Laravel Passport回调路由返回null

Question

我正在学习Laravel Passport并开发OAuth2服务器。创建客户端后，我进行了以下调用以获取授权代码

Route::get('/', function (Request $request) {
$request->session()->put('state', $state = Str::random(40));
$query = http_build_query([
'client_id' => <Client_Id>,
'redirect_uri' => 'http://<Consumer_App_URL>/callback',
'response_type' => 'code',
'scope' => '',
'state' => $state,
]);
return redirect('http://<OAuth2_Server_URL>/oauth/authorize?'.$query);
});

调用按预期工作，但当重定向到回调路由时，我得到了授权代码，该路由是这样定义的

Route::get('/callback', function (Request $request) {
$state = $request->session()->pull('state');
throw_unless(
strlen($state) > 0 && $state === $request->state,
InvalidArgumentException::class
);
$response = Http::asForm()->post('http://<OAuth2_Server_URL>/oauth/token', [
'grant_type' => 'authorization_code',
'client_id' => <Client_Id>,
'client_secret' => '<Cient_Secret>',
'redirect_uri' => 'http://consumer/callback',
'code' => $request->code,
]);
return $response->json();
});

它不起作用，响应实例只是空的。我想不出问题出在哪里。

所以我终于解决了问题，我只需要运行php artisan config:cache。【参考文献】
