Vumark generation api usage with react

May 26, 2020 - 1:57pm #1

Hi i'm trying to generate an instance of a vumark via the web service I've already setup the database, I managed to make the request but I'm getting the 401 (Unauthorized) error code. Here is my code any help would be great.



export const generateInstanceOfMarker = (vuMarkid) => {

    const date = new Date().toUTCString();



    var StringToSign = "POST" + "\n" + "B1E249BECDC69913C8BCCA597C2AF8DD" + "\n" + "application/json" + "\n" + date + "\n" + "https://vws.vuforia.com/targets/{target-id}/instances/" + vuMarkid;



    var Signature = new HmacSha1('base64');

    Signature.digest({server_secret_key}, StringToSign);



    const Auth = 'VWS {server_access_key} : ' + Signature;



    return dispatch => {

        axios

            .post(

                'https://vws.vuforia.com/targets/{target-id}/instances',

                {

                    headers: {

                        'Authorization': Auth,

                        'accept': 'image/svg+xml'

                    },

                    body: {

                        instance_id: vuMarkid

                    }

                }

            )

            .then(response => {

                console.log(response);

                dispatch(onCreateInstanceEvent(response.data));

            })

            .catch(error => {

                console.log(error);

            })



    };

};



I create the md5 hash with this page : https://passwordsgenerator.net/md5-hash-generator/ and the text that i has was the body : body: {

                        instance_id: vuMarkid

                    }



Dont know which part of the authentification code is wrong.



Thanks!

Hi,

Unfortunately you are not able to generate the vumark using code with the developer license.

It is only possible with the Pro License.

Thank you.
