我正在尝试以编程方式发布媒体项目,但我遇到了 PublishOptions 对象的问题。在运行时,当我上传媒体项目时,正在实例化 PublishOptions 对象的代码行会中断。我收到以下消息:
"Value cannot be null. Parameter Name: item"
堆栈跟踪是:
at Sitecore.Diagnostics.Assert.ArgumentNotNull(Object argument, String argumentName)
at Sitecore.Data.Managers.ItemProvider.ApplySecurity(Item item, SecurityCheck securityCheck)
at Sitecore.Data.Managers.ItemProvider.GetRootItem(Language language, Version version, Database database, SecurityCheck securityCheck)
at Sitecore.Data.Managers.ItemManager.GetRootItem(Language language, Version version, Database database)

at Sitecore.Data.Managers.ItemProvider.ResolvePath(String itemPath, Database database)
at Sitecore.Data.Managers.ItemProvider.GetItem(String itemPath, Language language, Version version, Database database, SecurityCheck
这是正在实例化 PublishOptions 对象的代码(它正在中断):
public void OnItemSaved(Object sender, EventArgs args)
{
var item = Event.ExtractParameter(args, 0) as Item;
using (new SecurityDisabler())
{
if (item != null)
{
if (item.Paths.IsMediaItem)
{
var source = new Database("master");
var target = new Database("web");
var options = new PublishOptions(source, target, PublishMode.SingleItem, item.Language, DateTime.Now)
{
RootItem = item,
Deep = true,
};
var publisher = new Publisher(options);
publisher.PublishAsync();
}
}
}
}
我收到此错误的原因可能是什么?
最佳答案
试试这个,看看这是否有效,我猜它与数据库有关。
public void OnItemSaved(Object sender, EventArgs args)
{
var item = Event.ExtractParameter(args, 0) as Item;
using (new SecurityDisabler())
{
if (item != null)
{
if (item.Paths.IsMediaItem)
{
var source = Factory.GetDatabase("master");
var target = Factory.GetDatabase("web");
var options = new PublishOptions(source, target,
PublishMode.SingleItem, item.Language,
DateTime.Now)
{
RootItem = item,
Deep = true,
};
var publisher = new Publisher(options);
publisher.PublishAsync();
}
}
}
}
关于c# - 尝试以编程方式发布媒体项目时,PublishOptions 失败,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19958800/
