描述
open_socket_connectopen_socket_connectOpenSocketConnectOpenSocketConnectOpenSocketConnectopen_socket_connect opens a connecting socket to an accepting
socket on the computer HostNameHostNameHostNameHostNamehostNamehost_name, which listens on port
PortPortPortPortportport。
The following parameters can be set for 'GenParamName'"GenParamName""GenParamName""GenParamName""GenParamName""GenParamName".
- 'protocol'"protocol""protocol""protocol""protocol""protocol"：
-
Specifies the protocol to be used. The 'HALCON'"HALCON""HALCON""HALCON""HALCON""HALCON" protocol without
a specific address family, will use IPv4 or IPv6 automatically depending
on the network configuration of the computer. To use a specific address
family a '4' or '6' (for IPv4 or IPv6, respectively) must be appended to
the name of the protocol. For example, 'HALCON4'"HALCON4""HALCON4""HALCON4""HALCON4""HALCON4" designates a
HALCON connection over IPv4. Possible values for a generic socket
communication are 'UDP'"UDP""UDP""UDP""UDP""UDP" and 'TCP'"TCP""TCP""TCP""TCP""TCP" which also support
appended '4' and '6'. Alternatively, the usage of addresses for
IPv4 (e.g., '127.0.0.1'"127.0.0.1""127.0.0.1""127.0.0.1""127.0.0.1""127.0.0.1") or IPv6 (e.g., '::1'"::1""::1""::1""::1""::1")
for HostNameHostNameHostNameHostNamehostNamehost_name determines the address family to be used.
Both communication partners must use the same protocol.
To exchange data using generic sockets use send_datasend_dataSendDataSendDataSendDatasend_data and
receive_datareceive_dataReceiveDataReceiveDataReceiveDatareceive_data only.
默认值：
'HALCON'"HALCON""HALCON""HALCON""HALCON""HALCON"
- 'timeout'"timeout""timeout""timeout""timeout""timeout"：
-
Sets a timeout for this operation. The timeout is given in seconds or
as the string 'infinite'"infinite""infinite""infinite""infinite""infinite".
- 'tls_enable'"tls_enable""tls_enable""tls_enable""tls_enable""tls_enable"：
-
Controls the use of Transport Layer Security (TLS) for the new socket
connection. When 'tls_enable'"tls_enable""tls_enable""tls_enable""tls_enable""tls_enable" is set to 'true'"true""true""true""true""true", a
connection attempt using TLS is undertaken. This requires TLS support on
the server side. The generic parameter 'tls_certificate'"tls_certificate""tls_certificate""tls_certificate""tls_certificate""tls_certificate" may be
used to provide a path to a certificate to check the authenticity of the
server. Without the certificate, the connection will still be encrypted,
but the authenticity of the server can not be verified. The certificate must
be provided in PEM-format.
默认值：
'false'"false""false""false""false""false"
- 'string_encoding'"string_encoding""string_encoding""string_encoding""string_encoding""string_encoding"：
-
Sets the string encoding that is expected when sending and receiving
strings with this socket. It is used for send_tuplesend_tupleSendTupleSendTupleSendTuplesend_tuple and
receive_tuplereceive_tupleReceiveTupleReceiveTupleReceiveTuplereceive_tuple as well as send_datasend_dataSendDataSendDataSendDatasend_data and receive_datareceive_dataReceiveDataReceiveDataReceiveDatareceive_data。When the protocol 'HALCON'"HALCON""HALCON""HALCON""HALCON""HALCON" is used, the setting only has effect
on connections to HALCON versions prior to 18.11. If the connection
partner is detected to have HALCON version 18.11 or newer, UTF-8 is
used to encode tuples.
For the 'HALCON'"HALCON""HALCON""HALCON""HALCON""HALCON" protocol the listening socket must have been
created earlier with the operator open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept in another
HALCON process. To establish the connection, the HALCON process, in which the
accepting socket resides, must call socket_accept_connectsocket_accept_connectSocketAcceptConnectSocketAcceptConnectSocketAcceptConnectsocket_accept_connect。For a
detailed example, see open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept。
For generic sockets the socket to connect to can be any socket from the
same protocol type.
