As of Go 1.16, functionality provided in io/ioutil has been depreciated
in favour of the io or os packages. Now that Go has been
upgraded in go.mod, the linter will not pass without these changes.
We want aperture to handle some of the incoming requests on its own,
without forwarding/proxying them to a remote backend. Those "local"
services can register themselves and will be given every request for
inspection. If a service decides to handle it locally, the request is
passed to that service and not forwarded.
This commit adds a DynamicPrice member to the Services struct and uses
its values to determine if a GRPCPricer or DefaultPricer should be
initialised. The commit also updates the sample-conf.yaml file with the
new config options.
The last bugfix added some explicit header fields in an attempt of
fixing an issue with error responses. Unfortunately they weren't
strictly needed for the fix but ended up causing issues in a non-error
case.
This commit removes those header fields again and makes sure the "auth
header not found in response" header doesn't occur anymore.
The target service name remains unused in its current form, but will be
required in order to verify that an incoming request with an LSAT
attached is authorized to access the service being attempted. We can
derive this from the request's host field, but we choose to extend the
methods with the additional parameter in order to prevent parsing the
host field again to determine which service is being accessed.
