Token Request Fail

LeeIrminger

Needing to use IdentityManager to generate and register a token so that a secure feature layer located in Portal can be added. I'm doing my best to follow the documentation and referencing examples that I've seen posted here. The token request is failing- please see below for the section of code and the error message, please let me know if you have suggestions. I am new to javascript and the api. Thank you!

 

// Add Server Info

        var serverInfo = new ServerInfo();

        serverInfo.server = "https://x.y.z.com/webadaptor1/rest/services/";

        serverInfo.tokenServiceUrl = "https://x.y.z.com/portal/sharing/rest/generateToken";

        serverInfo.hasPortal = true;

        esriId.registerServers([serverInfo]);

        var userInfo  = {username:"xyz",password:"xyxpw", "client": "referer", "referer": document.URL};

// Generate Token

        esriId.generateToken(serverInfo,userInfo).then(function(data){

          var tokenValue = data.token;

          esriId.registerToken({

            server:"https://x.y.z.com/webadaptor1/rest/services/",

            token:tokenValue

        });

// Add Layer

          //var layerUrl = "https://x.y.z.com/webadaptor/rest/services/folder/feature/MapServer/3";

          var featurelayer = new FeatureLayer("https://x.y.z.com/webadaptor/rest/services/folder/feature/MapServer/3")

          map.addLayer(featurelayer);

        },function(error){

          console.error(error);

        });

Unfortunately it is not possible to generate a token without user credentials. To hide credentials you can skip the token generation part and just register a token in your app. You can then use a crontab (or Task Scheduler for Windows) to replace the token before it expires.

An alternative that I recommend is re-adding the service to your Portal and storing the credentials there. You can then limit access to your application for the new item. Here is some documentation for that workflow. The documentation mentions ArcGIS Online but it works in Portal as well.
