763 2022-11-02 16:53:08

Laravel 团队本周发布了 9.38 。这些更新包括单例 artisan 命令,条件性设置 notification 通知中间件,queueable 通知可配置最大异常数,等等。

Today's Laravel 9.38.0 release introduces Isolatable commands. Ensure that only one instance of an Artisan command is running at a time. ⌛

A cinch to use - and we've added support for this to the "migrate" command already. Handy during deployment!

单例 Artisan 命令

Oliver Nybroe 贡献了 Isolatable 接口,让你的命令一次只运行一个进程变得非常容易。 

namespace App\Console\Commands;
 
use Illuminate\Console\Command;
use Illuminate\Contracts\Console\Isolatable;
 
class SendEmails extends Command implements Isolatable
{
    // ...
}-

引入 Isolatatable 接口的首个 artisan 命令是 artisan migrate 命令。使用 --isolated 标志你可以限制将 migrate 限制在一个激活的进程中,确保不会出现两个服务同时运行 migrate 命令这样的情况:

php artisan migrate --isolated

注意:migrate 中的 isolated 不是默认的情况,需要使用 --isolated 以减少产生破坏性改变的可能。

设置 session 保存的 handler

Samuel Štancl 贡献了 setHandler 方法给 session Store 类。PR 描述说明了这一方法的用处:

The use case is that when you're changing database connections on the fly, the database session driver can run into issues where it tries to run queries on a DB connection that no longer exists...By adding the setter, I can reconstruct the DatabaseSessionHandler on the fly and make it use the correct DB connection.

Slug 助手词典

贡献者@Dhemy :在调用 Str::slug() 时,可为指定字符自定义字典:

$ php artisan tinker
 
>>> Str::slug('500$ bill');
=> "500-bill"
 
>>> Str::slug(
...     title: '500$ bill',
...     dictionary: ['@' => 'at', '$' => 'dollar']
... );
=> "500-dollar-bill"

条件性设置通知中间件 

Andrew Monty 贡献了基于notifiable 和 channel 实例对通知中间件进行设置的能力。PR 中的示例:

public function middleware($notifiable, $channel)
{
    if ($notifiable instance of User && $notifiable->isAdmin()) {
        return [];
    }
 
    if ($channel == 'email') {
        return [new RateLimited('mailgun')];
    }
 
    return [];
}

添加 touchQuietly 模型快捷方法

Craig Anderson 贡献了 touchQuietly() 快捷方法,用以在不触碰事件的情况下可以接触到 update 时间戳:

$model->touchQuietly();

从 group 中移除中间件

贡献者Mateus Guimarães 。该特性可用于动态注册或移除中间件。

$router->removeMiddlewareFromGroup(
    'web',
    'test-middleware'
);

Queueable notifications 可以设置最大 exceptions 数

Andrew Monty contributed the ability for queued notifications to use max exceptions. Setting max exceptions is helpful in a setting where you have many retries. Perhaps the queued notification is rate limited by a third party or otherwise not going to succeed, and you want to customize the max number of allowed exceptions.

See Pull Request #44773 for more details and examples.
