We are writing a REST application to access AGS map services. We cannot use the ArcGIS JSAPI - everything I do can only use REST verbs (GET, PUT, etc.)   • We want to access secure map services that are hosted on-premise on ArcGIS Server   • We have on-premise Portal for ArcGIS Server   • ArcGIS Server security (User Store, Role Store, Authentication Tier, and Authentication Mode) uses Portal for ArcGIS To get an Oauth2.0 token I can use this URL: https://<DOMAIN>/portal/sharing/rest/oauth2/token?grant_type=client_credentials&client_id=<CLIENT_ID>&client_secret=<CLIENT_SECRET> Which returns a JSON payload like this: {"access_token":"fCsz6hbXOsnjfIt1j30HAofVMcu3xEhnsgao2rq4_98xOAlf72oR17LYvj1gydJ7ZYnhzxzU4G-vBWNW_0thHQqSYt-HDuzVenv-v6nws1xkGu6XOI3peobXFobZo5QV6NcglZYF6YiFbMM8MPdE7A..","expires_in":7200} To get an old-fashioned REST token I can use this URL: https://<DOMAIN>/portal/sharing/generateToken?f=json&username=<USERNAME>&password=<PASSWORD>&clientip=requestip Which returns a JSON payload like this: {"token" : "KfD9KGedbu2lDrBc2umSVv08XDFCsU8HuKU0yBiFoFk375ahReXmcfVBbsGbGr1iotf003H319dG35T-7Q5-c933dWD0dfLPaflTu4QucS4jJ2Zcz0oIprFspEzk78tHky0IeuHswBudKDbebOQISQ..","expires" : 1453833598866,"ssl" : true} I want to access: https://<DOMAIN>arcgis/rest/services/SampleWorldCities/MapServer?f=json In the pre-Portal for ArcGIS days of REST I could use a URL: https://<DOMAIN>arcgis/rest/services/SampleWorldCities/MapServer?f=json&token=<SOMETOKEN> where <SOMETOKEN> was obtained from the REST token dispenser. HOWEVER: neither of the tokens I’ve obtained from the Portal dispenser nor the REST dispenser work. Both return: {"error":{"code":498,"message":"Invalid Token","details":[]}} THE QUESTIONS:   • Which token dispenser do I use?   • How do I string together a URL that uses a token I have obtain (from the correct source) then I can use to access our secured services?

For a variety of reasons, we'd like to host our webmaps on-premise using Portal for ArcGIS Server instead of ArcGIS Online. That means the content of the webmap has to be consumable by a JSAPI application by its JSON. Also exposed is its webmap ID. esri/arcgis/utils | API Reference | ArcGIS API for JavaScript  indicates that createMap can use an itemID (if hosted at AGOL) or itemData - which will be the JSON that can be embedded in the application - e.g., in a configuration. We have a highly customized JSAPI application - its functionality cannot be recreated using the WAB or any of the templates. Our problem is that our webmaps change quite frequently - it's impractical to export the webmap into JSON and put the JSON into a configuration every time the webmap changes. At the same time, the JSAPI application can only use createMap with an itemID if the webmap is hosted at AGOL. Is there some special magic I can use to consume a locally-host webmap by its itemID? For example, if I knew the URL of the webmap, can I tease the configuration JSON out of it and use that to hydrate the map in the JSAPI app? Just an idea... Discuss... BTW JSAPI 3.x and we won't refactor a release in 4.x until it's been in production for at least a year. TIA ... View more

I've got a map dijit - by default the simple zoom slider (+/-) is in the upper left corner. I want to place it in the upper right corner. According to the documentation I can use this in my CSS: .esriSimpleSliderTL {     top: 50px;     right: 50px } Unfortunately all this does is stretch the zoom slider. Like this: Try it here: http://jsfiddle.net/bEwcD/3/ How to I get that zoom slider 50px by 50px from the upper right? TIA ... View more

We we all know, if you have a web map app that consumes secure services, when you navigate to that page the IdentityManager will provide a login dijit which creates a security. I have a web page named MyWebAppWithSecureServices.html that meets that criteria. I want my users to log in from another html page (MyLoginPage.html) and use that security to do a window.location.replace("MyWebAppWithSecureServices.html"); I want to do this without having to do any magic with a token, like appending it to the URL of a service REST endpoint. I know I need to use "esri/Credential", "esri/IdentityManager", "esri/ServerInfo" to accomplish my goal. I'm having no success. Can you help me wrap my head around this please? TIA In the code below esriId is an instance of "esri/IdentityManager"           function tryCreateCredentialsAndRedirectToAppWithSecureServices() {             var userId = dojo.byId("username").value;             var password = dojo.byId("password").value;             var serverInfo = new ServerInfo();             serverInfo.server = "http://www.MyDomain.com";             serverInfo.tokenServiceUrl = "http://www.MyDomain.com/ArcGIS/tokens/";             esriId.registerServers([serverInfo]);             esriId.generateToken(serverInfo, {                 username: userId,                 password: password             }).then(function(response) {               // got our response from the token dispenser, now register it with the identify manager               var tokenRegistrationObject = {                 expires: response.expires,                 server: serverInfo.server,                 ssl: false,                 token: response.token,                 userId: userId               }               esriId.registerToken(tokenRegistrationObject);               var myCred = esriId.findCredential( "http://www.MyDomain.com", userId);               var idObject = {};                idObject.serverInfos = serverInfo;                var credentials = {};                credentials.userId = userId;                credentials.server = "http://www.MyDomain.com/arcgis";               credentials.token = response.token;                credentials.expires = response.expires;                credentials.ssl = false;                credentials.scope = "server";                credentials.validity = response.validity;                credentials.creationTime = myCred.creationTime;                                idObject.credentials = [credentials];                esri.id.tokenValidity = response.validity;;                esri.id.initialize(idObject);                window.location.replace("MyWebAppWithSecureServices.html");             });           }    ...

