**一 代码位置**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch7-][https_github.com_cakin24_spring-cloud-code_tree_master_ch7-]3

**二 测试**

1 启动Eurek

2 启动client-a服务

3 启动client-b服务

4 修改启动配置，启动zuul-server

spring:
      profiles:
        active: example1

测试下面路径

zuul:
      routes:
        client-a: /client/**

浏览器输入： [http://localhost:5555/client/mul?a=1&b=2][http_localhost_5555_client_mul_a_1_b_2]

结果输出： client-a-2

它是一个从/client/\*\*到client-a服务的一个映射规则

5 修改启动配置，启动zuul-server

spring:
      profiles:
        active: example2

测试下面配置

zuul:
      routes:
        client-a:

浏览器输入： [http://localhost:5555/client-a/mul?a=1&b=3][http_localhost_5555_client-a_mul_a_1_b_3]

结果输出： client-a-3

它是一个从/client-a/\*\*到client-a服务的一个映射规则

6 修改启动配置，启动zuul-server

spring:
      profiles:
        active: example4

测试下面配置

zuul:
      routes:
        client-b:
          path: /client/**
          serviceId: client-b
        client-a:
          path: /client/**
          serviceId: client-a

浏览器输入： [http://localhost:5555/client/mul?a=3&b=3][http_localhost_5555_client-a_mul_a_1_b_3]

结果输出： client-a-9

如果同一个映射对应多个服务，按照加载顺序，最后加载的映射规则会把之前的映射规则覆盖掉。

7 修改启动配置，启动 启动zuul-server

spring:
      profiles:
        active: example5

测试下面配置

########################## 敏感头设置 ##########################
    zuul:
      prefix: /pre
      routes:
        client-a:
          path: /client/**
    #      sensitiveHeaders: Cookie,Set-Cookie,Authorization
          sensitiveHeaders: Set-Cookie,Authorization
          serviceId: client-a
    #      stripPrefix: false

浏览器输入：[http://localhost:5555/pre/client/mul?a=3&b=4][http_localhost_5555_pre_client_mul_a_3_b_4]

测试结果为：client-a-12

8 修改启动配置，启动 zuul-server

spring:
      profiles:
        active: example7

测试下面配置

########################## 使用url替代serviceId路由  ##########################
    zuul:
      routes:
        client-a:
          path: /client/**
          url: http://localhost:7070 #client-a的地址

浏览器输入： [http://localhost:5555/client/mul?a=3&b=4][http_localhost_5555_pre_client_mul_a_3_b_4]

输出结果为： client-a-12

9 修改启动配置，启动 zuul-server

spring:
      profiles:
        active: example8

测试下面配置

########################## 脱离eureka让zuul结合ribbon实现路由负载均衡  ##########################
    zuul:
      routes:
        ribbon-route:
          path: /ribbon/**
          serviceId: ribbon-route
    
    ribbon:
      eureka:
        enabled: false  #禁止Ribbon使用Eureka
    ribbon-route:
      ribbon:
        NIWSServerListClassName: com.netflix.loadbalancer.ConfigurationBasedServerList
        NFLoadBalancerRuleClassName: com.netflix.loadbalancer.RandomRule     #Ribbon LB Strategy
        listOfServers: localhost:7070,localhost:7071     #client services for Ribbon LB

浏览器多次输入： [http://localhost:5555/ribbon/mul?a=3&b=4][http_localhost_5555_ribbon_mul_a_3_b_4]

结果分别为：

client-b-12
    client-b-12
    client-a-12
    client-b-12
    client-a-12
    client-b-12
    client-a-12

结果随机输出

10 修改启动配置，启动 zuul-server

spring:
      profiles:
        active: example9

测试下面配置

########################## foward跳转本地url  ##########################
    zuul:
      routes:
        client-a:
          path: /client/**
          url: forward:/client

浏览器输入： [http://localhost:5555/client?a=3&b=4][http_localhost_5555_client_a_3_b_4]

结果输出： 本地跳转：7
