我一直在尝试使用elasticsearch.jquery.min.js ping 本地运行的elasticsearch,但每次都会收到“无事件连接”错误。
<小时/>预计到达时间:在 Chrome 中,我看到了一个看起来相当低级别的“连接被拒绝”。我正在 MacOS X 上进行开发,我的浏览器通过 http://localhost/~myuserid/SiteName/
指向该页面。当我访问 localhost:9200 时,这显然属于跨域 CORS 要求。
我在 Chrome 控制台中看到以下错误:
XMLHttpRequest cannot load http://localhost:9200/?hello=elasticsearch!.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://localhost' is therefore not allowed access.
每http://enable-cors.org/server_apache.html我已将以下内容添加到/etc/apache2/httpd.conf:
<Directory />
Header set Access-Control-Allow-Origin "localhost:9200"
AllowOverride none
Require all denied
</Directory>
然后运行
$ sudo apachectl -t
$ sudo apachectl -k graceful
但错误仍然存在。还有其他我忽略的设置吗?
<小时/>我是elasticsearch.js 的菜鸟。我需要在elasticsearch方面做些什么来允许来自浏览器的客户端连接或者其他什么吗?
我正在关注the book在我的 ping 尝试中:
var client = new $.es.Client({
hosts: 'localhost:9200'
});
client.ping(
{
requestTimeout: Infinity,
// undocumented params are appended to the query string
hello: "elasticsearch!"
},
function (error) {
if (error) {
console.error('elasticsearch cluster is down!');
console.error(error);
} else {
console.log('All is well');
}
}
);
但我收到以下错误:
"WARNING: 2015-10-10T07:00:16Z" elasticsearch.jquery.min.js:14:10575
Unable to revive connection: http://localhost:9200/
"WARNING: 2015-10-10T07:00:16Z" elasticsearch.jquery.min.js:14:10575
No living connections
我可以在命令行上使用curl进行连接,拉取和插入数据等:
$ curl "localhost:9200/_cat/indices?v"
health status index pri rep docs.count docs.deleted store.size pri.store.size
green open fuddle 1 0 3 0 12.9kb 12.9kb
green open faddle 1 0 0 0 144b 144b
预计到达时间附加诊断。 Google Chrome 显示失败尝试的以下网络跟踪。在 HTTP 层,响应看起来像是正在发生。

我真的不知道从这里该去哪里。我在 googlz 上看到很多对该错误的引用,但没有一个情况看起来完全相似。感觉就像我遇到了一些配置错误,但我找不到任何可以表明那是什么的东西。
最佳答案
好吧,那是一个艰难的过程。
解决方法如下:
每http://enable-cors.org/server_apache.html ,在/etc/apache2/httpd.conf
中,配置Access-Control-Allow-Origin:
<Directory />
# Add the following line to enable CORS to connect to local elasticsearch.
Header set Access-Control-Allow-Origin "localhost:9200"
AllowOverride none
Require all denied
</Directory>
每https://jsbroadcast.com/elastic-search-cors/ ,在elasticsearch-1.7.0/config/elasticsearch.yml
中添加:
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"
我现在可以运行 client.ping
调用,不会出现任何错误。
