我在 ec2 上运行我的简单类以在 SQS 上创建或发送消息。但这给了我服务：AmazonSQS；状态码：403；错误代码：SignatureDoesNotMatch；

我附上了我的代码和以下错误：-

private AWSSimpleQueueServiceUtil() {
    try {
        this.simpleQueue = "demo-Photo-Queue";
        //this.sqs = (AmazonSQS) AmazonSQSClientBuilder.standard().build();
        //this.sqs.setEndpoint("https://a4b.us-east-1.amazonaws.com");
        this.sqs = (AmazonSQS)  AmazonSQSClientBuilder.standard()
        .withRegion(Regions.US_EAST_1)
        .build();

    } catch (Exception e) {
        System.out.println("exception while creating awss3client : " + e);
    }
}

public static AWSSimpleQueueServiceUtil getInstance() {
    return awssqsUtil;
}

public AmazonSQS getAWSSQSClient() {
    return awssqsUtil.sqs;
}

public String getQueueName() {
    return awssqsUtil.simpleQueue;
}

/**
 * Creates a queue in your region and returns the url of the queue
 * 
 * @param queueName
 * @return
 */
public String createQueue(String queueName) {
    CreateQueueRequest createQueueRequest = new CreateQueueRequest(queueName);
    String queueUrl = this.sqs.createQueue(createQueueRequest).getQueueUrl();
    return queueUrl;
}

/**
 * returns the queueurl for for sqs queue if you pass in a name
 * 
 * @param queueName
 * @return
 */
public String getQueueUrl(String queueName) {
    GetQueueUrlRequest getQueueUrlRequest = new GetQueueUrlRequest(queueName);
    return this.sqs.getQueueUrl(getQueueUrlRequest).getQueueUrl();
}

/**
 * send a single message to your sqs queue
 * 
 * @param queueUrl
 * @param message
 */
public void sendMessageToQueue(String queueUrl, String message) {
    SendMessageResult messageResult = this.sqs.sendMessage(new SendMessageRequest(queueUrl, message));
    System.out.println(messageResult.toString());
    System.out.println("send successfully");
}

public static void main(String[] args) throws UnsupportedEncodingException {
    //String thePath = "https://sqs.us-east-1.amazonaws.com/685308457175/demo-Photo-Queue";
    String queueName = "myFisrtQueue";
    queueName = URLEncoder.encode(queueName, "UTF-8");
    System.out.println(queueName);
    AWSSimpleQueueServiceUtil.getInstance().createQueue("queueName");

}

以下是我收到的错误：-
