http2ftp is an experimental bridge between the FTP and the HTTP protocol. It provides the necessary means to easily create an FTP frontend for a webapplication, to allow easy import/export of data for customers, which need FTP interfaces (ERP-Systems anyone? ;).

The bridge is considered highly experimental. Even though I am loosely planning on using it for a project myself in the future, I created it as means to learn and play around with Go. The first version of this endeavor has been created with 1 1/2 days of Go knowledge. Therefore be warned it might not be production ready ;).

After installing Go simply issue the following command to install the project into your $GOPATH/bin folder:

$ go get github.com/jakobwesthoff/http2ftp/cmd/http2ftp

The http2ftp executable should be ready for usage after that. Execute it with the -h flag to retrieve more information about configuration options.

The bridge is configured using a bunch of JSON files. Each user account has its own .json file within the configuration folder. The filename reflects the username. To allow a user called jakob to login to the FTP bridge a file named jakob.json needs to be created inside the configuration directory. The path of the directory itself may be specified using the --config flag.

The configuration file hosts the password for the user account, as well the directory and file structure displayed once the user is logged in. Each file or directory may specify so called endpoints, which reflect their mapping to a HTTP resource. Endpoints may be read and write endpoints allowing to specify what should happen once a user reads the resource or writes to it. Directories might either contain other directory and file definitions directly within the configuration or provide a read endpoint, which is queried once the directory is listed. This endpoint has to return the exact same JSON structure, which is used to configure directory entities within the static configuration.

An example configuration, which demonstrates the different structural possibilities can be found under config/jakob.json within the repository.
