Php Laravel多租户作业

遇到作业无法连接到数据库的问题

<?php

namespace App\Jobs;

use Illuminate\Support\Facades\DB;

abstract class Job
{
    protected $account;

    public function start()
    {
        // runs when creating the job, so the config holds the correct value
        $this->account = config('database.connections.tenant.database');
    }

    public function handle()
    {
        // since the handle function runs outside of setting the job 
        // the database is no longer set in the config
        config()->set('database.connections.tenant.database', $this->account);
        // try to force it to reconnect incase it already did for some reason.
        DB::reconnect();
    }
}

目录名称无效：1046未选择数据库

我需要在作业中设置帐户，这样我就有一个扩展类来确保该帐户与作业一起发送，这样我就可以确保数据库可以连接到正确的数据库

<?php

namespace App\Jobs;

use Illuminate\Support\Facades\DB;

abstract class Job
{
    protected $account;

    public function start()
    {
        // runs when creating the job, so the config holds the correct value
        $this->account = config('database.connections.tenant.database');
    }

    public function handle()
    {
        // since the handle function runs outside of setting the job 
        // the database is no longer set in the config
        config()->set('database.connections.tenant.database', $this->account);
        // try to force it to reconnect incase it already did for some reason.
        DB::reconnect();
    }
}

找到了解决这个问题的方法。这并不漂亮，但根据我所看到的情况，laravels队列并不能很好地处理这类事情

首先，我删除了
handle
函数的覆盖，我真正需要的是确保运行队列所需的帐户在作业类上可用

abstract class Job
{
    protected $account;

    public function start()
    {
        // runs when creating the job, so the config holds the correct value
        $this->account = config('database.connections.tenant.database');
    }
}

接下来，我将开关移动到
boot
方法中的
AppServiceProvider
的正确租户数据库

Event::listen(JobProcessing::class, function ($event) {
   if ($payload = $event->job->payload()) {
      preg_match('/"account";s:[0-9]+:"(.*?)"/', $payload['data']['command'], $matches);
      if (count($matches)) {
         if (isset($matches[1])) {
            config()->set('database.connections.tenant.database', $matches[1]);
            config()->set('database.default', 'tenant');
         }
      }
   }
});

我在这里所做的是使用一些正则表达式查看帐户的序列化对象。这里可能会有改进，但到目前为止，在测试中仍然有效。然后在确认帐户后设置正确的数据库

我必须走到这一步的原因是作业在序列化作业本身时进行查询，因此为了传递帐户，需要在序列化作业之前完成查询
