如何在邮递员中发送elasticsearch多重搜索请求？ [英] How to send elasticsearch multi search request in Postman?

问题描述

我正尝试通过邮递员发送弹性搜索多搜索请求，如下所示：

I'm trying to send elasticserach multi search request via postman as below:

POST - http://localhost:9200/_msearch
content-type : x-www-form-urlencoded
body:
{"index":"accounts"}
{"query":{"bool":{"should":[{"match":{"owner.first_name":"Creeple"}}]}}}

但是，我遇到以下错误：

However, I'm getting following error:

{
  "error": {
    "root_cause": [
      {
        "type": "parse_exception",
        "reason": "Failed to derive xcontent"
      }
    ],
    "type": "parse_exception",
    "reason": "Failed to derive xcontent"
  },
  "status": 400
}

请注意，如果我通过播放代码执行相同的请求，则会成功获取结果。

Note that if I perform same request via my play code, results are succesfully fetched.

WS.url("localhost:9200/_msearch").withHeaders("Content-type" -> "application/x-www-form-urlencoded").post(query)

解决方案

这里有三点很重要：

1. 插入正文时，选择 raw 单选按钮和下拉列表中的文本（或JSON）。


2. 添加标头：内容类型：application / x-ndjson


3. 最重要：在查询的最后一行后放置换行

1. When inserting body, select raw radiobutton and Text (or JSON) from dropdown.
2. Add header: Content-type: application/x-ndjson
3. Most important: put new line after the last line of your query

curl -X POST \

  -H 'cache-control: no-cache' \
  -H 'content-type: application/x-ndjson' \
  -d '{"index":"script","type":"test"}
{"query":{"match_all":{}}}
