Braintree dropin UI -访问令牌需要传递给Braintree\Gateway

Question

带有Braintree JS插入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();
}

我得到了以下错误：

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

BT配置已经正确地输入到.env文件中。为什么它不设置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)) {

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

我离生成客户端令牌越来越近了吗？

.env-file实际上并不填充系统环境。相反，当没有设置环境时，它会作为后盾。对getenv()的调用只考虑了系统环境。要使文件生效，必须使用服务容器。

#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()%将首先检查您的系统环境中的变量，如果没有设置，它将遍历.env文件，以查看是否定义了回退。您还可以在docs：parameters.html#environment-variables中阅读这方面的内容。

这将给出您在服务中手动构建的服务Braintree_Gateway。与任何其他服务一样，您可以将其插入到服务中，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
}
