Creating AGSCredentials using Token and Referer

smaawais — Wed, 02 Dec 2020 06:21:03 GMT

When view controller is loaded, it makes an API call to our server with the app identifier which is used by the API to generate a token using ArcGIS service. The response contains portal URL, token and mapId. The portal URL can be of following format:

https://atlas.{client Name}.com
https://{client Name}.maps.arcgis.com

and then use following code to load map and related basemaps

agsCredential = AGSCredential(token: portalToken, referer: referer) let portal = AGSPortal(url: portalURL, loginRequired: true) portal.credential = agsCredential let portalItem = AGSPortalItem(portal: portal, itemID: mapId) let map = AGSMap(item: portalItem) esriMapView.map = map map.load { (error) in // handle error or handle successfully loaded map // load base maps }

Although I have provided the credentials, I still see credential challenge popup. If I create AGSCredentials using userName and password, it works fine.

Our requirement is to use token rather than userName and password, what is the best approach to use the token?

I also been communication on git, so I tried and what worked is in following link of ESRI iOS Repo.

What type of layers present in the portalItem? Are they hosted feature layers? If yes, it requires another credential/token generated using portalToken. Can you please post the credential challenge information?

Hi Nimesh,

The layers I wan to access are within the basemap, how set credentials again? Following is how I am doing right now. Also what credential challenge information are you after?

let agsCredentials = AGSCredential(token: credentialToken, referer: referer)

let portal = AGSPortal(url: portalURL, loginRequired: true)

portal.credential = agsCredentials

let portalItem = AGSPortalItem(portal: portal, itemID: mapId)

let map = AGSMap(item: portalItem)

esriMapView.map = map

map.load { (error) in

if let _ = error {

print(error!.localizedDescription)

self.delegate?.mapLoadingFailed()

} else {

var layers = MapSpecificLayers()

for layer in map.operationalLayers {

if let agsLayer = layer as? AGSLayer {

let mSpecifiLayer = MapSpecificLayer(id: agsLayer.layerID,

layerName: agsLayer.name,

isVisible: agsLayer.opacity == 0 ? false : true)

layers.append(mSpecifiLayer)

}

self.layersViewModel.mapSpecificLayersFetched(mapSpecificLayers: layers)

self.delegate?.mapLoaded()

}

portal.fetchBasemaps { (bmaps, err) in

print(">>>>>. BASE MAP FETCHED \(bmaps?.count)<<<<<")

}

Can you capture all request/responses and send to me in direct message? If possible, send a reproducible sample project too so I can help you where to set another credential.
