Laravel throttle 如何基于路由限流？

调整App\Providers\RouteServiceProvider@configureRateLimiting，默认是根据IP或者是用户ID限流的，你可以加上路由参数

参考Illuminate\Routing\Middleware\ThrottleRequests@resolveRequestSignature

    /**
     * Resolve request signature.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return string
     *
     * @throws \RuntimeException
     */
    protected function resolveRequestSignature($request)
    {
        if ($user = $request->user()) {
            return sha1($user->getAuthIdentifier());
        } elseif ($route = $request->route()) {
            return sha1($route->getDomain().'|'.$request->ip());
        }

        throw new RuntimeException('Unable to generate the request signature. Route unavailable.');
    }
