## Cookies with a Pydantic Model { #cookies-with-a-pydantic-model }

Declare the **cookie** parameters that you need in a **Pydantic model**, and then declare the parameter as `Cookie`:

	data := url.Values{}
	data.Set("grant_type", "client_credentials")
	req, err := http.NewRequest(http.MethodPost, idpEndpoint, strings.NewReader(data.Encode()))
	if err != nil {
		return nil, err
	}
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
	req.SetBasicAuth(clientID, clientSecret)
	t := &http.Transport{
		TLSClientConfig: &tls.Config{
			InsecureSkipVerify: true,
		},
	}
	hclient := http.Client{

        } else {
            off = in.readDirect(buf, 0, buf.length);
        }

        if (buf[0] != 5 && buf[1] != 0) {
            throw new IOException("Unexpected DCERPC PDU header");
        }

        flags = buf[3] & 0xFF;
        // next read is start of new frag
        isStart = (flags & DCERPC_LAST_FRAG) == DCERPC_LAST_FRAG;

        length = Encdec.dec_uint16le(buf, 8);
