如何配置 Knox 使其将授权 header 传递给后端服务？

Question

正如我在问题中所讨论的那样，Knox 不支持 websockets 身份验证，但作为临时解决方案，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 没有将授权 header 传递给后端。

[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）以使其通过授权 header 到后端以进行 websocket 连接？

Answer 1

在写这个问题时，我意识到有一张票 KNOX-895 解决了将 cookie 和 headers 传递到 Knox 0.14.0 后端服务的问题。

[编辑]

我克隆了 knox git 存储库（提交 92b1505a），其中包括 KNOX-895 (2d236e78)，运行它在本地添加了 websocket 服务到沙箱拓扑。

[tulinski]$ wscat -n --auth 'user:password' -c wss://localhost:8443/gateway/sandbox/echows
[tulinski]$ sudo ngrep -W byline host echo.websocket.org
#
T 192.168.0.16:59952 -> 174.129.224.73:80 [AP]

授权header 已传递到后端服务。
