我已将我的 elasticsearch 服务器放在提供基本身份验证的 Apache 反向代理后面。
直接从浏览器向 Apache 进行身份验证工作正常。但是,当我使用 Kibana 3 访问服务器时,我收到身份验证错误。
显然是因为没有身份验证标头与 Kibana 的 Ajax 调用一起发送。
我在 Kibana 供应商目录中的 elastic-angular-client.js 中添加了以下内容,以实现快速而肮脏的身份验证。但由于某种原因,它不起作用。
$http.defaults.headers.common.Authorization = 'Basic ' + Base64Encode('user:Password');
在 Kibana 中实施基本身份验证的最佳方法和位置是什么?

更新 1:我实施了 Matts 的建议。但是,服务器返回一个奇怪的响应。似乎授权标头不起作用。这可能与我在端口 81 上运行 Kibana 而在 8181 上运行弹性搜索这一事实有关吗?

更新 2:在这些 Kibana 文件中使用修改后的标头更新了所有实例
root@localhost:/var/www/kibana# grep -r 'ejsResource(' .
./src/app/controllers/dash.js: $scope.ejs = ejsResource({server: config.elasticsearch, headers: {'Access-Control-Request-Headers': 'Accept, Origin, Authorization', 'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXX=='}});
./src/app/services/querySrv.js: var ejs = ejsResource({server: config.elasticsearch, headers: {'Access-Control-Request-Headers': 'Accept, Origin, Authorization', 'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXX=='}});
./src/app/services/filterSrv.js: var ejs = ejsResource({server: config.elasticsearch, headers: {'Access-Control-Request-Headers': 'Accept, Origin, Authorization', 'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXX=='}});
./src/app/services/dashboard.js: var ejs = ejsResource({server: config.elasticsearch, headers: {'Access-Control-Request-Headers': 'Accept, Origin, Authorization', 'Authorization': 'Basic XXXXXXXXXXXXXXXXXXXXXXXXXXXXX=='}});
并像这样为反向代理修改了我的 vhost conf
<VirtualHost *:8181>

Apache 发回新的响应标头,但请求标头在某处似乎仍然是错误的。身份验证不起作用。

解决方案: 在做了更多研究之后,我发现这绝对是关于 CORS 的配置问题。有很多关于该主题的帖子,但似乎为了解决我的问题,有必要在 apache 上进行一些非常精细的配置,并确保从浏览器发送正确的内容。
所以我重新考虑了策略并找到了一个更简单的解决方案。只需修改 vhost 反向代理配置以将 elastisearch 服务器和 kibana 移动到同一 http 端口上。这也为 Kibana 增加了更好的安全性。
这就是我所做的:
<VirtualHost *:8181>
ProxyRequests Off
ProxyPass /bigdatadesk/ http://127.0.0.1:81/bigdatadesk/src/
ProxyPassReverse /bigdatadesk/ http://127.0.0.1:81/bigdatadesk/src/
