Load secured private layer with app login

RubyStroschein — Thu, 04 Apr 2019 15:22:08 GMT

Hello,

I'm developing angular/ruby on rails web application. For arcgis we are using javascript api. Is it possible to access private layers hosted on arcgis online with app id.

Layer.fromPortalItem({ portalItem: { // autocasts new PortalItem() id: "8444e275037549c1acab02d2626daaee" } }).then(function(layer){ // add the layer to the map map.add(layer); });

Hi Rudy, absolutely. See this page on app logins and using a proxy:

Hello Noah,

Thanks for reply. Do you have some sample code? Can I login using proxy?

This is stated in documentation:

App login can be used to access any of these services:

Public content (basemaps, layers shared publicly);
Geocoding;
Routing and Directions;
Demographic Data (GeoEnrichment);
Esri Premium Maps and Layers which require a subscription;
Elevation Analysis.

There are certain limitations and restrictions using app login.

Hmmm, I guess you're not allowed to app logins for private layers/services. Well, you're certainly allowed to use the Esri resource proxy for this use case.

Thanks I intend to try this. Can printtask service work with layers that go trough proxy?

Yes, this should work fine. You may need to host your own printing service though.

We managed to access protected layer using arcgis toke, it is easier to use than proxy.

$http.get('/esri_layer/token').success(function (resp) {

w.IdentityManager.registerToken({

server: url,

token: resp.access_token,

expires: resp.expires,

ssl: true

});

Can printing service be used with Arcgis online developer account.

It seams that print service is not working properly for examples, they are failing to generate print
