Giving Lumen's Google Login Email from Vue.js

Google Auth Integration with Vue.js and Lumen

Using Axios and Lumen API with Vue.js

import { googleSdkLoaded } from "vue3-google-login";
import axios from "axios";
export default {
  name: "App",
  data() {
    return { userDetails: null };
  },
  methods: {
    login() {
      googleSdkLoaded(google => {
        google.accounts.oauth2.initCodeClient({
          client_id: "YOUR_CLIENT_ID",
          scope: "email profile openid",
          redirect_uri: "http://localhost:8000/api/Google_login",
          callback: response => {
            if (response.code) {
              this.sendCodeToBackend(response.code, response.email);
            }
          }
        }).requestCode();
      });
    },
    async sendCodeToBackend(code, email) {
      try {
        const headers = { Authorization: code, Email: email };
        const response = await axios.post("http://localhost:8000/api/Google_login", null, { headers });
        this.userDetails = response.data;
      } catch (error) {
        console.error("Failed to send authorization code:", error);
      }
    }
  }
};

Implementation of Lumen Backend for JWT Authentication

PHP with Lumen Framework

<?php
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\Support\Facades\Auth;
public function Google_login(Request $request) {
  try {
    $user = User::where('email', $request->email)->first();
    if ($user) {
      $token = Auth::login($user);
      return response()->json(['token' => $token]);
    } else {
      return response()->json(['message' => 'Email is not registered'], 401);
    }
  } catch (\Throwable $th) {
    return response()->json(['status' => false, 'message' => $th->getMessage()], 500);
  }
}?>

Frequently Asked Questions about Lumen Google Authentication with Vue.js

1. How should I safely save the tokens I got from Google?
2. Make sure your backend verifies the signature of the token to confirm its integrity and use secure, HTTP-only cookies.
3. How does the OAuth 2.0 flow operate and what is it?
4. A protocol known as the OAuth 2.0 flow enables a user to give access to information held by a third-party website or application without disclosing their login credentials.
5. How can I use Google Login to manage user sessions in Vue.js?
6. Utilize the OAuth token you were given to store and send authenticated requests to your backend with in order to manage sessions.
7. Why do I keep getting the message "Email not registered"?
8. This issue usually appears when your database does not contain the email that was obtained through the OAuth process. Make sure you appropriately manage both new and returning users.
9. Which security best practices apply to OAuth implementations?
10. The use of HTTPS for all connections, safe token storage, and the addition of a state parameter to OAuth requests to thwart CSRF attacks are examples of best practices.

Concluding Remarks on Integrating Google Authentication with Vue.js and Lumen

The seamless integration of Google authentication with Vue.js and Lumen web apps improves user security and expedites the login procedure. By utilizing Google's strong security infrastructure, developers may lower the likelihood of data breaches. A complete grasp of every stage in the OAuth process is crucial to ensuring a flawless user experience and protecting user information from unwanted access. Accurate implementation and error management are also crucial.
