Esri Leaflet - Zugriff auf Premium ArcGIS Online-Inhalte - Fehler 400

Question

Hallo,

Ich habe Interesse an diesem Beispiel: https://esri.github.io/esri-leaflet/examples/premium-content.html

(Ich möchte eine private Ebene in mein Esri-Leaflet-Projekt mit einer Authentifizierung hinzufügen.)

Das Beispiel funktioniert einwandfrei auf der Esri-Leaflet-Webseite. Aber wenn ich es auf meiner eigenen Seite (in einer doc.html auf meinem Computer) versuche, funktioniert es nicht. Wenn ich auf den Link "Add trafic layer" klicke, erscheint die Meldung "'Invalid redirect_uri - error 400".

Weiß jemand warum?

Danke,

Thanks for your response.

To be precise, I have a feature layer in my arcgis online account and I simply want to share it in private in my esri leaflet project (Web app) without using ArcGIS for developper . Is there a method  to put my user name and password in my code so the feature layer can appear in my project ? (Even if it's not recommanded)

That sample utilizes browser based named user login, which requires that you create and register an application of your own in ArcGIS Online.

Browser-based Named User Login | ArcGIS for Developers

this model necessitates that you identify where your application is hosted (both while it is being developed and in production) via redirect uris of your own so that ArcGIS Online doesn't allow folks to sign and in and pass their credentials to an unknown malicious third party.
