Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a network access method applied to a terminal, a network access device applied to a terminal, and a computer-readable storage medium.
Background
When the terminal initiates an HTTP network request, the server is required to perform domain Name resolution (dns Name system), and address data obtained after the domain Name resolution is returned to the terminal, so that the terminal can access the address data. When the terminal sends the HTTP network request, DNS domain name resolution is typically performed by a service node, which is typically a third party service node, and the third party service node may be a server of a network operator.
In carrying out the presently disclosed concept, the inventors have found that there are at least the following problems in the related art.
Time is consumed in the process of performing domain name resolution (DNS) by the third-party service node, and the access performance of the terminal is influenced. When the third-party service node performs DNS (domain name system) domain name resolution, the third-party service node performs domain name resolution and returns address data, so that the returned address data is not optimal address data, an access path accessed by the terminal through the address data is not an optimal path, and user experience is influenced. When the server IP corresponding to the address data changes, the address data returned to the terminal is invalid, so that the terminal fails to access the address data because the third-party service node is not updated in time.

Fig. 1 schematically illustrates a network access method applied to a terminal and an application scenario of a network access device applied to a terminal according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of an application scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, an application scenario of the embodiment of the present disclosure includes, for example, a terminal 110 and a third party service node 120.
According to the embodiment of the present disclosure, the terminal 110 may have various communication client applications installed thereon, such as a shopping application, a web browser application, a search application, an instant messaging tool, a mailbox client, social platform software, and the like (for example only).

The third party service node 120 parses the received domain name data to obtain a parsing result, where the parsing result includes address data corresponding to the domain name data, and returns the parsing result including the address data to the terminal 110. The terminal 110 may then access the network service through the address data.
It should be understood that the number of terminals and third party service nodes in fig. 1 is merely illustrative. There may be any number of terminals and third party service nodes, as desired for implementation.
Fig. 2 schematically shows a flowchart of a network access method applied to a terminal according to an embodiment of the present disclosure.
As shown in fig. 2, the network access method applied to the terminal according to the embodiment of the present disclosure may include, for example, operations S210 to S250.
In operation S210, when the network state of the terminal is the first network state, the network service is accessed through at least one initial address data one-to-one corresponding to at least one domain name data.
In operation S220, a network status of the terminal is monitored.
In operation S230, when it is monitored that the network state is changed from the first network state to the second network state, a first resolution request is sent to the service node, wherein the first resolution request includes at least one domain name data.
The first network status may be a 3G, 4G, 5G, etc. mobile cellular network, and the second network status may be a wireless local area network (e.g., a WiFi network). Alternatively, the first network status may be a wireless local area network (e.g., a WiFi network) and the second network status may be a 3G, 4G, 5G, etc. mobile cellular network.
When the network state of the terminal is changed, the terminal may send a first resolution request to the service node, where the first resolution request may include a plurality of domain name data.
The service nodes include, for example, local service nodes and third party service nodes. In one embodiment, the local service node may be a server of a banking institution and the third party service node may be a server of a network operator.
In the embodiment of the present disclosure, when monitoring that the network state is changed, the terminal may preferentially send the first resolution request to the local service node. The terminal may send the first resolution request to the third-party service node when the local service node fails or the resolution result of the domain name data is incorrect.
In operation S240, a first resolution result from the service node is received, where the first resolution result includes at least one target address data corresponding to at least one domain name data one to one, and the first resolution result is generated by performing domain name resolution on each domain name data in the at least one domain name data by the service node.
Next, in operation S250, the network service is accessed through the at least one destination address data when the network status is the second network status.
After the service node receives the first resolution request from the terminal, the service node may perform domain name resolution on domain name data in the first resolution request to obtain target address data corresponding to the domain name data. The serving node then sends the destination address data to the terminal so that the terminal stores the destination address data.
In the embodiment of the present disclosure, for at least one domain name data, the initial address data corresponding to the domain name data in the first network state and the target address data corresponding to the domain name data in the second network state may be different. For example, taking the domain name data a as an example, in the first network state, the initial address data corresponding to the domain name data a may be the address data a, and in the second network state, the target address data corresponding to the domain name data a may be the address data b. Because the address data corresponding to the domain name data in different network states are different, the service node can be requested again to perform domain name resolution in advance in the embodiment of the present disclosure after the network state of the terminal changes every time.
