当尝试使用 Azuren 搜索和 Azure Table 存储覆盖分区键时，.NET 收到错误请求

Question

我正在使用 Azuren Search 和 Azure Table Storage 以及 .net，我正在尝试索引一个 table 并使分区键现在可以过滤，这在我尝试插入一些东西之前工作正常在那个 table 中，我收到一个没有太多附加信息的 BadRequest。这是我的 class 波纹管

using System;
using Microsoft.Azure.Search;
using Microsoft.Azure.Search.Models;
using Microsoft.WindowsAzure.Storage.Table;

      [SerializePropertyNamesAsCamelCase]
    public class Asset : TableEntity
    {
        public Asset(string name)
        {
            Name = name;
        }

        public Asset()
        {

        }

        public Asset(string name, DateTimeOffset toBePublished, string pkey)
        {
            Name = name;
            ToBePublishedDate = toBePublished;
            PartitionKey = pkey;
        }

        [System.ComponentModel.DataAnnotations.Key]
        public string Id { get; set; } = DateTimeOffset.UtcNow.ToString("O")
            .Replace("+", string.Empty)
            .Replace(":", string.Empty)
            .Replace(".", string.Empty);

        [IsFilterable, IsSortable, IsSearchable]
        public new string PartitionKey { get; set; }

        [IsFilterable, IsSortable, IsSearchable]
        public string Name { get; set; } = "TemptAsset " + new Guid();

        [IsFilterable, IsSortable]
        public int? Version { get; set; } = 1;

        [IsFilterable, IsSortable]
        public DateTimeOffset? ToBePublishedDate { get; set; } = DateTimeOffset.UtcNow;

        [IsFilterable, IsSortable]
        public DateTimeOffset? ToBeRetiredDate { get; set; } = null;

        [IsFilterable, IsSearchable, IsSortable]
        public string Company { get; set; } = "TempCompany";
        [IsFilterable, IsSortable]
        public bool IsApproved { get; set; } = false;

        [IsFilterable, IsSortable]
        public bool IsDraft { get; set; } = true;


    }

这运行s 并且索引创建成功见下文

现在，如果我尝试向该 table 添加一个实体，我会得到一个 BadRequest，但是通过在我的实体中注释掉 PartitionKey 来做完全相同的事情，这工作正常。这就是我创建索引的方式

AzureSearch.CreateAssetNameIndex(AzureSearch.CreateSearchServiceClient());

    and the methods called bellow




using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Threading;
    using System.Threading.Tasks;
    using AssetSynch.Models;
    using Microsoft.Azure.Search;
    using Microsoft.Azure.Search.Models;
      public static SearchServiceClient CreateSearchServiceClient()
        {
            string searchServiceName = "*****";
            string adminApiKey = "********";

            SearchServiceClient serviceClient = new SearchServiceClient(searchServiceName,
                new SearchCredentials(adminApiKey));

            return serviceClient;
        }

    public static async void CreateAssetNameIndex(SearchServiceClient serviceClient)
        {
            Index definition = new Index
            {
                Name = "assetname",
                Fields = FieldBuilder.BuildForType<Asset>()
            };

            await serviceClient.Indexes.CreateAsync(definition);
        }

如果我 return 使用邮递员时出现错误，这是我得到的异常

      {
  "innerExceptions": [
    {
      "requestInformation": {
        "httpStatusCode": 400,
        "httpStatusMessage": "Bad Request",
        "serviceRequestID": "59efbc9a-0002-002c-3570-d5d55c000000",
        "contentMd5": null,
        "etag": null,
        "requestDate": "Thu, 25 May 2017 17:05:01 GMT",
        "targetLocation": 0,
        "extendedErrorInformation": {
          "errorCode": "PropertiesNeedValue",
          "errorMessage": "The values are not specified for all properties in the entity.\nRequestId:59efbc9a-0002-002c-3570-d5d55c000000\nTime:2017-05-25T16:05:06.5197909Z",
          "additionalDetails": {}
        },
        "isRequestServerEncrypted": false
      }
    }
  ]
}

如果我从我的实体中删除分区键并重新运行相同的代码以重新创建索引，则相同的代码段将成功执行。我注意到的是，我的实体上现在有 2 个分区键，其中一个将保持为空，请参见下图，并且我的属性不会覆盖原始的。

这里有什么我遗漏的吗？

根据你的代码，我发现你的资产使用了new关键字来修改基础class的分区属性。

但这只会隐藏 base.partition 而不会覆盖它。

public new string PartitionKey { get; set; }

在Asset class中设置值后，您会发现它包含如下两个分区：

所以如果基class的分区键值为空，就会return 400错误。

因此，如果您想将新实体添加到 table，您需要设置基础 class(TableEntity) 分区键值。

所以我建议您可以如下更改您的资产：

  [SerializePropertyNamesAsCamelCase]
    public class Asset : TableEntity
    {
        public Asset(string name)
        {
            Name = name;
            base.PartitionKey = this.PartitionKey;
        }

        public Asset()
        {
            base.PartitionKey = this.PartitionKey;
        }

        public Asset(string name, DateTimeOffset toBePublished, string pkey)
        {

            Name = name;
            ToBePublishedDate = toBePublished;         
            PartitionKey = pkey;
            base.PartitionKey = this.PartitionKey;
        }

        [Key]
        [IsFilterable]
        public string Id { get; set; } = DateTimeOffset.UtcNow.ToString("O")
            .Replace("+", string.Empty)
            .Replace(":", string.Empty)
            .Replace(".", string.Empty);

        [IsFilterable, IsSortable, IsSearchable]
        public new string PartitionKey { get; set; }

        [IsFilterable, IsSortable, IsSearchable]
        public string Name { get; set; } = "TemptAsset " + new Guid();

        [IsFilterable, IsSortable]
        public int? Version { get; set; } = 1;

        [IsFilterable, IsSortable]
        public DateTimeOffset? ToBePublishedDate { get; set; } = DateTimeOffset.UtcNow;

        [IsFilterable, IsSortable]
        public DateTimeOffset? ToBeRetiredDate { get; set; } = null;

        [IsFilterable, IsSearchable, IsSortable]
        public string Company { get; set; } = "TempCompany";
        [IsFilterable, IsSortable]
        public bool IsApproved { get; set; } = false;

        [IsFilterable, IsSortable]
        public bool IsDraft { get; set; } = true;


    }

如果你想使用table存储作为数据源，我建议你可以参考这个article。
