用java代码实现寻息®位置物联⽹开放平台获取MQ消息队列

在Java中，使用寻息®位置物联⽹开放平台获取MQ消息队列通常需要通过API客户端库或者是直接编写HTTP请求来进行。这里是一个基本的示例，展示如何使用Spring框架以及Apache HttpClient库来发送GET请求获取消息：

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;

public class MQMessageClient {
    private static final String API_URL = "your-MQ-endpoint"; // 替换为实际的MQ服务URL
    private static final String ACCESS_TOKEN = "your-access-token"; // 替换为你的访问令牌

    public void getMessageFromQueue() throws Exception {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        HttpGet httpGet = new HttpGet(API_URL + "?access_token=" + ACCESS_TOKEN);

        HttpResponse response = httpClient.execute(httpGet);
        int statusCode = response.getStatusLine().getStatusCode();

        if (statusCode == 200) {
            // 处理返回的消息数据
            String responseBody = EntityUtils.toString(response.getEntity());
            System.out.println("Received message: " + responseBody);
        } else {
            throw new RuntimeException("Failed to fetch message, status code: " + statusCode);
        }

        httpClient.close(); // 关闭连接
    }
}

记得将`your-MQ-endpoint`和`your-access-token`替换为你实际的平台地址和授权信息。
