Laravel throttle 如何基于路由限流？

– 自己重新写一个基于路由限流的中间件即可
– 把resolveRequestSignature方法重写下即可

<?php

namespace App\Http\Middleware;

use Illuminate\Routing\Middleware\ThrottleRequests as Middleware;
use RuntimeException;
use Closure;

class ThrottleRouteRequests extends Middleware
{
    /**
     * 不限制访问频率的路由
     *
     * @var array
     */
    protected $except = [

    ];

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  int|string  $maxAttempts
     * @param  float|int  $decayMinutes
     * @return mixed
     * @throws \Symfony\Component\HttpKernel\Exception\HttpException
     */
    public function handle($request, Closure $next, $maxAttempts = 60, $decayMinutes = 1)
    {
        $route = $request->route();
        if (in_array($route->getName(), $this->except)) {
            return $next($request);
        }

        return parent::handle($request, $next, $maxAttempts, $decayMinutes);
    }

    /**
     * Resolve request signature.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return string
     * @throws \RuntimeException
     */
    protected function resolveRequestSignature($request)
    {
        $user = $request->user();
        $route = $request->route();

        //单个路由访问频率限制
        if ($user && $route) {
            return $route->getName().'|'.sha1($user->getAuthIdentifier());
        }

        if ($route) {
            return sha1($route->getName().'|'.$route->getDomain().'|'.$request->ip());
        }

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

throttle功能是由 Illuminate\Routing\Middleware\ThrottleRequests类实现的

查看那个类会发现有一个叫fingerprint的函数

是定义Request的规则的地方

把这个部分改了就可以

当然不建议直接改这个文件，因为这个是Laravel vendor文件夹里面的，

建议继承这个类，新造一个中间件类，重写fingerprint函数的相关逻辑，然后把这个中间件注册到需要的router上就行了
