我正在学习ElasticSearch(托管在AWS上)。 我正在使用the javascript sdkthis connectionClass

我的代码:

let es = require('elasticsearch');
let client = new es.Client({
  hosts: ['https://search-nboardelastic-xxyy.foo.es.amazonaws.com'],
  connectionClass: require('http-aws-es')
});

function handler() {
  let params = {
    index: 'product',
    q: 'bar'
  };
  client.search(params, (err, data) => {
    if (err) {
      console.log('Error ', err);
    } else {
      console.log('Data ', data);
    }
  })
}

handler();

问题: 运行代码时,出现以下错误:

Error: Request error, retrying
  POST https://https://search-nboardelasticxxyy.foo.es.amazonaws.com/product/_search => The "data" argument must be one of type string, TypedArray, or DataView

我不知道问题出在什么地方,我们将不胜感激。

我不确定四个月后此答案对您有多大帮助,但是我遇到了同样的问题,解决方案是为AWS sdk设置区域。有很多方法,我使用的方法是将aws-sdk拉入我的server.js文件并添加AWS.config.update({ region: "us-west-2" });
