Hallo team,Ik probeer een opensourcebibliotheek te gebruiken om ArcGIS-vectortegels in mijn app weer te geven.Volgens de bibliotheek verloopt de autorisatie via HTTP-authenticatieheaders, die volgens de documentatie ondersteund zouden moeten worden:https://developers.arcgis.com/documentation/security-and-authentication/reference/http-header-authentication/Ik merk dat dit voor sommige eindpunten niet het geval is, bijvoorbeeld:https://basemaps-api.arcgis.com/arcgis/rest/services/World_Basemap_v2/VectorTileServerHiervoor is een expliciete tokenparameter vereist.Kunnen jullie nagaan hoe ik authenticatieheaders voor dit eindpunt kan opgeven?Bedankt.
On second thought the library may be doing the wrong thing.I see that initial request to get the tiles url contains the token so that should work without the auth header.I don't see an option to delete this post.
@msuk1the way to do this is to call the basemap style service with your authentication token in the header as documented here: https://developers.arcgis.com/rest/basemap-styles/arcgis-navigation-style-get/#token
subsequent tile requests should then supply the token. This is typically done with the mapping library. You can review some of the open-source implementations provided on https://developers.arcgis.com/documentation/#open-source-mapping-libraries, Esri Leaflet is a popular one that demonstrates this.
Thanks John, that's what I realised eventually.The style contains a source field, and the library I amusing was making a subsequent request to the url specified in the source.There's no obvious reason for it so I have asked the library owner to fix it.
