The corresponding SMB interface can be used for Web connection and information communication between the client and the server.
In this step, when the target shared file is a general file, an SMB interface is specifically called, and a communication connection is established between the smart television and the target shared device through an SMB protocol. Specifically, in the embodiment of the present invention, the SMB interface is an SMB2 interface. The SMB2 interface compares in traditional SMB interface, calls SMB2 interface based on the interface that the SMB2 agreement established promptly, not only is compatible more equipment through the SMB2 agreement, has still improved the communication quality and the stability of data transmission when sharing data to the security has been promoted.
S104: and after the communication connection is established with the target sharing device, transmitting the target sharing file through the local area network.
After the communication connection between the smart television and the target sharing device is established, the target sharing file is transmitted through the local area network based on the connection channel, so that the target sharing file is shared between the smart television and the target sharing device.
The data sharing method provided by the embodiment of the invention is applied to the smart television and comprises the steps of determining the file type of a target shared file; the file types comprise multimedia files and general files, and the smart television and the sharing equipment are in the same local area network; when the target sharing file is a multimedia file, establishing communication connection with the target sharing equipment in the local area network through the UPnP interface; when the target shared file is a common file, establishing communication connection with the target shared device in the local area network through the SMB interface; and after the communication connection is established with the target sharing device, transmitting the target sharing file through the local area network.
The intelligent television respectively transmits data of different file types through the UPnP interface and the SMB interface, the intelligent television can be connected with sharing equipment of more equipment types, and simultaneously can transmit data of more file types, so that the diversity of the intelligent television connecting equipment and the diversity of transmission files are greatly increased. And data sharing is realized through the two interfaces, so that the smart television can be simultaneously connected with a plurality of sharing devices, and richer contents can be displayed by the smart television.

Specifically, the login information generally includes an IP address, a user name, and a password of the target sharing device. Specifically, the smart television can determine whether the login information is correct login information according to the user name and the password in the login information. If yes, communication connection can be established with the target sharing device in the local area network according to the IP address in the login information.
S206: and calling the SMB interface, and establishing communication connection with the target sharing equipment through the local area network according to the login information.
In this step, a communication connection is usually established with the target sharing device based on the IP address in the login information, and the SMB packet is transmitted to the target sharing device when the communication connection is established. And after receiving the SMB data packet, the target sharing equipment carries out unpacking processing, and then queries the main configuration file SMB.
S207: and when the target shared file is a file stored in the smart television, sending the target shared file to the sharing equipment through an interface called when the communication connection is established with the sharing equipment.
In this step, the smart television can share the file stored in the smart television to the target sharing device through the communication connection established through the SMB interface or the UPnP interface.
S208: and when the target shared file is a file stored by the sharing equipment, reading the target shared file through an interface called when the communication connection is established with the sharing equipment.
In this step, the smart television may access the target shared file in the target shared device through the communication connection established through the SMB interface or the UPnP interface, and perform an operation on the target shared file through the SMB interface or the UPnP interface.
According to the data sharing method provided by the embodiment of the invention, the intelligent television respectively transmits data of different file types through the UPnP interface and the SMB interface, so that the intelligent television can be connected with sharing equipment of more equipment types, and simultaneously can transmit data of more file types, and thus the diversity of the intelligent television connecting equipment and the diversity of transmission files are greatly increased.
