Olá, equipe,Estou tentando usar uma biblioteca de código aberto para exibir blocos vetoriais do ArcGIS no meu app.A biblioteca especifica a autenticação por meio de cabeçalhos HTTP de autenticação, que, segundo a documentação, deveria ser compatível:https://developers.arcgis.com/documentation/security-and-authentication/reference/http-header-authentication/Percebi que não é o caso em alguns endpoints, por exemplo:https://basemaps-api.arcgis.com/arcgis/rest/services/World_Basemap_v2/VectorTileServerEle exige um parâmetro de token explícito.Podem verificar como posso especificar cabeçalhos de autenticação para esse endpoint?Obrigado.
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.
