先訪問你的dashboard確認你的鑒權地址：

鑒權地址

postman構建請求：

請求

{
    "auth": {
        "identity": {
            "methods": ["password"],
            "password": {
                "user": {
                    "domain": {
                        "name": "Default"
                    },
                    "name": "admin",
                    "password": "nvframe"
                }
            }
        },
        "scope": {
            "project": {
                "domain": {
                    "name": "Default"
                },
                "name": "admin"
            }
        }
    }
}

響應：

{
    "token": {
        "is_domain": false,
        "methods": [
            "password"
        ],
        "roles": [
            {
                "id": "cb597116df024e14a7505d1f6fc1493a",
                "name": "reader"
            },
            {
                "id": "0d5dd712d4224ae8a29f09ab3b15ccd2",
                "name": "admin"
            },
            {
                "id": "aaf727fa2fd54525a212af47e28ebcad",
                "name": "member"
            }
        ],
        "expires_at": "2023-03-12T07:06:15.000000Z",
        "project": {
            "domain": {
                "id": "default",
                "name": "Default"
            },
            "id": "e69163760474442b97e9941b70e91a7b",
            "name": "admin"
        },
        "user": {
            "password_expires_at": null,
            "domain": {
                "id": "default",
                "name": "Default"
            },
            "id": "3a529e6e19b144bab3143f28e6a56591",
            "name": "admin"
        },
        "audit_ids": [
            "TDB5fhKxTPmvJG32mm0S5g"
        ],
        "issued_at": "2023-03-12T06:06:15.000000Z"
    }
}

但是實際上我們要拿的是返回的HEADERS里面的X-Subject-Token：

TOKEN

請求列表：

需要這個部分

postman請求：

請求樣例

以后每次請求都需要帶上這句token。
返回：

        {
