elasticsearch.js客户端连接被拒绝：访问控制允许来源不承认？

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.

http://enable-cors.org/server_apache.html 我添加以下为/etc/apache2/httpd.conf：

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

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.

在wget的同一请求：

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：

，http://enable-cors.org/server_apache.html 在 /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。
