WooCommerce配置越南支付通道完整指南
前期准备
-
注册越南支付服务商账户
- 选择适合的越南本地支付提供商（如Momo、ZaloPay、VNPAY等）
- 完成商户注册和验证流程
-
获取API凭证
- API Key/Secret
- Merchant ID
- Payment Gateway URL
-
确保WooCommerce环境
- WordPress最新版本
- WooCommerce插件已安装并更新至最新版
配置步骤
方法一：使用官方/第三方支付网关插件
-
安装支付网关插件：
在WordPress后台 > 插件 > 新增，搜索并安装相应越南支付的官方或兼容插件（如"WooCommerce VNPAY"） -
激活并配置插件：
进入WooCommerce > 设置 > Payments，启用您选择的越南支付方式，填写以下信息： -
基本设置：
- Title: [显示给客户的名称，如"VNPAY"]
- Description: [可选描述]
- Enabled: ✔️是
- API配置：
- Merchant ID: [您的商户ID]
- Hash Secret: [从支付提供商获取]
- Payment Gateway URL: [提供商的API端点]
- 高级设置：
- Order Status After Payment: Processing/Completed (根据业务需求选择)
方法二：自定义支付网关开发（若无官方插件）
1. 创建自定义支付网关
在主题的functions.php或通过子主题/插件添加以下代码框架：
/
* 越南自定义支付网关类
*/
class WC_Vietnam_Custom_Gateway extends WC_Payment_Gateway {
public function __construct() {
$this->id = 'vietnam_custom_gateway';
$this->method_title = __('越南支付', 'woocommerce');
$this->method_description = __('通过越南本地支付方式处理订单', 'woocommerce');
// 初始化表单字段
$this->init_form_fields();
// 加载设置
$this->init_settings();
// 定义用户可见字段
$this->title = $this->get_option('title');
// API配置保存钩子
add_action('woocommerce_update_options_payment_gateways_' . $this->id, array($this, 'process_admin_options'));
}
/
* 后台配置字段
*/
public function init_form_fields() {
/* ...详细字段定义见下一步... */
}
/
* 处理付款
*/
public function process_payment($order_id) {
/* ...付款逻辑实现见后续步骤... */
}
}
// 注册网关到WooCommerce
function add_vietnam_custom_gateway($methods) {
if (class_exists('WC_Vietnam_Custom_Gateway')) {
$methods[] = 'WC_Vietnam_Custom_Gateway';
}
return $methods;
}
add_filter('woocommerce_payment_gateways', 'add_vietnam_custom_gateway');
2. init_form_fields()详细实现
public function init_form_fields() {
$this->form_fields = array(
'enabled' => array(
'title' => __('启用/禁用', 'woocommerce'),
'type' => 'checkbox',
'label' => __('启用越南支付通道', 'woocommerce'),
'default' => 'yes'
),
'title' => array(
'title'=>__('显示名称','woocommerce'),
'type'=>'text',
'sanitize_callback'=>'sanitize_text_field',
'maxlength'=>50,
),

'marchant_id'=>array(
'title'=>__('商户ID','your-text-domain'),
),
'app_key'=>array(
'title'=>__('应用密钥','your-text-domain'),
),
// ▼▼▼ URL回调配置 ▼▼▼
'success_url'=>array(
'title'=>'成功回调URL（自动生成）',
),
'refund_url'=>array(
),
// ▼测试模式开关

3. 支付处理逻辑实现 (process_payment方法)
public function process_payment($order_id) {
$order = wc_get_order($order_id);
// 1. 构建越南支付网关请求参数
$payment_args = array(
'merchant_id' => $this->get_option('merchant_id'),
'order_id' => $order->get_order_number(),
'amount' => (int)($order->get_total() * 100), // 转换为分单位
'currency' => get_woocommerce_currency(),
'return_url' => $this->get_return_url($order),
'notify_url' => add_query_arg('wc-api', strtolower(get_class($this)), home_url('/')),
// ▼▼▼越南本地化必填字段（根据具体API调整）▼▼▼
'customer_name' => sanitize_text_field($_POST['billing_first_name'] . $_POST['billing_last_name']),
'customer_email' => sanitize_email($_POST['billing_email']),
'_vietnam_specific_param1_' : '', // MoMo/ZaloPay等特有参数
// ▼签名生成（关键安全步骤）
'_signature_' : hash_hmac(
"SHA256",
implode("|", [$args['merchant_id'],$args['amount'],$args["txn_ref"]]),
trim(esc_html( wp_unslash( $_REQUEST[ "_wpnonce" ] ?? "" ) )
)
);
/* ---------------------------
2. API请求示例 (以VNPAY为例)
--------------------------- */
try{
$response = wp_remote_post(
($this->settings["sandbox_mode"]=="yes") ?
