jquery 'Request header field token is not allowed by Access-Control-Allow-Headers'

Question

我正在通过AJAX上传文件。但是，我遇到了这个错误：

Request header field token is not allowed by Access-Control-Allow-Headers

这是我要上传到网站的响应标题，响应标题似乎都很好：

HTTP/1.1 200 OK
Access-Control-Allow-Headers: X-Requested-With, X-Prototype-Version, Content-Disposition, Cache-Control, Content-Type
Access-Control-Allow-Methods: POST, GET, OPTIONS
Access-Control-Allow-Origin: http://admin.lvho.st:9292

这是请求标题：

响应标题中是否有些缺少/错误？

谢谢

在响应前（选项）中，访问控制的标题（选项）缺少对"令牌"标头的引用。您将需要更新服务器响应以考虑此标题。
