How do i make a request with HttpClient in Angular5 with OIDC OAuthService for current user informations?

angularjs

#1

I need to make GETs through HttpClient to get information about users. How do i do it in a service?
Right now i was able to correctly login using this guide, but now i need to make http requests in my injectable service.
I’m new to the frontend world, new to Angular and new with Okta’s APIs and I’m not finding any complete yet simple example on how do it
Thank you for your attention.

Hello @Lamba92. You might want to check out Build a Basic CRUD App with Angular 5.0 and Spring Boot 2.0. It uses an HttpInterceptor to add an authorization header.

import { Injectable } from '@angular/core';
import { HttpRequest, HttpHandler, HttpEvent, HttpInterceptor } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import { OktaAuthService } from '@okta/okta-angular';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  constructor(private oktaAuth: OktaAuthService) {
  }

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

    // Only add to localhost requests since Giphy's API fails when the request include a token
    if (request.url.indexOf('localhost') > -1) {
      request = request.clone({
        setHeaders: {
          Authorization: `Bearer ${this.oktaAuth.getAccessToken().accessToken}`
        }
      });
    }

    return next.handle(request);
  }
}

After you create an interceptor, you’ll need to register it in your app.module.ts:

import { HTTP_INTERCEPTORS } from '@angular/common/http';
import { AuthInterceptor } from './shared/okta/auth.interceptor';

@NgModule({
  ...
  providers: [CarService, GiphyService,
    {provide: HTTP_INTERCEPTORS, useClass: AuthInterceptor, multi: true}
  ],
  ...
})

Thank you very much for you answer and article! They were really useful (perfect i’d say :stuck_out_tongue: since i was working on Spring as well). I am using Gradle 4.5.1 and Kotlin and I have few more questions on this:

  1. I correctly managed to upgrade Spring to 2.0.0.RC1 but when using the 0.2.0 version of your package many errors happen:

    • SLF4J: Class path contains multiple SLF4J bindings.
      SLF4J: Found binding in [jar:file:/C:/Users/lamba/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.2.3/7c4f3c474fb2c041d8028740440937705ebb473a/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
      SLF4J: Found binding in [jar:file:/C:/Users/lamba/.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.25/8dacf9514f0c707cbbcdd6fd699e8940d42fb54e/slf4j-simple-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
      SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
      SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

    • Error processing condition on com.okta.spring.oauth.OktaTokenServicesConfig$LocalTokenValidationConfig.authoritiesExtractor

    When using your 0.1.0 package version, IntelliJ IDEA says to me that okta.oauth.issuer and okta.oauth.clientId “Cannot resolve configuration property” even if it compiles and run correctly (I did not tried to access resources while logged in tho). Here’s my gradle.build file; notice that if i do not add any of your packages the code runs.

  2. In your guide you use Okta’s official Angular SDK while in a previous guide for Angular (the one I used previously) you recommended Manfred Steyer’s project to add OAuth 2 and OpenID. Do you recommend to migrate to the official one? In both yes and no cases, why?


#4

For #1, I’d try upgrading to 0.3.0 or removing DevTools as a depencency.

The answer to #2 is that both will work, but you’ll get better support from us when you use the official Angular SDK.


#5

Uhm, with 0.3.0 it say that RelaxedPropertyResolver class is missing, here’s a GitHub issue with the same problem and here’s the stacktrace:

Process finished with exit code 1

EDIT: Well I managed to solve the multiple SLF4J issue excluding one import from your package (look here for more information):

compile ('com.okta.spring:okta-spring-boot-starter:+') {
		exclude group: 'org.slf4j', module: 'slf4j-simple'
	}

or

compile('org.springframework.boot:spring-boot-starter-web'){
        exclude group: 'ch.qos.logback', module: 'logback-classic'
    }

EDIT 2: I posted the issue on your GitHub project, as bdemers recommended, I rolled back to springBootVersion = '1.5.10.RELEASE' and everything works using:

compile ('com.okta.spring:okta-spring-boot-starter:+') {
		exclude group: 'org.slf4j', module: 'slf4j-simple'
	}
