Simple golang sudoku solution verifier. This is by no means a robust and optimal system, but that's not the point -- it just needs to work for verifying the solution to the sudoku.
What's a sudoku? Allow Wikipedia to tell you: Sudoku
It listens on the port 4590 for incoming HTTP POST
operations to the /verify endpoint. This is the only implemented endpoint and the only valid verb.
The endpoint will return HTTP 400 if anything is wrong
with the provided data (including if the body is missing). It will return HTTP 200 if it is capable of parsing and understanding the data; if it is a valid Sudoku solution then a body of 1 is sent back; otherwise 0 is returned.
The implementation has a 50 ms delay built into it to simulate sending data over the actual internet. It is likely that for the assignment all the servers and clients will be in the same network (or at least geographically nearby) and the delay makes the test scenario a bit more plausible.
This requires golang to be installed. Use go build to compile; go run to execute. It is suggested to run this in a screen session so it remains resident and so the output doesn't spam your console.
There are a few simple test files provided in the testfiles directory. You can test at the commandline with the curl utility using:
curl -X POST -H "Content-Type: application/json" --data '@filename' -v server:4590/verify
Just replace the filename with the one you want and the server with the correct servername (e.g., localhost).
