我上面的代码没有按预期创建订单，我正在通过 USSD 系统使用 REST API 向 WordPress 网站发出订单请求。
因此，我使用 Postman 来测试与网站的 API 连接，方法是使用默认 API 端点购买实时产品来创建订单，并且它有效
我的挑战是如何让 PHP 文件能够做到这一点因为 PHP 代码中已经提供了所需的每个参数，但 WordPress 网站上没有显示任何订单
{
"payment_method": "bacs",
"payment_method_title": "Afro Lotto Checkout",
"set_paid": true,

],
"shipping_lines": [

}
这是 $response 变量的值：
Order creation response: {
"code":"rest_invalid_param",
"message":"Invalid parameter(s): billing, shipping, shipping_lines",
"data":{
"status":400,
"params":{
"billing":"billing[first_name] is not of type string.",
"shipping":"shipping[first_name] is not of type string.",
"shipping_lines":"shipping_lines[0][total] is not of type string."
},
"details":{
"billing":{
"code":"rest_invalid_type",
"message":"billing[first_name] is not of type string.",
"data":{
"param":"billing[first_name]"
}
},
"shipping":{
"code":"rest_invalid_type",
"message":"shipping[first_name] is not of type string.",
"data":{
"param":"shipping[first_name]"
}
},
"shipping_lines":{
"code":"rest_invalid_type",
"message":"shipping_lines[0][total] is not of type string.",
"data":{
"param":"shipping_lines[0][total]"
}
}
}
}
}
所以我根据错误日志的响应对代码做了一些更改。我定义了计费和运输的默认值：
// Define default billing and shipping values
$default_billing_values = array(
'first_name' => (string)$msisdn,
'last_name' => 'USSD',
'address_1' => 'USSD',
'address_2' => '',
'city' => 'USSD',
'state' => 'AH',
'postcode' => '',
'country' => 'GH',
'email' => '[email protected]',
'phone' => (string)$msisdn
);
$default_shipping_values = array(
'first_name' => (string)$msisdn,
'last_name' => 'USSD',
'address_1' => 'USSD',
'address_2' => '',
'city' => 'USSD',
'state' => 'AH',
'postcode' => '',
'country' => 'GH'
);
然后我使用客户的信息（如果存在），否则我使用默认值：
// Check if customer exists, use customer data if available, otherwise use default values
if ($customerExists) {
$customer_id = isset($customer_data['id']) ? $customer_data['id'] : null;
$billing_data = isset($customer_data['billing']) ? $customer_data['billing'] : $default_billing_values;
$shipping_data = isset($customer_data['shipping']) ? $customer_data['shipping'] : $default_shipping_values;
} else {
$billing_data = $default_billing_values;
$shipping_data = $default_shipping_values;
}
然后我构建订单数据：
// Construct order data
$order_data = array(
'payment_method' => 'paystack',
'payment_method_title' => 'paystack',
'customer_id' => intval($customer_id),
'set_paid' => true,
'billing' => $billing_data,
'shipping' => $shipping_data,
'line_items' => array(
array(
'product_id' => intval($product_id),
'quantity' => intval($quantity)
)
),
'shipping_lines' => array(
array(
'method_id' => 'free_shipping',
'method_title' => 'Free Shipping',
'total' => '0.00'
)
)
);
其余代码基本保持不变:)
祝你好运，编码愉快！
