Returned Values
Status Code
After sending a request, you will receive a response, including the 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 Code.
If status code 201 is returned for calling the API used to obtain a user token, the request is successful.
Response Header
A response header corresponds to a request 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 desired user token. Then, you can use the token 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 response body is returned for calling the API used to obtain a user token, the request is successful. The following shows part of the response body for the API to obtain a user token.
{
"token": {
"expires_at": "2019-02-13T06:52:13.855000Z",
"methods": [
"password"
],
"catalog": [
{
"endpoints": [
{
"region_id": "aaa",
......
If an error occurs during API calling, the system returns an error code and a message to you. The following shows the format of an error response body:
{
"error_msg": "Parameter error",
"error_code": "DBS.200001"
}
In the preceding information, error_code is an error code, and error_msg describes the error.
