Where does the parameter "portalUser" come from?

JoseSanchez — Tue, 21 Mar 2017 17:43:09 GMT

Hello everyone,

I do not understand very well the notation for this function: function (portalUser){

The parameter "portalUser" where is it populated and declared?

Is there any online converted that changes from AMD to other structure easier to read?

This function is used in this sample: https://developers.arcgis.com/javascript/3/jssamples/portal_oauth_inline.html

Thanks

function displayItems(){
new arcgisPortal.Portal(info.portalUrl).signIn().then(
function (portalUser){
console.log("Signed in to the portal: ", portalUser);

domAttr.set("userId", "innerHTML", portalUser.fullName);
domStyle.set("anonymousPanel", "display", "none");
domStyle.set("personalizedPanel", "display", "block");

queryPortal(portalUser);
}
).otherwise(
function (error){
console.log("Error occurred while signing in: ", error);
}
);

Jose,

"portalUser" is the promise result of the new arcgisPortal.Portal(info.portalUrl).signIn() function.

signIn():
Prompts the user using the IdentityManager and returns a deferred that, when resolved, returns the PortalUser for the input credentials.

Thanks Robert,

In this sample, how do I instantiate "portalUser" if I already log in into the web application. ?

I want to add this code to check the groups from an user that already logged in.

require([
"dojo/_base/array", ...
], function(array, ... ) {
portalUser.getFolders().then(function(folders){
array.forEach(folders,function(folder){
if(folder.title === 'javascript'){
folderid = folder.id;
}
});
});
...
});

Jose,

You can get the portal user from the portal object using the getPortalUser() method:

Thanks again,

what I do not understand is how the object "portal" gets instantiated? or how can declare an object myPortal = initialize it with "portal".

Fired when the portal has loaded. Once the portal has loaded the properties and methods of the Portal class are available. (Added at v3.6)

Sample:

portal.on("load", function(){
  console.log(portal.allSSL);
});

The Portal class uses the IdentityManager to signin a user so if the user is already authenticated when you use Portal signIn I would not expect it to re-prompt for login so you should be good just calling portal signin.

What I don't understand is how the object "portal" gets populated. This is my function

require([
"esri/arcgis/Portal", ...

], function(arcgisPortal, ... ) {

//Retrieves user information.

checkUser: function() {

portal = new arcgisPortal ??????????? How is this object instantiated ??????

console.log(portal.allSSL);

console.log(portal.signIn());

console.log(portal.getPortalUser());

Jose,

If you are saying that your app is already logged in then that means the IdentityManger was used for some secured Portal resource. So just use:

var portal = new arcgisPortal.Portal('http://blahblah.maps.arcgis.com');

Thank you Robert.

One last questions,

how do I instantiate PortalGroup ?

var portalgroup = new ????

or do I need to run a query on Portal to get all groups?

Thanks

You have to use portal queryGroups as PortalGroup does not have a constructor method.

Hi Robert,

I wrote this code:

var portal = new arcgisPortal.Portal('http://[my organization].maps.arcgis.com');

var portalUser = new portal.getPortalUser();

var myArray = portalUser.getGroups;

Is that correct to declare portalUser = new portal.getPortalUser();

Debugging the program I get the message "myArray is Undefined."

Jose,

No portal.getPortalUser() is a method not a constructor that would use new.

Hi Robert,

I am getting the error message below:

var portal = new arcgisPortal.Portal('http://[my organization].maps.arcgis.com');

var portalUser = portal.getPortalUser();

Error message in debugging mode: variable portalUser is undefined.

Jose,

Then it is not recognizing you as being signed in. You need to do

portal.signIn().then(function() {
  var portalUser = portal.getPortalUser();‍‍

Re: Where does the parameter "portalUser" come from?

JoseSanchez — Wed, 22 Mar 2017 13:32:30 GMT

Robert,

Is this correct?

In debugging mode it does not go inside portal.signIn() , so it does not executes the function:

var portal = new arcgisPortal.Portal('http://[my organitation].maps.arcgis.com');

              portal.signIn().then(function() {
                  var portalUser = portal.getPortalUser();
                  console.log("Signed in to the portal: ", portalUser);
                  console.log(portalUser.fullName);
                  var myArray = null;

var myArray = portalUser.getGroups;

});

.....

RobertScheitlin__GISP — Sat, 11 Dec 2021 12:36:11 GMT

Jose,

It looks fine to me except that the signIn method returns a potalUser as the deferred result:

var portal = new arcgisPortal.Portal('http://[my organitation].maps.arcgis.com');
portal.signIn().then(function (loggedInUser){‍‍‍
  console.log("Signed in to the portal: ", loggedInUser‍‍‍);
  console.log(loggedInUser‍‍‍.fullName);
  var myArray = null;
  var myArray = loggedInUser‍‍‍.getGroups;
});‍‍‍‍‍‍‍

Are you adding a break point inside the then portion?
