Braintree dropin UI - 需要将访问令牌传递给 Braintree\\Gateway

Question

带有 Braintree JS 嵌入式 UI 的 Symfony 4 应用程序

我创建了一个名为 Braintree 的服务来开始测试。

namespace App\Services;

use Braintree\ClientToken;


class Braintree
{

    // environment variables:
    const ENVIRONMENT = 'BRAINTREE_ENVIRONMENT';
    const MERCHANT_ID = 'BRAINTREE_MERCHANT_ID';
    const PUBLIC_KEY = 'BRAINTREE_PUBLIC_KEY';
    const PRIVATE_KEY = 'BRAINTREE_PRIVATE_KEY';

    /** @var \Braintree_Gateway */
    private $gateway;

    function __construct() {
        $gateway = new \Braintree_Gateway([
            'environment' => getenv(self::ENVIRONMENT),
            'merchantId' => getenv(self::MERCHANT_ID),
            'publicKey' => getenv(self::PUBLIC_KEY),
            'privateKey' => getenv(self::PRIVATE_KEY)
        ]);
    }

public function generate() {
    return ClientToken::generate();
}

我收到以下错误：

HTTP 500 Internal Server Error
Braintree\Configuration::merchantId needs to be set (or accessToken needs to be passed to Braintree\Gateway).

BT 配置已正确输入到 .env 文件中。 为什么不设置 MERCHANT_ID？

编辑：

添加配置

Braintree_Gateway:
    class: Braintree_Gateway
    arguments:
        -
          'environment': '%env(BRAINTREE_ENVIRONMENT)%'
          'merchantId': '%env(BRAINTREE_MERCHANT_ID)%'
          'publicKey': '%env(BRAINTREE_PUBLIC_KEY)%'
          'privateKey': '%env(BRAINTREE_PRIVATE_KEY)%'

堆栈跟踪：

    public function assertHasAccessTokenOrKeys()    {        if (empty($this->_accessToken)) {            if (empty($this->_merchantId)) {                throw new Exception\Configuration('Braintree\\Configuration::merchantId needs to be set (or accessToken needs to be passed to Braintree\\Gateway).');            } else if (empty($this->_environment)) {                throw new Exception\Configuration('Braintree\\Configuration::environment needs to be set.');            } else if (empty($this->_publicKey)) {                throw new Exception\Configuration('Braintree\\Configuration::publicKey needs to be set.');            } else if (empty($this->_privateKey)) {

ProfileController->booking_new(object(EntityManager), object(Request), object(Braintree))
in vendor\symfony\http-kernel\HttpKernel.php (line 149)

编辑3：

namespace App\Services;

use Braintree_Gateway;

class Braintree extends Braintree_Gateway
{

    //Configure Braintree Environment
    public function __construct(Braintree_Gateway $gateway)
    {
        $this->$gateway = new Braintree_Gateway([
            'environment' => 'sandbox',
            'merchantId' => 'n5z3tjxh8zd6272k',
            'publicKey' => 'v4rjdzqk3gykw4kv',
            'privateKey' => '4ab8b962e81ee8c43bf6fa837cecfb97'
        ]);
    }

    //Generate a client token
    public function generate() {
        return $clientToken = $this->clientToken()->generate();
    }

}

错误现在是：

Catchable Fatal Error: Object of class Braintree\Gateway could not be converted to string

我是否越来越接近生成客户端令牌？

Answer 1

.env文件实际上并未填充系统环境。 相反，当环境未设置时，它作为后备。 您对getenv()调用仅考虑系统环境。 要使您的文件生效，您必须使用 Service 容器。

#config/services.yaml
services:
    _defaults:
        autowire: true
        autoconfigure: true

    #... all the existing services

    Braintree_Gateway:
        class: Braintree_Gateway
        arguments:
            -
              'environment': '%env(BRAINTREE_ENVIRONMENT)%'
              'merchantId': '%env(BRAINTREE_MERCHANT_ID)%'
              'publicKey': '%env(BRAINTREE_PUBLIC_KEY)%'
              'privateKey': '%env(BRAINTREE_PRIVATE_KEY)%'

特殊参数%env()%将首先检查系统环境中的变量，如果未设置，它将通过.env文件查看是否定义了回退。 您还可以在文档中阅读此内容： https : //symfony.com/doc/current/configuration/external_parameters.html#environment-variables

这将提供您在服务中手动构建的服务Braintree_Gateway 。 就像任何其他服务一样，您可以将其注入到您的服务中，并且自动装配将传入一个已经生成的 Braintree 网关：

namespace App\Services;

use Braintree\ClientToken;

class Braintree
{
    private $gateway;

    public function __construct(\Braintree_Gateway $gateway)
    {
        $this->gateway = $gateway;
    }

    # ... methods using the gateway
}
