Functions

func DebugLogging added in v0.4.6

Types

type LoggingConfig added in v0.4.6

type LoggingConfig struct {
	Level  string
	Format string

}

LoggingHandler returns an http.Handler that will print log messages containing the request information as well as response status and latency.

func (*LoggingHandler) ServeHTTP

func (h *LoggingHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)

type Params

type Params struct {

	// Addr is the listening address that the OPA server will bind to.
	Addr string

	// InsecureAddr is the listening address that the OPA server will bind to
	// in addition to Addr if TLS is enabled.
	InsecureAddr string

	// Authentication is the type of authentication scheme to use.
	Authentication server.AuthenticationScheme

	// Authorization is the type of authorization scheme to use.
	Authorization server.AuthorizationScheme

	// Certificate is the certificate to use in server-mode. If the certificate
	// is nil, the server will NOT use TLS.
	Certificate *tls.Certificate

	// Eval is a string to evaluate in the REPL.
	Eval string

	// HistoryPath is the filename to store the interactive shell user
	// input history.
	HistoryPath string

	// Output format controls how the REPL will print query results.
	// Default: "pretty".

	// Paths contains filenames of base documents and policy modules to load on
	// startup. Data files may be prefixed with "<dotted-path>:" to indicate
	// where the contained document should be loaded.
	Paths []string

	// Server flag controls whether the OPA instance will start a server.
	// By default, the OPA instance acts as an interactive shell.
	Server bool

	// Watch flag controls whether OPA will watch the Paths files for changes.
	// This flag is only supported if OPA instance is running as an interactive
	// shell. If this flag is true, OPA will watch the Paths files for changes
	// and reload the storage layer each time they change. This is useful for
	// interactive development.
	Watch bool

	// Logging configures the logging behaviour.
	Logging LoggingConfig

	// Output is the output stream used when run as an interactive shell. This
	// is mostly for test purposes.
	Output io.Writer
}
