C# ElasticSearch嵌套-所有字段均为空
我正在尝试使用NEST从弹性搜索中检索数据。一切都很好,但嵌套所有字段都返回null。但是,在调试模式下,我看到它正确地计算了文档的数量,但没有显示字段的值 我已经做了:C# ElasticSearch嵌套-所有字段均为空,c#,

elasticsearch,Nest,我正在尝试使用NEST从弹性搜索中检索数据。一切都很好,但嵌套所有字段都返回null。但是,在调试模式下,我看到它正确地计算了文档的数量,但没有显示字段的值 我已经做了: 检查了地图,我觉得还不错 尝试字符串查询 试图获取源,然后读取数据 尝试 这些解决方案也无济于事 将Product.cs字段名称重命名为camelCase也没有帮助 这是我的密码 public class ElasticSearch { private ElasticClient _client; p
- 检查了地图,我觉得还不错
- 尝试字符串查询
- 试图获取源,然后读取数据
- 尝试 这些解决方案也无济于事
- 将Product.cs字段名称重命名为camelCase也没有帮助
public class ElasticSearch
{
private ElasticClient _client;
public ElasticSearch()
{
var node = new Uri("http://localhost:9200");
var settings = new ConnectionSettings(node);
settings.DefaultIndex("logsystem.logs");
_client = new ElasticClient(settings);
}
public void searchResults()
{
var searchResults = _client.Search<Product>(s => s.AllIndices());
}
}
ElasticSearch中的映射:
{
"logsystem.logs": {
"mappings": {
"properties": {
"Action": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"ActionName": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"MachineId": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"Name": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"ProductLicenseKey": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
也许我的映射不对?任何答案都会有帮助。谢谢

所以问题在于,客户机试图将camelCased JSON对象键反序列化到POCO属性,并且强制转换非常严格 解决方案: 创建ES客户端时,在连接设置上添加设置属性DefaultFieldNameInferrer
public ElasticSearch()
{
var node = new Uri("http://localhost:9200");
var settings = new ConnectionSettings(node);
settings.DefaultIndex("logsystem.logs");
settings.DefaultFieldNameInferrer(p => p);
_client = new ElasticClient(settings);
}
“你能发布弹性搜索中记录的样子吗?”VireshMathad在帖子中补充道。这就是我从PostmanI那里得到的,我想你应该检查“点击”而不是文档。@VireshMathad nahh same。。甚至找不到的字段。。。
public ElasticSearch()
{
var node = new Uri("http://localhost:9200");
var settings = new ConnectionSettings(node);
settings.DefaultIndex("logsystem.logs");
settings.DefaultFieldNameInferrer(p => p);
_client = new ElasticClient(settings);
}
