class RouteServiceProvider extends ServiceProvider
{
   .
   .
   .
   .
   .
   protected $namespace ='App\Http\Controllers';
  public  function boot()
   {
         $this->configureRateLimiting();
         $this->routes(function () {
            Route::middleware('api')
                ->prefix('api')
                ->namespace($this->namespace)
                ->group(base_path('routes/api.php'));
            Route::middleware('web')
            ->namespace($this->namespace)
            ->group(base_path('routes/web.php'));
        });
    }
}

<?php
use IlluminateHttpRequest;
use IlluminateSupportFacadesRoute;
//use AppHttpControllersApiCaptchasController;
Route::prefix('v1')
    ->name('api.v1.')
    ->namespace("Api")//添加命名空间
    ->group(function () {
         Route::middleware('throttle:'.
         config('api.rate_limits.sign'))
        ->group(function () {
           // Route::post('captchas', [CaptchasController::class, 'store'])->name('captchas.store'); ---原来的
              Route::post('captchas', 'CaptchasController@store')
              ->name('captchas.store');// 修改成这样即可
     });
           Route::middleware('throttle:' .config('api.rate_limits.access'))
            ->group(function () {
            });
    })
