使用HttpClient4调用rabbitmq rest api代码示例

package com.gsafety.rabbitmq.api;

import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

/**

public class RabbitRestTool {

    public static void main(String[] args) throws IOException {
        HttpHost host = new HttpHost("localhost", 15672);
 　　　　HttpGet httpGet = new HttpGet("/api/connections");
 　　　　//认证
　　　　 BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
　　　　 credentialsProvider.setCredentials(new AuthScope("localhost",15672),new UsernamePasswordCredentials("guest","guest"));
 　　　　CloseableHttpClient client = HttpClients.custom().setDefaultCredentialsProvider(credentialsProvider).build();

 　　　　HttpResponse response = client.execute(host, httpGet);

　　　　 HttpEntity entity = response.getEntity();
　　　　 String s = EntityUtils.toString(entity);
　　　　 System.out.println(s);
 }
}
