A simple example of an HTTP upload and download in Go

Hi.
I have the same issue on the Postman. At first, the problem occurred because of uploadFile
key then it has occurred because of the first CANT_WRITE_FILE
statement:
defer newFile.Close()
if _, err := newFile.Write(fileBytes); err != nil || newFile.Close() != nil {
renderError(w, "CANT_WRITE_FILE2", http.StatusInternalServerError)
return
}
Any suggestion?
It's admittedly a common mistake to forget it, File.Close()
can and sometimes does return an error, too, which needs to be handled. (Close()
is idempotent, you can call it multiple times.)
As next step you will need to check if a file has been created (despite the error), and if so then remove it.
(Or more elegantly, create with Linux' O_TMPFILE
. See my caddy.upload.)
In article, it is mentioned that const maxUploadSize = 2 * 1024 // 2 MB
. But actually right value for 2MB is 2 * 1024 * 1024
Also minor typo: there are two variables filetype
and fileType
You know, there are people like me who copy/paste code without reading whole article and directly deploy to prod without testing :)

最近一直在找 https-server
类型的上传下载服务器
最近不是 golang
比较火吗?
所以,有兴趣 再修个轮子吗?
大致流程:
server:监听并运行http服务
