獲取臨時token

在服務端生成臨時token，可參考java、python、nodejs、CPP、donet、go、php SDK說明，請從 SDK概覽 頁面選擇進入對應的開發指南查閱。

使用臨時token

客戶端實現一個CredentialsProvider，支持更新ak/sk和token。

public class MyCredentialsProvider implements AWSCredentialsProvider {
    private AWSCredentials credentials;
?
    public MyCredentialsProvider(String ak, String sk, String token) {
        this.credentials = new BasicSessionCredentials(ak, sk, token);
    }
?
    public synchronized AWSCredentials getCredentials() {
        return credentials;
    }
?
    public synchronized void refresh() {
    }
?
    // 更新ak,sk,token
    public synchronized void updateCred(String ak, String sk, String token) {
        this.credentials = new BasicSessionCredentials(ak, sk, token);
    }
}

客戶端使用臨時token

String accessKey = "<your-access-key>";
String secretKey = "<your-secret-access-key>";
String endPoint = "<your-endpoint>";
String sessionToken = "<your-session-token>";          
?
MyCredentialsProvider credProvider = new MyCredentialsProvider(accessKey, secretKey, sessionToken);
ClientConfiguration clientConfig = new ClientConfiguration();
clientConfig.setProtocol(Protocol.HTTP);
AmazonS3Client mS3Client = new AmazonS3Client(credProvider, clientConfig);
mS3Client.setEndpoint(endPoint);
