Question

当我向后续行动提出要求时

[HttpPost]
public ResponseOutput Incremental(List<Product> inputList)
{
    return true;
}

参数inputList始终为null。我的目标：

public class Product
{
    public string ContractNo { get; set; }
    public string Sku { get; set; }
    public double Alis { get; set; }
    public string Kur { get; set; }
    public string SupplierNumber { get; set; }
    public ActionType Islem { get; set; }
}

ActionType是枚举。

我的请求机构：

POST /api/Konsinye/ConsigneeInsertIncremental HTTP/1.1
Host: localhost:38664
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 9e5f759c-552d-2e3e-f704-28ec91045e6c

{
 "inputList" : [
    {
      "ContractNo" : "123",
      "Sku" : "1234",
      "Alis" : "112",
      "Kur" : "TRY",
      "SupplierNumber" : "000",
      "Islem" : "1"
    }
  ]
}

问题是，参数始终为null。我尝试将[FromBody]添加到签名中，但它没有帮助。

尝试这种方法（将对象数组传输到服务器而不是具有数组属性的单个对象）：

[HttpPost]
public IHttpActionResult Incremental(List<ConsigneeProductInput> data)
{
    return Ok();
}

来自邮递员的身体：

[
    {
      "ContractNo" : "123",
      "Sku" : "1234",
      "Alis" : "112",
      "Kur" : "TRY",
      "SupplierNumber" : "000",
      "Islem" : "1"
    }
]

复杂的post参数始终为null
