Question

我正在尝试创建一个服务，该服务接收.env文件中定义的两个参数。

Symfony抛出下一个错误：

无法自动连线服务   “ App \ Modules \ Sales \ Infrastructure \ Persistence \ Http \ HttpSalesRepository”：   方法“ __construct（）”的参数“ $ credentials”的类型为“ ar
  ray”，则应明确配置其值。

这是我的service.yml文件：

parameters:

services:
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

    App\Controller\:
        resource: '../src/Controller'
        tags: ['controller.service_arguments']

imports:
    - { resource: "../src/Modules/Sales/Infrastructure/DependencyInjection/sales_module.yml" }

这是sales_module.yml中的代码：

services:
  module_sales.http.sales.repository:
    public: false
    class: App\Modules\Sales\Infrastructure\Persistence\Http\HttpSalesRepository
    arguments: ["%env(json:CREDENTIALS)%", "%env(json:TAGS)%"]

这是HttpSalesRepository类

class HttpSalesRepository implements SalesRepository
{
    private $credentials;
    private $tags;

    public function __construct(array $credentials, array $tags)
    {
        $this->credentials = $credentials;
        $this->tags = $tags;
    }
    ...
 }

这是.env文件：

###> symfony/framework-bundle ###
APP_ENV=dev
APP_SECRET=xxxxxx
###< symfony/framework-bundle ###

###> doctrine/doctrine-bundle ###
DATABASE_URL=mysql://xxx:yyy@mysql:3306/db
###< doctrine/doctrine-bundle ###

###> application/variables ###
CREDENTIALS='{"username":"email@test.com","password":"secretpass"}'
TAGS='["tag1","tag2","tag3"]'
###< application/variables ###

有什么想法吗？

Answer 1

您可以命名服务参数以使参数名称与值显式匹配，而不仅仅是参数列表：

services:
  module_sales.http.sales.repository:
    public: false
    class: App\Modules\Sales\Infrastructure\Persistence\Http\HttpSalesRepository
    arguments: 
      $credentials: "%env(json:CREDENTIALS)%"
      $tags: "%env(json:TAGS)%"]

Answer 2

这不是最佳选择，但是当我找到最终解决方案时，这是一项工作。如果我在config / services.yaml中定义服务，则变量将完美地传递到服务。

App\Modules\Sales\Infrastructure\Persistence\Http\HttpSalesRepository:
    public: false
    arguments: ["%env(json:AMAZON_AFFILIATES_CREDENTIALS)%", "%env(json:AMAZON_AFFILIATES_TAGS)%"]

任何其他解决方案都将受到欢迎。
