IdentityManager

AMD: require(["esri/identity/IdentityManager"], (esriId) => { /* code goes here */ });
ESM: import esriId from "@arcgis/core/identity/IdentityManager";
Class: esri/identity/IdentityManager
Since: ArcGIS API for JavaScript 4.0

This object provides the framework and helper methods used in managing user credentials for the following resources:

  • Secured ArcGIS.com or ArcGIS Enterprise portal resources (e.g. web maps).

  • ArcGIS Server resources secured using token-based authentication. Note that only ArcGIS Server versions 10 SP 1 and greater are supported. If your application accesses services from different domains, it is deemed a cross-domain request and you need to setup a proxy or use CORS (if supported by browser). If CORS is supported, the Identity Manager knows to make a request to the token service over https.

Authentication requests over http are prevented because sensitive data sent via GET can be viewed in server logs. To prevent this, the Identity Manager requires that you use POST over https to ensure your credentials are secure. View the Use a proxy and CORS help topic for more details.

The IdentityManager module is slightly different than other modules in the API. Instead of returning a class constructor, it returns a singleton instance that has already been created by this module.

Method Details

checkAppAccess(resUrl, appId){Promise<Object>}
Since: ArcGIS API for JavaScript 4.10

Returns a credential if the user has already signed in to access the given resource and is allowed to do so when using the given application id. In addition, it also returns a boolean, viewOnly, property that indicates whether the app is only viewable. The default is false. If the user has not signed in or does not have access, then the promise will be rejected and its error callback will be called.

This scenario is generally not common unless you are building a licensed app. Also, please note that this method should only be used if your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server and is only applicable to applications registered as items in the Esri organization.

Parameters:
resUrl String

The resource URL.

appId String

The registered OAuth application id.

Returns:
Type Description
Promise<Object> Resolves to an object which contains the following properties:
Property Type Description
credential Credential The credential of the user.
viewOnly boolean Indicates whether the app is only viewable. Default is false.
checkSignInStatus(resUrl){Promise<Credential>}

Returns the Credential if the user has already signed in to access the given resource. If the user has not signed in, then the promise will be rejected and its error callback will be called.

Parameter:
resUrl String

The resource URL.

Returns:
Type Description
Promise<Credential> Resolves to the returned credential of the signed-in user.
destroyCredentials()

Destroys all credentials. It is good practice to call this method if working with an application that contains sign-out functionality as any tokens generated via OAuth will automatically be revoked.

disablePostMessageAuth()
Since: ArcGIS API for JavaScript 4.19

Disables the use of window.postMessage to serve authentication requests that were enabled by enablePostMessageAuth. This should be called to prevent memory leaks in SPA routing apps when they need to transition routes. Setting this this helps clean up and remove any windows's message event listeners that enablePostMessageAuth added.

Please refer to the topic, Passing authentication to IFramed apps for additional information. The main differences are:

  • The ArcGIS REST JS API's enablePostMessageAuth method's signature is different than what is provided in the ArcGIS API for JavaScript as explained here.
  • Step three, i.e. Embed App boots and Requests Auth, does not apply when using the ArcGIS API for JavaScript.
See also:
emit(type, event){Boolean}
Since: ArcGIS API for JavaScript 4.5

Emits an event on the instance. This method should only be used when creating subclasses of this class.

Parameters:
type String

The name of the event.

event Object
optional

The event payload.

Returns:
Type Description
Boolean true if a listener was notified
enablePostMessageAuth(resUrl)
Since: ArcGIS API for JavaScript 4.19

Enables the IdentityManager to serve authentication requests for the given resource from apps running in child iframes. The only apps that will be allowed to request the credential are ones that are either running at *.arcgis.com, or are running at the same origin as the host app. Requests from other apps will be ignored.

Only one resource may be authenticated in this manner at any one time. The URL of the resource should be used as the value of a parameter named arcgis-auth-portal that is included in the iframe's src URL. The iframe's src URL should also include another parameter named arcgis-auth-origin with a value of window.location.origin. Both of these parameter values should be URL-encoded using encodeURIComponent. These parameters are used by the IdentityManager, or the UserSession running in the iframe app when it needs the user's authentication to access a given resource.

Please refer to the topic, Passing authentication to IFramed apps for additional information. The main differences are:

  • The ArcGIS REST JS API's enablePostMessageAuth method's signature is different than what is provided in the ArcGIS API for JavaScript as explained here.
  • Step three, i.e. Embed App boots and Requests Auth, does not apply when using the ArcGIS API for JavaScript.

isBusy(){Boolean}

Indicates if the IdentityManager is busy accepting user input. For example, it returns true if the user has invoked signIn and is waiting for a response.

