Social Login with Angular 5 and Lumen 5.6 - laravel

Question

I am trying to implement social login with angular 5 as my front-end and lumen 5.6 as my backend.
I am using JWT Authentication system with Lumen.
So, I am confused here how I should implement social login system in this situation.
Through my research I have come to these libraries which can do that work, but I am not sure how the process is handled from the front-end (angular) to back-end (lumen).
For Angular 5 -
angularx-social-login OR Satellizer
For Lumen -
laravel/socialite
But as I have not found any documentation on Satellizer working with Angular 5, so I choosed to use other one.
I have read this article, but still the process from front-end to back-end is not clear to me.

Any explanatory help ?

Answer 1

So the way I used social login with Angular 5 is with a package called
"angular5-social-login": "^1.0.9",
So add that to your package.json file.
Import it in app.module.ts
import { SocialLoginModule, AuthServiceConfig, GoogleLoginProvider, FacebookLoginProvider } from 'angular5-social-login';
Set up a function in app.module.ts
export function getAuthServiceConfigs() {
const config = new AuthServiceConfig(
[
{
id: FacebookLoginProvider.PROVIDER_ID,
provider: new FacebookLoginProvider('') // Left as i dont use it
},
{
id: GoogleLoginProvider.PROVIDER_ID,
provider: new GoogleLoginProvider('YOUR-API-TOKEN.apps.googleusercontent.com')
},
]
);
return config;
}
Add it to your Imports in app.module.ts
imports: [
HttpClientModule,
AppRoutingModule,
...
SocialLoginModule, // One we need to add
],
Then at the add it to your providers in app.module.ts
providers: [
YourServices,
...
ApiAuthService,
{
provide: AuthServiceConfig,
useFactory: getAuthServiceConfigs
},
LoggedInGuard,
],
As you can see i have a LoggedInGuard and a ApiAuthService these are these with the auth and checking your logged in.
So That's the package installed and set up...
Now inside of api-auth.service.ts add this function
socialSignIn(userData) {
const formData = new FormData();
formData.append('email', userData.email);
formData.append('name', userData.name);
formData.append('provider', userData.provider);
formData.append('id', userData.id);
formData.append('idToken', userData.idToken);
formData.append('token', userData.token);
formData.append('image', userData.image);
return this._http.post(
environment.apiUrl + '/auth/social-signin/',
formData,
{
headers: new Headers({
'Authorization': 'Bearer ' + userData.idToken
})
}
);
}
Now in your sign in component add this to the HTML
<div (click)="socialSignIn('google')" class="c2a_btn large google">
Log in with google
</div>
In your sign in component .ts file add this function
import { AuthService, FacebookLoginProvider, GoogleLoginProvider, LinkedinLoginProvider } from 'angular5-social-login';
import { ApiAuthService } from '../../../../services/api-auth.service';
import { TokenService } from '../../../../services/token.service';
public socialSignIn(socialPlatform: string) {
this.loading = true;
let socialPlatformProvider;
if (socialPlatform === 'facebook') {
socialPlatformProvider = FacebookLoginProvider.PROVIDER_ID;
} else if (socialPlatform === 'google') {
socialPlatformProvider = GoogleLoginProvider.PROVIDER_ID;
} else if (socialPlatform === 'linkedin') {
socialPlatformProvider = LinkedinLoginProvider.PROVIDER_ID;
}
this.socialAuthService.signIn(socialPlatformProvider).then(
(userData) => {
this._apiAuthService.socialSignIn(userData)
.map( data => {
return data.json();
})
.subscribe(
token => {
this._tokenService.setAccessToken(token.access_token);
},
error => {
this.invalidLogin = true;
this.loading = false;
},
() => {
this.loading = false;
this.closeSignIn.emit('out');
// this._router.navigate(['/profile']);
}
);
}
);
}
This is just the front end now for the back end. I'm using Laravel 5.6
But I made a function like this
public function socialSignIn(Request $request, Response $response) {
$date = date('Y-m-d h:i:s');
$provider = $request->input('provider');
if ($provider == 'google') {
$id_token = $request->header('Authorization');
$id_token = str_replace("Bearer ","",$id_token);
$CLIENT_ID = Config::get('google.client_id');
$email = $request->input('email');
$names = $request->input('name');
$name = explode(' ', $names);
$client = new \Google_Client();
$client->setDeveloperKey($CLIENT_ID);
$payload = $client->verifyIdToken($id_token);
if ($payload) {
if (User::where('email', '=', $email)->exists()) {
$user = User::Where('email', '=', $email)->first();
if(!Auth::loginUsingId($user->id)){
return response()->json([
'failed'
], 403);
}
$updateLastLoginDate = User::where('id', Auth::user()->id)-first();
$updateLastLoginDate->last_login_date = $date;
$updateLastLoginDate->save();
$activeAccount = Auth::user();
$activeAccount->active = '1';
$activeAccount->save();
} else {
$recordUser = New User;
$recordUser->email = $request->input('email');
$recordUser->last_login_date = $date;
$recordUser->save();
$recordLinkedSocialAcounts = new LSA;
$recordLinkedSocialAcounts->user_id = $recordUser->id;
$recordLinkedSocialAcounts->provider_name = $provider;
$recordLinkedSocialAcounts->provider_id = $request->input('id');
$recordLinkedSocialAcounts->save();
$recordUserInformation = new UPI;
$recordUserInformation->user_id = $recordUser->id;
$recordUserInformation->first_name = $name[0];
$recordUserInformation->last_name = $name[1];
$recordUserInformation->last_login_date = $date;
$recordUserInformation->image = $request->input('image');
$recordUserInformation->save();
if(!Auth::loginUsingId($recordUser->id)){
return response()->json([
'failed'
], 403);
}
}
return response()->json([
'access_token' => Auth::user()->createToken('access_token')->accessToken,
'role_id' => Auth::user()->role_id
], 200);
} else {
return response()->json([
'failed'
], 403);
}
}
}
I will most probably make a video on this soon. Any questions just ask
