Content Delivery,我很难根据一个相当简单的查询从代理加载动态组件演示文稿,如下所示,我试图根据使用特定关键字标记的情况加载组件: private string GetComponentPresentations() { Logger.Log.Info("Entered GetComponentPresentations"); var publicationCriteria = new PublicationCriteria(_publicationId);
private string GetComponentPresentations()
{
Logger.Log.Info("Entered GetComponentPresentations");
var publicationCriteria = new PublicationCriteria(_publicationId);
int schemaId = int.Parse(SchemaId.Split('-')[1]);
// Is it the correct content type (Schema)
var isSpecifedSchema = new ItemSchemaCriteria(schemaId);
// Type of the item is 16 (Component).
var isComponent = new ItemTypeCriteria(16);
// All of the above conditions must be true
Criteria isCorrectComponent = CriteriaFactory.And(isSpecifedSchema, isComponent);
var publicationAndIsComponent = CriteriaFactory.And(publicationCriteria, isCorrectComponent);
//Only get components tagged with the specified keyword
var keywordCriteria = new KeywordCriteria(_productsCategoryTcmId, ProductFilter, Criteria.Equal);
//Only get Components of the correct type from the correct publication
Criteria fullCriteria = CriteriaFactory.And(publicationAndIsComponent, keywordCriteria);
using (var query = new Query(fullCriteria))
{
string[] results = query.ExecuteQuery();
using (var cpf = new ComponentPresentationFactory(_publicationId))
{
if(results != null)
{
var resultString = new StringBuilder();
foreach (string componentTcmId in results)

Logger.Log.Info("Looping over results");

我可以在代理数据库的ITEMS\u CATEGORIES\u和\u KEYWORDS表中看到带有我期望的关键字的项目,如果我注释掉查询并硬编码TCM ID,我可以手动加载CP
我已确保该类别已发布,并且所有变量的值都是正确的
我已经确保关键字有一个值和一个设置为适当值的键
我还可以检查什么?您是否尝试过在查询中使用SetCriteria方法?例如:
query.SetCriteria(multipleCombinedFacetCriteria);
String[] itemURIS = query.ExecuteQuery();
在查看Java API时,我可以看到以下重载:
KeywordCriteria(java.lang.String categoryName, java.lang.String keyword, FieldOperator operator)
_productsCategoryTcmId是否只需要作为类别的名称而不是URI?我建议逐个从查询中删除每个条件,并检查每个条件返回的结果
另一件需要检查的事情是,您正在使用您认为正确的API。Tridion有两个非常相似的代理查询API。仔细检查您是否链接到了正确的程序集。我已使用以下代码成功完成此操作:
private string GetComponentPresentationsUsingFilter()
{
//RSL: Had to use the obsolete filtering API because could not get anything back from the Broker.
var filter = new SearchFilter("tcm:0-" + _publicationId + "-1");
var query = new Query();
string schemaId = SchemaId.Split('-')[1];
query.AddCriteria("schema", "=", schemaId);
query.AddCustomMetaQuery(string.Format("KEY_NAME = 'product' AND CAST(KEY_STRING_VALUE as nvarchar(100)) = '{0}'", ProductFilter));
string[] results = filter.Match(query, new Sorting("title=asc"), MaxItems);
if (results == null)
{
Logger.Log.Info("Results was null.");
return string.Empty;
}
using (var cpf = new ComponentPresentationFactory(_publicationId))
{
var resultString = new StringBuilder();
Logger.Log.InfoFormat("Got {0} Results", results.Length);
foreach (string componentTcmId in results)
{
int componentId = int.Parse(componentTcmId.Split('-')[1]);
Logger.Log.InfoFormat("Got componentId as {0}", componentId);
int templateId = int.Parse(TemplateId.Split('-')[1]);
Logger.Log.InfoFormat("Got templateId as {0}", templateId);
ComponentPresentation cp = cpf.GetComponentPresentation(componentId, templateId);
if (cp != null && !string.IsNullOrEmpty(cp.Content))
{
resultString.Append(cp.Content);
Logger.Log.InfoFormat("Appended Content {0}", cp.Content);
}
}
return resultString.ToString();
}
}
不知道为什么我可以通过这种方式获得结果,但使用Criteria api却无法获得结果?您是否检查过您正在查询的类别是否已发布?如果使用较新的“标准”机制,则需要执行此操作。我总是喜欢那个
谢谢你,乔纳森,我也很想知道这一点,但是没有用。在与技术总监进行了一些测试和SQL评测之后,我们发现代码没有进入数据库。我不得不使用过时的过滤器API来获得任何结果。您是否从旧版本的Tridion迁移过来?也许lib目录中仍然有一些旧的Jar文件?不,这是一个新安装的2009 SP1,带有内容交付累积修补程序appliedCan您可以根据schema_ID获得代理项目,或者其他一些基本的东西吗?那么,当你删除taxonomyFilterI时会发生什么呢?我尝试了这个,发现我根本没有访问数据库。我认为我引用了错误的DLL,但无法确定哪些是正确的。。我已经让它与过时的过滤API一起工作,但我并不高兴。
