Upload files

Single file

const maxSize = 8 * iris.MB
func main() {
    app := iris.Default()
    app.Post("/upload", func(ctx iris.Context) {
        // Set a lower memory limit for multipart forms (default is 32 MiB)
        ctx.SetMaxRequestBodySize(maxSize)
        // OR
        // app.Use(iris.LimitRequestBodySize(maxSize))
        // OR
        // OR iris.WithPostMaxMemory(maxSize)
        // single file
        file, fileHeader, err:= ctx.FormFile("file")
        if err != nil {
            ctx.StopWithError(iris.StatusBadRequest, err)
            return
        }
        // Upload the file to specific destination.
        dest := filepath.Join("./uploads", fileHeader.Filename)
        ctx.SaveFormFile(file, dest)
        ctx.Writef("File: %s uploaded!", fileHeader.Filename)
    })
    app.Listen(":8080")
}

Multiple files

See the detail example code.

func main() {
    app := iris.Default()
    app.Post("/upload", func(ctx iris.Context) {
        files, n, err := ctx.UploadFormFiles("./uploads")
        if err != nil {
            ctx.StopWithStatus(iris.StatusInternalServerError)
            return
        }
        ctx.Writef("%d files of %d total size uploaded!", len(files), n))
    })
    app.Listen(":8080", iris.WithPostMaxMemory(8 * iris.MB))
}

How to curl:

curl -X POST http://localhost:8080/upload \
  -F "upload[]=@/Users/kataras/test1.zip" \
