如何使用 Express Validator 通配符验证对象和子对象数组答案

【问题标题】：How to Validate an Array of Objects and Sub-Objects using Express Validator Wildcards如何使用 Express Validator 通配符验证对象和子对象数组
【发布时间】：2020-11-13 10:37:46
【问题描述】：

我正在尝试验证通过 JSON 请求中的对象数组传递的数据。我使用了文档中指定的 express-validator 通配符，但无论对象的属性是否为空，都会返回错误消息。我已经在网上检查了各种解决方案，试图调试这个问题，但都无济于事。如果有人能指出我做错了什么并提出正确的解决方案，我将不胜感激，谢谢。

验证

body("*.product", "Invalid or Empty Product Details").trim().notEmpty(),
body("*.price", "Invalid or Empty Product Price").trim().notEmpty(),
body("*.customer", "Invalid or Empty Customer Details")
   .trim()
   .notEmpty(),
body("*.seller", "Invalid or Empty Seller Details").trim().notEmpty(),
body("*.haulageOptions", "Invalid or Empty Haulage Options").trim().notEmpty()

JSON 请求

{
    "order": [
        {
            "product": {
                "commodity": "",
                "quantity": ""
            },
            "price": {
                "orderPrice": "",
                "deliveryPrice": "",
                "totalPrice": ""
            },
            "customer": {
                "name": "",
                "email": "",
                "location": {
                    "state": "",
                    "localGovernment": "",
                    "town": "",
                    "address": ""
                }
            },
            "seller": {
                "name": "",
                "phone": [
                    ""
                ],
                "email": ""
            },
            "haulageOptions": {
                "firstOrder": "",
                "secondOrder": "",
                "thirdOrder": ""
            }
        }
    ]
}
