jwt authentication laravel react code example
Example 1: laravel token authentication
# Database Preparation
// add api_token to users table
Schema::table('users', function ($table) {
$table->string('api_token', 80)->after('password')
->unique()
->nullable()
->default(null);
});
// Create token for existing users, code can also be added to registerController
$token = Str::random(60);
$user = User::find(1);
$user->api_token = hash('sha256', $token); // <- This will be used in client access
$user->save();
//config/auth.php
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token', // <- Add this entry
'provider' => 'users',
'hash' => false,
],
],
//routes/api.php
// Add "middleware('auth:api')" as below
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
//client access example (in Vue js)
axios.get('http://example.com/api/user',
{
headers: {
'Accept': 'application/json',
'Authorization': 'Bearer '+ 'user-api-token'
}
}
)
.then(function (response) {
// handle success
console.log(response);
})
.catch(function (error) {
// handle error
console.log(error);
})
Example 2: vanilla javascript jwt authentication laravel
In my guest RedirectIfAuthenticated middleware check for cookie, if exists, setToken which in turn sets Guard to Authenticated and will always redirect to /home if token is available and valid:
public function handle($request, Closure $next, $guard = null)
{
if ($request->hasCookie('access_token')) {
Auth::setToken($request->cookie('access_token'));
}
if (Auth::guard($guard)->check()) {
return redirect('/home');
}
return $next($request);
}
And In my post-auth Routes middleware I also setToken and if its valid and exists, will allow access, otherwise will throw a range of JWT errors which just redirect to pre-auth view:
public function handle($request, Closure $next)
{
JWTAuth::setToken($request->cookie('access_token'))->authenticate();
return $next($request);
}
