Gateway网关---Predicate断言配置

After

判断时间在After配置的时间之后规则才生效

spring: cloud: gateway: routes: - id: after_route uri: https://example.org predicates: - After=2017-01-20T17:42:47.789-07:00[America/Denver]

Before

判断在Before之前路由配置才生效

spring: cloud: gateway: routes: - id: before_route uri: https://example.org predicates: - Before=2017-01-20T17:42:47.789-07:00[America/Denver]

Between

在时间之内规则生效

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]

Cookie

带cookie，名字和正则表达式 cookie中需要带有key并且符合value的正则表达式。不带cookie会404

spring: cloud: gateway: routes: - id: cookie_route uri: https://example.org predicates: - Cookie=key, value

Header

请求头文件中带key的名称时 X-Request-Id 值是正则表达式\d+（数字） 其他信息自己添加

spring: cloud: gateway: routes: - id: header_route uri: https://example.org predicates: - Header=X-Request-Id, \d+

Host

主机是yumbo.top或者huashengshu.top的子域名的规则生效，如果不带这个信息，则会返回404 头文件中设置 Host

spring: cloud: gateway: routes: - id: host_route uri: https://example.org predicates: - Host=**.yumbo.top,**.huashengshu.top

Method

请求方法要是配置中设置的GET或者POST路由才会生效

spring: cloud: gateway: routes: - id: method_route uri: https://example.org predicates: - Method=GET,POST

Path

请求路径要符合Path设置的规则路由才生效

spring: cloud: gateway: routes: - id: path_route uri: https://example.org predicates: - Path=/red/{segment},/blue/{segment}

Query

请求参数要包含green参数路由才生效

spring: cloud: gateway: routes: - id: query_route uri: https://example.org predicates: - Query=green

RemoteAddr

如果请求的远程地址是192.168.1.10，则此路由匹配。

spring: cloud: gateway: routes: - id: remoteaddr_route uri: https://example.org predicates: - RemoteAddr=192.168.1.1/24

Weight

这条路径将把80%的流量转发到weighthigh.org，并将20%的流量转发到weighlow.org 权重路由，按照权重分流量

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
