QCloudCredentialProvider

直接已知子类:

SessionCredentialProvider, ShortTimeCredentialProvider

public abstract class BasicLifecycleCredentialProvider
extends java.lang.Object
implements QCloudCredentialProvider

基础的生命周期证书提供器
用于定义如何获取具有生命周期的证书QCloudLifecycleCredentials，
您可以自定义临时密钥服务的 HTTP 响应体，给终端返回服务器时间作为签名的开始时间，用来避免由于用户手机本地时间偏差过大导致的签名不正确，或者使用其他的协议来进行终端和服务端之间的通信。

getCredentials

public QCloudCredentials getCredentials()
                                 throws QCloudClientException

从接口复制的说明: QCloudCredentialProvider

Returns QCloudCredentials which the caller can use to authorize an QCloud request. Each implementation of QCloudCredentialsProvider can chose its own strategy for loading credentials. For example, an implementation might load credentials from an existing key management system, or load new credentials when credentials are rotated.

指定者:

getCredentials 在接口中 QCloudCredentialProvider

返回:

QCloudCredentials which the caller can use to authorize an QCloud request.

抛出:

QCloudClientException

refresh

public void refresh()
             throws QCloudClientException

从接口复制的说明: QCloudCredentialProvider

Forces this credentials provider to refresh its credentials. For many implementations of credentials provider, this method may simply be a no-op, such as any credentials provider implementation that vends static/non-changing credentials. For other implementations that vend different credentials through out their lifetime, this method should force the credentials provider to refresh its credentials.

指定者:

refresh 在接口中 QCloudCredentialProvider

抛出:

QCloudClientException

forceInvalidationCredential

public void forceInvalidationCredential()

强制让凭证失效

fetchNewCredentials

protected abstract QCloudLifecycleCredentials fetchNewCredentials()
                                                           throws QCloudClientException

请求一个新的临时密钥

返回:

一个有效的临时密钥

抛出:

QCloudClientException - 如果请求超时或者失败，会抛出异常
