[cli] Add a tail command to follow server logs #85
Description
Could be helpful to have a way to display HTTP requests info.
In the CLI program we could add a command line parameter to the server command, say --tail which would display the HTTP requests being handled by the server.
In the core package, we currently do not have a log middleware. We'd need one and use the logger to ourput nice output, but only if we used the --tail option.
This means that in the config we would need to add a new option to indicate if we want to display the server log or not.
The log middleware would be added to all middleware chains only if that config flag is true.
What I mean by middleware chains can be found in server.go:117:
stdAuth := []middleware.Middleware{
middleware.Cors(),
middleware.WithDB(backend.DB, backend.Cache, getStripePortalURL),
.// ...
}Since they are this function receive the config, the log middleware could accept a flag to be verbose or not, ex:
stdAuth := []middleware.Middleware{
middleware.Log(config.TailRequests),
middleware.Cors(),
middleware.WithDB(backend.DB, backend.Cache, getStripePortalURL),
// ...
}Assuming the config flag would be called TailRequests and the log middleware Log.
If TailRequests is false the middleware simply do nothing.
