Sample application for chunked file upload

An example to demonstrate chunked file uploading to a .NET Core WebApi 2 server. The client uses Resumable.js, which in turn uses HTML 5 file API to generate the chunks.

A Java version is also available https://github.com/edsoncunha/chunked-file-upload-sample.

How to run

Install requirements:

.Net Core

Run:

cd ChunkedUploadWebApi
dotnet run

Then browse to localhost:5000. API Documentation will be available on localhost:5000/api-docs.

Testing

Generate a large file with random data and compare its checksum with downloaded file's checksum.

Windows:

Create a 1GB dummy file

fsutil file createnew file.tmp 1073741824

Upload generated file.tmp, download it from server and check whether the checksums match with File Checksum Integrity Verifier Utility:

fciv -add file.tmp -sha1

Linux:

Create a 1GB file from /dev/urandom

dd if=/dev/urandom of=file.tmp bs=1M count=1024 #creates a 1GB file

Upload generated files, download it from server and check whether the checksums match with sha1sum

sha1sum file.tmp
