我正在通过 AJAX 上传文件。但是，我收到此错误:
Request header field token is not allowed by Access-Control-Allow-Headers
这是我上传到的网站的响应 header ，响应 header 看起来都很好:
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
Access-Control-Max-Age: 1728000
Cache-Control: no-cache

这是请求 header :
OPTIONS /v1_1/*****/image/upload HTTP/1.1

Cache-Control: no-cache
Pragma: no-cache
Access-Control-Request-Method: POST

Accept: */*
Referer: http://admin.lvho.st:9292/venue/
Accept-Encoding: gzip,deflate,sdch

响应 header 中是否有遗漏/错误的内容？
谢谢
最佳答案
预检 (OPTIONS) 响应中的 Access-Control-Allow-Headers header 缺少对“ token ” header 的引用。您将需要更新您的服务器响应以说明此 header 。
