Simple Wolfram Language Server

This server is written by almost pure Wolfram Language for heuristic purposes.

This server is inspired by wolfram-server but attempts to give a more complicated application of built-in functions for web development.

I may update this code in the future. And you can feel free to submit PRs if you created some applications which meet common requirements.

Usage of files and functions

StartServer.wls

Start a SocketListener with user-defined configuration. Print some useful message.

WolframServer.wl

• HTTPRespond: Process socket data, print a log string and then close client SocketObject. The default response is decided by WolframServerService`$MainURLDispatcher.

WolframServerService.wl

• $MainURLDispatcher: The default URLs dispatcher which dispatch URL to $IndexService, $ServiceDispatcher (Web Service), $APIDispatcher (JSON Response), a GetResource function which meets requirements for files and a dispatcher in WolframServerUserService.wl.

WolframServerTool.wl

• ToMIME: Convert file format postfixes to MIME type strings. It works for WolframServerService`GetResource to provide HTTPResponse[<|"ContentType" -> "MIMEType"|>]. Not finished yet.
• ResourceLocalize: Replace the resources link to wolframcloud.com by local link. It works for WolframServerService`GetResource.
• ApacheLog: Give an Apache-style log. Not a complete function yet.
• MakeFormRules: Convert body bytes in the HTTPRequest received to an association. It works for FormFunction which requires HTTPRequestData["FormRules"].

WolframServerManageTool.wl

• ServerShutdown
• ServerStart
• ServerMonitor: Hold the main loop to forbid process to exit. It works for StartServer.wls in the command line environment.
• ShowLog: Import the log file in the server directory as a string. The default log file is "nohup.out".

WolframServerUserService.wl

There is a simple note service implemented, which is a string list that can be operated by the web UI provided by some FormFunctions.

TestClient.wls

Send a request to the root path of local host on port 8080.

CopyResource.wls

Copy cloud resources to be localized from Wolfram Engine's installation directory. It works for WolframServerTool`ResourceLocalize.

Note

• To provide services to users as a server, you need a proper license.
• There's no security features implemented in WolframServerService`EvaluationService. Users can evaluate anything. Possible expressions includes RunProcess, Quit etc..
