彈性魔豆CORS的配置POST請求

我提交從我的本地POST請求時收到以下錯誤 -彈性魔豆CORS的配置POST請求

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實例的CORS配置編輯器，我有以下幾點 -

<?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>

我已經與這三條線玩耍了，但我仍然無法診斷問題。

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

我的開發者控制檯顯示如下頭，這讓我覺得這個CORS配置甚至不被讀取 -

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

有誰看到什麼毛病我的配置還是有別的東西，必須添加？我能夠將CORS過濾器添加到我的tomcat的web.xml中，並且一切正常，所以我認爲我正確配置了我的彈性beanstalk。

編輯

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>

它是在爆炸戰爭這個位置 -

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

我重新部署了這場戰爭，但我仍然有同樣的錯誤 - 「不」Acc ESS-控制允許來源標頭是本」

SOLUTION

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