JAX-RS自定义标头未添加到重定向响应中

Question

我正在尝试将一些自定义标头参数添加到HTTP 303（重定向）响应中。但是，新标题似乎从响应中被剥离。

此代码用于接收请求并返回HTTP 303响应：

@POST
@Path("/authorize")
@Produces("application/x-www-form-urlencoded")
public Response getOAuthGrant(@HeaderParam(OAuth2.AUTHORIZATION)    @DefaultValue("") String authorization,
                              @HeaderParam(OAuth2.CLIENT_ID)        @DefaultValue("") String clientId,
                              @HeaderParam(OAuth2.CLIENT_SECRET)    @DefaultValue("") String clientSecret,
                              @HeaderParam(OAuth2.GRANT_TYPE)       @DefaultValue("") String grantType) throws InternalServerException, UnauthorizedException {

        OAuth2.validateGrantRequest(clientId, clientSecret, authorization, grantType);

        ApiTokenV2 apiTokenV2 = new ApiTokenV2();

        try {
            apiTokenV2 = TokenManager.getApiToken(clientId);

            if (apiTokenV2 != null) {
                apiTokenV2.generateAccessGrant(clientId);
            } else {
                logger.error("Error in TokenEndpoint. Retrieved token is null.");
                throw new InternalServerException("A server error occurred while trying to authorize the requester. Could not find 'generateAccessGrant' method");
            } 
        } catch (NamingException e) {
            throw new InternalServerException("A server error occurred while trying to authorize grant request. Could not find 'generateAccessGrant' method.", e);
        }

        return Response.status(Response.Status.SEE_OTHER)
                       .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
                       .header("Location", "/api/token")
                       .header("Authorization", "OAuth")
                       .header("Access-Grant", apiTokenV2.getAccessGrant())
                       .build();
}

我在这里做错了什么？我应该使用@Context吗？
