Question

我正在开发一个软件项目，并且正在使用Elasticsearch支持我的搜索功能。我有一台用于测试的服务器，并且正在使用docker compose创建集群。每当我使用我的应用搜索栏（通过与ES在同一服务器上的Apache托管）时，由于CORS的限制，我永远都无法获得响应（我正在使用Chrome扩展程序来解决此问题，但是我不希望用户拥有安装此文件进行搜索）。

我尝试在elasticsearch.yml文件中启用适当的http设置，但是似乎没有做任何事情。我正在使用Elasticsearch javascript模块发出请求。

docker-compose：

elasticsearch.yml：

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-methods: OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers: "X-Requested-With,X-Auth-Token,Content-Type, Content-Length, Authorization"

我如何连接到ES（使用javascript）：

var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
  host: 'myServersIP:9200'
});

因此，当我访问服务器网页（www.mydomain.com）时，我得到了应用程序，一切看起来都不错。尝试搜索时，出现COR问题，无法返回任何结果。我认为这可能是因为我通过“ myServersIP：9200”而不是某些代理子域连接到客户端，但是我不确定。关于我可能做错了什么/如何解决此问题的任何想法？

Answer 1

尝试在C：\ ProgramData \ Elastic \ Elasticsearch \ config（Windows案例）下进行操作

编辑它并（负责任地）添加CORS配置，因为“ *”非常危险

希望这对您有帮助
