【问题描述】:
我正在向 REST 服务发出 HTTP 发布请求,当我返回 HttpWebResponse 时,我正在执行以下检查。当我在做 webresponse 时,我是否也应该检查 responseStream != null != null
HttpWebResponse webResponse = webRequest.GetResponse() as HttpWebResponse;
if (webResponse != null)
{
var responseStream = webResponse.GetResponseStream();
int responseCode = (int)webResponse.StatusCode;
if (responseStream != null && responseCode == (int)HttpStatusCode.Created)
{
cmsStoreWebResponse = ((new StreamReader(responseStream)).ReadToEnd());`
}
else
{
this.LogError(string.Format("{0}\n Endpoint: {1}\n {2} {3} {4}", ErrorCodes.IWS_CMSRetrieve_ERROR_001, oagEndpointUrl, ErrorCodes.IWS_CMSStore_ERROR_SERVICE_DOWN, responseStream, responseCode));
serviceData.Fatal = true;
serviceData.ErrorCode = ErrorCodes.IWS_EFORMSFORMSETS_001;
serviceData.ErrorDetails = string.Format("\nEndpoint: {0}\n {1}", oagEndpointUrl, ErrorCodes.RESPONSE_STREAM_NULL);
throw new FaultException<ServiceExceptionData>(serviceData, new FaultReason(string.Format("\nEndpoint: {0}\n {1}", oagEndpointUrl, ErrorCodes.RESPONSE_STREAM_NULL)));
}
}
else
{
this.LogError(string.Format("{0}\n Endpoint: {1}\n {2}", ErrorCodes.IWS_CMSRetrieve_ERROR_001, oagEndpointUrl, ErrorCodes.IWS_CMSStore_ERROR_SERVICE_DOWN));
serviceData.Fatal = true;
serviceData.ErrorCode = ErrorCodes.IWS_EFORMSFORMSETS_001;
serviceData.ErrorDetails = string.Format("\nEndpoint: {0}\n {1}", oagEndpointUrl, ErrorCodes.RESPONSE_STREAM_NULL);
throw new FaultException<ServiceExceptionData>(serviceData, new FaultReason(string.Format("\nEndpoint: {0}\n {1}", oagEndpointUrl, ErrorCodes.RESPONSE_STREAM_NULL)));
}
