#prntserve

Store and serve your funny pictures a.k.a. screenshots.

#Abstract

prntserve is a web application that statically serves files. These files can either be added via the underlying file system or by using a HTTP PUT request on the path where the file should be displayed.

The main use-case for this application is a personal screenshot-sharing service. Though as any filetype can be shared via this method, it can also be used for other applications.

#API

prntserve uses a very simple RESTful API.

#Viewing files

GET /<filename> or HEAD /<filename>

Parameters:

• filename: name of the file (generally the path to the file, relative to document root)

Headers: None

Response:

• 200 OK: File exists
• 307 Temporary Redirect: Effective filename is different from request (e.g. /hello/../1.png redirects to /1.png)
• 404 Not Found: File does not exist

Example:

$ curl -L https://prntserve.example/hello_world.png

#Uploading files

PUT /<filename>

Parameters:

• filename: name of the file (generally the path to the file, relative to document root)

Headers:

• Authorization: Bearer <token>: token or password, which was defined as server parameter

Response:

• 200 OK: File uploaded
• 307 Temporary Redirect: Effective filename is different from request (e.g. /hello/../1.png redirects to /1.png)
• 401 Unauthorized: no/incorrect token
• 409 Conflict: Target filename is in use

Example:

$ curl -LT ~/screenshot.png -H "Authorization: Bearer <token>" https://prntserve.example/unixporn/epic_screenshot.png

#Deleting files

DELETE /<filename>

Parameters:

• filename: name of the file (generally the path to the file, relative to document root)

Headers:

• Authorization: Bearer <token>: token or password, which was defined as server parameter

Response:

• 200 OK: File/Directory deleted
• 307 Temporary Redirect: Effective filename is different from request (e.g. /hello/../1.png redirects to /1.png)
• 401 Unauthorized: no/incorrect token
• 403 Forbidden: Target filename can not ne deleted
• 409 Conflict: Target filename is neither a file nor a directory

Quirks

• Directories need to be empty to be deleted

Example:

$ curl -LX DELETE -H "Authorization: Bearer <token>" https://prntserve.example/unixporn/epic_screenshot.png

#Clients

Currently the only known client for prntserve is screenshot-bash, which is a very un-sophisticated, but extensible, series of scripts to create a screenshot-upload pipeline.
