adUserInfo.setEmail("[email protected]");
return new AdInfo();
}
}
Angular code:
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable, Subject } from 'rxjs';
import { AdInfo } from './ad-info';
@Injectable({
providedIn: 'root'
})
export class LoginService {
private loginUrl: string;
constructor(private http: HttpClient) {
this.loginUrl = 'http://localhost:8080/account';
}
public login(): Observable<AdInfo> {
return this.http.get<AdInfo>(this.loginUrl);
}
}
Angular class:
export class AdInfo {
id: string;
name: string;
email: string;
}
Calling from http://localhost:8080 is working fine. It goes to azure and login . as per • https://docs.microsoft.com/en-us/azure/developer/java/spring-framework/configure-spring-boot-starter-java-app-with-azure-active-directory.
Now i want to call it from Angular UI. So Localhost:4200. made a login page. Onlick login button. It is calling localhost:8080. But error in showing to redirecting to azure ad login.
