## 基础网关服务

### 服务应用信息

| 服务名   | 类型                   | 端口 | 说明     |

| -------- | ---------------------- | ---- | -------- |

| gateway  | oauth2-client          | 8080 |          |

| resource | oauth2-resource-server | 9000 | 实际接口 |

### 配置

- 去除路径前缀

```java

class RouteLocatorConfig {

    public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {

        // 路径路由，去除前缀

        // http://localhost/get/users/toquery -> https://api.github.com/users/toquery

        // http://localhost/rewrite/get -> http://httpbin.org:80/get

        builder.routes().route("path_rewrite_route", r -> r.path("/rewrite/**")

                .filters(f -> f.rewritePath("/rewrite/(?.*)", "/${path}"))

                .uri(uri)

        ).build();

    }

}

```

- 添加接口的权重和负载均衡

```yaml

spring:

  application:

    name: cloud-gateway

  cloud:

    gateway:

      routes:

      - id: service1_prod

        uri: http://localhost:8081

        predicates:

        - Path=/test

        - Weight=service1, 50

      - id: service1_canary

        uri: http://localhost:8082

        predicates:

        - Path=/test

        - Weight=service1, 50

```

## 基于 Oauth2 的 SSO 认证授权网关

Spring 官方原文：[https://spring.io/blog/2019/08/16/securing-services-with-spring-cloud-gateway](https://spring.io/blog/2019/08/16/securing-services-with-spring-cloud-gateway)

### Oauth2 角色说明

- server

- client

### 服务与端口

| 服务名       | 类型                   | 端口 | 说明     |

| ------------ | ---------------------- | ---- | -------- |

| uaa          | oauth2-server          | 8090 |          |

| sso-gateway  | oauth2-client          | 8080 |          |

| sso-resource | oauth2-resource-server | 9000 | 资源服务 |

### 快速使用

```bash

./build-images.sh

docker-compose up

```

In an INCOGNITO or PRIVATE browser window...

[http://localhost:8080/resource](http://localhost:8080/resource)

You'll be asked to login, use Username: `user1` and Password: `password`.

> These credentials are configured in the `[sso/uaa/uaa.yml](sso/uaa/uaa.yml)` file.

You'll be asked to Authorise that the resource-server is allowed to read your profile and check your scopes. 

Click "Authorise` to allow this. You'll then be redirected to your original destination and the resource server 

will print out your Subject's identity GUID.

> Resource was accessed by a584b8b8-eaf2-4280-b9c3-12f65cf8524b (sub)

### Cleaning Up

When you're done use `Ctrl-C` to stop the containers, `docker-compose down` to remove leftovers. `docker-compose rm -f`

### Want to go again? 

Probably have to clear your cookies and restart the Docker bits...
