node.js elasticsearch API 查询搜索请求发送 POST 方法而不是 GET

Question

我正在为 node.js 使用 elasticsearch API 来对 aws elasticsearch 进行 following 查询。

elasticsearch documentation说请求体搜索使用GET方式

我正在使用 wireshark 查看我的应用程序通过正文搜索方法发送的请求，我发现使用的方法是 POST.

为什么要发送 POST？我只想允许对我的域的 GET 请求。

elasticsearch.js

var elasticsearch = require('elasticsearch');

var AWS = require('aws-sdk');
AWS.config.update({ region: 'eu-central-1' });

var elasticClient = elasticsearch.Client({
  hosts: [ 'host' ],
  connectionClass: require('http-aws-es'),
  log: ['error', 'warning'],
    amazonES: {
        region: 'eu-central-1',
        accessKey: 'accessKey',
        secretKey: 'secretKey'
    }
 });

var indexName = "indexName";

var type = "records";
    function querySearch(data){
        console.log("[INFO]: Check data "+JSON.stringify(data));
        return elasticClient.search({
            index: indexName,
            type: type,
            body:  data
        });

    }

    exports.querySearch = querySearch;

index.js

var elastic = require('./elasticsearch.js');
    elastic.querySearch({"query": {"bool": {"must": [{ "match": { "id": "value" } }]}}}).then(function (resp) {
        //If data doesn't exist in elasticsearch insert into Firehose
        if (resp.hits.hits.length == 0){
            console.log("[INFO]: No data");
        }else{
            console.log("[INFO]: Record already in Elasticsearch");
        }
    }, function (err) {
        console.trace("[ERROR]: "+err.message);
    });

当我浏览 elasticsearch 模块并发现在 search 中使用 POST.

pi.search = ca({
  params: {
    includeTypeName: {
      type: 'string',
      name: 'include_type_name'
    },
    ......
    method: 'POST'
});
