Spring云网关路由不起作用

Question

我正在使用Spring Cloud(hoxton.sr10)和Spring Boot(2.2.6.release)

我在尤里卡服务器8761注册了我的服务

# profil DEV

spring:
  profiles: dev

  cloud:
    gateway:
      routes:

          uri: http://localhost:8086/
          predicates:
           - Path=/api/**

This application has no explicit mapping for /error, so you are seeing this as a fallback.

我最终通过在配置文件中添加cors-configuration解决了我的问题。

spring:
   cloud:
          gateway:
      default-filters:
        - DedupeResponseHeader=Access-Control-Allow-Origin
      globalcors:
        cors-configurations:
          "[/**]":
            allowCredentials: true
            allowedOrigins: "*"
            allowedHeaders: "Origin, X-Requested-With, Content-Type, Accept, Content-Length, TOKEN, Authorization"
            allowedMethods: "GET, POST, PATCH, PUT, DELETE, OPTIONS"
            maxAge: 3628800
