check return value of `File.Close()`

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.)

Fix maxUploadSize in article

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 :)

我在使用postman上传文件的时候，为什么会报错

file, _, err := r.FormFile("uploadFile")
在这一句中，err爆出异常http: no such file
然后我回头输出了一下r.Body的大小,发现是0
请问这是怎么回事呢

这是我postman的参数

some typo error in uploadFileHandler()

it should be like pic below.

Get CANT_WRITE_FILE error when I upload a file using Postman

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?

Typo 2014 -> 1024

const maxUploadSize = 2 * 1024 * 2014 // 2 mb

Hello

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

• Markdown：自动修改文件名 把特殊字符修改为下划线
• Markdown 自动填充字段，首尾填充
• 图片：接收图片并按照时间戳重命名，返回JSON数据

clinet：

• 向server 发送图片和 markdown文件
• 接收JSON数据并转达 应用

当然有推荐的欢迎指出，谢谢，❤️
