## README

#### 介绍
电梯分布式服务端  

#### 软件架构  
软件架构说明  
springCloud Greenwich.SR1 版本  
spring boot 2.1.5.RELEASE 版本  
nacos  注册中心，配置中心  
skywalking  链路跟踪  
SpringCloud Gateway 网关  
Hystrix  熔断  
RedisRateLimit  基于redis的令牌桶限流  
ribbon   负载  
feign    微服务间调用（自带ribbon）  
mysql    数据库  
mybatis  orm  
redis    缓存  

#### 目录  
目录说明  
baasp-gateway模块  是网关模块  
baasp-backend模块  是后管模块（业务代码）  
#baasp-base模块     是基础模块，放公共方法/实体，以jar包形式被依赖，不可单独启动
#baasp-oauth模块    权限认证模块  

#移动原来的token校验到gateway模块AuthFilter.java     
#移动原来的跨域配置到gateway模块CorsConfig.java    
#后台加入druid监控模块 localhost:8088/druid。用户密码admin,admin   
#移动原有解密模块到gateway模块ParamFilter.java    
#Ureport不能启动加载，否则注册不到注册中心上(待解决)   

#### 启动说明   
backend、gateway 都能单独启动   
如果想从网关访问业务模块，gateway必须启动，并且可以手动增加路由，(后面优化启动时候加载， 下面有动态路由说明)   


#### 安装教程
本地运行需要  
1. 本地安装nacos      
2. 本地安装redis     ./redis-server  redis.conf  

上生产需要做集群  

#### 使用说明
1. 动态路由  
  
    网关上的已有方法
    新增路由  
    ```http request
    POST http://localhost:9090/route/add 
    ```
    更新路由  
    ```http request
    POST http://localhost:9090/route/update  
    ```
    删除路由  
    ```http request
    GET http://localhost:9090/route/delete/backend  
    ```
    
    新增路由 请求参数

        "predicates": [
            {

                    "methods": "POST"
                }
            }
        ],
        "uri": "lb://baasp-backend",

            {

                    "_genkey_0": "/api/baasp-oauth/**"
                }
            }
        ],
        "filters": [
            {
                "name": "StripPrefix",
                "args": {
                    "_genkey_0": "2"
                }
            },
            {
                "name": "RequestRateLimiter",
                "args": {
                    "key-resolver": "#{@hostAddrKeyResolver}",
                    "redis-rate-limiter.replenishRate": "1",
                    "redis-rate-limiter.burstCapacity": "1"
                }
            },
            {
                "name": "Hystrix",
                "args": {
                    "name": "fallbackcmd",
                    "fallbackUri": "forward:/fallback"
                }
            },
            {
                "name": "Retry",
                "args": {
                    "retries": "3",
                    "statuses": "BAD_GATEWAY",
                    "methods": "POST"
                }
            }
        ],
        "uri": "lb://baasp-oauth",
        "order": 0       
     }  
     
    基于actuator的  
    刷新路由  
    ```http request
    GET http://localhost:9090/actuator/gateway/refresh 
    ```
    查看所有路由  
    ```http request
    GET http://localhost:9090/actuator/gateway/routes  
    ```
    查看单个路由  
    ```http request
    GET http://localhost:9090/actuator/gateway/routes/{id}  
    ```

    ```http request  
    https://nacos.io/zh-cn/docs/quick-start.html  
    ```  
    ```http request
