How to deal with the returned results after the interface call? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Return the result

The returned results are mainly in XML and JSON formats. The default is XML. You can specify the common request parameter Format to change the format of the returned results. For ease of viewing and beauty, the return examples of API documents are treated with line wrapping and indentation, and there is no line wrapping and indentation processing for the actual returned results.

Normal return example

When the API is called successfully, the API return parameters and request ID will be returned. We call this a normal return. The HTTP status code is 2xx.

XML example

4C467B38-3910-447D-87BC-AC049166F216

JSON example

{"RequestId": "4C467B38-3910-447D-87BC-AC049166F216" / * return result data * /}

Exception return example

After an error occurs in the API call, an error code, an error message and a request ID will be returned. This is called an exception return. The HTTP status code is 4xx or 5xx.

You can troubleshoot errors based on the interface error code, the common error code and the API error center. When you are unable to troubleshoot the error, you can submit a ticket to contact us and indicate the service node HostId and RequestId in the ticket.

XML example

540CFF28-407A-40B5-B6A5-74Bxxxxxxxxx ecs.aliyuncs.com MissingParameter.CommandId The input parameter "CommandId" that is mandatory for processing this request is not supplied.

JSON example

{"RequestId": "540CFF28-407A-40B5-B6A5-74Bxxxxxxxxx", / * request ID * / "HostId": "ecs.aliyuncs.com", / * service node * / "Code": "MissingParameter.CommandId", / * error code * / "Message": "The input parameter" CommandId "that is mandatory for processing this request is not supplied." / * error message * /}
