将查询发布到Golang中的Splunk REST API / search / jobs /端点

Question

I would like to send a search/query to Splunk REST API, and return a search id to later consume the results.

I can achieve the desired behavior with the below curl:

#!/bin/bash

user='my_user'
pass='my_pass'

search='search index=short sourcetype=src | head 5'

curl -u $user:$pass -k https://111.22.33.44:8089/services/search/jobs -d search="$search"

which returns:

<?xml version="1.0" encoding="UTF-8"?>
<response>
  <sid>234523452435.6556_234234-3J3J-34J4-2345-123456678E3</sid>
</response>

Here are the relevant Go snippets in which I am trying to achieve the same:

Main:

  //main.go
    sid, err := conn.Query()
    if err != nil {
            fmt.Println("err creating search: %s", err)
    } else {
            fmt.Println("sid:", sid)
    }

Query:

    // query.go
    func (conn SplunkConnection) Query() (string, error) {
            data := make(url.Values)
            data.Add("output_mode", "json")
            data.Add("search%20index%3Dshort%20sourcetype%3Dsrc%20%7C%20head%205", "search")
            data.Add("-60m%40m", "earliest")
            data.Add("-10m%40m", "latest")

        // try httpGet() here
        sid, err := conn.httpPost(fmt.Sprintf("%s/services/search/jobs", conn.BaseURL), &data)
        if err != nil {
                return "", err
        }

        return string(sid), err
}

Helper:

// http.go
func (conn SplunkConnection) httpPost(url string, data *url.Values) (string, error) {
        return conn.httpCall(url, "POST", data)
}

What I expect is a response containing just a JSON blob with my SID. Instead, it returns a huge JSON, which appears to be contain all current jobs at the /services/search/jobs endpoint.

How can I adjust my code to return just the SID? (I intend to poll it for completion and retrieve the results later, but don't need help with this...yet).

You seem to have reversed your postdata parameters.

            data.Add("search%20index%3Dshort%20sourcetype%3Dsrc%20%7C%20head%205", "search")

This becomes search index=short sourcetype=src | head 5 = search, which is the reverse of what you want.

The key comes first, then the value, but you have specified the value first, then the key.

I think this should instead be:

            data.Add("search", "search%20index%3Dshort%20sourcetype%3Dsrc%20%7C%20head%205")

I suspect the same is true of some of your other calls to url.Values.Add(), so you should check them all and be sure.
