File upload server

This is a simple file upload server, intended to enable uploading of many files in parallel.

Prerequisites

• go 1.21.0

Run

The server can be started with go run file-upload-server.go. It will start listening to HTTP POST requests on port 8080.

Use

To upload a file under a randomly generated file name, you can use the the following command: curl -X POST --data-binary @/path/to/file http://localhost:8080

This will create a new directory in the base directory (./uploads/ per default) with a random name. This directory will contain a file called data holding the uploaded data, and data.md5 containing the MD5 sum of the uploaded data:

upload
└── mpkdgxrezjugpaxk
    ├── data
    └── data.md5

Explicitly naming uploads

If you want to force a specific name for the upload, you can use: curl -X POST --data-binary @/path/to/file http://localhost:8080/my-name

This will create the following structure:

upload
└── my-name
    ├── data
    └── data.md5

Rate limiting

Note: curl supports a --rate-limit flag that can be used to limit the transmission speed. This can be useful if you want to see the server's behavior with several parallel uploads.
