我正在尝试获取临时安全凭证并使用它们在 Kinesis 流上推送/发布数据。请检查以下代码以获取凭据。
private AssumeRoleResult getAssumeRoleResult() {
AssumeRoleResult assumeRoleResult = null;
try {
log.info("Started to fetch AssumeRoleResult");
BasicSessionCredentials currentRoleCredentials = getCredentialsOfCurrentRole();
String sessionName = "assumedRole_" + RandomStringUtils.randomAlphanumeric(5).toUpperCase();
region = Config.getRegion();
AWSSecurityTokenService sts = AWSSecurityTokenServiceClientBuilder.standard()
.withCredentials(new AWSStaticCredentialsProvider(currentRoleCredentials)).withRegion(region)
.build();
String roleArn = Configurations.ROLE_ARN;
assumeRoleResult = sts.assumeRole(new AssumeRoleRequest().withRoleArn(roleArn)
.withDurationSeconds(AWS_KINESIS_SESSION_DURATION)
.withRoleSessionName(sessionName));
log.info("Your AssumeRoleResult is" + assumeRoleResult.toString())
return assumeRoleResult;
} catch(Exception e) {
log.error("Failed to get AssumeRoleResult with error : {}", e.getMessage());
e.printStackTrace();
}
}
private BasicSessionCredentials getCredentialsOfCurrentRole() throws JSONException {
// Code to fetch IAM credentials for current role
}
但是当我检查日志时,发现assumeRoleResult没有返回任何东西。(我没有看到任何日志说“你的AssumeRoleResult 是”,也没有发现异常)。
你能告诉我这里可能有什么问题吗?
