How to get user logged in without passing through login dialog in javascript ?

LaurentDuruflé — Fri, 27 Dec 2019 15:05:42 GMT

From sample provided here I would like to login using a specific login/password embedded in my javascript code without any login dialog (login will be transparent to user). Any idea how to customized the JS code from this sample to achieve this objective ?

sample using login dialog (from ArcGIS API for JavaScript Sandbox 😞

var map, cred = "esri_jsapi_id_manager_data"; // cookie/local storage name

require([

"dojo/_base/unload",

"dojo/cookie",

"dojo/json",

"dojo/parser", "esri/config", "esri/IdentityManager", "esri/layers/FeatureLayer",

"esri/map",

"dijit/layout/BorderContainer",

"dijit/layout/ContentPane",

"dojo/domReady!",

], function (baseUnload,

cookie,

JSON,

parser, esriConfig, esriId, FeatureLayer,

Map){

// store credentials/serverInfos before the page unloads

baseUnload.addOnUnload(storeCredentials);

// look for credentials in local storage

loadCredentials();

parser.parse();

esriConfig.defaults.io.proxyUrl = "/proxy/";

map = new Map("mapCanvas", {

basemap: "topo",

center: [-120.723, 35.165],

zoom: 12

});

//add the secure service - token is required

var secureLayer = new FeatureLayer("https://sampleserver6.arcgisonline.com/arcgis/rest/services/SaveTheBay/FeatureServer/0",

{

mode: FeatureLayer.MODE_ONDEMAND,

outFields: ["*"]

});

map.addLayer(secureLayer);

function loadCredentials(){

var idJson, idObject;

if (supports_local_storage()) {

// read from local storage

idJson = window.localStorage.getItem(cred);

}

else {

// read from a cookie

idJson = cookie(cred);

}

if (idJson && idJson != "null" && idJson.length > 4) {

idObject = JSON.parse(idJson);

esriId.initialize(idObject);

}

else {

// console.log("didn't find anything to load :(");

}

function storeCredentials(){

// make sure there are some credentials to persist

if (esriId.credentials.length === 0) {

return;

}

// serialize the ID manager state to a string

var idString = JSON.stringify(esriId.toJson());

// store it client side

if (supports_local_storage()) {

// use local storage

window.localStorage.setItem(cred, idString);

// console.log("wrote to local storage");

}

else {

// use a cookie

cookie(cred, idString, {expires: 1});

// console.log("wrote a cookie :-/");

}

function supports_local_storage(){

try {

return "localStorage" in window && window["localStorage"] !== null;

} catch (e) {

return false;

}

});
