目前我正在構建我的第一個 Web API。要求是以 JSON 格式顯示發生的任何錯誤作為響應這是我的 ResponseData 類public class ResponseData { public List<AccountDTO> AccountList { set; get; } public string ReturnMessage { set; get; } public string error { get; set; } public string code { get; set; } public string message { get; set; } public string innererror { get; set; } public string type { get; set; } public string stacktrace { get; set; }}這是我的控制器例如，如果我的代碼執行該catch塊，我將收集異常的所有信息并以格式化的JSON.[HttpGet] public ResponseData getAllAccounts(string BRN, string CompanyName) { ResponseData response = new ResponseData(); List<AccountDTO> accountlist = null; IAccountInterface usecase = new AccountDAO(); try { if (BRN != null && CompanyName != null) { accountlist = usecase.getAccountbyBRNCompanyName().Where(p => p.BRN.ToLower().Equals(BRN.ToLower()) && p.CompanyName.ToLower().Contains(CompanyName.ToLower())).ToList(); response.ReturnMessage = "Data filter by BRN and CompanyName."; } else { response.ReturnMessage = "Data filter cannot be null."; } response.AccountList = accountlist; } catch (Exception e) { //response.ReturnMessage = JsonConvert.SerializeObject(errorFormat); } return response; }運行此 Web APi 后，如果執行了 catch 塊，則響應如下圖所示。到目前為止，它幾乎與我想要的相似。但是，無論錯誤與否，我的 WEB API 響應都會采用這種格式。我知道這是因為我返回 aresponse object所以我的所有對象屬性都會顯示出來。這是我想要實現的示例響應。有關錯誤的詳細信息以 JSON 形式包含在響應中。錯誤將采用這種格式。任何幫助和指導都非常感謝。{ "error":{ "code": "<This code is not related to..>", "message": "<A message describing the error..>", "innererror": { "message": "<A message describing the error..>", "type": "Microsoft.Crm.CrmHttpException", "stacktrace": "<Details from the server about where the error occurred>" } } }

所需的 JSON 錯誤響應模型與使用的類不匹配。
當前的對象模型承擔多種職責。
考慮重構類模型以服務于單一職責
public class ResponseData {
public List<AccountDTO> AccountList { set; get; }
public string ReturnMessage { set; get; }
}
還可以重構 API 操作以根據操作流返回適當的響應。
[HttpGet]
public IHttpActionResult getAllAccounts(string BRN, string CompanyName) {
try {
ResponseData response = new ResponseData();
List<AccountDTO> accountlist = null;
IAccountInterface usecase = new AccountDAO();
if (BRN != null && CompanyName != null) {
accountlist = usecase.getAccountbyBRNCompanyName().Where(p => p.BRN.ToLower().Equals(BRN.ToLower()) && p.CompanyName.ToLower().Contains(CompanyName.ToLower())).ToList();
response.ReturnMessage = "Data filter by BRN and CompanyName.";
} else {
response.ReturnMessage = "Data filter cannot be null.";
}
response.AccountList = accountlist;
return Ok(response);
}
catch (Exception e) {
Console.WriteLine("Error: " + e.Message + ", Stack: " + e.StackTrace);
var response = new {
error = new {
code = "sample code",
message = e.Message,
innererror = new {
message = e.Message,
type = e.GetType().Name,
stacktrace = e.StackTrace
}
}
}
var responseMessage = Request.CreateResponse(HttpStatusCode.InternalServerError, response);
return ResponseMessage(responseMessage);
}
}

Console.WriteLine("Error: " + e.Message + ", Stack: " + e.StackTrace);
response.error.code = "sample code";
response.error.message = e.Message;
response.error.innererror = "{";
response.error.message = e.Message;
response.error.type = "ExceptionType + ...";
response.error.stacktrace = e.StackTrace;
這應該會給你你想要的結果。響應對象也必須重構。
