this is my solution of an interview task:
- create a go service that reads from a YAML config file:
apiKeys:
- a
- b
- couldBeOneOrMore
- reallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylongreallylong listenPort: 80 mongoDb: connectionString: “mongodb://localhost:27017” targetCollection: "auditlogs"
-
app shall start an multi-threaded http server on the configured port
-
the server shall accept a REST call (POST to /auditlog) that requires a JSON structure, i.e.:
{
