**题目描述补充**：
在电商系统中，经常需要处理订单的相关操作，如订单创建、查询、更新和删除等。本题目聚焦于订单查询中的一个具体场景：**根据用户ID和订单状态查询订单列表**。系统需要能够接收用户ID和订单状态作为查询条件，返回符合这些条件的订单列表。订单状态可以是待支付、已支付、已发货、已取消等。
**示例输入**：
- 用户ID: 1001
- 订单状态: "已支付"
**示例输出**：
```json
[
{
"orderId": "OD123456",
"userId": 1001,
"status": "已支付",
"totalAmount": 199.99,
"orderDate": "2023-04-01T12:00:00Z"
},
{
"orderId": "OD789012",
"userId": 1001,
"status": "已支付",
"totalAmount": 249.99,
"orderDate": "2023-04-02T15:30:00Z"
}
]
```
**PHP 示例代码**：
```php
"OD123456", "userId" => 1001, "status" => "已支付", "totalAmount" => 199.99, "orderDate" => "2023-04-01T12:00:00Z"],
["orderId" => "OD789012", "userId" => 1001, "status" => "已支付", "totalAmount" => 249.99, "orderDate" => "2023-04-02T15:30:00Z"],
["orderId" => "OD345678", "userId" => 1002, "status" => "待支付", "totalAmount" => 149.99, "orderDate" => "2023-04-03T08:00:00Z"],
];
$filteredOrders = array_filter($orders, function($order) use ($userId, $status) {
return $order['userId'] == $userId && $order['status'] == $status;
});
return $filteredOrders;
}
// 示例使用
$userId = 1001;
$status = "已支付";
$orders = getOrdersByUserAndStatus($userId, $status);
echo json_encode($orders, JSON_PRETTY_PRINT);
?>
```
**Python 示例代码**：
```python
def get_orders_by_user_and_status(user_id, status):
orders = [
{"orderId": "OD123456", "userId": 1001, "status": "已支付", "totalAmount": 199.99, "orderDate": "2023-04-01T12:00:00Z"},
{"orderId": "OD789012", "userId": 1001, "status": "已支付", "totalAmount": 249.99, "orderDate": "2023-04-02T15:30:00Z"},
{"orderId": "OD345678", "userId": 1002, "status": "待支付", "totalAmount": 149.99, "orderDate": "2023-04-03T08:00:00Z"},
]
filtered_orders = [order for order in orders if order['userId'] == user_id and order['status'] == status]
return filtered_orders
# 示例使用
user_id = 1001
status = "已支付"
orders = get_orders_by_user_and_status(user_id, status)
print(json.dumps(orders, indent=4))
```
**JavaScript 示例代码**：
```javascript
function getOrdersByUserAndStatus(userId, status) {
const orders = [
{ orderId: "OD123456", userId: 1001, status: "已支付", totalAmount: 199.99, orderDate: "2023-04-01T12:00:00Z" },
{ orderId: "OD789012", userId: 1001, status: "已支付", totalAmount: 249.99, orderDate: "2023-04-02T15:30:00Z" },
{ orderId: "OD345678", userId: 1002, status: "待支付", totalAmount: 149.99, orderDate: "2023-04-03T08:00:00Z" },
];
const filteredOrders = orders.filter(order => order.userId === userId && order.status === status);
return filteredOrders;
}
// 示例使用
const userId = 1001;
const status = "已支付";
const orders = getOrdersByUserAndStatus(userId, status);
console.log(JSON.stringify(orders, null, 4));
```
