Response

Status Code

After sending a request, you will receive a response, including a status code, response header, and response body.

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 used to obtain a user token, the request is successful.

Response Header

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

Table 1 Response header

Parameter

Description

Content-Length

Indicates the length of the response body. The unit is byte.

Date

Indicates the time when a request response is returned.

Content-Type

Indicates the MIME type of the response body.

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

Response Body

The body of a response is often returned in structured format as specified in the Content-Type header field. The response body transfers content except the response header.

The following is part of the response body for the API used to obtain a user token.

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

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

{ 
    "error_msg": "The format of message is error", 
    "error_code": "AS.0001" 
}

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