IE11 CORS 拒绝 https 上的选项

Question

IE11 出于某种原因拒绝 PUT 请求，但仅当我使用 https 时。我很难找到问题，因为使用 http、localhost 和其他浏览器工作正常。

控制台显示两个错误

SEC7124: Request method PUT was not present in the Access-Control-Allow-Methods list.
SCRIPT7002: XMLHttpRequest: Network Error 0x80070005, Access is denied.

浏览器发送的OPTION请求是

Accept: */*
Accept-Encoding: gzip, deflate
Access-Control-Request-Headers: accept, content-type, session-id
Access-Control-Request-Method: PUT   
Cache-Control: no-cache 
Connection: Keep-Alive  
Content-Length: 0  
Host: api.domain.com  
Origin: https://portal.domain.com
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko

服务器的响应如下：

X-Powered-By: Servlet/2.5
Server: server
Content-Encoding: gzip
Access-Control-Expose-Headers: Session-Id
Access-Control-Allow-Origin: *
Access-Control-Max-Age: -1
Allow: OPTIONS,GET,HEAD,PUT
Access-Control-Allow-Methods: OPTIONS, GET, POST, PUT, DELETE
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: accept, origin, Content-Type, session-id, authorization, portal-url
Content-Type: application/vnd.sun.wadl+xml
Content-Length: 352

AngularJS 在客户端使用标准 $http PUT。 Java 在服务器端使用球衣，处理 CORS 的请求过滤器如下：

 public ContainerResponse filter( final ContainerRequest request, final ContainerResponse response )
{
    if ( request.getHeaderValue( "Origin" ) != null ) 
    {
        final MultivaluedMap<String, Object> headers = response.getHttpHeaders();
        headers.add( "Access-Control-Allow-Origin", "*" );
        headers.add( "Access-Control-Expose-Headers", "Session-Id" );
        headers.add( "Access-Control-Allow-Credentials", Boolean.TRUE.toString() );
    }

    if ( "OPTIONS".equals( request.getMethod() ) ) 
    {
        final MultivaluedMap<String, Object> headers = response.getHttpHeaders();
        for ( String method : ["OPTIONS", "GET", "POST", "PUT", "DELETE"] ) 
        {
            headers.add( "Access-Control-Allow-Methods", method );
        }
        headers.add( "Access-Control-Allow-Headers",
                "accept, origin, Content-Type, session-id, authorization, portal-url, " 
                + "If-Modified-Since, Cache-Control, Pragma" );
        headers.add( "Access-Control-Max-Age", "-1" );            
    }

    return response;
}

也许你能看出这有什么问题。

谢谢

我已经找到问题了。

我在 https 上看到这个问题只是因为门户和主机在不同的域上。我无法在本地主机上复制该问题，因为服务器和门户都在同一个域中。这意味着 OPTION 请求没有发送，一切都按预期工作。在运行 localhost 上的门户并使用 IP 地址作为服务器 URL 而不是 localhost 之后，OPTION 请求包含在请求中，我可以复制我的问题。

问题本身归结为服务器上的以下代码

    for ( String method : ["OPTIONS", "GET", "POST", "PUT", "DELETE"] ) 
    {
        headers.add( "Access-Control-Allow-Methods", method );
    }

出于某种原因，IE 不喜欢多个 Access-Control-Allow-Methods headers。将代码更改为以下问题后解决了。

 List<String> ALLOWED_METHODS = Arrays.asList( "OPTIONS", "GET", "POST", "PUT", "DELETE" );
 headers.add( "Access-Control-Allow-Methods", ALLOWED_METHODS );
