Now let's review those changes step by step.

## OAuth2 Security scheme { #oauth2-security-scheme }

The first change is that now we are declaring the OAuth2 security scheme with two available scopes, `me` and `items`.

The `scopes` parameter receives a `dict` with each scope as a key and the description as the value:

        "GET",
        ":scheme",
        "http",
        ":path",
        "/",
        ":authority",
        "www.example.com",
      ),
    )
  }

    bytesIn.writeByte(0x82) // == Indexed - Add ==
    // idx = 2 -> :method: GET
    bytesIn.writeByte(0x86) // == Indexed - Add ==
    // idx = 7 -> :scheme: http

	v, err := li.Get()

	}

	if displayCreds {

    /**

/**
 * Protocols that OkHttp implements for [ALPN][ietf_alpn] selection.

 * ## Protocol vs Scheme
 *
 * Despite its name, [java.net.URL.getProtocol] returns the [scheme][java.net.URI.getScheme] (http,
 * https, etc.) of the URL, not the protocol (http/1.1, spdy/3.1, etc.). OkHttp uses the word
 * *protocol* to identify how HTTP messages are framed.
