5.2. 使用 REST API 进行身份验证

流程

1. 在命令行终端上，使用 OFFLINE_TOKEN 设置 API_TOKEN 变量来验证用户。

   $ export API_TOKEN=$( \
     curl \
     --silent \
     --header "Accept: application/json" \
     --header "Content-Type: application/x-www-form-urlencoded" \
     --data-urlencode "grant_type=refresh_token" \
     --data-urlencode "client_id=cloud-services" \
     --data-urlencode "refresh_token=${OFFLINE_TOKEN}" \
     "https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token" \
     | jq --raw-output ".access_token" \
   )

2. 确认 API_TOKEN 变量定义：

   $ echo ${API_TOKEN}

3. 在您的路径中为令牌生成方法创建一个脚本。例如：

   $ vim ~/.local/bin/refresh-token

   export API_TOKEN=$( \
     curl \
     --silent \
     --header "Accept: application/json" \
     --header "Content-Type: application/x-www-form-urlencoded" \
     --data-urlencode "grant_type=refresh_token" \
     --data-urlencode "client_id=cloud-services" \
     --data-urlencode "refresh_token=${OFFLINE_TOKEN}" \
     "https://sso.redhat.com/auth/realms/redhat-external/protocol/openid-connect/token" \
     | jq --raw-output ".access_token" \
   )

   然后保存文件。

4. 更改文件模式使其可执行：

   $ chmod +x ~/.local/bin/refresh-token

5. 刷新 API 令牌：

   $ source refresh-token

6. 运行以下命令验证您可以访问 API：

   $ curl -s https://api.openshift.com/api/assisted-install/v2/component-versions -H "Authorization: Bearer ${API_TOKEN}" | jq

   输出示例

   {
     "release_tag": "v2.11.3",
     "versions": {
       "assisted-installer": "registry.redhat.io/rhai-tech-preview/assisted-installer-rhel8:v1.0.0-211",
       "assisted-installer-controller": "registry.redhat.io/rhai-tech-preview/assisted-installer-reporter-rhel8:v1.0.0-266",
       "assisted-installer-service": "quay.io/app-sre/assisted-service:78d113a",
       "discovery-agent": "registry.redhat.io/rhai-tech-preview/assisted-installer-agent-rhel8:v1.0.0-195"
     }
   }
