MSAL Angular-konfiguration

MSAL för Angular kan konfigureras på flera sätt. Den här artikeln beskriver tillgängliga konfigurationsalternativ för MSAL Angular, inklusive statiska och dynamiska metoder, och innehåller kodexempel för integrering av autentisering i din app. Använd den här guiden för att välja den konfigurationsmetod som bäst passar programmets krav och ger användarna en smidig inloggningsupplevelse.

Konfigurationsalternativ

@azure/msal-angular accepterar tre konfigurationsobjekt:

Konfiguration: Det här är samma konfigurationsobjekt som används för kärnbiblioteket @azure/msal-browser . Alla konfigurationsalternativ finns här.
MsalGuardConfiguration: En uppsättning alternativ specifikt för Angular Guard.
MsalInterceptorConfiguration: En uppsättning alternativ specifikt för Angular-interceptorn.

Konfigurationer specifika för Angular

Ett interactionType måste anges på MsalGuardConfiguration och MsalInterceptorConfiguration, och kan anges till Popup eller Redirect.
Objektet protectedResourceMap på MsalInterceptorConfiguration används för att skydda vägar.
Ett valfritt authRequest objekt kan anges på MsalGuardConfiguration och MsalInterceptorConfiguration för att ange ytterligare alternativ.
En valfri loginFailedRoute sträng kan ställas in på MsalGuardConfiguration. Msal Guard omdirigerar till den här rutten om inloggning krävs men misslyckas.

Mer information om konfigurationer, användning och skillnader med MSAL Angular v1 finns i dokumentationen om MsalInterceptor och MsalGuard .

Konfiguration för omdirigeringar

Vi rekommenderar att du importerar MsalRedirectComponent och startar med AppComponent om du tänker använda omdirigeringar. Mer information finns i omdirigeringsdokumentationen .

Observera: Från och med MSAL v3.x krävs nu initiering av programobjektet. Mer information finns i uppgraderingsguiden för v2-v3 . Mer information om hur du uppgraderar till MSAL Angular v5 finns i uppgraderingsguiden för v4-v5.

MsalModule.forRoot

Klassen MsalModule innehåller en statisk metod som kan anropas i filen app.module.ts :

import { NgModule } from "@angular/core";
import { HTTP_INTERCEPTORS } from "@angular/common/http";
import { AppComponent } from "./app.component";
import { MsalModule, MsalService, MsalGuard, MsalInterceptor, MsalBroadcastService, MsalRedirectComponent } from "@azure/msal-angular";
import { PublicClientApplication, InteractionType, BrowserCacheLocation } from "@azure/msal-browser";

@NgModule({
  imports: [
    MsalModule.forRoot(
      new PublicClientApplication({
        // MSAL Configuration
        auth: {
          clientId: "clientid",
          authority: "https://login.microsoftonline.com/common/",
          redirectUri: "http://localhost:4200/",
          postLogoutRedirectUri: "http://localhost:4200/",
        },
        cache: {
          cacheLocation: BrowserCacheLocation.LocalStorage,
        },
        system: {
          loggerOptions: {
            loggerCallback: () => {},
            piiLoggingEnabled: false,
          },
        },
      }),
      {
        interactionType: InteractionType.Popup, // MSAL Guard Configuration
        authRequest: {
          scopes: ["user.read"],
        },
        loginFailedRoute: "/login-failed",
      },
      {
        interactionType: InteractionType.Redirect, // MSAL Interceptor Configuration
        protectedResourceMap,
      }
    ),
  ],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: MsalInterceptor,
      multi: true,
    },
    MsalGuard,
  ],
  bootstrap: [AppComponent, MsalRedirectComponent],
})
export class AppModule {}

Fabriksleverantörer

Du kan också ange konfigurationsalternativen via fabriksprovidrar.

import { MsalModule, MsalService, MsalInterceptor, MsalInterceptorConfiguration, MsalGuard, MsalGuardConfiguration, MsalBroadcastService, MsalRedirectComponent } from "@azure/msal-angular";
import { IPublicClientApplication, PublicClientApplication, InteractionType, BrowserCacheLocation } from "@azure/msal-browser";

export function MSALInstanceFactory(): IPublicClientApplication {
  return new PublicClientApplication({
    auth: {
      clientId: "00001111-aaaa-2222-bbbb-3333cccc4444",
      redirectUri: "http://localhost:4200",
      postLogoutRedirectUri: "http://localhost:4200",
    },
    cache: {
      cacheLocation: BrowserCacheLocation.LocalStorage,
    },
  });
}

export function MSALInterceptorConfigFactory(): MsalInterceptorConfiguration {
  const protectedResourceMap = new Map<string, Array<string>>();
  protectedResourceMap.set("https://graph.microsoft.com/v1.0/me", ["user.read"]);

  return {
    interactionType: InteractionType.Redirect,
    protectedResourceMap,
  };
}

export function MSALGuardConfigFactory(): MsalGuardConfiguration {
  return {
    interactionType: InteractionType.Redirect,
    authRequest: {
      scopes: ["user.read"],
    },
    loginFailedRoute: "./login-failed",
  };
}

@NgModule({
  imports: [MsalModule],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: MsalInterceptor,
      multi: true,
    },
    {
      provide: MSAL_INSTANCE,
      useFactory: MSALInstanceFactory,
    },
    {
      provide: MSAL_GUARD_CONFIG,
      useFactory: MSALGuardConfigFactory,
    },
    {
      provide: MSAL_INTERCEPTOR_CONFIG,
      useFactory: MSALInterceptorConfigFactory,
    },
    MsalGuard,
    MsalBroadcastService,
    MsalService,
  ],
  bootstrap: [AppComponent, MsalRedirectComponent],
})
export class AppModule {}

platformBrowserDynamic

Om du behöver konfigurera MSAL Angular dynamiskt (t.ex. baserat på värden som returneras från ett API) kan du använda platformBrowserDynamic. platformBrowserDynamic är en plattformsfabrik som används för att starta applikationen och kan ta emot konfigurationsalternativ. platformBrowserDynamic bör redan finnas när Angular-programmet har konfigurerats.

