【解决方案1】：

我用这个更新了在我的配置文件夹中找到的 paypal.php 文件

<?php
/**
 * PayPal Setting & API Credentials
 * Created by Raza Mehdi <srmk@outlook.com>.
 */

return [
    'mode'    => env('PAYPAL_MODE', 'sandbox'), // Can only be 'sandbox' Or 'live'. If empty or invalid, 'live' will be used.
    'sandbox' => [
        'username'    => env('PAYPAL_SANDBOX_API_USERNAME', ''),
        'password'    => env('PAYPAL_SANDBOX_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_SANDBOX_API_SECRET', ''),
        'certificate' => env('PAYPAL_SANDBOX_API_CERTIFICATE', ''),
        'app_id'      => 'APP-80W284485P519543T', // Used for testing Adaptive Payments API in sandbox mode
    ],
    'live' => [
        'username'    => env('PAYPAL_LIVE_API_USERNAME', ''),
        'password'    => env('PAYPAL_LIVE_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_LIVE_API_SECRET', ''),
        'certificate' => env('PAYPAL_LIVE_API_CERTIFICATE', ''),
        'app_id'      => '', // Used for Adaptive Payments API
    ],

    'payment_action' => 'Sale', // Can only be 'Sale', 'Authorization' or 'Order'
    'currency'       => env('PAYPAL_CURRENCY', 'USD'),
    'billing_type'   => 'MerchantInitiatedBilling',
    'notify_url'     => '', // Change this accordingly for your application.
    'locale'         => '', // force gateway language  i.e. it_IT, es_ES, en_US ... (for express checkout only)
    'validate_ssl'   => true, // Validate SSL when creating api client.
];

【解决方案2】：

基本上，你需要匹配.env变量和config/paypa.php变量。

PAYPAL_MODE=sandbox
PAYPAL_CURRENCY=USD
PAYPAL_SANDBOX_API_USERNAME=username
PAYPAL_SANDBOX_API_PASSWORD=password
PAYPAL_SANDBOX_API_SECRET=secret-key-or-signature

您可以通过导航至paypal sandbox dashboard > leftnav > accounts > sandbox > list of account > view/edit account (action drop down) > API Credentials tab 来检索这些信息。

你的 config/paypal.php 应该传递相同的变量。

return [
    'mode'    => env('PAYPAL_MODE', 'sandbox'), // Can only be 'sandbox' Or 'live'. If empty or invalid, 'live' will be used.
    'sandbox' => [
        'username'    => env('PAYPAL_SANDBOX_API_USERNAME', ''),
        'password'    => env('PAYPAL_SANDBOX_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_SANDBOX_API_SECRET', ''),
        'certificate' => env('PAYPAL_SANDBOX_API_CERTIFICATE', ''),
        'app_id'      => 'APP-80W284485P519543T',
        // 'client_id'         => env('PAYPAL_SANDBOX_CLIENT_ID', ''),
        // 'client_secret'     => env('PAYPAL_SANDBOX_CLIENT_SECRET', ''),
        // 'app_id'            => 'APP-80W284485P519543T',
    ],
    'live' => [
        // 'client_id'         => env('PAYPAL_LIVE_CLIENT_ID', ''),
        // 'client_secret'     => env('PAYPAL_LIVE_CLIENT_SECRET', ''),
        // 'app_id'            => '',
        'username'    => env('PAYPAL_SANDBOX_API_USERNAME', ''),
        'password'    => env('PAYPAL_SANDBOX_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_SANDBOX_API_SECRET', ''),
        'certificate' => env('PAYPAL_SANDBOX_API_CERTIFICATE', ''),
        'app_id'      => '',
    ],

    'payment_action' => env('PAYPAL_PAYMENT_ACTION', 'Sale'), // Can only be 'Sale', 'Authorization' or 'Order'
    'currency'       => env('PAYPAL_CURRENCY', 'USD'),
    'notify_url'     => env('PAYPAL_NOTIFY_URL', ''), // Change this accordingly for your application.
    'locale'         => env('PAYPAL_LOCALE', 'en_US'), // force gateway language  i.e. it_IT, es_ES, en_US ... (for express checkout only)
    'validate_ssl'   => env('PAYPAL_VALIDATE_SSL', true), // Validate SSL when creating api client.
];

注意沙盒和实时数组，我已经用新的注释了默认数组项。
