go后端如何支持HEIC/HEIF图片？
我很新来。我有一些图像上传代码，我正在尝试上传*。HEIC由iPhone产生的图像。我的代码正在执行以下操作：
contentType := http.DetectContentType(fileBytes)
detectContentType不知道如何检测HEIC的内容类型，这导致默认application/optrappy/octet-stream content类型。有没有办法增加对GO的新内容类型的支持？
I am pretty new to Go. I have some image upload code and I am trying to upload a *.heic image that is produced by iPhones. My code is doing the following:
contentType := http.DetectContentType(fileBytes)
DetectContentType does not know how to detect content type for HEIC, which results in default application/octet-stream content type. Is there a way to add support for new content types that Go does not know how to handle yet?

http.detectcontenttype函数旨在匹配媒体类型嗅探规范。因此，这是不可扩展的。但是，您不需要扩展它：没有什么可以阻止您编写自己检测HEIC的功能，并且如果数据与HEIC不匹配，则可以回到
http.detectContentType。The
http.DetectContentTypefunction is designed to match the Media Type Sniffing specification. As such, it's not extensible.However, you don't need to extend it: there's nothing preventing you from writing your own function that detects HEIC, and that falls back to
http.DetectContentTypeif the data does not match HEIC.该库比
http.DetectContentType中的构建具有更广泛的支持：https:// /github.com/gabriel-vasile/mimetype
它会正确识别 HEIC 图像，尽管据我所知，Go 没有对 HEIC 的“原生”支持（有库，但它们只是包装器） C绑定/libde265 等）。
This library has much wider support than the build in
http.DetectContentType:https://github.com/gabriel-vasile/mimetype
It'll correctly recognise HEIC images, although there is no "native" Go support for HEIC that I'm aware of (there are libraries, but they are just wrappers around C bindings/libde265 etc).
