Authorization in Angular UI

OAuth is preconfigured in Angular application templates. So, when you start a project using the CLI (or Suite, for that matter), authorization already works. ABP Angular UI packages are using angular-oauth2-oidc library for managing OAuth in the Angular client. You can find OAuth configuration in the environment.ts files.

Authorization Code Flow

import { Config } from '@abp/ng.core';

const baseUrl = 'http://localhost:4200';

export const environment = {
  // other options removed for sake of brevity

  oAuthConfig: {
    issuer: 'https://localhost:44305',
    redirectUri: baseUrl,
    clientId: 'MyProjectName_App',
    responseType: 'code',
    scope: 'offline_access MyProjectName',
  },

  // other options removed for sake of brevity
} as Config.Environment;

This configuration results in an OAuth authorization code flow with PKCE. According to this flow, the user is redirected to an external login page which is built with MVC. So, if you need to customize the login page, please follow this community article.

Resource Owner Password Flow

If you implemented the Angular UI account module to your project, you can switch the flow to resource owner password flow by changing the OAuth configuration in the environment.ts files as shown below:

import { Config } from '@abp/ng.core';

export const environment = {
  // other options removed for sake of brevity

  oAuthConfig: {
    issuer: 'https://localhost:44305',
    clientId: 'MyProjectName_App',
    dummyClientSecret: '1q2w3e*',
    scope: 'offline_access MyProjectName',
  },

  // other options removed for sake of brevity
} as Config.Environment;

According to this flow, the user is redirected to the login page in the account module.
