I have a Single Page App (SPA) written in ReactJS. I am attempting to query the Graph API. I am using the msal.js library to handle my authentication. I am using Azure AD B2C to manage my accounts. What I have so far:
I am able to login to Google and get my profile information back to my SPA. However, when an accessToken is requested, the result is empty. I am positive I'm doing something wrong and I'm guessing it's around my app registration and scopes. When I registered my app, it had a default scope called "user_impersonation". As I type this, I realize I registered my client (SPA) and not the API. Do I need to register both? I'm not sure how I would register Graph.
My code:
App.js
import AuthService from '../services/auth.service';
import GraphService from '../services/graph.service';
class App extends Component {
constructor() {
super();
this.authService = new AuthService();
this.graphService = new GraphService();
this.state = {
user: null,
userInfo: null,
apiCallFailed: false,
loginFailed: false
};
}
componentWillMount() {}
callAPI = () => {
this.setState({
apiCallFailed: false
});
this.authService.getToken().then(
token => {
this.graphService.getUserInfo(token).then(
data => {
this.setState({
userInfo: data
});
},
error => {
console.error(error);
this.setState({
apiCallFailed: true
});
}
);
},
error => {
console.error(error);
this.setState({
apiCallFailed: true
});
}
);
};
logout = () => {
this.authService.logout();
};
login = () => {
this.setState({
loginFailed: false
});
this.authService.login().then(
user => {
if (user) {
this.setState({
user: user
});
} else {
this.setState({
loginFailed: true
});
}
},
() => {
this.setState({
loginFailed: true
});
}
);
};
render() {
let templates = [];
if (this.state.user) {
templates.push(
<div key="loggedIn">
<button onClick={this.callAPI} type="button">
Call Graph's /me API
</button>
<button onClick={this.logout} type="button">
Logout
</button>
<h3>Hello {this.state.user.name}</h3>
</div>
);
} else {
templates.push(
<div key="loggedIn">
<button onClick={this.login} type="button">
Login with Google
</button>
</div>
);
}
if (this.state.userInfo) {
templates.push(
<pre key="userInfo">{JSON.stringify(this.state.userInfo, null, 4)}</pre>
);
}
if (this.state.loginFailed) {
templates.push(<strong key="loginFailed">Login unsuccessful</strong>);
}
if (this.state.apiCallFailed) {
templates.push(
<strong key="apiCallFailed">Graph API call unsuccessful</strong>
);
}
return (
<div className="App">
<Header />
<Main />
{templates}
</div>
);
}
}
export default App
auth.service.js:
import * as Msal from 'msal';
export default class AuthService {

// let PROD_REDIRECT_URI = 'https://sunilbandla.github.io/react-msal-sample/';

this.applicationConfig = {

this.app = new Msal.UserAgentApplication(this.applicationConfig.clientID, this.applicationConfig.authority, function (errorDesc, token, error, tokenType) {});
// this.logger = new Msal.logger(loggerCallback, { level: Msal.LogLevel.Verbose, correlationId:'12345' });
}
login = () => {
return this.app.loginPopup(this.applicationConfig.b2cScopes).then(
idToken => {
const user = this.app.getUser();
if (user) {
return user;
} else {
return null;
}
},
() => {
return null;
}
);
};
logout = () => {
this.app.logout();
};
getToken = () => {
return this.app.acquireTokenSilent(this.applicationConfig.b2cScopes).then(
accessToken => {
return accessToken;
},
error => {
return this.app
.acquireTokenPopup(this.applicationConfig.b2cScopes)
.then(
accessToken => {
return accessToken;
},
err => {
console.error(err);
}
);
}
);
};
}
graph.service.js
export default class GraphService {
constructor() {
// this.graphUrl = 'https://graph.microsoft.com/v1.0';
this.graphUrl = 'http://httpbin.org/headers';
}
getUserInfo = token => {
const headers = new Headers({ Authorization: `Bearer ${token}` });
const options = {
headers
};
return fetch(`${this.graphUrl}`, options)
.then(response => response.json())
.catch(response => {
throw new Error(response.text());
});
};
}
I was getting an access denied error when trying to query the Graph API so I replaced graph.microsoft.com/1.0 with httpbin so I could actually see what was being passed in. This is where I saw that the token was null. This is the exact same code I pulled from Microsoft's example project, which works when I use their code. What they don't show is how AAD B2C and app registrations are configured which is where I believe my problem is.
