Question

我有一个简单的模型：

public class Item : Entity<int>
{
    [Required]
    public string Name { get; set; }
    [Required]
    public int Cost { get; set; }
}

内部控制器：

[HttpPost]
public async Task<IActionResult> Create([FromBody] Item item)
{
    if(!ModelState.IsValid) 
    {
       return BadRequest(ModelState);
    }
    repository.Create(item);
    await repository.SaveAsync();
    return Created($"/api/v1/items/{item.Id}", new { message = "Item was created successfully!" });
}

现在，为了跟踪三个不正确的样本输入，我得到以下回复：

样品＃1：

POST http://localhost:5000/api/v1/items
content-type: application/json

{
    "name": "sample1",
    "cost": $100000
}

响应：

{
  "cost": [
    "The input was not valid."
  ]
}

样本＃2：

POST http://localhost:5000/api/v1/items
content-type: application/json

{
    "name": "sample2",
    "cost": "10000000000000000000000000"
}

响应：

{
  "cost": [
    "The input was not valid."
  ]
}

示例＃3：这个似乎是一个错误。出现一个空键（而不是int超出范围错误）

POST http://localhost:5000/api/v1/items
content-type: application/json

{
    "name": "sample3",
    "cost": 10000000000000000000000000
}

响应：

{
  "": [
    "The input was not valid."
  ],
  "cost": [
    "The input was not valid."
  ]
}

第一个和最后一个是无效的json，第二个是整数cost的数字太高。确保您的费用不超过INT_MAX: 2147483647。
