我正在尝试使用 PayPal-php-Sdk 创建发票，一切都很好，但是当我尝试设置账单信息时出现问题，出现此错误：
{"name":"VALIDATION_ERROR","message":"Invalid request - see details.","debug_id":"2d34973f0cfef","details":[{"field":"billing_info","issue":"Can not deserialize instance of java.util.ArrayList out of START_OBJECT token at line:1, column:2"}]}exception 'PayPal'Exception'PayPalConnectionException' with message 'Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/invoicing/invoices.' in /var/www/admin/data/www/****/vendor/paypal/rest-api-sdk-php/lib/PayPal/Core/PayPalHttpConnection.php:176

这是我使用的代码：
$client_id = "****";
$secret = "****";
$apiContext = new ApiContext(new OAuthTokenCredential(
$client_id, $secret));
$merchantInfo = new PayPal'Api'MerchantInfo();
$merchantInfo->setEmail("****");
$merchantInfo->setWebsite("****");
$billingInfo = new PayPal'Api'BillingInfo();
$billingInfo->setEmail("****");
$invoice = new PayPal'Api'Invoice();
$invoice->setMerchantInfo($merchantInfo);
$invoice->setBillingInfo($billingInfo);
try
{
$invoice->create($apiContext);
} catch (PayPal'Exception'PayPalConnectionException $ex) {
echo $ex->getData();
die($ex);
} catch (Exception $ex) {
die($ex);
}
以下是我从PayPal支持中得到的：
将这两行更改为：
$invoice->setMerchantInfo(array($merchantInfo));
$invoice->setBillingInfo(array($billingInfo));
帐单信息和商家信息都接收对象数组，而不是直接接收对象。
这很奇怪，但是当我仅为帐单信息更改此内容时，它开始起作用，因此对我来说正确的代码是：
$invoice->setMerchantInfo($merchantInfo);
$invoice->setBillingInfo(array($billingInfo));
