Covert json to string map (keys are json paths to access element, values are element), ie input json = `{ "credentials": { "account_types": [ "admin", "management", "service", "debug" ], "name": "admin" }, "server": { "ip": "192.168.56.101", "port": 1234 }}`, output = map[string]string{"credentials.name":"admin", "credentials.account_types":"admin,management,service,debug", "server.ip":"192.168.56.101", "server.port":"1234"} Notes and limitations: * Value is always represented as a string.
