java - 无效的握手响应 getStatus: 502 Bad Gateway

Question

我们有 OpenShift、Istio、Cloud-gateway 微服务、几个微服务。

• 春季启动 2.3.6.RELEASE，
• Spring-Cloud Hoxton.SR9
• Spring-Cloud-Starter-Gateway 2.2.6.RELEASE

我们的问题是：无效的 websocket 握手。

当我们从我们的集合中排除 Istio 时，一切正常。此外，当使用 Istio 但不包括 Cloud-gateway 时，一切正常。

似乎问题在于 Istio 添加了标头 Content-length=0，而 Cloud-gateway 落在了 websocket 握手上。

我们该如何应对？也许我们需要在 application.yml 中添加一些东西，或者一些 bean 等？
