Figure 1 As shown, the application environment may include terminal 100, domain name resolution server 300, target server 400 and target device 200.

[0028] In an optional embodiment, terminal 100 can be used to send services to a target server address.

[0033] Figure 2 This is a flowchart illustrating a device connection method according to an exemplary embodiment. The device connection method is used in a target device, the target device including a target communication module, such as... Figure 2 As shown, it includes the following steps.

[0034] In step S201, in response to the communication connection instruction for the target server, the target server domain name corresponding to the target server is sent to the domain name resolution server so that the domain name resolution server can resolve the target server domain name.

[0035] In one specific embodiment, the communication connection instruction can be used to instruct the target device to establish a communication connection with the target server, and the target server can be used as a server to communicate with the target device.

[0036] In one specific embodiment, the domain name resolution server can be used to resolve the target server domain name. Optionally, the domain name resolution server can resolve the target server domain name through the mapping relationship between the server domain name and the server address. Optionally, the domain name resolution server can be the Domain Name System.

[0037] In step S203, if the number of times the domain name resolution server fails to resolve the target server domain name reaches a preset number, the preset cache address is obtained from the preset cache.

[0038] In one specific embodiment, the preset cache address may include a preset resolution address and / or a target server address. Specifically, the preset resolution address may be the server address corresponding to the target server domain name resolved by the domain name resolution server within a historical time period, and the target server address may be the server address corresponding to the target server domain name sent by the terminal device.

[0039] In an optional embodiment, when the preset cache address includes a preset resolution address and a target server address, establishing a communication connection with the target server based on the preset cache address may include: Establish a communication connection with the target server based on the preset resolution address; If establishing a communication connection with the target server based on the preset resolution address fails, a communication connection will be established with the target server based on the target server address.

[0040] In a specific embodiment, taking the preset resolution address as IP1 and the target server address as IP2 as an example, a communication connection can be established with the target server through IP1 first. If the communication connection with the target server through IP1 fails, a communication connection can be established with the target server through IP2.

[0041] In the above embodiments, when the preset cache address includes a preset resolution address and a target server address, the preset resolution address resolved by the domain name resolution server within a historical time period is used first to establish a communication connection with the target server, which can ensure the validity and reliability of the server address. If the communication connection with the target server fails to be established using the preset resolution address, the target server address sent by the terminal device is then used, which can improve the connection probability between the target device and the target server.

[0042] In step S205, a communication connection is established with the target server based on the preset cache address.

[0043] In a specific embodiment, taking the preset cache address as IP1 and / or IP2 as an example, a communication connection can be established with the target server based on IP1 and / or IP2.

[0044] In an optional embodiment, when the preset cache address is a preset resolution address or a target server address, establishing a communication connection with the target server based on the preset cache address may include: Establish a communication connection with the target server based on the preset resolution address; or, Establish a communication connection with the target server based on the target server address.

[0045] In a specific embodiment, taking the preset resolution address as IP1 and the target server address as IP2 as an example, when the preset cache address is IP1, a communication connection can be established with the target server through IP1, and when the preset cache address is IP2, a communication connection can be established with the target server through IP2.

[0046] In the above embodiments, when the preset cache address is the preset resolution address or the target server address, a communication connection can be established with the target server through the preset resolution address or the target server address, ensuring normal communication between the target device and the target server, thereby reducing device malfunctions.

[0047] In an optional embodiment, if the domain name resolution server successfully resolves the target server's domain name, the method may further include: Get the current resolved address; Establish a communication connection with the target server based on the current resolved address.

[0048] In one specific embodiment, the current resolution address can be the server address corresponding to the target server domain name obtained by the domain name resolution server resolving the target server domain name.

[0049] In the above embodiments, if the domain name resolution server successfully resolves the target server's domain name, it can establish a communication connection with the target server by using the currently resolved address, automatically adapting to changes in the server address and ensuring the validity of the address.

[0050] In an optional embodiment, the above method may further include: If the DNS server successfully resolves the target server's domain name, the preset DNS address in the preset cache is updated based on the current DNS address.

[0051] In a specific embodiment, taking the preset resolution address as IP2 and the current resolution address as IP3 as an example, the IP2 in the preset cache can be updated to IP3 based on IP3.

[0052] In the above embodiments, when the domain name resolution server successfully resolves the target server domain name, the preset resolution address in the preset cache can be updated to the current resolution address in real time to adapt to changes in the server address and ensure communication continuity.

[0053] In an optional embodiment, the above method may further include: When establishing a network connection based on network configuration parameters sent by the terminal device, receive the target server address sent by the terminal device; The target server address is stored in a preset cache based on the target communication module.

[0054] In one specific embodiment, network configuration parameters can be used to configure the network. Specifically, network configuration parameters may include WiFi name, WiFi password, and encryption method, etc.

[0055] In the above embodiments, during the process of establishing a network connection through network parameters sent by the terminal device, the target server address sent by the terminal device is stored in a preset cache based on the target communication module. In the event of an anomaly in the domain name resolution server, the target server can be retrieved from the preset cache, ensuring the continuity of the communication connection and avoiding service interruption caused by resolution anomalies.

[0056] In an optional embodiment, the above method may further include: When the target server address is updated, the receiving terminal device sends the target updated address corresponding to the target server domain name. The target server address is updated to the target update address based on the target communication module.

[0057] In one specific embodiment, the target update address can be the updated server address corresponding to the target server domain name.

[0058] In a specific embodiment, taking the target server address as IP2 and the target update address as IP4 as an example, IP2 can be updated to IP4 based on the target communication module.

[0059] In the above embodiments, when the target server address is updated, the target server address can be updated to the target updated address based on the target communication module. This proactively addresses the server address change scenario and ensures that even if the domain name resolution server malfunctions, the target device can still obtain the updated server address corresponding to the target server domain name, thus avoiding connection failure due to the expiration of the cached server address.

[0060] As can be seen from the technical solutions provided in the embodiments of this specification above, in response to a communication connection command for a target server, this specification sends the target server domain name corresponding to the target server to the domain name resolution server, so that the domain name resolution server can resolve the target server domain name. It can prioritize obtaining the address by resolving the domain name, ensuring the real-time nature and validity of the address. If the number of times the domain name resolution server fails to resolve the target server domain name reaches a preset number, it obtains a preset resolution address and / or the target server address from a preset cache. The preset resolution address is the server address corresponding to the target server domain name resolved by the domain name resolution server within a historical time period, and the target server address is the server address corresponding to the target server domain name sent by the terminal device. Based on the preset cached address, a communication connection is established with the target server. Even in the event of domain name resolution anomalies, communication can be established with the server using the cached address, ensuring continuous communication between the device and the server, improving the continuity and reliability of communication between the device and the server, and reducing device anomalies.
