Token Authentication

Scenarios

To use token authentication, you need to obtain a token and add X-Auth-Token to the request header when making API calls.

You can use either of the following authentication modes to call APIs.

• Token authentication: Requests are authenticated using a token.
• AK/SK authentication: Requests are encrypted using an AK/SK.

Calling an API Through Token Authentication

1. Obtain a token.

   For details, see Obtaining a User Token in the Identity and Access Management (IAM) API Reference.

   The token is the value of X-Subject-Token in the response.

   The following is an example request:

   POST https://{iam_endpoint}/v3/auth/tokens
   Content-Type: application/json
   
   {
       "auth": {
           "identity": {
               "methods": [
                   "password"
               ],
               "password": {
                   "user": {
                       "name": "username",
                       "password": "********",
                       "domain": {
                           "name": ""
                       }
                   }
               }
           },
           "scope": {
               "project": {
                   "id": "xxxxxxxx"
               }
           }
       }
   }

   In the preceding command:

   • For details about {iam_endpoint}, see "Regions and Endpoints".
   • username indicates the username.
   • indicates the account name of the user.
   • ******** indicates the login password of the user.
   • xxxxxxxx indicates the project ID.

     On the management console, click the username in the upper right corner, choose My Credentials from the drop-down list, and then view the project ID.

2. To call a service API, add X-Auth-Token to the request header. The value of X-Auth-Token is that of the token obtained in 1.
