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.

Default: '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.

Default: '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 该算子 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.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
