Connecting method, apparatus of screen transmission device based on NFC, and computer device

A connecting apparatus of a screen transmission device based on Near Field Communication (NFC), comprising:

• a memory storing computer-readable instructions;
• and
• a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:
• touching an NFC tag, wherein the NFC tag is configured to either contain network information of the screen transmission device or not contain the network information of the screen transmission device;
• identifying whether the NFC tag contains network information of the screen transmission device;
• when the NFC tag contains the network information of the screen transmission device, acquiring the network information, and connecting with the screen transmission device according to the network information by calling a preset program to analyze the encrypted data, obtaining the network information, and calling the preset program to wirelessly connect with the screen transmission device according to the network information;
• sending screen projection information to the screen transmission device, so that the screen transmission device projects the screen projection information onto a display screen for playing;
• and
• when the NFC tag does not contain the network information of the screen transmission device, sending an acquisition request to the screen transmission device for encrypted data of the network information of the screen transmission device, receiving the encrypted data from the screen transmission device, and writing the encrypted data into the NFC tag,
• wherein the encrypted data is formed by the screen transmission device encrypting its own network information after receiving the acquisition request.

A non-transitory computer-readable medium storing computer-readable instructions, wherein the computer-readable instructions, when executed by a processor, cause the processor to perform operations comprising:

• touching a Near Field Communication (NFC) tag, wherein the NFC tag is configured to either contain network information of a screen transmission device or not contain the network information of the screen transmission device;
• identifying whether the NFC tag contains network information of the screen transmission device;
• when the NFC tag contains the network information of the screen transmission device, acquiring the network information, and connecting with the screen transmission device according to the network information by calling a preset program to analyze the encrypted data, obtaining the network information, and calling the preset program to wirelessly connect with the screen transmission device according to the network information;
• sending screen projection information to the screen transmission device, so that the screen transmission device projects the screen projection information onto a display screen for playing;
• and
• when the NFC tag does not contain the network information of the screen transmission device, sending an acquisition request to the screen transmission device for encrypted data of the network information of the screen transmission device, receiving the encrypted data from the screen transmission device, and writing the encrypted data into the NFC tag,
• wherein the encrypted data is formed by the screen transmission device encrypting its own network information after receiving the acquisition request.
