ElasticSearch client.indices.putMapping总是失败 [英] ElasticSearch client.indices.putMapping always fail

问题描述

我真的不了解文档.即使在阅读了一些SO问题和答案之后(例如:这一个).我有这个代码

I really don't understand the docs. Even after reading a few SO questions and answers (ex: this one). I have this code

let indexMapping = {
  'foo': {
    name: { type: 'string', index: 'analyzed' },
    value: { index: 'no' },
    dynamic_templates: [ {
      customRule: {
        path_match: 'bar.*',
        mapping: { type: '{dynamic_type}', index: 'no' }
      }
    } ]
  }
};
let indexName = 'foos';
let typeName = 'foo';

client.indices.putMapping({
  index: indexName,
  type: typeName,
  [typeName]: {
    properties: indexMapping[typeName]
  }
}).catch(function (err) {
  console.error(err.stack || err);
});

我总是得到

错误:[action_request_validation_exception]验证失败:1:映射源为空；

Error: [action_request_validation_exception] Validation Failed: 1: mapping source is empty;

我在做什么错了?

我的索引是新创建的，没有添加文档或当前定义的任何类型.这是我要在添加文档和建立索引之前将映射设置为新的空白索引.

My index is newly created, and there are no documents added or any types currently defined. This is a new, blank, index that I want to set mappings to before adding and indexing documents.

推荐答案

动态模板声明应与映射类型的 properties 处于同一级别，因此您的代码应如下所示:

Dynamic templates declarations should go at the same level as the properties of a mapping type, so your code should look like this instead:

let indexName = 'foos';
let typeName = 'foo';

let indexMapping = {
  'properties': {
    [typeName]: {
      name: { type: 'string', index: 'analyzed' },
      value: { type: 'string', index: 'no' }
    }
  },
  'dynamic_templates': [ {
      customRule: {
          path_match: 'bar.*',
          mapping: { type: '{dynamic_type}', index: 'no' }
      }
  } ]
};

client.indices.putMapping({
  index: indexName,
  type: typeName,
  body: indexMapping
}).catch(function (err) {
  console.error(err.stack || err);
});
