Laravel 队列速率限制或节流 [英] Laravel queue rate limiting or throttling

问题描述

我正在开发一个需要从第三方服务器获取数据的应用程序，该服务器每秒最多允许 1 个请求.

I am working on an app that requires fetching data from a third-party server and that server allows max 1 request per seconds.

现在，所有请求都作为作业发送，我正在尝试实施 Laravel "速率限制" 每秒发布 1 个作业，但无法弄清楚为什么要实现它，而且网络上没有真实的例子.

Now, all request send as job and I am trying to implement Laravel "Rate Limiting" to release 1 job per second but unable to figure out why it should be implemented and there is no real-life example in the web.

有人实施了吗?

有任何暗示吗?

推荐答案

我是 mxl/laravel-queue-rate-limit Composer 包.

I'm the author of mxl/laravel-queue-rate-limit Composer package.

它允许您在不使用 Redis 的情况下对特定队列上的作业进行速率限制.

It allows you to rate limit jobs on specific queue without using Redis.

1. 安装:

$ composer require mxl/laravel-queue-rate-limit:^1.0

此包与 Laravel 5.5+ 兼容并使用 自动发现 功能将 MichaelLedinLaravelQueueRateLimitQueueServiceProvider::class 添加到提供程序.

This package is compatible with Laravel 5.5+ and uses auto-discovery feature to add MichaelLedinLaravelQueueRateLimitQueueServiceProvider::class to providers.

向config/queue.php添加速率限制设置:

'rateLimit' => [
    'mail' => [
        'allows' => 1,
        'every' => 5
    ]
]

这些设置允许在 mail 队列上每 5 秒运行 1 个作业.确保默认队列驱动程序(config/queue.php 中的 default 属性)设置为除 sync 之外的任何值.

These settings allow to run 1 job every 5 seconds on mail queue. Make sure that default queue driver (default property in config/queue.php) is set to any value except sync.

使用 --queue mail 选项运行队列工作器:

Run queue worker with --queue mail option:

$ php artisan queue:work --queue mail

您可以在多个队列上运行工作程序，但只有在 rateLimit 设置中引用的队列才会受到速率限制:

You can run worker on multiple queues, but only queues referenced in rateLimit setting will be rate limited:

$ php artisan qeueu:work --queue mail,default

default 队列上的作业将在没有速率限制的情况下执行.

Jobs on default queue will be executed without rate limiting.

将一些作业排队以测试速率限制:

Queue some jobs to test rate limiting:

SomeJob::dispatch()->onQueue('mail');
SomeJob::dispatch()->onQueue('mail');
SomeJob::dispatch()->onQueue('mail');
SomeJob::dispatch();
