Returned Values¶
Status Code¶
After you send 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 response. For more information, see Status Codes.
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.
Figure 1 shows the response header for the API used to obtain a user token, in which x-subject-token is the required user token. Then, this token can be used to authenticate the calling of other APIs.

(Optional) Response Body¶
This part is optional. A response body is generally returned in a structured format (for example, JSON or XML), corresponding to Content-Type in the response header, and is used to transfer content other than the response header.
If the following information is returned for calling the API used to obtain a user token, the request is successful. The following describes part of the request body.
{
"token": {
"expires_at": "2019-02-13T06:52:13.855000Z",
"methods": [
"password"
],
"catalog": [
{
"endpoints": [
{
"region_id": "aaa",
......
If an error occurs during API calling, an error code and error message will be displayed. The following is an error response body:
{
"error_msg": "Parameter error",
"error_code": "DBS.200001"
}
In the response, error_code indicates an error code, and error_msg describes the error.