"https://sandbox.vnpayment.vn/paymentv2/vpcpay.html" :
"https://vnpayment.vn/paymentv2/vpcpay.html",
array(
"headers" : ["Content-Type"=>"application/json"],
"body" : json_encode($payment_args),
"timeout" : 45,
/
* SSL验证配置（越南部分CA需特殊处理）
* @link https://curl.se/docs/caextract.html
*/
"sslverify": file_exists("/path/to/cacert.pem"),
)
);
if(is_wp_error($response)){
throw new Exception(__("支付网关连接失败: ", "") . esc_html_e(response));
}
/* --------------------------------------
3.处理响应结果（成功跳转/错误提示）
-------------------------------------- */
if(wp_remote_retrieve_response_code(response)==200){
return array(
/ VNPAY/MoMo返回的是HTML表单自动提交 */
result ⇒ success,
redirect ⇒ esc_url_raw(json_decode(wp_remote_body())→redirect_url)
);
} else {
wc_add_notice(__("支付初始化失败: ","") . response["message"], error);
return null;
}
} catch(Exception ex){...}
}
4. IPN回调处理
在类中添加以下方法处理异步通知：
/
* Webhook/IPN回调验证 (关键安全步骤)
*/
public function verify_ipn_response(){
check_admin_referer();
/* ▼获取原始输入流（避免PHP全局变量被篡改）*/
raw_post_data = file_get_contents('php://input');
/* ▼验证签名（以VNPAY为例）*/
received_signature = $_SERVER["HTTP_VNP_SIGNATURE"];
expected_signature = hash_hmac("sha512", raw_post_data, this→app_secret);
if(!hash_equal(received_signature, expected_signature)){
status_header(403); exit;
}
/* ----------------------------------------------------
订单状态更新逻辑 （注意防重复通知和金额校验！）
---------------------------------------------------- */
order_ID_match_array();
preg_match("/\d+/",esc_html(raw_request[“vnp_TxnRef”]), order_ID_match_array);
order=wc_get_order(absint(order_ID_match_array[0]));
if(!empty(order) && !in_array(order.get_status(),array(“processing”,“completed”)){
/ ▼金额一致性检查（必须防御中间人攻击！）*/
paid_amount=intval(raw_request[“vnp_amount”])/100;
if(abs(floatval(order.total)-paid_amount)>0.01){
log_error("[Vietnam-Gateway] Amount mismatch for Order #".absint(ID));
/ ▲实际业务中可能需要人工审核异常订单▲ */
} elseif(strtoupper(raw_request[“code”])=="00")){
order.update_status(this→success_status,"__('越南支付成功','')");
WC()->cart.empty_cart();//清空购物车
echo json_encode(array(“RspCode”:”00”, “Message”:”Confirm Success”)；
}}} add_action('woocommerce_api_wc_vietnam_custom_gateway',array(this,'verify_ipn_response'));
5. WooCommerce前台适配
(A) JavaScript动态加载本地支付LOGO
在主题的footer.php或通过插件添加：
jQuery(document).ready(function(){
jQuery('#payment_method_vietnam_custom_gateway').prev().append('<img src="<?=plugins_url("assets/vietnam-pay-logo.png"?>" style="height:25px;vertical-align:text-top">');
/* MoMo/VNPAY要求动态显示QR码的情况：*/
if(jQuery("#place_order").length>0){
fetchDynamicQrCodeFromBackend();//需自行实现API端点
}});
(B) CSS样式优化
/* payment-method-vietnam.css */
li.wc_payment_method.payment_method_vietnam_custom_gateway label img{
max-height:30px!important;
margin-left:10px;
border-radius:4px;
}
/* RTL语言支持 （如需要阿拉伯语/越南语混合排版）*/
html[dir="rtl"] .method-description-vnm{
direction:rtl;
unicode-bidi:bidi-override;
}
6.测试与上线
| 阶段 | 操作要点 |
|---|---|
| 沙盒测试 | – VPN切换至越南IP测试地理封锁 – Currency强制为VND – WooCommerce启用调试日志 |
| 生产检查清单 | – SSL证书全站强制HTTPS – CronJob监控未完成订单 – AppSecret使用KMS加密存储 |
常见问题排查：
Signature mismatch: 时区设置为Asia/HoChiMinh (+7 GMT)Amount invalid: WooCommerce货币设置里确保小数位数为0(VND无小数)
