TCPSocket
This API is available on Firefox OS for privileged or certified applications only.
Summary
The TCPSocket
interface provides access to a raw TCP socket.
The main entry point for this API is the navigator.mozTCPSocket
property which is a TCPSocket
object.
Note: Only certified apps can accept incoming connections on a port below 1024.
API overview
JavaScript
Copy Code
interface TCPSocket{ readonly attribute DOMString host; readonly attribute unsigned short port; readonly attribute boolean ssl; readonly attribute unsigned long bufferedAmount; readonly attribute DOMString binaryType; readonly attribute DOMString readyState; TCPSocket open(DOMString host, unsigned short port, [object options]); TCPServerSocket listen(unsigned short port, [object options, [unsigned short backlog]]); void upgradeToSecure(); void suspend(); void resume(); void close(); boolean send(in jsval data); attribute onopen; attribute ondrain; attribute ondata; attribute onerror; attribute onclose; };
Properties
TCPSocket.host
Read only- A string representing the host name of the server the socket is connected to.
TCPSocket.port
Read only- A number representing the port the socket is connected to.
TCPSocket.ssl
Read only- A boolean indicating whether the socket is encrypted with SSL (
true
) or not (false
). TCPSocket.bufferedAmount
Read only- The number of bytes of not-yet-sent data in the socket buffered.
TCPSocket.binaryType
Read only- The type of data used. Possible value is
arraybuffer
orstring
. TCPSocket.readyState
Read only- The socket state. Possible value is
connecting
,open
,closing
, orclosed
.
Events handler
TCPSocket.onopen
- A handler for the
open
event. After this event, the socket is ready to send and receive data. TCPSocket.ondrain
- A handler for the
drain
event. This event is triggered each time the buffer of data is flushed. TCPSocket.onerror
- A handler for the
error
event. TCPSocket.ondata
- A handler for the
data
event. This event is triggered each time data has been received. TCPSocket.onclose
- A handler for the
close
event.
Methods
TCPSocket.close()
- Closes the connection.
TCPSocket.open(host, port [, options])
- Returns a new
TCPSocket
object connected to the givenhost
at the givenport
. TCPSocket.listen(port [, options [, backlog]])
Requires FirefoxOS 1.2- Returns a new
TCPServerSocket
object listening at the givenport
. TCPSocket.resume()
- Resumes the
data
events. TCPSocket.send(data)
- Buffers data to be sent across the network.
TCPSocket.suspend()
- Pauses the
data
events. TCPSocket.upgradeToSecure()
Requires FirefoxOS 1.2- Enables secure on channel.
Specification
Not part of any specification yet; however, this API is discussed at W3C as part of the System Applications Working Group under the TCP and UDP Socket API (formerly known as the Raw Sockets API) proposal.
