Apache jClouds - 我們可以將身份驗證 keystone v3 與 application_credential 一起使用嗎？

Question

jClouds是否支持application_credential kesytone V3？

我正在使用 OpenStack，我想使用jClouds 2.2.1 ( https://specs.openstack.org/openstack/keystone-specs/specs/keystone/queens/application-credentials.html ) 的應用程序憑據身份驗證。

Keystone 模塊有一個名為application_credential的 auth 方法。 以下是 application_credential 的 POST 請求示例：

$ curl -i -H "Content-Type: application/json" -d \
'{
    "auth": {
        "identity": {
            "methods": [
                "application_credential"
            ],
            "application_credential": {
                "id": "50916383859f4d2f919c86315ffa17ba",
                "secret": "demo"
            }
        }
    }
}' \
"http://192.168.190.1:5000/v3/auth/tokens"

使用 Java，我有代碼：

Properties overrides = new Properties();

overrides.put(KeystoneProperties.KEYSTONE_VERSION, "3");
overrides.put(KeystoneProperties.CREDENTIAL_TYPE,
              CredentialTypes.API_ACCESS_KEY_CREDENTIALS);
    
String accessKey = "accessKey";
String accessSecret = "accessSecret";
     
KeystoneApi keystone = ContextBuilder.newBuilder("openstack-keystone-3")
        .endpoint("https://keystone.domain/v3")
        .credentials(accessKey, accessSecret)
        .overrides(overrides)
        .modules(ImmutableSet.of(new SLF4JLoggingModule(),
                                 new OkHttpCommandExecutorServiceModule()))
        .buildApi(KeystoneApi.class);
     
keystone.getProjectApi().list();

它拋出一個異常：

因為它不起作用，也許我錯過了一些東西 [1]： https://jclouds.apache.org/guides/openstack/
