PUT request GO LANG

doPut.go

func doPut(url string) {
	client := &http.Client{}
	request, err := http.NewRequest("PUT", url, strings.NewReader("<golang>really</golang>"))
	request.SetBasicAuth("admin", "admin")
	request.ContentLength = 23
	response, err := client.Do(request)
	if err != nil {
		log.Fatal(err)
	} else {
		defer response.Body.Close()
		contents, err := ioutil.ReadAll(response.Body)
		if err != nil {
			log.Fatal(err)
		}
		fmt.Println("The calculated length is:", len(string(contents)), "for the url:", url)
		fmt.Println("   ", response.StatusCode)
		hdr := response.Header
		for key, value := range hdr {
			fmt.Println("   ", key, ":", value)
		}
		fmt.Println(contents)
	}
}

How can I make a put request without body?

Just pass nil to the third argument:

request, err := http.NewRequest("PUT", url, nil)
