Response

Status Code

A status code is a group of digits, ranging from 1xx to 5xx. It indicates the status of a request. For more information, see Status Codes.

For example, if status code 201 is returned for calling the API for obtaining a user token, the request is successful.

Response Header

Similar to a request, a response also has a header, for example, Content-Type.

In the response to the API for obtaining a user token, x-subject-token is the desired user token. This token can then be used to authenticate the calling of other APIs.

Response Body

A response body is generally returned in structured format. It corresponds to Content-Type in the response header and transfers content except the response header.

The following is part of the response body of the API for obtaining a user token.

{ 
    "token": { 
        "expires_at": "2019-02-13T06:52:13.855000Z", 
        "methods": [ 
            "password" 
        ], 
        "catalog": [ 
            { 
                "endpoints": [ 
                    { 
                        "region_id": "xx-xxxxxx-1", 
......

If an error occurs during API calling, an error code and a message will be displayed. The following shows an error response body.

{
  "error_code": "FGS.0111",
  "error_msg": "xxxxxxxxx"
} 

In the response body, error_code is an error code, and error_msg provides information about the error.