In the embodiment of the disclosure, after the network state of the terminal changes, the terminal may request the service node to perform domain name resolution in advance, and store the resolved target address data in the terminal, so that the terminal can directly obtain the pre-stored target address data when performing subsequent network access, and access the target address data.
For example, when the network state of the terminal is changed from the first network state to the second network state, the domain name resolution is performed in advance through the service node, and at least one target address data obtained through the resolution is stored in the terminal. The terminal is facilitated to access the network service through the at least one destination address data when the network state of the terminal is the second network state.
It can be understood that, according to the embodiment of the present disclosure, after the network state of the terminal changes, the domain name resolution is performed by requesting the service node in advance, and the target address data obtained by the resolution is stored in the terminal, so that when the target address data is accessed by a subsequent terminal, the stored target address data is directly obtained without waiting for the service node to perform the domain name resolution, thereby improving the access efficiency of the terminal.
In an embodiment of the disclosure, the at least one domain name data comprises at least one of: and the domain name data with the terminal access frequency being greater than the preset frequency or the domain name data with the terminal access frequency being greater than the preset frequency. The preset frequency may be a specific numerical value, and the preset frequency is, for example, 5, which means that 5 visits per day are averaged. The preset number of times may be, for example, specific data, and the preset number of times is, for example, 30, which indicates a total of 30 accesses in a past period of time.
That is, in another embodiment of the present disclosure, a domain name with a high access frequency or access frequency of a terminal is used as a domain name that needs to be resolved in advance. The domain name data is a domain name with higher subsequent terminal access probability. Therefore, the embodiment of the disclosure only needs to resolve the domain name with higher terminal access probability in advance, so as to improve the resolving efficiency, save resolving calculation resources, and save the storage space of the terminal for storing the target address data.
According to the embodiment of the disclosure, when the network state of the terminal is changed from the first network state to the second network state, the domain name is resolved in advance through the service node, and at least one target address data obtained through resolution is stored in the terminal. The terminal is facilitated to access the network service through the at least one destination address data when the network state of the terminal is the second network state.
Fig. 3 schematically shows a flowchart of a network access method applied to a terminal according to another embodiment of the present disclosure.
As shown in fig. 3, the network access method applied to the terminal according to the embodiment of the present disclosure may include, for example, operations S210 to S250 and operations S310 to S320. Operations S210 to S250 are, for example, the same as or similar to the operations described in fig. 2, and are not described again here. Operations S310 to S320 may be performed before operation S210, for example.
In operation S310, a second resolution request is sent to the service node when the terminal is started, where the second resolution request includes at least one domain name data.
In operation S320, a second resolution result from the service node is received, where the second resolution result includes at least one initial address data corresponding to at least one domain name data, and after the terminal is started, the network status of the terminal is the first network status.
According to the embodiment of the disclosure, domain name data can be requested to be resolved from the service node in advance when the terminal is started, and initial address data obtained by performing domain name resolution on the service node is stored in the terminal.
In one embodiment, the network state after the terminal is started may be a first network state, and the first network state may be a 3G, 4G, 5G, or other mobile cellular network. In the first network state, the domain name data corresponds to the initial address data. The second network status may be a wireless local area network (e.g., a WiFi network).
For example, taking the domain name data a as an example, in the first network state, the initial address data corresponding to the domain name data a is the address data a. And when the terminal is subsequently converted from the first network state to the second network state, the target address data corresponding to the domain name data A is the address data b in the second network state. According to the embodiment of the disclosure, when the network state is the first network state, the terminal may access the network service through at least one initial address data, and when the network state is the second network state, the terminal may access the network service through at least one target address data.
According to the embodiment of the disclosure, the address data corresponding to the domain name data in different network states are different. For example, the address data corresponding to the domain name data in the first network state is the initial address data, and the address data corresponding to the domain name data in the second network state is the destination address data.
