Overview ▾

Package socket provides outbound network sockets.

This package is only required in the classic App Engine environment. Applications running only in App Engine "flexible environment" should use the standard library's net package.

func LookupIP 

func LookupIP(ctx context.Context, host string) (addrs []net.IP, err error)

LookupIP returns the given host's IP addresses.

type Conn

Conn represents a socket connection. It implements net.Conn. 

type Conn struct {
    net.Conn
}

func Dial 

func Dial(ctx context.Context, protocol, addr string) (*Conn, error)

Dial connects to the address addr on the network protocol. The address format is host:port, where host may be a hostname or an IP address. Known protocols are "tcp" and "udp". The returned connection satisfies net.Conn, and is valid while ctx is valid; if the connection is to be used after ctx becomes invalid, invoke SetContext with the new context.

func DialTimeout 

func DialTimeout(ctx context.Context, protocol, addr string, timeout time.Duration) (*Conn, error)

DialTimeout is like Dial but takes a timeout. The timeout includes name resolution, if required.

func (*Conn) KeepAlive 

func (cn *Conn) KeepAlive() error

KeepAlive signals that the connection is still in use. It may be called to prevent the socket being closed due to inactivity.

func (*Conn) SetContext 

func (cn *Conn) SetContext(ctx context.Context)

SetContext sets the context that is used by this Conn. It is usually used only when using a Conn that was created in a different context, such as when a connection is created during a warmup request but used while servicing a user request.
