How do you do File Upload method in AppServices for aspnetboilerplate?

Question

I really like aspnetboilerplate framework, I learning/using it now..

How do you do \'File Upload\' logic/method in AppServices for aspnetboilerplate? The angular par

Answer 1

We implement file upload method : - use sql server fileTable technology - implement application method's service to accept data similar to this Dto

 public FileDto File { get; set; }

...

public class FileDto
{
    public FileDto()
    {

    }
    public FileDto(string file, string fileType)
    {
        File = file;
        FileType = fileType;
    }
    [DisableAuditing]
    public string File { get; set; }
    public string FileName { get; set; }
    public Guid? StreamId { get; set; }
    public string FileType { get; set; } = "";
    [DisableAuditing]
    public string FileWithHeader
    {
        get
        {
            if (FileType == null|| FileType=="")
                return "";
            if (FileType.ToLower() == "jpg" || FileType.ToLower() == "jpeg")
                return "data:image/Jpeg;base64," + File;
            if (FileType.ToLower() == "png")
                return "data:image/png;base64," + File;
            if (FileType.ToLower() == "gif")
                return "data:image/gif;base64," + File;
            if (FileType.ToLower() == "ppt")
                return "data:application/vnd.ms-powerpoint;base64," + File;
            if (FileType.ToLower() == "xls")
                return "data:application/vnd.ms-excel;base64," + File;
            if (FileType.ToLower() == "doc")
                return "data:application/msword;base64," + File;
            if (FileType.ToLower() == "zip")
                return "data:application/zip;base64," + File;
            if (FileType.ToLower() == "exe")
                return "data:application/octet-stream;base64," + File;
            if (FileType.ToLower() == "txt")
                return "data:text/plain;base64," + File;
            if (FileType.ToLower() == "pdf")
                return "data:application/pdf;base64," + File;
            if (FileType.ToLower() == "bmp")
                return "data:image/bmp;base64," + File;
            if (FileType.ToLower() == "csv")
                return "data:text/csv;base64," + File;
            if (FileType.ToLower() == "pptx")
                return "data:application/vnd.openxmlformats-officedocument.presentationml.presentation;base64," + File;
            if (FileType.ToLower() == "xlsx")
                return "data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64," + File;
            if (FileType.ToLower() == "docx")
                return "data:application/vnd.openxmlformats-officedocument.wordprocessingml.document;base64," + File;
            if (FileType.ToLower() == "rar")
                return "data:application/x-rar-compressed;base64," + File;
            if (FileType.ToLower() == "rtf")
                return "data:application/rtf;base64," + File;
            return "";
        }
    }
}

and method implementation

 public UploadFileOutput UploadFile(UploadFileInput input)
    {
        if (input.Id <= 0 || input.File == null)
        {
            throw new UserFriendlyException(L("GetDataError"));
        }

        return new UploadFileOutput()
        {

            StreamId = _attachmentRepo.InsertAttachment(input.File.FileName, Convert.FromBase64String(input.File.File), LIMSConsts.HeightThumbnail, true, ServerConfig.ThumbnailImagePath),
        };

    }

insertAttachment method:

public Guid InsertAttachment(string fileName, byte[] fileStream, int heightThumbnail = 50, bool saveThumbnail = false,string thumbLocationPath=null)
    {

        Guid AttachmentId = Guid.Empty;

        SqlParameter _attachmentId = new SqlParameter();
        _attachmentId.ParameterName = "@attachmentId";
        _attachmentId.Direction = System.Data.ParameterDirection.InputOutput;
        _attachmentId.Value = AttachmentId;

        SqlParameter _fileStream = new SqlParameter();
        _fileStream.SqlDbType = System.Data.SqlDbType.VarBinary;
        _fileStream.Value = fileStream;
        _fileStream.ParameterName = "@fileStream";

        Context.Database.ExecuteSqlCommand("EXECUTE dbo.sp_AttachmentFile_Insert @AttachmentId OUTPUT,@fileName,@fileStream",
            _attachmentId,
            new SqlParameter("@fileName", fileName),
            _fileStream);

        if (saveThumbnail == true) {
            var ms = new MemoryStream(fileStream);
            var image = Image.FromStream(ms);

            var width = (int)(heightThumbnail * image.Width / image.Height);
            var height = (int)(heightThumbnail);

            var Thumbnail = new Bitmap(width, height);
            Graphics.FromImage(Thumbnail).DrawImage(image, 0, 0, width, height);                
            Bitmap Thumb= new Bitmap(Thumbnail);
            Thumb.Save(Path.Combine(thumbLocationPath, _attachmentId.Value+".jpg"), ImageFormat.Jpeg);

        }

        return (Guid)_attachmentId.Value;
    }

and Stored procedure implementation

ALTER PROC [dbo].[sp_AttachmentFile_Insert]
@AttachmentId uniqueidentifier out,
@fileName nvarchar(256),
@fileStream VARBINARY(max)

AS SET @AttachmentId=NEWID()

WHILE(EXISTS(SELECT 1 FROM dbo.Attachment WHERE name=@fileName))
BEGIN
    DECLARE @fileExtention NVARCHAR(100)
    SELECT @fileExtention ='.'+dbo.GetFileExtension(@fileName)
    SET @fileName=REPLACE(@fileName,@fileExtention,'')+
        CAST(DATEPART( DAY, GETDATE()) AS VARCHAR(10))+'_'
        +CAST(DATEPART( HOUR, GETDATE()) AS VARCHAR(10))+'_'+
        +CAST(DATEPART( MINUTE, GETDATE()) AS VARCHAR(10))+'_'+
        +CAST(DATEPART( SECOND, GETDATE()) AS VARCHAR(10))+@fileExtention
END

INSERT into dbo.Attachment(stream_id,name,file_stream)
    VALUES(@AttachmentId,@fileName,@fileStream)

and finally Thank to "Halil İbrahim Kalkan" for thihs awesome framework.
