我有一个 ASP.NET Core API 调用第二个 API。
如果第二个 API 出现错误,我会在服务层抛出异常:
var response = await httpClient.SendAsync(request); //call second API
if (!response.IsSuccessStatusCode)
{
//return HTTP response with StatusCode = X, if response.StatusCode == X
throw new HttpRequestException(await response.Content.ReadAsStringAsync());
//this always returns 400
}
如何抛出一个异常,该异常将从第二个 API 调用中返回具有相同状态代码的响应?
如果我使用HttpRequestException
它总是返回 400,即使response
对象有StatusCode = 500
.
EDIT:第一个 API 端点如下所示:
public async Task<ActionResult<HttpResponseMessage>> CreateTenancy([FromBody]TenancyRequest tenancy)
{
//Make some calls...
return Created(string.Empty, new { TenancyID = newTenancyExternalId });
}
第二个 API 端点如下所示:
[HttpPost]
public IHttpActionResult CreateTenancy([FromBody]TenancyDTO tenancyDTO)
{
var tenancy = GetTenancy();
return Created(string.Empty, tenancy);
}
我尝试过使用throw new HttpResponseException(response);
但这会删除描述性异常消息,有效负载最终如下所示:
{
"Code": 500,
"CorrelationId": "2df08016-e5e3-434a-9136-6824495ed907",
"DateUtc": "2020-01-30T02:02:48.4428978Z",
"ErrorMessage": "Processing of the HTTP request resulted in an exception. Please see the HTTP response returned by the 'Response' property of this exception for details.",
"ErrorType": "InternalServerError"
}
我想保留ErrorMessage
原始有效负载中的值:
{
"Code": 400,
"CorrelationId": "ff9466b4-8c80-4dab-b5d7-9bba1355a567",
"DateUtc": "2020-01-30T03:05:13.2397543Z",
"ErrorMessage": "\"Specified cast is not valid.\"",
"ErrorType": "BadRequest"
}
最终目标是返回此值:
{
"Code": 500,
"CorrelationId": "ff9466b4-8c80-4dab-b5d7-9bba1355a567",
"DateUtc": "2020-01-30T03:05:13.2397543Z",
"ErrorMessage": "\"Specified cast is not valid.\"",
"ErrorType": "InternalServerError"
}
