How can I retrieve the portal user name in a custom WAB widget?

BenFerguson — Mon, 28 Sep 2015 20:35:34 GMT

I'm building a custom widget in WAB. I need to retrieve the user name of the user logged into the Portal. Is there a property or function in WAB somewhere that can provide that?

Hi Ben,

You can define portalUtils in widget and access user through the portal instance:

define([
    'jimu/BaseWidget',
  'jimu/portalUtils',
    'dojo/_base/declare'
  ],
function(BaseWidget, portalUtils, declare) {

...
this.portal = portalUtils.getPortal(this.appConfig.portalUrl);
username = this.portal.user.username;
...

Thank you Herdis.

I hadn't found the portalUtils.getPortal() function. That is what I needed to get a reference to the portal instance the WAB is using.

I wish WAB was better documented.

Does this work for in-panel widgets?

I am getting a: " Uncaught TypeError: Cannot read property 'portalUrl' of undefined " error when I use this code. When I don't have this code, my template loads correctly without any errors and I do have the correct portalUrl in place??

did you ever figure this out? having the same issue. sometimes i think people find it funny to post incomplete examples instead or withhold which version of the api they are using.

I can't say how much has changed in five years - but I suggest you to debug it by looking into the properties of 'this' in this.appConfig.portalUrl - since the error message implies that appConfig is null - maybe this has changed since 2015? Or maybe the 'this' in your script point to something else? Anyway, good luck.
