elasticsearch.js客户端连接被拒绝：访问控制允许来源不承认？ [英] elasticsearch.js client connection refused: Access-Control-Allow-Origin not recognized?
问题描述
我一直在尝试使用elasticsearch.jquery.min.js ping一个本地运行elasticsearch每次我得到一个没有生活连接的错误。
I've been trying to ping a locally running elasticsearch using elasticsearch.jquery.min.js and I get a "no living connection" error each time.
ETA：在Chrome中我看到什么样子了pretty低水平拒绝连接。我开发在MacOS X和我的浏览器，透过 HTTP页面指向：//本地主机/〜myuserid /网站名称/ 。当我访问本地主机：9200 这下跨域CORS要求显然属于
ETA: In Chrome I see what looks like a pretty low level "Connection Refused". I'm developing on MacOS X, and my browser points at the page via http://localhost/~myuserid/SiteName/. As I'm accessing localhost:9200 this clearly falls under cross domain CORS requirements.
我看到下面的错误在Chrome控制台：
I see the following error in the Chrome console:
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.
Per http://enable-cors.org/server_apache.html I've added the following to /etc/apache2/httpd.conf:
<Directory />
Header set Access-Control-Allow-Origin "localhost:9200"
AllowOverride none
Require all denied
</Directory>
和运行
$ sudo apachectl -t
$ sudo apachectl -k graceful
但错误依然存在。有我俯瞰另一个设置？
but the error persists. Is there another setting I'm overlooking?
我对elasticsearch.js一个小白。有什么我需要做的elasticsearch方允许从浏览器，或一些客户端连接？
I'm a noob to elasticsearch.js. Is there anything I need to do on the elasticsearch side to allow client connections from the browser, or something?
我在下面的书在我的ping尝试：
I'm following the book in my ping attempt:
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');
}
}
);
但我发现了以下错误（S）：
but I'm getting the following error(s):
"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
我可以连接使用命令行就好上的卷曲，拉和插入数据等。
I can connect using curl on the command line just fine, pull and insert data, etc.:
$ 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
ETA附加诊断。谷歌浏览器显示了失败的尝试以下网络痕迹。在HTTP层的响应看起来像它的发生。
ETA additional diagnostics. Google Chrome shows the following network traces for the failing attempt. At the HTTP layer the response looks like it's happening.

我真的很茫然哪里何去何从。我看到很多引用对德googlz错误，但没有的情况下，似乎远程相似。这感觉就像我只是打了一些错误配置，但我找不到任何可以表明那是什么。
I'm really at a loss where to go from here. I see lots of references to the error on teh googlz, but none of the circumstances seem remotely similar. It feels like I'm just hitting some misconfiguration, but I can't find anything that would indicate what that is.
推荐答案
嗯，这是一个艰难的一个。
Well, that was a tough one.
下面就是固定它：
/等/ apache2的/ httpd.conf文件，配置访问控制允许来源：
Per http://enable-cors.org/server_apache.html, in /etc/apache2/httpd.conf, configure 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<一个href=\"https://jsbroadcast.com/elastic-search-cors/\">https://jsbroadcast.com/elastic-search-cors/,在 elasticsearch-1.7.0 /配置/ elasticsearch.yml 补充：
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"
我现在可以运行没有任何错误的 client.ping 电话。