I want to hide the ticks on my time slider, there are so many of them (monthly form 2011 to 2020 - in-progress development will bind the timeSlider to some DateTextBox dijits)   How do I style the slider to not display the ticks.   I'm using claro.css   TIA   something like: this.timeSlider = new TimeSlider({ style:HIDE_THE_TICKS}, domConstruct.create("divTimeSlider", {}, timeDiv)); ...

I have a FeatureLayer in my map. I want to query the FeatureLayer and display the results in a esri.dijit.FeatureTable (ie., a subset of the graphics in the FeatureLayer need to be used to populate the FeatureTable). Those are the requirements. Simple, right. What am I missing??? Querying the FeatureLayer directly returns a TypeError: cyclic object value so I can't even create the FeatureLayer to hydrate the FeatureTable with. The code: var myQuery = new Query(); myQuery.returnGeometry = true; myQuery.where = "1=1"; myFeatureLayer.queryFeatures(myQuery,function(queryResults) {     var layerDefinition = {         "geometryType": queryResults.geometryType,         "fields": queryResults.fields     };     var layerDefinition = {         "geometryType": queryResults.geometryType,         "fields": queryResults.fields     };     var featureCollection = {         layerDefinition: layerDefinition,         "featureSet": {             "features": queryResults.features,             "geometryType": queryResults.geometryType         }     };     var featureLayer = new FeatureLayer(featureCollection, {         mode: esri.layers.FeatureLayer.MODE_SNAPSHOT     });     alert("GOT FSET"); }); Using a QueryTask with the url of the FeatureLayer (thus creating round-trips to the server) doesn't work either and errors with  Error: FeatureLayer::_query - query contains one or more unsupported parameters: var queryTask = new QueryTask(myFeatureLayer.url); var query = new Query(); query.where = "1=1"; queryTask.execute(query, function(queryResults) {     var layerDefinition = {         "geometryType": queryResults.geometryType,         "fields": queryResults.fields     };     var layerDefinition = {         "geometryType": queryResults.geometryType,         "fields": queryResults.fields     };     var featureCollection = {         layerDefinition: layerDefinition,         "featureSet": {             "features": queryResults.features,             "geometryType": queryResults.geometryType         }     };     var featureLayer = new FeatureLayer(featureCollection, {         mode: esri.layers.FeatureLayer.MODE_SNAPSHOT     });   myTable = new FeatureTable({     "featureLayer" : featureLayer,     "map" : map   }, 'myTableNode');   myTable.startup();   alert("GOT queryResults"); }); And yes, I know the FeatureTable is in beta at 3.12. And yes, I can already do this in Silverlight and Flex. ... View more

I'm struggling to generate a security token from my on-premise token server. The SDK's documentation is not obvious. My code is:         var si = new esri.ServerInfo();         si.tokenServiceUrl = "http://www.MyTokenDispenser.com/ArcGIS/tokens/";         var imb = new esri.IdentityManagerBase();         imb.on("credential-create", createdCredential);         imb.generateToken({           serverInfo:si,           userInfo:{userName:"MyUserName", password:"MyPassword"}          }); I want to catch the token in the createdCredential method. This code throws an error in the JSAPI API: TypeError: r is undefined http://js.arcgis.com/3.12/ Line 663 We do not want to use the out-of-the-box login that comes with esri.IdentityManager, instead we want to generate our own tokens and credentials. I can use query GET to get a token and I can use esri.request to get a token so long as I enable a proxy, but the code is a bit messy and defeats the purpose of the ArcGIS JSAPI. TIA for any guidance you can offer. ... View more

Greetings: I am working on a mission-critical application that will undergo brief periods of terror. Based on "things happening", there may suddenly be a few 10's of thousands making map requests in a brief interval of time (many minutes to a couple of hours). My client wants to know how an AGOL web map can handle that kind of stress. Rather than writing my own stress test, are there any folks here that have experience with commercial site stressors. I am most interested in how the map responds - the web map will be embedded in another web application hosted elsewhere. I know there are commercial offerings like Blitz, LoadImpact, SiteLoadTesting, and others, but these see more focused on stressing more tradition web applications. So, does anyone here have any experience and sage buts of wisdom on how to stress test an AGOL web map? TIA ... View more
