新建 mingyue-gateway

在 【从零搭建微服务-注册中心（二）】中就建好了模块

核心依赖

<dependency>
  <groupId>org.springframework.cloudgroupId>
  <artifactId>spring-cloud-starter-gatewayartifactId>
dependency>


<dependency>
  <groupId>org.springframework.cloudgroupId>
  <artifactId>spring-cloud-starter-loadbalancerartifactId>
dependency>

核心配置

保存到 application.yml 或 nacos 中都可以

spring:
    cloud:
        # 网关配置
        gateway:
            # 打印请求日志(自定义)
            requestLog: true
            discovery:
                locator:
                    enabled: true
            routes:
                # 认证中心
                - id: mingyue-auth
                  uri: lb://mingyue-auth
                  predicates:
                      - Path=/auth/**
                  filters:
                      - StripPrefix=1

测试网关

启动 mingyue-auth

直接调用登录接口: http://localhost:9000/oauth2/token

curl --location --request POST 'http://localhost:9000/oauth2/token?grant_type=password&client_id=1001&client_secret=aaaa-bbbb-cccc-dddd-eeee&username=sa&password=123456' \
--header 'User-Agent: Apifox/1.0.0 (https://www.apifox.cn)' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--header 'Host: localhost:9000' \
--header 'Connection: keep-alive'

返回结果：

{
    "code": 200,
    "msg": "ok",
    "data": {
        "access_token": "xHJR3aIsYOZxZiCpbXzDjKMS32JfLV2m5jtme1gEsItvKR8ZiEZ3GUVkJBom",
        "refresh_token": "O0SmM1Pb7MP18rE7Uz72MIY9uucCTBnAJ2CkWXCq4FeaTU7o8e0BPExfvQGX",
        "expires_in": 7199,
        "refresh_expires_in": 2591999,
        "client_id": "1001",
        "scope": "",
        "openid": "gr_SwoIN0MC1ewxHX_vfCW3BothWDZMMtx__"
    }
}

启动 mingyue-gateway

间接调用（通过网关）登录接口：http://localhost:9100/auth/oauth2/token

curl --location --request POST 'http://localhost:9100/auth/oauth2/token?grant_type=password&client_id=1001&client_secret=aaaa-bbbb-cccc-dddd-eeee&username=sa&password=123456' \
--header 'User-Agent: Apifox/1.0.0 (https://www.apifox.cn)' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--header 'Host: localhost:9100' \
--header 'Connection: keep-alive' \
--header 'Cookie: Authorization=d7dc6f87-bf4a-4903-ad6c-2ac668f5e5a7'

返回结果：

{
    "code": 200,
    "msg": "ok",
    "data": {
        "access_token": "PRMy2RJXTA8SAtHChWLXYRHfANQiOeFPxyfilCdUnz8j0oZrnpXZqkkh06BB",
        "refresh_token": "najLtYrf2SZhtsayHTKEeG5yVeZEmcgu7ePVf00C8QcX0uVjh8yw2SaH8INP",
        "expires_in": 7199,
        "refresh_expires_in": 2591999,
        "client_id": "1001",
        "scope": "",
        "openid": "gr_SwoIN0MC1ewxHX_vfCW3BothWDZMMtx__"
    }
}

改造 mingyue-ui

1.修改 vite.config.ts

http://localhost:9000 => http://localhost:9100

'/api': {
					target: 'http://localhost:9100/',
					ws: true,
					changeOrigin: true,
					rewrite: (path) => path.replace(/^\/api/, ''),
},

2.修改登录相关接口地址

src/api/login/index.ts

signIn: (data: object) => {
			let client_id = 1001;
			let grant_type = 'password';
			let client_secret = 'aaaa-bbbb-cccc-dddd-eeee';
			// TODO 规范入参类型
			let username = data.username;
			let password = data.password;

			return request({
				url: '/api/auth/oauth2/token',
				method: 'post',
				params: {grant_type, client_id, client_secret, username, password}
			});
		},
signOut: () => {
			let client_id = 1001;
			let client_secret = 'aaaa-bbbb-cccc-dddd-eeee';
			let access_token = Session.get('token');

			// 调用回收 Access-Token 接口
			return request({
				url: '/api/auth/oauth2/revoke',
				method: 'post',
				params: {client_id, client_secret, access_token}
			});
		}

3.启动测试

可以登录、登出即可～

小结

至此，我们已经完成了 mingyue-ui => mingyue-gateway => mingyue-auth，如下图流程所示：

接下来，我们我们开始编写 mingyue-system 用户相关模块，改造 mingyue-auth 用户查询走数据库。
