Description
使用的antd版本是3.19.5，上传的方法是服务器端签名，js直传
我可以确定的是oss是配置了允许跨域的，小程序可以通过我服务器段生成的签名，policy上传文件
oss提供的jssdk也是可以的，但是用antd的上传组件不行，一直提示跨域
Access to XMLHttpRequest at 'https://xxx.com/' from origin 'https://xxxxxx.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
具体代码如下

Research direction
Start by reproducing the antd 3.19.5 upload flow using server-side signing and direct OSS upload. Inspect the upload component's request and preflight behavior against the reported CORS error, then compare it with the working OSS JavaScript SDK flow. Done means the signed upload completes without the browser blocking the preflight request.
