Kibana Canvas 插件不适用于 SearchGuard

Question

我已经安装了 6.3.0 版的 ELK 堆栈，并且还在 Kibana 中安装了 Canvas 插件。 但它似乎不起作用，因为 Canvas 创建对 Elasticsearch 的请求时存在身份验证问题。 我使用 SearchGuard 进行身份验证而不是 X-Pack 安全性。

下面是我的安装细节：

1. Elasticsearch
    Version: 6.3.0
    Plugins: - search-guard-6

2. Kibana
    Version: 6.3.0
    Plugins: - canvas@0.1.2015
             - searchguard@6.3.0-13

这是 kibana 日志输出：

我该如何解决这个问题？ 有什么建议？

Answer 1

最后，我自己找到了这个问题的临时解决方案。

我正在编辑第 37 行中的文件/plugins/canvas/server/routes/socket.js ：

if (server.plugins.security) request.headers.authorization = authHeader;

到：

request.headers.authorization = "Basic <HASHED_USER_PASS>";

是SearchGuard 用户名：用 Base64 编码的SearchGuard 密码。

我知道我的解决方案可能不是最好的解决方案，需要改进，但我希望它可以帮助遇到相同问题的其他用户。

谢谢。
