func ListenAndServe Uses

func ListenAndServe(addr string, handler http.Handler) error

ListenAndServe refer http.ListenAndServe

func ListenAndServeTLS Uses

func ListenAndServeTLS(addr string, certFile string, keyFile string, handler http.Handler) error

ListenAndServeTLS refer http.ListenAndServeTLS

type Server Uses

type Server struct {

    SignalHooks map[int]map[os.Signal][]func()

    Network string
    // contains filtered or unexported fields

Server embedded http.Server

func NewServer Uses

func NewServer(addr string, handler http.Handler) (srv *Server)

NewServer returns a new graceServer.

func (*Server) ListenAndServe Uses

func (srv *Server) ListenAndServe() (err error)

ListenAndServe listens on the TCP network address srv.Addr and then calls Serve to handle requests on incoming connections. If srv.Addr is blank, ":http" is used.

func (*Server) ListenAndServeMutualTLS Uses

func (srv *Server) ListenAndServeMutualTLS(certFile, keyFile, trustFile string) (err error)

ListenAndServeMutualTLS listens on the TCP network address srv.Addr and then calls Serve to handle requests on incoming mutual TLS connections.

func (*Server) ListenAndServeTLS Uses

func (srv *Server) ListenAndServeTLS(certFile, keyFile string) (err error)

ListenAndServeTLS listens on the TCP network address srv.Addr and then calls Serve to handle requests on incoming TLS connections.

Filenames containing a certificate and matching private key for the server must be provided. If the certificate is signed by a certificate authority, the certFile should be the concatenation of the server's certificate followed by the CA's certificate.

If srv.Addr is blank, ":https" is used.

func (*Server) RegisterSignalHook Uses

func (srv *Server) RegisterSignalHook(ppFlag int, sig os.Signal, f func()) (err error)

RegisterSignalHook registers a function to be run PreSignal or PostSignal for a given signal.

func (*Server) Serve Uses

func (srv *Server) Serve() (err error)

Serve accepts incoming connections on the Listener l and creates a new service goroutine for each. The service goroutines read requests and then call srv.Handler to reply to them.
