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 1\ *xx* to 5\ *xx*. It indicates the status of a request. For more information, see :ref:`Status Codes <mrs_02_0015>`.
|
|
|
|
For the API to `obtain request authentication <https://docs.otc.t-systems.com/en-us/api/iam/en-us_topic_0057845583.html>`__, if the status code **201** is returned after the API is called, the request is successful.
|
|
|
|
Response Header
|
|
---------------
|
|
|
|
Similar to a request, a response also has a header, for example, **Content-Type**.
|
|
|
|
:ref:`Figure 1 <mrs_02_0010__en-us_topic_0170155703_fig4865141011511>` shows the response header fields for the API used to `obtain request authentication <https://docs.otc.t-systems.com/en-us/api/iam/en-us_topic_0057845583.html>`__. The **x-subject-token** header field is the desired user token. This token can then be used to authenticate the calling of other APIs.

|
(Optional) Response Body
|
|
------------------------
|
|
|
|
This part is optional. The body of a response is often returned in structured format (for example, JSON or XML) as specified in the **Content-Type** header field. The response body transfers content except the response header.
|
|
|
|
The following shows the response body for the API to `obtain request authentication <https://docs.otc.t-systems.com/en-us/api/iam/en-us_topic_0057845583.html>`__. For the sake of space, only part of the content is displayed here.

|
.. code-block::
|
|
|
|
{
|
|
"token": {
|
|
"expires_at": "2019-02-13T06:52:13.855000Z",
|
|
"methods": [
|
|
"password"
|
|
],
|
|
"catalog": [
|
|
{
|
|
"endpoints": [
|
|
{
|
|
"region_id": "aaa"//The region ID "aaa" is used as an example.
|
|
...
|
|
|
|
If an error occurs during API calling, an error code and a message will be displayed. The following shows an error response body.
|
|
|
|
.. code-block::
|
|
|
|
{
|
|
"error_msg": "Invalid cluster name.",
|
|
"error_code": "12000002"
|
|
}
|
|
|
|
In the response body, **error_code** is an error code, and **error_msg** provides information about the error.
