Spring 当 header 用于 header 值路由时，集成将 X-* 添加到自定义 Headers

Question

我正在使用 header 值路由，在最终的网络服务中，用于 header 值路由的 header 附加了一个 X-* 字符串。

抓取的header如下：

GET /mapfre-tron-mobile/badgeCounters HTTP/1.1
Accept: */*
X-*routingCode: AB
X-*http_requestMethod: GET
X-*errorChannel:     org.springframework.messaging.core.GenericMessagingTemplate$TemporaryReplyChannel@c52014

如您所见，我将 routingCode 作为 header 传递，但它变成了 X-*routingCode:.

有什么想法吗？

Answer 1

您没有显示 headerMapper bean，但看起来您正在映射所有 header；这不太可能是正确的（例如 replyChannel），您应该更具体地说明正在映射哪些 header。

X-*... header 中的 * 看起来很奇怪 - 我猜还有一些其他错误的映射配置。

如果您不需要前缀（X- 是自定义 HTTP headers 的常见前缀），您可以在 header 映射器中取消它。

请将您的 header 映射器配置以及任何其他相关的上游配置添加到问题中。

一如既往，DEBUG 日志记录通常可以帮助解决此类情况。