Följande är ett exempel på hur du konfigurerar dynamiskt @azure/msal-angular med platformBrowserDynamic och en json-fil:

app.module.ts

import { MsalModule, MsalInterceptor, MsalService } from "@azure/msal-angular";

@NgModule({
  imports: [MsalModule],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: MsalInterceptor,
      multi: true,
    },
    MsalService,
  ],
  bootstrap: [AppComponent],
})
export class AppModule {}

main.ts

import { enableProdMode } from "@angular/core";
import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";

import { AppModule } from "./app/app.module";
import { environment } from "./environments/environment";
import { MSAL_INSTANCE, MSAL_GUARD_CONFIG, MSAL_INTERCEPTOR_CONFIG } from "@azure/msal-angular";
import { PublicClientApplication, Configuration } from "@azure/msal-browser";

if (environment.production) {
  enableProdMode();
}

function loggerCallback(logLevel: LogLevel, message: string) {
  console.log("MSAL Angular: ", message);
}

fetch("/assets/configuration.json")
  .then((response) => response.json())
  .then((json) => {
    platformBrowserDynamic([
      {
        provide: MSAL_INSTANCE,
        useValue: new PublicClientApplication({
          auth: json.msal.auth,
          cache: json.msal.cache,
          system: {
            loggerOptions: {
              loggerCallback,
              logLevel: LogLevel.Info,
              piiLoggingEnabled: false,
            },
          },
        }),
      },
      {
        provide: MSAL_GUARD_CONFIG,
        useValue: {
          interactionType: json.guard.interactionType,
          authRequest: json.guard.authRequest,
          loginFailedRoute: json.guard.loginFailedRoute,
        } as MsalGuardConfiguration,
      },
      {
        provide: MSAL_INTERCEPTOR_CONFIG,
        useValue: {
          interactionType: json.interceptor.interactionType,
          protectedResourceMap: new Map(json.interceptor.protectedResourceMap),
        } as MsalInterceptorConfiguration,
      },
    ])
      .bootstrapModule(AppModule)
      .catch((err) => console.error(err));
  });

src/assets/configuration.json

  "msal": {
    "auth": {
      "clientId": "clientid",

      "navigateToLoginRequestUrl": true
    },
    "cache": {
      "cacheLocation": "localStorage",
      "storeAuthStateInCookie": true
    }
  },

Dynamiska konfigurationer med hjälp av fabriksprovidrar och APP_INITIALIZER

Om du vill konfigurera MSAL Angular dynamiskt kan du använda Fabriksprovidrar med APP_INITIALIZER.

src/app/config.service.ts

import { Injectable } from "@angular/core";
import { HttpClient, HttpBackend } from "@angular/common/http";
import { map } from "rxjs/operators";

@Injectable({
  providedIn: "root",
})
export class ConfigService {
  private settings: any;
  private http: HttpClient;

  constructor(private readonly httpHandler: HttpBackend) {
    this.http = new HttpClient(httpHandler);
  }

  init(endpoint: string): Promise<boolean> {
    return new Promise<boolean>((resolve, reject) => {
      this.http
        .get(endpoint)
        .pipe(map((result) => result))
        .subscribe(
          (value) => {
            this.settings = value;
            resolve(true);
          },
          (error) => {
            reject(error);
          }
        );
    });
  }

  getSettings(key?: string | Array<string>): any {
    if (!key || (Array.isArray(key) && !key[0])) {
      return this.settings;
    }

    if (!Array.isArray(key)) {
      key = key.split(".");
    }

    let result = key.reduce((account: any, current: string) => account && account[current], this.settings);

    return result;
  }
}

src/app/msal-config-dynamic.module.ts

import { InjectionToken, NgModule, APP_INITIALIZER } from "@angular/core";

MsalGuard – begäran om dynamisk autentisering

MsalGuard gör det också möjligt för dig att dynamiskt ändra authRequest under körning. Detta gör det möjligt att välja en annan auktoritet för en rutt eller att dynamiskt lägga till scope:ar baserat på RouterStateSnapshot.

export function MSALGuardConfigFactory(): MsalGuardConfiguration {
  return {
    interactionType: InteractionType.Redirect,
    authRequest: (authService, state) => {
      return {
        scopes: state.root.url.some((x) => x.path === "calendar") ? ["user.read", "	Calendars.Read"] : ["user.read"],
      };
    },
    loginFailedRoute: "./login-failed",
  };
}

Konfigurationer för Angular-appar med fristående komponenter

Angular-applikationer som använder fristående komponenter kan använda fabriksleverantörer enligt ovan i filen app.config.ts, som sedan importeras till main.ts för uppstart.
