如何更新索引设置，在node.js上弹性搜索中创建索引后进行映射

Question

我尝试使用node.js在弹性搜索中创建索引后尝试更新索引的设置和映射。当我尝试更新索引中的映射和设置值时，它不会更改。它仍保留在默认设置中。请建议我解决这个问题的方法。我在这里提到编码。

  fs.readFile('./article_settings.json', 'utf8', function (err, data) {
    if (err) throw err;
    settingsValue = JSON.parse(data);
    console.log("settings Json");
    console.log(settingsValue);
    return elasticClient.indices.putMapping({
            index: indexname,
            type : type_name,
            body: { "settings" : settingsValue}
    });

  });
  fs.readFile('./article_mapping.json', 'utf8', function (err, data) {
    if (err) throw err;
    mapping = JSON.parse(data);
    console.log("Mapping Json");
    console.log(mapping);
    return elasticClient.indices.putMapping({
            index: indexname,
            type : type_name,
            body: {
                  "mappings":{
                      "articles" :{
                          "properties" : mapping

                      }
                    }
            }
    });

产生错误就像。

请让我知道如何解决这个问题。谢谢。

根据评论更改代码后，它看起来像：

function initMapping(indexname,type_name){
  var fs = require('fs');
  var mapping;
  console.log(type_name);
  if(type_name == "articles"){
      fs.readFile('./article_settings.json', 'utf8', function (err, data) {
        if (err) throw err;
        settingsValue = JSON.parse(data);
        console.log("settings Json");
        console.log(settingsValue);
        elasticClient.indices.close(indexname);
        return elasticClient.indices.putSettings({
                index: indexname,
                type : type_name,
                body: { "settings" : settingsValue}
        });

      });
      elasticClient.indices.open(indexname);
      fs.readFile('./article_mapping.json', 'utf8', function (err, data) {
        if (err) throw err;
        mapping = JSON.parse(data);
        console.log("Mapping Json");
        console.log(mapping);
        return elasticClient.indices.putMapping({
                index: indexname,
                type : type_name,
                body: {
                      "mappings":{
                          "articles" :{
                              "properties" : mapping

                          }
                        }
                }
        });

      });

  }
}
