正如我在另一个问题中所讨论的那样，Knox 中不支持 websockets 身份验证，但作为一种临时解决方案，我们可以在后端服务中处理身份验证。然而，我们的测试表明 Knox 没有将 Authorization 标头传递到后端。

[client]$ curl -i -u '<user>:<password>' https://knox-server/gateway/default/myservice/ping

# 8090 is our backend port
[knox-server]$ ngrep -W byline port 8090
interface: eth0
filter: ( port 8090 ) and ((ip || ip6) || (vlan && (ip || ip6)))

#

我应该如何配置 Knox（来自 HDP 2.6.2 的 0.12.0）以使其将 Authorization 标头传递到后端以进行 websocket 连接？

在写这个问题时，我意识到有一张票KNOX-895解决了在 Knox 0.14.0 中将 cookie 和标头传递给后端服务的问题。

我克隆了 knox git repo (commit 92b1505a)，其中包括 KNOX-895 (2d236e78)，在本地运行它，并在沙盒拓扑中添加了 websocket 服务。

[tulinski]$ wscat -n --auth 'user:password' -c wss://localhost:8443/gateway/sandbox/echows
[tulinski]$ sudo ngrep -W byline host echo.websocket.org
#

授权标头被传递给后端服务。
