弹性魔豆CORS的配置POST请求

我提交从我的本地POST请求时收到以下错误 -弹性魔豆CORS的配置POST请求

XMLHttpRequest cannot load http://sample-env.elasticbeanstalk.com/resource 
Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:8080' is therefore not allowed access

但是，在我的S3实例的CORS配置编辑器，我有以下几点 -

<?xml version="1.0" encoding="UTF-8"?> 
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> 
<CORSRule> 
    <AllowedOrigin>*</AllowedOrigin> 
    <AllowedOrigin>http://*</AllowedOrigin> 
    <AllowedOrigin>https://*</AllowedOrigin> 
    <AllowedMethod>GET</AllowedMethod> 
    <AllowedMethod>POST</AllowedMethod> 
    <MaxAgeSeconds>3000</MaxAgeSeconds> 
    <AllowedHeader>*</AllowedHeader> 
</CORSRule>

我已经与这三条线玩耍了，但我仍然无法诊断问题。

<AllowedOrigin>*</AllowedOrigin> 
    <AllowedOrigin>http://*</AllowedOrigin> 
    <AllowedOrigin>https://*</AllowedOrigin>

我的开发者控制台显示如下头，这让我觉得这个CORS配置甚至不被读取 -

HTTP/1.1 200 OK 
Date: Fri, 21 Apr 2017 02:48:01 GMT 
Server: Apache-Coyote/1.1 
Allow: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS 
Content-Length: 0 
Keep-Alive: timeout=60, max=98 
Connection: Keep-Alive 
Content-Type: text/plain

有谁看到什么毛病我的配置还是有别的东西，必须添加？我能够将CORS过滤器添加到我的tomcat的web.xml中，并且一切正常，所以我认为我正确配置了我的弹性beanstalk。

编辑

添加了以下config文件（前身，.yaml）

add_cors.config.config

files: 
"/etc/httpd/conf.d/cors.conf" : 
    mode: "000644" 
    owner: root 
    group: root 
    content: | 
     <Location "/"> 
      Header set Access-Control-Allow-Origin: * 
      Header set Access-Control-Allow-Methods: "POST, GET, PUT, DELETE, OPTIONS" 
      Header add Access-Control-Allow-Headers: "Authorization, Content-Type, Accept" 
      Header set Access-Control-Allow-Credentials: true 

      SetOutputFilter DEFLATE 
     </Location>

它是在爆炸战争这个位置 -

. 
├── app.war 
├── .ebextensions 
│   ├── add_cors.config.yaml 
├── META-INF 
│   ├── … 
└── WEB-INF 
    ├── classes 
    │   └── … 
    ├── servlet.xml 
    ├── lib 
    │   ├── … 
    └── web.xml

我重新部署了这场战争，但我仍然有同样的错误 - “不”Acc ESS-控制允许来源标头是本”

SOLUTION

否.ebextensions文件是必要的。我只是需要在CORS筛选器添加到web.xml就像我在我的tomcat的conf/web.xml中有
