The Minimal InfluxDB Client in Go

While you can get a proper InfluxDB client library for Go, sometime there's no substitution for rolling one yourself - especially since InfluxDB's Line Protocol is really easy.

It's just a matter of constructing a correct URL and setting up just two headers. Something like this:

Function  Copy
func sendInfluxData(line string, baseUrl string, org string, bucket string, token string) {
    var url string
    if len(org) > 0 {
        url = fmt.Sprintf("%s/api/v2/write?org=%s&bucket=%s",
			  baseUrl, org, bucket)
    } else {
        url = fmt.Sprintf("%s/api/v2/write?bucket=%s",
			  baseUrl, bucket)
    }

    request, _ := http.NewRequest("POST", url, strings.NewReader(line))
    request.Header.Set("Content-Type", "text/plain")
    if len(token) > 0 {
        request.Header.Set("Authorization", "Token " + token)
    }

    response, _ := http.DefaultClient.Do(request)
}

And yes, code doesn't do error checking nor it has any comments. Deal with it. ;)
