For example, when calling CAM API (version: 2017-03-12) to view the status of instances (DescribeInstancesStatus), if the request has succeeded, you may see the response as shown below:
{
"Response": {
"TotalCount": 0,
"InstanceStatusSet": [],
"RequestId": "b5b41468-520d-4192-b42f-595cc34b6c1c"
}
}
Response
, which contains RequestId
, as long as it processes the request. It does not matter if the request is successful or not. TotalCount
and InstanceStatusSet
are the fields specified by the API DescribeInstancesStatus
. 0 TotalCount
means that the requester owns 0 CVM instance so the InstanceStatusSet
is empty.If the request has failed, you may see the response as shown below:
{
"Response": {
"Error": {
"Code": "AuthFailure.SignatureFailure",
"Message": "The provided credentials could not be validated. Please ensure your signature is correct."
},
"RequestId": "ed93f3cb-f35e-473f-b9f3-0d451b8b79c6"
}
}
Error
field indicates that the request has failed. A response for a failed request will include Error
, Code
and Message
fields.Code
is the code of the error that helps you identify the cause and solution. There are two types of error codes so you may find the code in either common error codes or API-specified error codes.If there is an Error field in the response, it means that the API call failed. The Code field in Error indicates the error code. The following table lists the common error codes that all actions can return.
