# HTTP Basic Auth

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.

func (a *Args) Validate() error {
	req, err := http.NewRequest(http.MethodPost, a.URL.String(), bytes.NewReader([]byte("")))
	if err != nil {
		return err
	}

	req.Header.Set("Content-Type", "application/json")
	if a.AuthToken != "" {
		req.Header.Set("Authorization", a.AuthToken)
	}

	client := &http.Client{Transport: a.Transport}
	resp, err := client.Do(req)
	if err != nil {
		return err
	}

     * Some fields specify the offset from the beginning of the header. This
     * field should be used for calculating that. This would likely be zero
     * but an implemantation that encorporates the transport header(for
     * efficiency) might use a different initial bufferIndex. For example,
     * to eliminate copying data when writing NbtSession data one might
     * manage that 4 byte header specifically and therefore the initial
