SpringCloud服务治理（十九）集成其他语言

Spring Cloud Netflix Sidecar

1，导入依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-sidecar</artifactId>
</dependency>

2，启动配置

@EnableSidecar
@SpringBootApplication
public class SidecarApplication {

    public static void main(String[] args) {
        SpringApplication.run(SidecarApplication.class, args);
    }

}

3,配置文件

server:
  port: 5678
spring:
  application:
    name: sidecar
sidecar:
  port: 3000
  health-uri: http://localhost:${sidecar.port}/health
eureka:
  client:
    service-url:
      defaultZone: http://admin:pwd@localhost/eureka/

4，创建python项目

#!/usr/bin/python3
# -*- coding:utf-8 -*-
import json
from flask import Flask, Response
import requests


app = Flask(__name__)
@app.route("/health")
def health():
    result = {'status': 'UP'}
    return Response(json.dumps(result), mimetype='application/json')
@app.route("/getUser")
def getUser():
    result = {'username': 'python', 'password': 'python'}
    return Response(json.dumps(result), mimetype='application/json')
@app.route("/getJava")
def getJava():
    result = {'username': 'python', 'password': 'python'}
    url = 'http://localhost:5678/consumer1/java-user'  # django api路径

    parms = {
        'name': '客户端',  # 发送给服务器的内容
    }

    headers = {  # 请求头 是浏览器正常的就行 就这里弄了一天 - -！
        'User-agent': 'none/ofyourbusiness',
        'Spam': 'Eggs'
    }

    resp = requests.post(url, data=parms, headers=headers)  # 发送请求

    # Decoded text returned by the request
    text = resp.text
    # print(json.loads(text))

    return Response(json.dumps(text), mimetype='application/json')
app.run('0.0.0.0', 3000)
app.run(port=3000, host='0.0.0.0')

5，配置controller

@RestController
public class PythonController {

    @Autowired
    private RestTemplate restTemplate;
    @RequestMapping("/java-user")
    public String JavaUser() {
        return "{'username': 'java', 'password': 'java'}"  ;
    }
    @RequestMapping("/python-user")
    public String PythonUser() {
        return restTemplate.getForEntity("http://sidecar/getUser", String.class).getBody();
    }
}
