[FEATURE REQUEST] Can the upload support front-end direct transmission?

[7FreezingPoint]

Why this feature?

目前上传不管是到minio、oss、cos等渠道，都需要经过服务端

Suggested Solution

希望服务端适配存储厂商签名方案，返回前端签名由前端直接调用存储厂商完成上传，节省服务端带宽

目前应该支持此功能，你可以通过业务代码上传后再将文件地址通过openIM发送即可，参考链接： https://docs.openim.io/zh-Hans/sdks/api/message/createFileMessageByURL https://docs.openim.io/zh-Hans/sdks/api/message/createImageMessageByURL https://docs.openim.io/zh-Hans/sdks/api/message/sendMessageNotOss

This function should be supported at present. You can upload it through the business code and then send the file address through openIM.

File browsing does not go through the server, directly connect to s3
