语音交互服务 SIS-认证鉴权:Token认证
Token认证
Token的有效期为24小时,需要使用同一个Token鉴权时,可以缓存起来,避免频繁调用。
Token在计算机系统中代表令牌(临时)的意思,拥有Token就代表拥有某种权限。Token认证就是在调用API的时候将Token加到请求消息头,从而通过身份认证,获得操作API的权限。
代码中加粗的斜体字段需要根据实际值填写username、domainname、project name,可登录控制台“我的凭证”页面获取。password为用户密码。
- 伪码
POST https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens Content-Type: application/json { "auth": { "identity": { "methods": [ "password" ], "password": { "user": { "name": "username", "password": "********", "domain": { "name": "domainname" } } } }, "scope": { "project": { "name": "cn-north-4" } } } }
- Python
import requests import json url = "https://iam.cn-north-4.myhuaweicloud.com/v3/auth/tokens" payload = json.dumps({ "auth": { "identity": { "methods": [ "password" ], "password": { "user": { "name": "username", "password": "********", "domain": { "name": "domainname" } } } }, "scope": { "project": { "name": "cn-north-4" } } } }) headers = { 'Content-Type': 'application/json' } response = requests.request("POST", url, headers=headers, data=payload) print(response.headers["X-Subject-Token"])
获取Token后,再调用其他接口时,您需要在请求消息头中添加“X-Auth-Token”的值。例如Token值为“ABCDEFJ....”,则调用接口时将“X-Auth-Token: ABCDEFJ....”加到请求消息头即可,如下所示。
Content-Type: application/json X-Auth-Token: ABCDEFJ....
