Accepts an internet connection and creates a socket for that connection. Syntax

 accept [datagram] connections on port portNumber with message callbackMessage


on mouseUp
  accept connections on port 80 with message "connectionMade"
end mouseUp

on connectionMade pIPAddress
  put "Connection made:" && pIPAddress
end connectionMade

Parameters Bearbeiten

  • callbackMessage: The name of a message to be sent when a connection is made or a datagram is received.
  • portNumber: The TCP port number on which to accept connections.

Use the accept command when running a server, to accept TCP connections or UDP datagrams from other systems (or other processes on the same system).

Use the datagram option if you want to accept UDP datagrams.

When a connection is made or a datagram is received, the accept command creates a new socket that can be used to communicate with the other system (or process). When using the close socket, read from socket, or write to socket commands, you can refer to this socket with a socket identifier that looks like this:


where the connectionID is a number assigned by the accept command. (You only need to specify the connection number if there is more than one socket connected to a particular port and host.)

The callbackMessage is sent to the object whose script contains the accept command. Either one or two parameters are sent with this message. The first parameter is the IP address of the system or process making the connection. If a datagram is being accepted, the second parameter is the contents of the datagram.
