使用Elasticsearch的Ajax查询格式 [英] Ajax query format with Elasticsearch

问题描述

我正在尝试使用AJAX向我的elasticsearch索引发出发布请求. cURL结果为:

I am trying to make a post request with AJAX to my elasticsearch index. The cURL result is:

[~]$ curl -XGET 'http://localhost:9200/firebase/_search?q=song:i%20am%20in'

{"took":172,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2,"max_score":0.82749283,"hits":[{"_index":"firebase","_type":"song","_id":"0001","_score":0.82749283,"_source":{"song":"i am in california","song_name":"hello","song_url":"https://s3.ap-south-1.amazonaws.com/songapp-dump/media/songs/Adele_-_Hello-_i_am_in_california.mp3"}},{"_index":"firebase","_type":"song","_id":"0002","_score":0.28582606,"_source":{"song":"i must have called a thousand times","song_name":"hello","song_url":"https://s3.ap-south-1.amazonaws.com/songapp-dump/media/songs/Adele_-_Hello-_i_must_have_called_a_thousand_times.mp3"}}]}} 

浏览器结果为:这也可以正常工作.意味着已经创建了索引，并且cURL/GET可以获取结果.

Browser result is:This is also working correctly. Meaning the index has been created and cURL/ GET is able to get the result.

当我尝试执行AJAX请求时，我可能会在查询格式方面苦苦挣扎.我不知道.

When I am trying to have an AJAX request do the same, I am struggling with the query format probably. I am not able to figure out.

Ajax.js

$(function() {
    $('#message').keyup(function() {
        // console.log(JSON.stringify());
        var data = {
                'song': $('#message').val()
            };
        console.log(JSON.stringify(data));
        $.ajax({
            type: "POST",
            url: "http://localhost:9200/firebase/_search",
            contentType: 'application/json',
            // data: {
            //     'q': $('#message').val()
            // },
            data: JSON.stringify(data),
            success: searchSuccess,
            dataType: 'jsonp'
        });

    });

});

控制台记录以下错误:

The console logs the following error:

基本上是400错误的请求错误.我无法弄清楚我的查询或创建Ajax请求的方式是否有问题.为什么会有回调问题！任何帮助，将不胜感激.我已经在网上搜索了此问题，并尝试了各种组合.

Basically it's a 400 Bad Request error. I am not able to figure out if there is something wrong with my query or the way Ajax request is being created. Why am I having callback issues! Any help would be appreciated. I have scoured the web on this issue and have tried various combinations as well.

推荐答案

将方法更改为GET，将dateType更改为json.此外，querystring还需要一个q参数.

Change the method to GET and dateType to json. Also the querystring requires a q parameter.

     var data = {
         'q': 'song:' + $('#message').val()
     };

     $.ajax({
        type: "GET",
        url: "http://localhost:9200/firebase/_search",
        contentType: 'application/json',
        data: JSON.stringify(data),
        success: searchSuccess,
        dataType: 'json'
    });
