从 Elasticsearch 5.5.0 升级到 7.5.1 后构建错误

Question

我最近将我的应用程序中的 Elasticsearch.Net 和 NEST 从版本 5.5.0 升级到 7.5.1，但出现了一堆构建错误。我已经设法解决了其中的一些问题，但我仍然不清楚以下问题：

1) ElasticLowLevelClient.Msearch

    MultiSearchRequest multiSearchRequest = new MultiSearchRequest { Operations = operations };
    MultiSearchResponseData response = Converter.ToMultiSearchResponseData(client.Msearch<byte[]>("articles", multiSearchRequest));

其中 operations 属于 Dictionary<string, Nest.ISearchRequest> 类型，我收到以下错误：

严重性代码说明项目文件行抑制状态错误 CS1061 'ElasticLowLevelClient' 不包含 'Msearch' 的定义，并且无法找到接受类型 'ElasticLowLevelClient' 的第一个参数的可访问扩展方法 'Msearch'（您是否缺少 using 指令或汇编参考？）

2) Elasticsearch.Net.PostData

    SearchRequest request = new SearchRequest
    {
        Size = 1,
        Query = new QueryStringQuery { DefaultField = new Field("urlName"), Query = "(" + articleUrl + ")" },
    };
    ElasticsearchResponse<string> response = client.Search<string>("detailarticle", new PostData<object>(request));

我收到以下错误：

严重性代码说明项目文件行抑制状态错误 CS1729 'PostData' 不包含采用 1 个参数的构造函数

3) 批量更新操作和发布日期：

public void UpdateArticlesIndex(IEnumerable<ArticleUpdateModel> articles)
{
    if (articles == null || articles.Count() == 0)
        return;

    List<IBulkOperation> operations = new List<IBulkOperation>();
    foreach (var a in articles)
    {
        operations.Add(new BulkUpdateOperation<object, object>(a.DocumentId)
        {
            Index = "articles",
            Type = "_doc",
            Doc = a.Value,
        });
    }

    BulkRequest request = new BulkRequest
    {
        Operations = operations,
    };

    client.Bulk<string>(new PostData<object>(request));
}

我收到以下两个错误：

严重性代码说明项目文件行抑制状态错误 CS0117 'BulkUpdateOperation<object, object>' 不包含 'Type'

的定义

和

严重性代码说明项目文件行抑制状态错误 CS1729 'PostData' 不包含采用 1 个参数的构造函数

我试过修改构造函数和更改声明，但没有产生任何预期的结果。我也查看了 Elasticsearch 文档，但没有找到任何相关内容

如能提供有关解决这些构建错误的任何帮助，我们将不胜感激

Answer 1

ElasticLowLevelClient.Msearch

MultiSearchRequest multiSearchRequest = new MultiSearchRequest { Operations = operations }; MultiSearchResponseData response = Converter.ToMultiSearchResponseData(client.Msearch<byte[]>("articles", multiSearchRequest)); Where operations is of type Dictionary<string, Nest.ISearchRequest>, I am getting the following error:

Severity Code Description Project File Line Suppression State Error CS1061 'ElasticLowLevelClient' does not contain a definition for 'Msearch' and no accessible extension method 'Msearch' accepting a first argument of type 'ElasticLowLevelClient' could be found (are you missing a using directive or an assembly reference?)

使用 MultiSearch 代替 Msearch，将 MultiSearchRequest 包裹在 PostData.Serialiable 中并将响应类型从 byte[] 更改为 BytesResponse。请注意，必须从高级客户端的实例访问低级客户端，以便 MultiSearchRequest 正确序列化（ 更具体地说，应该使用 、ConnectionSettings，它配置了一个解析器，该解析器将使用正确的格式化程序 JSON 正确序列化 MultiSearchRequest)

var client = new ElasticClient();
MultiSearchRequest multiSearchRequest = new MultiSearchRequest { Operations = operations };
var response = client.LowLevel.MultiSearch<BytesResponse>("articles", PostData.Serializable(multiSearchRequest));
byte[] bytes = response.Body;

Elasticsearch.Net.PostData

SearchRequest request = new SearchRequest { Size = 1, Query = new QueryStringQuery { DefaultField = new Field("urlName"), Query = "(" + articleUrl + ")" }, }; ElasticsearchResponse response = client.Search("detailarticle", new PostData(request)); I am getting the following error:

Severity Code Description Project File Line Suppression State Error CS1729 'PostData' does not contain a constructor that takes 1 arguments

使用PostData.Serializable<T>(T data)和return一个StringResponse

var client = new ElasticClient();
var articleUrl = "example.com";

SearchRequest request = new SearchRequest
{
    Size = 1,
    Query = new QueryStringQuery { DefaultField = new Field("urlName"), Query = "(" + articleUrl + ")" },
};
var response = client.LowLevel.Search<StringResponse>("detailarticle", PostData.Serializable(request));
var str = response.Body;

I am getting the following two erros:

Severity Code Description Project File Line Suppression State Error CS0117 'BulkUpdateOperation<object, object>' does not contain a definition for 'Type'

and

Severity Code Description Project File Line Suppression State Error CS1729 'PostData' does not contain a constructor that takes 1 arguments

删除 Type，因为类型将在 Elasticsearch 中消失，并已在 NEST 7.x 中删除以用于批量请求。客户端将使用 _doc 作为 API。与2的答案类似，您应该将BulkRequest包装在PostData.Serializable<T>(T data)

中
