node.js - putMapping elasticsearch索引未找到异常

Question

我只是尝试使用 putMapping 创建索引，并且相当确定这是一个语法问题。弹性客户端适用于 .index 和 .search 命令，因此我认为它的设置不是问题。相反，它与我的 putmapping 代码有关。任何建议将不胜感激。关于我正在尝试做的事情的一些描述。我搜索了一个索引，发现它不存在。我捕获错误并测试它是否等于“index_not_found_exception”。如果是这样，我需要创建索引。 “...”下面的所有内容都在 .catch 内。

"use strict";
let config = require("./config"),
    soap = require("soap"),
    elastic = require("elasticsearch").Client(config.routeHost);
...
 if (error.body.error.type == "index_not_found_exception") {
        console.log("no index");
        elastic.indices.putMapping({
            index: "ppvevents",
            type: "ppvObject",
            body: {
                properties: {
                    name: {type: "string", index: "not_analyzed"},
                    hdid: {type: "integer"},
                    sdid: {type: "integer"}
                }
            }
        }).then(function(response){
            console.log("Response: ", response);
        }).catch(function(error){
            console.log("putMapping Error: ", error);
        });
    } else if(error.body.error.type != "index_not_found_exception") {
        console.log("error: elasticsearch client search");
        console.log(error);
    }

控制台响应如下:

如果索引不存在，putMapping()不会有帮助，你需要调用indices.create反而。 putMapping 只能用于向现有索引添加新映射类型。

将 putMapping 调用替换为:

    elastic.indices.createIndex({
        index: "ppvevents",
        body: {
            mappings: {
               ppvObject: {
                  properties: {
                     name: {type: "string", index: "not_analyzed"},
                     hdid: {type: "integer"},
                     sdid: {type: "integer"}
                  }
               }
            }
        }
