Kibana Canvas 插件不适用于 SearchGuard答案

【问题标题】：Kibana Canvas plugin doesn't works with SearchGuardKibana Canvas 插件不适用于 SearchGuard
【发布时间】：2018-12-13 11:15:22
【问题描述】：

我已经安装了版本为 6.3.0 的 ELK 堆栈，并且我还在 Kibana 中安装了 Canvas 插件。但它似乎不起作用，因为当 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

这里是 kibana 日志输出：

我该如何解决这个问题？有什么建议吗？

谢谢

【解决方案1】：

最后，我自己找到了这个问题的临时解决方案。

我正在编辑文件 /plugins/canvas/server/routes/socket.js 在第 37 行：

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

到：

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

SearchGuard 用户名：SearchGuard 密码 使用 Base64 编码。

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其他用户解决同样的问题。

谢谢。
