JavaScript Refresh credential and prevent Identity Manager pop-up

BlairJones

I want to use tokens with a short expire time,  generate a new token before expire, and then replace credentials for layers in a map.

My problem is how to prevent ArcGIS Identity Manager from continuing to create a pop-up requesting credentials.

I start with dom.byId('tokenText').value as a token having a short expire time.  I start a JavaScript timer giving 30 seconds to create a new token.

I try to update credentials; I'm not sure I know what I'm doing...  Pop-ups from Identity Manager occurs anyway.

Here is the "guts" of my work;  any suggestions will be cheerfully accepted!

var tokenText,layerSource;

...

ready(function() {

function renewToken(urlOfMapService){

    xhr.get({

// The URL of the request

        url: "refreshToken.aspx",

// Allow 10 seconds to get new token

        timeout: 10000,

// Send the existing token

        content: {

            token: tokenText

        },

// The success callback with result from server

        load: function(result) {

//--- result is a Comma Separated Value string of creatTime, expireTime, tokenText

            var dataArray = result.split(',');

            dataArray.push(urlOfMapService);

//--- UPDATE CREDENTIALS

            initializeCredentials( dataArray );

            app.map.getLayer("Warblers").credential = credential;

            },

// The error handler  

        error: function(message) {

            alert("error:"+message);

        }

    });

}

function initializeCredentials(a) {

//--- a is Array  of creatTime, expireTime, tokenText, resourceURL

//--- call renewToken before expire

    waitTime = parseInt(a[1],10)

        - parseInt(a[0],10)

        - 30000;

    credentialsTimer = setTimeout(function(){renewToken(DGIFData)}, waitTime );

//--- fwisCredentials is a global Object variable assigned using JSON in a loaded script

    tokenText = a[2];

    credential = fwisCredentials.credentials[0];

    credential.creationTime = a[0];

    credential.expires = a[1];

    credential.token = tokenText;

    credential.resources.push(a[3]);

    fwisCredentials.credentials = [credential];

    kernel.id.initialize(fwisCredentials);

}

esri.config.defaults.io.proxyUrl = "https://my.server.com/proxypage_net/proxy.ashx";

    layerSource = "https://my.server.com/arcgis/rest/services/Test/Warblers/MapServer";

//--- initial token  and times are available at ready event

    tokenText = dom.byId('tokenText').value;

    initializeCredentials( [

        dom.byId('tokenCreateTime').value,

        dom.byId('tokenExpireTime').value,

        tokenText,

        layerSource

    ]);

    app.map = new esri.Map("map", {

        center: [-78.839150, 38.061840],

        zoom: 7,

        basemap: "topo",

        slider: true,

        showAttribution:true,

        logo: false,

        autoResize: true

    });

//===LAYER LIST AND MAP SERVICES=======================================================================================

    var layerObject = new ArcGISDynamicMapServiceLayer(layerSource,

       { id: "Warblers", opacity: .8 });

    var flRegions = new FeatureLayer("https://my.server.com/arcgis/rest/services/Public/Agency_Public/FeatureServer/9", {

        mode: FeatureLayer.MODE_ONDEMAND

    });

    app.map.addLayers([flRegions, layerObject]);

  });  // ready function end

Thanks Kelly,

I have looked again at the proxy program code and I understand  that the proxy is used to fetch each map tile and

a new token is created and tried when the server request returns an error.

In trying to understand ArcIS API with regard to credentials, I am trying to update within the client web page.

The "simple" solution I have found using only ArcGIS JavaScript API is to:

0)   not use credential objects and not use kernel.id.initialize()

1)  add a new layer

var tokenText = aGoodTokenString;

var layerObject = new ArcGISDynamicMapServiceLayer(urlOfMapService + "?token=" + tokenText

           ,{   id: layerID  });

app.map.addLayers([layerObject]);

2) using setTimeout()

     update the layer.url with a new token string:

     tokenText = createNewTokenStringPrivateFunction(tokenText);

     map.getLayer(layerID).url = urlOfMapService + "?token=" + tokenText;

There is already an instance of the proxy running on my ArcGIS server.  I am gathering client name and password from another independent web server.  The generated client web page does not have username and password to pass to the proxy.

I now have a choice to either modify the proxy for my needs, use client side JavaScript to renew the url directly, or both.
