nsIServerSocket 编辑

The nsIServerSocket interface implements a server socket that can accept incoming connections.

Inherits from: nsISupports

Implemented by: @mozilla.org/network/server-socket;1. To create an instance, use:

var serverSocket = Components.classes["@mozilla.org/network/server-socket;1"]
                             .createInstance(Components.interfaces.nsIServerSocket);

Method overview

Attributes

Methods

asyncListen()

This method puts the server socket in the listening state. It will asynchronously listen for and accept client connections. The listener will be notified once for each client connection that is accepted. The listener's onSocketAccepted() method will be called on the same thread that called asyncListen() (the calling thread must have an nsIEventTarget).

The listener will be passed a reference to an already connected socket transport (nsISocketTransport). See nsIServerSocketListener for more details.

void asyncListen(
  in nsIServerSocketListener aListener
);

Parameters

aListener

The listener to be notified when client connections are accepted.

close()

This method closes a server socket. This does not affect already connected client sockets (i.e., the nsISocketTransport instances created from this server socket). This will cause the onStopListening event to asynchronously fire with a status of NS_BINDING_ABORTED.

void close();

Parameters

None.

getAddress

Returns the address to which this server socket is bound. Since a server socket may be bound to multiple network devices, this address may not necessarily be specific to a single network device. In the case of an IP socket, the IP address field would be zeroed out to indicate a server socket bound to all network devices.  Therefore, this method cannot be used to determine the IP address of the local system. See nsIDNSService.myHostName() if this is what you need.

PRNetAddr getAddress();

Parameters

None.

Return value

The network address to which the socket is bound.

init()

Initializes a server socket.

void init(
  in long aPort,
  in boolean aLoopbackOnly,
  in long aBackLog
);

Parameters

aPort

The port of the server socket. Pass -1 to indicate no preference, and a port will be selected automatically.

aLoopbackOnly

If true, the server socket will only respond to connections on the local loopback interface. Otherwise, it will accept connections from any interface. To specify a particular network interface, use initWithAddress().

aBackLog

The maximum length to which the queue of pending connections may grow. This parameter may be silently limited by the operating system. Pass -1 to use the default value. The default value is 5.

initWithAddress

This method initializes a server socket and binds it to a particular local address (and hence a particular local network interface).

void initWithAddress(
  [const] in PRNetAddrPtr aAddr,
  in long aBackLog
);

Parameters

aAddr

The address to which this server socket should be bound.

aBackLog

The maximum length the queue of pending connections may grow to. This parameter may be silently limited by the operating system. Pass -1 to use the default value. The default value is 5.
