我在使用consul作为服务发现的微服务设置中将spring cloud网关用作API网关。
在某些情况下,某些微服务的API需要2分钟以上的时间,网关会抛出以下错误:

我多次尝试了相同的API,恰好在2分钟后收到此错误。
是否有任何属性设置。版本和依赖项详细信息:

下游服务出现问题。
在我的应用程序中,nodejs 应用程序在 Spring Cloud Gateway 后面运行,默认超时为 2 分钟。
参考:https: //github.com/expressjs/express/issues/3330
在我的例子中,2 分钟后,nodejs 应用程序超时,这就是我在网关中收到错误的原因。
我通过更改节点应用程序中的超时值解决了这个问题
