类 SessionCredentialProvider

java.lang.Object

com.tencent.qcloud.core.auth.BasicLifecycleCredentialProvider

com.tencent.qcloud.core.auth.SessionCredentialProvider

所有已实现的接口:

QCloudCredentialProvider

public class SessionCredentialProvider
extends BasicLifecycleCredentialProvider

服务端临时证书提供器
搭建一个返回临时密钥的服务，即可给终端 COS 请求进行授权，我们强烈建议您使用这种方式，
具体请参见 移动应用直传实践

SDK 示例：方式一：通过临时密钥进行授权（推荐）
