Property Overview

Property Details

tokenValidityNumber

The suggested lifetime of the token in minutes.

Default Value:60

useSignInPageBoolean

If your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server, the IdentityManager will redirect the user to its sign-in page. For instance, let's say an application accesses secure resources from ArcGIS.com or one of its subdomains. Once the application attempts to access this resource, the IdentityManager redirects the user to the ArcGIS.com sign-in page. Once a user successfully logs in, they are redirected back to the application. The same holds true if the application accesses secure resources from ArcGIS Enterprise as the IdentityManager will redirect the user to its sign-in page. If you do not wish for the application to automatically redirect, set this property to false. (Please note that this is not a common scenario. For most, using the OAuth sign-in behavior should handle most of their authentication needs.)

Default Value:true

• dojo/on

Example:

view.on("click", function(event){
  // event is the event handle returned after the event fires.
  console.log(event.mapPoint);
});

registerOAuthInfos(oAuthInfos)

Registers OAuth 2.0 configurations.

Parameter:

oAuthInfos OAuthInfo[] An array of OAuthInfo objects that defines the OAuth configurations.

Example:

require(["esri/identity/OAuthInfo", "esri/identity/IdentityManager"], function(OAuthInfo, esriId) {
  var oAuthInfo = new OAuthInfo({
    appId: "<registered client id>"
  }); // 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) {
  var serverInfo = new ServerInfo();
  serverInfo.server = "http://sampleserver6.arcgisonline.com";
  serverInfo.tokenServiceUrl = "http://sampleserver6.arcgisonline.com/arcgis/tokens/generateToken";
  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:

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.

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:

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.

setRedirectionHandler(handlerFunction)

If your application is on the same domain as *.arcgis.com or ArcGIS Enterprise Server, the IdentityManager will redirect the user to its sign-in page. For instance, let's say an application accesses secure resources from ArcGIS.com or one of its subdomains. Once the application attempts to access this resource, the IdentityManager redirects the user to the ArcGIS.com sign-in page. Once a user successfully logs in, they are redirected back to the application. The same holds true if the application accesses secure resources from ArcGIS Enterprise as the IdentityManager will redirect the user to its sign-in page. Use this method if the application needs to execute custom logic before the page is redirected by creating a custom redirection handler. The IdentityManager calls the custom handler function with an object containing the redirection properties.

Parameters:

handlerFunction Function The function passed to setRedirectionHandler receives an object containing redirection properties. These properties are listed in the table below. Specification: resourceUrl String The URL of the secure resource that triggers the redirection to the ArcGIS.com sign-in page. returnUrlParamName String The application URL where the sign-in page redirects after a successful login. To create the return URL, append the application's URL to signInPage as a parameter. The returnUrlParamName contains the name of the parameter. serverInfo ServerInfo The ServerInfo object describing the server where the secure resource is hosted. signInPage String URL of the sign-in page where users will be redirected.

Example:

require(["esri/IdentityManager"], function(esriId)
{
  esriId.setRedirectionHandler(function(info)
  {
  // Execute custom logic then perform redirect
  window.location = info.signInPage "?"
  info.returnUrlParamName "=" window.location.href;
  });
});

signIn(url, serverInfo, options){Promise<Object>}

Subclasses must implement this method to create and manage the user interface used to obtain a username and password from the end user. It should perform the following tasks:

• challenge the user for a username and password,
• generate a token and return it to the caller.

Parameters:

url String URL for the secured resource.

serverInfo ServerInfo A ServerInfo object that contains the token service URL.

options Object optional See the table below for the structure of the options object. Specification: error Error Error object returned by the server from a previous attempt to fetch the given URL.

Returns:

Type	Description
Promise<Object>	Resolves to an object containing a token.

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.
