SitecoreIdMapper 不支持Coveo.UI.Components.Models.IBaseComponentProperties.Id

Question

我刚刚接触与 Sitecore 集成的 Coveo 搜索。我发生了一个奇怪的异常，我无法弄清楚为什么会发生这种情况。当导航到带有 Coveo 组件的搜索页面时。我看到这个异常。

**The type Coveo.UI.Components.Models.IBaseComponentProperties on Coveo.UI.Components.Models.IBaseComponentProperties.Id is not supported by SitecoreIdMapper
Description: An unhandled exception occurred.**

当我查看 DLL 时，我看到 IBaseComponentProperties.cs 看起来像这样

namespace Coveo.UI.Components.Models
{
  public interface IBaseComponentProperties
  {
    string Id { get; }

    string CssClass { get; }

    string PlaceholderId { get; }

    string ItemId { get; }

    bool HasDataSource { get; }
  }
}

此 ID 是 string

类型

当我查看 SitecoreIdMapper.cs 时，我看到了这个：

namespace Glass.Mapper.Sc.DataMappers
{
  public class SitecoreIdMapper : AbstractDataMapper
  {
    private Func<Item, object> _getValue;

    public SitecoreIdMapper() => this.ReadOnly = true;

    public override void MapToCms(AbstractDataMappingContext mappingContext) => throw new NotImplementedException();

    public override object MapToProperty(AbstractDataMappingContext mappingContext) => this._getValue(((SitecoreDataMappingContext) mappingContext).Item);

    public override void Setup(DataMapperResolverArgs args)
    {
      if (args.PropertyConfiguration.PropertyInfo.PropertyType == typeof (Guid))
        this._getValue = (Func<Item, object>) (item => (object) item.ID.Guid);
      else if (args.PropertyConfiguration.PropertyInfo.PropertyType == typeof (ID))
        this._getValue = (Func<Item, object>) (item => (object) item.ID);
      else
        throw new NotSupportedException("The type {0} on {0}.{1} is not supported by SitecoreIdMapper".Formatted((object) args.PropertyConfiguration.PropertyInfo.ReflectedType.FullName, (object) args.PropertyConfiguration.PropertyInfo.Name));
      base.Setup(args);
    }

    public override bool CanHandle(AbstractPropertyConfiguration configuration, Context context) => configuration is SitecoreIdConfiguration;
  }
}

因此，SitecoreIdMapper 似乎需要 PropertyType 的 GUID 或 ID，并且由于它是一个字符串，因此它落入 else 子句中，在该子句中引发了不支持的异常..

由于 Coveo for Sitecore 和 GlassMapper for Sitecore 是模块，并且应该是可配置的。我确定必须有一些我可以配置的东西来纠正这个问题？这些都是非常常见的模块，这难道是以前见过的吗？！

有人能指出我正确的方向吗？

Answer 1

经过一段时间的项目研究。我发现一些自定义代码只是将 Coveo IBaseComponentProperty 对象直接传递到玻璃映射器中。所以答案就是要确定GUID的类型。获取 IBaseComponentProperty 的字符串并使用字符串数据更新 GUID。因为 coveo 会将 GUID 存储在该字符串中。

新的 Guid(CoveoObj.Id);

不幸的是，这些模型之间的切换发生的位置因项目而异。所以你需要解决这个部分。但他的答案是确保该字符串被解析为 GUID。否则，当 GlassMapper 的反射查找失败时，将触发 NotSupportedExpection。
