spring cloud ouath2 +getway跨域是有特别的配置的(与普通跨域不同)
1.bootstrap.yml
spring:
cloud:
gateway:
globalcors:
add-to-simple-url-handler-mapping: true
corsConfigurations:
'[/**]':
# 支持跨域访问的来源 也就是前台地址 可以配置多个 方法如下
allowedOrigins:
- "http://192.168.xx.xx:8080"
- "http://192.168.xx.xx:8080"
# 切记 allowCredentials 配置 为true时,allowedOrigins不能为 *
allowCredentials: true
maxAge: 86400
# 支持的方法 * 代表所有
allowedMethods: "*"
allowedHeaders: "*"
exposedHeaders: "setToken"
routes:
# 路由标识(id:标识,具有唯一性) 截取请求
- id: auth
# 目标服务地址(uri:地址,请求转发后的地址)
uri: lb://auth
# 路由条件(predicates:断言,匹配 HTTP 请求内容)
predicates:
## 转发地址格式为 uri/archive,/str 部分会被下面的过滤器给截取掉
- Path=/auth/**
