XMLHttpRequest无法加载http：// localhost：9200 /。 elasticsearch

Question

我在我的Windows机器上运行弹性搜索，我可以curl -XGET "http://localhost:9200/movies/_search"并获得一大堆对象。

当我尝试用角度请求var client = elasticsearch({ host: 'localhost:9200' });时，我会得到以下内容。

XMLHttpRequest cannot load http://localhost:9200/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access.

我在elasticsearch.yml内添加了

http.cors.allow-origin: "*"
http.cors.enabled: true

并尝试

http.cors.allow-origin: "/localhost(:[0-9]+)?/"
