我们正在尝试访问当前登录用户的 id，我们以这种方式修改了 auth.php 文件：
'api' => [
'driver' => 'session',
'provider' => 'users',
],
在此之后我们还编辑了 Kernel.php 文件：
'api' => [
'throttle:60,1',
'bindings',
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
在我们的 Route api.php 我们有这个：
Auth::routes();
Route::middleware('api')->group(function(){
Route::post('/tipo', [App\Http\Controllers\ApiController::class, 'createtipo']);
Route::post('/corso', [App\Http\Controllers\ApiController::class, 'createcorso']);
Route::get('/mostracorsi', [App\Http\Controllers\ApiController::class, 'mostracorsi']);
Route::get('/mostracorso/{idCorso}', [App\Http\Controllers\ApiController::class, 'mostracorso']);
Route::put('/updatecorso/{idCorso}', [App\Http\Controllers\ApiController::class, 'updatecorso']);
Route::delete('/deletecorso/{idCorso}', [App\Http\Controllers\ApiController::class, 'deletecorso']);
Route::post('/iscrizione', [App\Http\Controllers\ApiController::class, 'iscrizione']);
Route::get('/vedicorso/{idCorso}', [App\Http\Controllers\ApiController::class, 'vedicorso']);
Route::delete('/deleteiscrizione/{idUtente}', [App\Http\Controllers\ApiController::class, 'deleteiscrizione']);
Auth::routes();
}));
在我们的控制器中我们有这个：
public function createcorso(Request $request)
{
$corsoscii = new CorsoScii();
$admin_id = new AdminController();
$corsoscii->tipo = $request->input('tipo');
$corsoscii->nome = $request->input('nome');
$corsoscii->membriMax = $request->input('membriMax');
$corsoscii->orario_inizio = $request->input('orario_inizio');
$corsoscii->orario_fine = $request->input('orario_fine');
$corsoscii->inizio = $request->input('inizio');
$corsoscii->fine = $request->input('fine');
$corsoscii->save();
$idUtente = Auth::id();
$idCorso = CorsoScii::latest()->first();
DB::table('iscrizione')->insert(
array('idUtente' => $idUtente, 'idCorso' => $idCorso)
);
return response()->json($corsoscii);
}
我们之所以选择这种方式，是因为每次我们在控制器上传递当前用户 id 时，它总是为空：
SQLSTATE [23000]：违反完整性约束：1048 列 'idUtente' 不能为空
当我们再次尝试执行 ajax 调用时，它会在浏览器控制台中显示以下错误：
未找到绑定异常目标类
如果可能是有用的信息，我们也有路线列表，我们试图了解这里有什么问题：
