c# - 使用Vulcan Elasticsearch EPiServer映射错误

Question

是否有人使用过名为Vulcan的EPiServer的elasticsearch客户端？ (https://github.com/TCB-Internet-Solutions/vulcan)

通过所有帐户(包括写得很好的一个帐户:https://blog.wsol.com/getting-started-using-vulcan-search-in-episerver)，它应该像从EPiServer NuGet feed中安装NuGet包“TcbInternetSolutions.Vulcan.Core”，添加web.config设置并运行计划作业一样简单。索引数据。

我在我的EPiServer项目(版本11.2.1)中安装了NuGet软件包(版本3.0.1)，并设置了web.config设置，索引作业报告“作业已完成。请刷新页面以查看状态。”运行历史记录显示“Vulcan已成功在1个索引器中索引了100个项目!”。

但是，当我查看“\ App_Data \ EPiServerErrors.log”文件时，看到大量错误，例如:

ERROR TcbInternetSolutions.Vulcan.Core.Implementation.VulcanClient: Vulcan could not index content with content link 10 for language en: System.Exception: Invalid NEST response built from a unsuccessful low level call on PUT: /customername_en/EPiServer.Core.BlockData/10 Audit trail of this API call: - [1] BadResponse: Node: http://localhost:9200/ Took: 00:00:00.4026489 ServerError: ServerError: 400Type: mapper_parsing_exception Reason: "failed to find type parsed [string] for [contentAssetsID]" OriginalException: System.Net.WebException: The remote server returned an error: (400) Bad Request. at System.Net.HttpWebRequest.GetResponse() at Elasticsearch.Net.HttpConnection.Request[TReturn](RequestData requestData) in C:\Projects\elastic\net-2\src\Elasticsearch.Net\Connection\HttpConnection.cs:line 163

似乎由于在“[contentAssetsID]”为数字的情况下所有内容到字符串的默认映射，因此无法在索引“customername_en”中为类型“EPiServer.Core.BlockData”建立索引。因此，我尝试添加一个初始化类以将映射设置为AutoMap:

[ModuleDependency(typeof(ServiceContainerInitialization))]
public class SearchInitialization : IConfigurableModule
{
    public void ConfigureContainer(ServiceConfigurationContext context)
    {
        // Nothing to do
    }

    public void Initialize(InitializationEngine context)
    {
        var vh = ServiceLocator.Current.GetInstance<VulcanHandler>();
        var vhClient = vh.GetClient(new System.Globalization.CultureInfo("en"));
        var res = vhClient.Map<EPiServer.Core.BlockData>(m => m.AutoMap());
    }

    public void Uninitialize(InitializationEngine context)
    {
        // Nothing to do
    }
}

“res”返回成功的响应，但错误仍然发生。

请帮忙!

感谢Dimitar，我使用的是ElasticSearch 5而不是2。更改为版本2后，它可以工作了。
