springboot和flask整合nacos，使用openfeign实现服务调用，使用gateway实现网关的搭建（附带jwt续约的实现）

环境准备：

插件	版本
jdk	21
springboot	3.0.11
springcloud	2022.0.4
springcloudalibaba	2022.0.0.0
nacos	2.2.3（稳定版）
python	3.8

nacos部署（docker）

先创建目录，分别创建config，logs，data目录，单独创建一个容器

docker run -d \
-e MODE=standalone \
-p 8848:8848 \
-p 9848:9848 \
-p 7848:7848 \
-v /data/nacos/conf:/mnt/data3/dockerfiles/nacos/config \
-v /data/nacos/logs:/mnt/data3/dockerfiles/nacos/logs \
-v /data/nacos/data:/mnt/data3/dockerfiles/nacos/data \
--name nacos-mysql \
--restart=always \
nacos/nacos-server:v2.2.3

将配置文件拷贝出来(主要是application.properties和logback.xml)

docker cp nacos-mysql:/home/nacos/conf ./

修改mysql的信息（修改文件application.properties）

再次运行

docker run -d \
-e MODE=standalone \
-p 8848:8848 \
-p 9848:9848 \
-p 7848:7848 \
-v /data/nacos/conf:/mnt/data3/dockerfiles/nacos/config \
-v /data/nacos/logs:/mnt/data3/dockerfiles/nacos/logs \
-v /data/nacos/data:/mnt/data3/dockerfiles/nacos/data \
--name nacos-mysql \
--restart=always \
nacos/nacos-server:v2.2.3

开启服务器端口：

centos开启防火墙端口

访问 ip:port/nacos

出现此页面即为安装成功。

配置文件bootstrap.yml

spring:
  application:
    name: platform
  cloud:
    nacos:
      server-addr: ip:port
      config:
        file-extension: yml
        group: DEFAULT_GROUP
        prefix: ${sping.application.name}

springboot启动类

@SpringBootApplication
@EnableFeignClients
@EnableCaching
@EnableScheduling
@EnableDiscoveryClient
@RefreshScope
public class PlatformApplication {

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

}

启动后就可以将服务注册到nacos中

python集成flask注册到nacos

首先下载nacos的sdk包

pip install nacos-sdk-python

python代码

import glob
import nacos
import threading
from flask import request, send_file
from flask import Flask, Response

# nacos注册中心配置
SERVER_ADDRESS = "http://ip:port"
client = nacos.NacosClient(SERVER_ADDRESS)


def service_register():
    """
     ephemeral参数：是否是临时服务，应为false; 
     刚才上面也提到了，如果是 非临时实例，客户端就无需主动完成心跳检测。
     因此此处将服务注册为 非临时实例
    """
    client.add_naming_instance(
        "train", "ip", "port", ephemeral=False)

# 测试nacos
@app.route("/testNacos/<testId>", methods=["GET"])
def testNacos(testId):
    resMap = {}
    print("nacos: {}".format(testId))
    resMap["code"] = "200"
    resMap["message"] = "hello nacos"
    resMap["data"] = str(testId)
    response = Response(json.dumps(resMap), status=200,
                        content_type='application/json')
    return response

if __name__ == "__main__":
    # main()
    threading.Timer(5, service_register).start()
    app.run("0.0.0.0", 12352)

启动后就可以将服务注册到nacos中

到这里，服务注册到nacos已经完成了

使用openfeign进行服务间的调用

@FeignClient("train")
public interface InferRpcService {

    @GetMapping("/testNacos/{testId}")
    VitsResponse testNacos(@PathVariable String testId);
}

测试类

@Test
public void testNacosPy(){
    System.out.println(trainService.testNacos("232323"));
}

执行后

经测试没有问题

                ServerHttpRequest modifiedRequest = exchange.getRequest()
                        .mutate()
                        .header("openId", openid)
                        .build();
                return chain.filter(exchange.mutate().request(modifiedRequest).build());
            } else {
                DecodedJWT verify = JWTUtils.verify(token);
                String openid = verify.getClaims().get("openid").asString();
                log.info("当前需要续约的jwtToken的用户手机号码: {}", openid);
                token = JWTUtils.doRenewed(openid);
                response.getHeaders().set(LoginConstant.AUTHORIZATION_HEADER, token);
                ServerHttpRequest modifiedRequest = exchange.getRequest()
                        .mutate()
                        .header("openId", openid)

                return chain.filter(exchange.mutate().request(modifiedRequest).build());
            }
        }
        return chain.filter(exchange);
    }

    @Override
    public int getOrder() {
        return -900;
    }

}

常量类

public interface Constant {

    String TOKEN = "token";
}

public interface LoginConstant {

    String LOGIN_PATH = "/login";

    String AUTHORIZATION_HEADER = "token";
}

public interface VitsCloneConstant {

    String API_PREFIX="/api/platform/";
}

启动网关后，就可以通过网关访问服务了

springboot和flask整合nacos，使用openfeign实现服务调用，使用gateway实现网关的搭建（附带jwt续约的实现）

环境准备：

nacos部署（docker）

springboot注册到nacos

python集成flask注册到nacos

使用openfeign进行服务间的调用

gateway网关服务

jwt续约