Wherein, when the terminal is in the first network state, an access efficiency of accessing the network service through the at least one initial address data is higher than an access efficiency of accessing the network service through the at least one target address data. When the terminal is in the second network state, the access efficiency of accessing the network service through the at least one destination address data is higher than the access efficiency of accessing the network service through the at least one initial address data.
That is, in the first network state, the network service is accessed as a priority access path of the terminal through the initial address data. And in the second network state, accessing the network service through the target address data to serve as a priority access path of the terminal.
In the embodiment of the present disclosure, after the terminal receives the first parsing result from the service node, the first parsing result may be stored to the terminal. Then, when the storage time of the first analysis result exceeds a preset time period, the first analysis result stored in the terminal is deleted.
In the embodiment of the present disclosure, after the terminal receives the second parsing result from the service node, the second parsing result may be stored to the terminal. Then, when the storage time of the second analysis result exceeds a preset time period, the second analysis result stored in the terminal is deleted.
The preset time period is, for example, a TTL (time To live) time period, or may be a time period 90% of the TTL time period. The TTL time period is the time of the domain name resolution result retained in the DNS.

In case the terminal 410 fails to access the network service through the at least one initial address data returned by the local service node, the terminal 410 may send a second resolution request to the third party service node 440.
Specifically, in the case that the terminal 410 fails to access the plurality of devices 451, 452, 453 through at least one target address data or at least one initial address data returned by the local service node, it may indicate that the process of domain name resolution of the local service node fails, and at this time, the terminal 410 may send resolution requests (including the first resolution request and the second resolution request) to the third party service node 440, which is a fault-tolerant service node.
In another embodiment, when the local service node does not return the resolution result, it may be determined that the local service node fails, and the terminal 410 may send the resolution request (including the first resolution request and the second resolution request) to the third-party service node 440, which is a fault-tolerant service node.
In the embodiment of the disclosure, the number of access failures may be further determined, and the number of access failures is the number of failures in accessing the network service through the at least one target address data and/or the at least one initial address data returned by the local service node. And in the case that the access failure times exceed the preset threshold, prohibiting the terminal 410 from sending a resolution request to the local service node. The preset threshold may be specifically set according to the actual application, for example, the preset threshold may be 6 times, 10 times, and the like.
When the number of access failures exceeds a preset threshold, it indicates that the local service node has a fault, and in order not to affect the access of the terminal 410, the embodiment of the present disclosure prohibits the terminal 410 from continuing to send an analysis request to the local service node. Alternatively, the terminal 410 may send a resolution request (including the first resolution request and the second resolution request) to the third party service node 440.
In the embodiment of the present disclosure, since the plurality of devices 451, 452, 453 are devices in a banking service institution, when the IP addresses of the plurality of devices 451, 452, 453 are changed, it is difficult for the third party service node 440 to update the IP addresses of the plurality of devices 451, 452, 453 stored therein in time. If the terminal 410 requests the third party service node 440 to perform domain name resolution, the address data fed back by the third party service node 440 after performing domain name resolution is the non-updated address data, which may result in a failure of the terminal 410 to access the multiple devices 451, 452, 453 through the non-updated address data. Therefore, the terminal 410 according to the embodiment of the present disclosure preferably requests the local service node to perform domain name resolution, and indicates that the local service node has a fault when the number of access failures caused by the access of the terminal 410 through the address data returned by the local service node exceeds a preset threshold, and in order not to affect the access of the terminal 410, the embodiment of the present disclosure may prohibit the terminal 410 from continuing to send a resolution request to the local service node.
The embodiment of the disclosure provides domain name resolution service for the terminal through the local service node and the third-party service node. Specifically, under the condition that the local service node fails to perform domain name resolution, the terminal can continue to perform domain name resolution by requesting a third-party service node, and the terminal is guaranteed to successfully access the network service to a great extent.
According to the embodiment of the invention, before the actual network request, the domain name resolution of the hotspot domain name can be completed in advance, and the cache is updated regularly, so that the time consumption of domain name resolution is saved, the network request time is shortened, and the user experience is improved.
