okhttp 通过网关请求服务端返回数据

1、启动类代码

package com.tycoon.service;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**

 * Title： ServerConsume1Application

 * Description: 服务启动类

 *

 * @author tycoon

 * @version 1.0.0

 * @date 2019-02-26 10:10

 */

@EnableDiscoveryClient

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

public class ServerApplication {

    public static void main(String[] args) {

        SpringApplication.run(ServerApplication.class, args);

    }

}

2、 application.xml文件

spring:

  application:

    name: client-request

server:

  port: 7777  #访问项目端口

  servlet:

    context-path: /  #访问项目名称

  tomcat:

    uri-encoding: UTF-8

logging:

  level:

    root: INFO

    org.springframework.cloud.sleuth: DEBUG

  main:

    allow-bean-definition-overriding: true

  cloud:

    consul:

      discovery:

        instance-id: ${spring.application.name}:${server.port}

        prefer-ip-address: true

        health-check-interval: 10s    #心跳检查时间间隔

        hostname: ${spring.application.name}

        service-name: ${spring.application.name}

        enabled: true

        health-check-path: /health    #心跳检查

      host: 127.0.0.1

      port: 8500

3、测试类代码

package com.tycoon.service;

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClientBuilder;

import org.apache.http.util.EntityUtils;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

 */

@RunWith(SpringRunner.class)

@SpringBootTest

public class ServiceDemoApplicationTests {

    @Test

    public void doGetTestOne() {

        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SSS");//设置日期格式

        String date = df.format(new Date());// new Date()为获取当前系统时间，也可使用当前时间戳

        System.out.println(date);

        // 获得Http客户端(可以理解为:你得先有一个浏览器;注意:实际上HttpClient与浏览器是不一样的)

        CloseableHttpClient httpClient = HttpClientBuilder.create().build();


        // 说明service-provider 为服务提供者，card为服务controller接口，cardId=123456 说的 传入参数

        String strUrl = "http://localhost:9992/api/service-provider/card?cardId=123456&accessToken=1222";

        // 创建Get请求

        HttpGet httpGet = new HttpGet(strUrl);

       // 响应模型

        CloseableHttpResponse response = null;

        try {

            // 由客户端执行(发送)Get请求

            response = httpClient.execute(httpGet);

            // 从响应模型中获取响应实体

            HttpEntity responseEntity = response.getEntity();

            String date1 = df.format(new Date());

            System.out.println("响应状态为:" + response.getStatusLine()+" ,当前时间:"+date1);

            System.out.println();

            if (responseEntity != null) {

                System.out.println("响应内容为:" + EntityUtils.toString(responseEntity));

            }

        } catch (Exception e) {

            e.printStackTrace();

        } finally {

            try {

                // 释放资源

                if (httpClient != null) {

                    httpClient.close();

                }

                if (response != null) {

                    response.close();

                }

            } catch (IOException e) {

                e.printStackTrace();

            }

        }

    }

}
