Laravel 5：雄辩的选择+在Nginx / Apache上返回错误502

Question

I have the following request:

            $orders = OrderHeader
            ->with('status')
            ->select('id')
            ->get();

And it returns 502 Bad gateway on nginx+php-fpm and ERR_EMPTY_RESPONSE on apache2.

If I remove either 'with' or 'select' everything works good.

I've already performed the regular operations such as restarting nginx and php-fpm, reinstalling the php-fpm, changing some fastcgi parameters in nginx config - all these actions didn't help.

The nginx error log shows '104 Connection reset by peer' and there's nothing in php log.

Any ideas?

Seems that what you really want is this:

$orders = OrderHeader->with('status')->lists('id');

No need to try to select the column off of the table. If for some reason you need more control, then use a closure to filter the query accordingly:

$orders = OrderHeader->with(['status' => function($query){
    return $query->select('id');
}])->get();

This should resolve your issue.
