The Socket class enables code to make
socket connections and to read and write raw binary data. It is similar
to XMLSocket but does not dictate the format of
the received or transmitted data.
The Socket class is useful for working with servers that use binary protocols.
To use the methods of the Socket class, first use the constructor, new Socket
,
to create a Socket object.
SWF files in the local-with-filesystem sandbox may not use sockets.
Socket policy files on the target host specify the hosts from which SWF files
can make socket connections, and the ports to which those connections can be made.
The security requirements with regard to socket policy files have become more stringent
in the last several releases of Flash Player.
In all versions of Flash Player, Adobe recommends the use of a socket policy file;
in some circumstances, a socket policy file is required. Therefore, if you
are using XMLSocket objects, make sure that the target host provides a socket policy file
if necessary.
The following list summarizes the requirements for socket policy files
in different versions of Flash Player:
- In Flash Player 9.0.124.0 and later, a socket policy file is required for any Socket connection.
That is, a socket policy file on the target host is required no matter what port
you are connecting to, and is required even if you are connecting
to a port on the same host that is serving the SWF file.
- In Flash Player versions 9.0.115.0 and earlier, if you want to connect to a port number below 1024,
or if you want to connect to a host other than the one serving the SWF file,
a socket policy file on the target host is required.
- In Flash Player 9.0.115.0, even if a socket policy file isn't required,
a warning is displayed when using the Flash Debug Player if the target host
doesn't serve a socket policy file.
However, in Adobe AIR, content in the application
security sandbox (content
installed with the AIR application) are not restricted by these security limitations.
For more information related to security, see the following:

bytesAvailable:uint
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
The number of bytes of data available for reading in the input buffer.
Your code must access bytesAvailable
to ensure
that sufficient data is available before trying to read
it with one of the read
methods.
Implementation public function get bytesAvailable():uint
connected:Boolean
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Indicates whether this Socket object is currently connected.
A call to this property returns a value of true
if the socket
is currently connected, or false
otherwise.
Implementation public function get connected():Boolean
endian:String
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Indicates the byte order for the data; possible values are
constants from the flash.utils.Endian class,
Endian.BIG_ENDIAN
or Endian.LITTLE_ENDIAN
.
The default value is Endian.BIG_ENDIAN.
Implementation public function get endian():String
public function set endian(value:String):void

objectEncoding:uint
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Controls the version of AMF used when writing or reading an object.
Implementation public function get objectEncoding():uint
public function set objectEncoding(value:uint):void
See also
timeout:uint
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates the number of milliseconds to wait for a connection.
If the connection doesn't succeed within the specified time, the connection fails.
The default value is 20,000 (twenty seconds).
Implementation public function get timeout():uint
public function set timeout(value:uint):void
public function Socket(host:String = null, port:int = 0)
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Creates a new Socket object. If no parameters are specified, an initially disconnected socket
is created. If parameters are specified, a connection is attempted to the specified host and port.
Note: It is strongly advised to use the constructor form without parameters, then
add any event listeners, then call the connect
method with host
and port
parameters. This sequence guarantees that all event listeners will work
properly.
Parameters | host:String (default = null ) — A fully qualified DNS domain name or an IP address in the form
111.222.333.444. In Flash Player 9.0.115.0 and AIR 1.0 and later,
you can specify IPv6 addresses, such as rtmp://[2001:db8:ccc3:ffff:0:444d:555e:666f].
You can also specify null to connect to the host server
on which the SWF file resides. If the SWF file issuing this call is running in a web browser,
host must be in the same domain as the SWF file.
|
|
| port:int (default = 0 ) — The TCP port number on the target host used to establish a connection.
In Flash Player 9.0.124.0 and later, the target host must serve a socket policy file
specifying that socket connections are permitted from the host serving the SWF file
to the specified port. In earlier versions of Flash Player, a socket policy file is required
only if you want to connect to a port number below 1024,
or if you want to connect to a host other than the one serving the SWF file.
|
Events | connect:Event — Dispatched when a network connection has been established.
|
|
| ioError:IOErrorEvent — Dispatched when an input/output error
occurs that causes the connection to fail.
|
|
| securityError:SecurityErrorEvent —
Dispatched if a call to Socket.connect() attempts
to connect either to a server that doesn't serve a socket policy file,
or to a server whose policy file doesn't grant the calling host access to the specified port.
For more information about socket policy files, see the "Flash Player Security" chapter in
Programming ActionScript 3.0.
|
Throws | SecurityError — This error occurs in SWF content
for the following reasons:
- Local-with-filesystem files cannot communicate with the Internet. You can
work around this problem by reclassifying this SWF file as local-with-networking or trusted.
This limitation is not set for AIR application content in the application security sandbox.
- You cannot specify a socket port higher than 65535.
|
public function close():void
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Closes the socket. You cannot read or write any data after the close()
method
has been called.
The close
event is dispatched only when the server
closes the connection; it is not dispatched when you call the close()
method.
You can reuse the Socket object by calling the connect()
method on it again.
Throws | IOError — The socket could not be closed, or the socket was not open.
|
public function connect(host:String, port:int):void
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Connects the socket to the specified host and port.
If the connection fails immediately, either an event is dispatched
or an exception is thrown: an error event is dispatched if a host was
specified, and an exception is thrown if no host was specified.
Otherwise, the status of the connection is reported by an event.
If the socket is already connected, the existing connection is closed first.
Parameters
| host:String — The name or IP address of the host to connect to. If no host is specified,
the host that is contacted is the host where the calling file
resides. If you do not specify a host, use an event listener to
determine whether the connection was successful.
|
|
| port:int — The port number to connect to.
|
Events | connect:Event — Dispatched when a network connection has been
established.
|
|
| ioError:IOErrorEvent — Dispatched if a host is specified and an
input/output error occurs that causes the connection to fail.
|
|
| securityError:SecurityErrorEvent — Dispatched if a call to
Socket.connect() attempts to connect
either to a server that doesn't serve a socket policy file,
or to a server whose policy file doesn't grant the calling host access to the specified port.
For more information,
see the "Flash Player Security" chapter in Programming
ActionScript 3.0.
|
Throws | IOError — No host was specified and the connection failed.
|
|
| SecurityError — This error occurs in SWF content

The following example reads from and writes to a socket and outputs information
transmitted during socket events. Highlights of the example follow:
- The constructor creates a
CustomSocket
instance named socket
and passes the
host name localhost
and port 80 as arguments. Since CustomSocket
extends
Socket, a call to super()
calls Socket's constructor. - The example then calls the
configureListeners()
method, which adds listeners for
Socket events. - Finally, the socket
connect()
method is called with localhost
as the
host name and 80 as the port number.
Note: To run the example, you need a server running on the same domain
where the SWF resides (in the example, localhost
) and listening on port 80.
