Spring Cloud Gateway通过路由谓词工厂来进行路径规则配置
after配置只有一个时间参数,用于匹配指定时间之后的请求
spring:
cloud:
gateway:
routes:
- id: after_route
uri: https://example.org
predicates:
- After=2017-01-20T17:42:47.789-07:00[America/Denver]
after配置只有一个时间参数,用于匹配指定时间之前的请求
spring:
cloud:
gateway:
routes:
- id: before_route
uri: https://example.org
predicates:
- Before=2017-01-20T17:42:47.789-07:00[America/Denver]
after配置有两个时间参数,用于匹配指定时间范围之间的请求
spring:
cloud:
gateway:
routes:
- id: between_route
uri: https://example.org
predicates:
- Between=2017-01-20T17:42:47.789-07:00[America/Denver], 2017-01-21T17:42:47.789-07:00[America/Denver]
有两个参数,第一个为Cookie的name,第二个为匹配对应值的正则表达式,匹配符合条件的请求
spring:
cloud:
gateway:
routes:
- id: cookie_route
uri: https://example.org
predicates:
- Cookie=chocolate, ch.p
有两个参数,第一个为Header的name,第二个为匹配对应值的正则表达式,匹配符合条件的请求
spring:
cloud:
gateway:
routes:
- id: header_route
uri: https://example.org
predicates:
- Header=X-Request-Id, \d+
处理指定域名服务的请求
spring:
cloud:
gateway:
routes:
- id: host_route
uri: https://example.org
predicates:
- Host=**.somehost.org,**.anotherhost.org
通过HTTP方法来匹配
spring:
cloud:
gateway:
routes:
- id: method_route
uri: https://example.org
predicates:
- Method=GET,POST
通过请求路径匹配
spring:
cloud:
gateway:
routes:
- id: path_route
uri: https://example.org
predicates:
- Path=/red/{segment},/blue/{segment}
query用于包含指定参数值的请求,有两个参数,第一个是参数name,第二个是用于匹配值得正则表达式
spring:
cloud:
gateway:
routes:
- id: query_route
uri: https://example.org
predicates:
- Query=red, gree.
根据请求发起的IP进行拦截处理
spring:
cloud:
gateway:
routes:
- id: remoteaddr_route
uri: https://example.org
predicates:
- RemoteAddr=192.168.1.1/24
根据权重进行配置,一共两个参数,第一个是组名,第二个是在改组中的占比(相加为10)
spring:
cloud:
gateway:
routes:
- id: weight_high
uri: https://weighthigh.org
predicates:
- Weight=group1, 8
- id: weight_low
uri: https://weightlow.org
predicates:
- Weight=group1, 2
表示一个占比80%,一个占比20%
