AWS SNSClient 发布请求超时错误

发布请求超时错误是使用AWS SNSClient时可能遇到的一种常见问题。AWS SNSClient是Amazon Web Services (AWS)的一种服务，用于发送通知消息到多个终端设备或分发消息到多个接收者。然而，在发送请求时，有时候可能会遇到请求超时的错误。

java
import com.amazonaws.services.sns.AmazonSNS;
import com.amazonaws.services.sns.AmazonSNSClientBuilder;
import com.amazonaws.services.sns.model.PublishRequest;
import com.amazonaws.services.sns.model.PublishResult;
public class SNSClientExample {
    public static void main(String[] args) {
        // 创建AmazonSNS客户端
        AmazonSNS snsClient = AmazonSNSClientBuilder.standard().build();
        // 创建发布请求
        PublishRequest publishRequest = new PublishRequest()
                .withTopicArn("arn:aws:sns:us-west-2:123456789012:MyTopic")
                .withMessage("Hello, world!");
        try {
            // 发布消息
            PublishResult publishResult = snsClient.publish(publishRequest);
            System.out.println("Message published. MessageId: " + publishResult.getMessageId());
        } catch (Exception e) {
            System.err.println("Error publishing message: " + e.getMessage());
        }
    }
}
