春云网关拒绝查询参数

Question

我开始设置一个Spring Cloud Gateway，它在uri中没有查询参数的情况下工作得很好。但是我需要一些参数，它们不是固定的，我不使用它们来选择路由，我只需要它们和uri一起发送，没有任何改变。

例如，网址：

http://localhost:8080/dev/select config/v1/ABCDE

可以工作，但对于查询参数，它不会：

http://localhost:8080/dev/selectconfig/v1/ABCDE?config={"高度"： 22，"宽度"： 30}

我收到 400 错误请求。我想重定向到网址：

https://somehosthere.com/dev/selectconfig/v1/ABCDE?config={ "高度":22，"宽度":30}

spring:
  cloud:
    gateway:
      routes:
      - id: route1
        uri: https://somehosthere.com/
        predicates:
        - Path=/dev/selectconfig/**
        filters:
        - AddRequestHeader=SOMEKEY, ${SOMEKEY}

请尝试此配置

spring:
  cloud:
    gateway:
      routes:
      - id: route1
        uri: https://somehosthere.com/
        predicates:
        - Path=/dev/selectconfig/**
        - Query=config
        filters:
        - AddRequestHeader=SOMEKEY, ${SOMEKEY}   

   

请注意查询谓词。如果要更好地控制查询参数值，可以添加正则表达式。有关更多详细信息，请参阅此链接
