如何显示确切的错误而不是 ASP.NET Web API 返回 UnknowError(500)

Question

当找不到带有公司 ID 的公司时，我想返回 404 状态码。但是 Web API 总是返回；

  "error": {
    "message": "An error has occurred. Please, try it later.",
    "issuedAt": "2020-08-18T08:06:19.4650733Z",
    "code": "UnknownError",
    "statusCode": 500
  }
}

这是我的 CustomerProvider 代码；

public class CustomerProvider: ICustomerProvider
    {
        public CustomerProvider GetCustomerDetails()
        {
            //.....
            //.....
            
                if (customerDetails == null)
                {
                    var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
                    {
                        Content = new StringContent(string.Format("No customer with ID = {0}", customerId)),
                        ReasonPhrase = "Company ID Not Found"
                    };
                    throw new HttpResponseException(resp);
                }
            
                return customerDetails;
        }
    }

如何返回 404 状态码？

Answer 1

试试

HttpResponseMessage err_response = (HttpResponseMessage)Request.CreateErrorResponse(HttpStatusCode.NotFound, "Your Message");
return err_response;

我不建议因为它不是（404）它是“服务器错误（500）”
