跨域请求用CORS头$​​ P $ psent阻止 [英] Cross-Origin Request Blocked with CORS headers present

问题描述

在服务器端我有阿帕奇以下过滤器允许所有的方法，并默认所有的来历

on the server side I have the following filter in apache which allow all methods and all origins by defaults

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

采用了棱角分明的$ HTTP一个员额的工作，但另一个失败失败。失败在同一个Apache会谈到另一个应用程序的请求。

Using angular $http One post is working, but another fail failed. The request that fails talks to another app on the same apache.

Cross-Origin Request Blocked: The Same Origin Policy disallows 
reading the remote resource at http://localhost:.. 
(Reason: CORS header 'Access-Control-Allow-Origin' 
does not match 'http://localhost:8100, http://localhost:8100').

但响应头确实包含了ACAO

But the response header does contain the ACAO

HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
access-control-allow-credentials: true, true
access-control-allow-origin: http://localhost:8100, http://localhost:8100
Vary: Origin
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked

在哪里做了的http：//本地主机：8100 ，的 HTTP：//本地主机：8100 从何而来？你是否认为这是角$ HTTP或Apache的问题？

Where did the ' http://localhost:8100, http://localhost:8100' come from ? Do you think it is angular $http or Apache problem ?

推荐答案

访问控制允许来源可以接受'*'或单的为它的价值原点。你不能把一个逗号分隔的列表那里。

Access-Control-Allow-Origin accepts either '*' or a single origin for its value. You can't put a comma-separated list there.

浏览器是匹配的原点（的http：//本地主机：8100 对的http：//本地主机：8100，HTTP：//本地主机：8100 并没有得到匹配

The browser is matching the origin (http://localhost:8100 against http://localhost:8100, http://localhost:8100 and not getting a match.

您之前已经上线了类似的问题。它看起来像您运行的是code插入您的CORS头两次。

You have a similar problem on the line before. It looks like you are running the code to insert your CORS headers twice.
