How to support HEIC/HEIF images in go backend?
问题
我对Go还不太熟悉。我有一些图片上传的代码，我想要上传由iPhone生成的*.heic格式的图片。我的代码正在执行以下操作：
contentType := http.DetectContentType(fileBytes)
DetectContentType方法无法识别HEIC的内容类型，导致默认的内容类型为application/octet-stream。有没有办法为Go添加对尚未支持的新内容类型的支持呢？
英文:
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?

得分: 1
http.DetectContentType函数旨在匹配媒体类型嗅探规范。因此，它不可扩展。
然而，你不需要扩展它：你可以编写自己的函数来检测HEIC，并在数据不匹配HEIC时回退到http.DetectContentType。
英文:
The http.DetectContentType function 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.DetectContentType if the data does not match HEIC.
