Authentication
API calling requests must be authenticated using tokens.
Token Authentication
![](https://support.huaweicloud.com/intl/en-us/api-msgsms/public_sys-resources/note_3.0-en-us.png)
The validity period of a token is 24 hours. When using a token for authentication, cache it to prevent frequently calling the IAM API for obtaining a user token.
A token specifies temporary permissions in a computer system. During API authentication using a token, the token is added to requests to get permissions for calling the API. Obtain it by calling the API for obtaining user token.
A cloud service can be deployed as either a project-level service or global service.
- For a project-level service, obtain a project-level token. When you call the API, set auth.scope in the request body to project.
- For a global service, obtain a global token. When you call the API, set auth.scope in the request body to domain.
Message & SMS is a project-level service. When you call the API for obtaining a user token, set auth.scope in the request body to project.
{ "auth": { "identity": { "methods": [ "password" ], "password": { "user": { "name": "username", "password": "********", "domain": { "name": "domainname" } } } }, "scope": { "project": { "name": "xxxxxxxx" } } } }
After a token is obtained, the X-Auth-Token header field must be added to requests to specify the token when calling other APIs. For example, if the token is ABCDEFJ...., X-Auth-Token: ABCDEFJ.... should be added to a request as follows:
1 2 3 |
POST https://iam.ap-southeast-1.myhuaweicloud.com/v3/auth/projects Content-Type: application/json X-Auth-Token: ABCDEFJ.... |