Returns:
Type Description
Boolean Whether IdentityManager is currently accepting user input.
on(type, listener){Object}

Registers an event handler on the instance. Call this method to hook an event with a listener. See the Events summary table for a list of supported events.

Parameters:

An event or an array of events to listen for.

listener Function

  }); // required parameter
  esriId.registerOAuthInfos([oAuthInfo]);
});
registerServers(serverInfos)

Register secure servers and the token endpoints.

Parameter:
serverInfos ServerInfo[]

An array of ServerInfos objects that defines the secure service and token endpoint. The IdentityManager makes its best guess to determine the location of the secure server and token endpoint. Therefore, in most cases calling this method is not necessary. However, if the location of your server or token endpoint is not standard, use this method to register the location.

Example:
require(["esri/identity/ServerInfo", "esri/identity/IdentityManager"], function(ServerInfo, esriId) {
  let serverInfo = new ServerInfo();
  serverInfo.server = "http://sampleserver6.arcgisonline.com";
  serverInfo.tokenServiceUrl = "http://sampleserver6.arcgisonline.com/arcgis/tokens/generateToken";
  serverInfo.hasServer = true;
  esriId.registerServers([serverInfo]);
});
registerToken(properties)

Registers the given OAuth 2.0 access token or ArcGIS Server token with the IdentityManager. See registerOAuthInfos for additional information. The registerToken method is an advanced workflow for pre-registering long-term tokens for when you don't want users to sign in. See also resource-proxy for another workflow to achieve this result.

Once a user logs in, the access token is registered with the IdentityManager. Subsequently, every AJAX request made by the application forwards this token when accessing web maps and other items stored in ArcGIS Online, or resources on your server.

Parameters:
Specification:
properties Object

See the table below for the structure of the properties object.

Specification:
expires Number
optional

Token expiration time specified as number of milliseconds since 1 January 1970 00:00:00 UTC.

server String

For ArcGIS Online or Portal, this is https://www.arcgis.com/sharing/rest or similar to https://www.example.com/portal/sharing/rest. For ArcGIS Server this is similar to https://www.example.com/arcgis/rest/services.

ssl Boolean
optional

Set this to true if the user has an ArcGIS Online organizational account and the organization is configured to allow access to resources only through SSL.

token String

The access token.

userId String
optional

The id of the user who owns the access token.

setOAuthRedirectionHandler(handlerFunction)

Once a user successfully logs in, they are redirected back to the application. Use this method if the application needs to execute custom logic before the page is redirected. The IdentityManager calls the custom handler function with an object containing redirection properties.

Parameter:
handlerFunction handlerCallback

When called, the callback passed to setOAuthRedirectionHandler receives an object containing the redirection properties.

Example:
require(["esri/identity/IdentityManager"],
function(esriId)
{
 esriId.setOAuthRedirectionHandler(function(info)
  {
   // Execute custom logic then perform redirect
   window.location = info.authorizeUrl + "?" + ioquery.objectToQuery(info.authorizeParams);
  });
});
setOAuthResponseHash(hash)

Use this method in the popup callback page to pass the token and other values back to the IdentityManager.

Parameter:
hash String

The token information in addition to any other values needed to be passed back to the IdentityManager.

setProtocolErrorHandler(handlerFunction)

When accessing secured resources, the IdentityManager may prompt for username and password and send them to the server using a secure connection. Due to potential browser limitations, it may not be possible to establish a secure connection with the server if the application is being run over HTTP protocol. In such cases, the Identity Manager will abort the request to fetch the secured resource. To resolve this issue, configure your web application server with HTTPS support and run the application over HTTPS. This is the recommended solution for production environments. However, for internal development environments that don't have HTTPS support, you can define a protocol error handler that allows the Identity Manager to continue with the process over HTTP protocol.

Parameters:
Specification:
handlerFunction Function

The function to call when the protocol is mismatched.

Specification:
resourceUrl String

The secure resource URL.

serverInfo ServerInfo

ServerInfo object describing the server where the secure resource is hosted.

toJSON(){Object}

Return properties of this object in JSON format. It can be stored in a cookie or persisted in HTML5 LocalStorage and later used to:

  • Initialize the IdentityManager the next time a user opens your application.
  • Share the state of the IdentityManager between multiple web pages of your website. This way users will not be asked to sign in repeatedly when they launch your app multiple times or when navigating between multiple web pages in your website.
Returns:
Type Description
Object The JSON object representing the IdentityManager instance calling this method.

Type Definitions

handlerCallback(authorizeParams, authorizeUrl, oAuthInfo, resourceUrl, serverInfo)

The callback to execute when setOAuthRedirectionHandler() is called.

Parameters:
authorizeParams Object

Object containing authorization parameters used to access the secure service. See the table below describing the properties of this object.

Specification:
