Referring to fig. 2, fig. 2 is a flowchart of a network access method according to an embodiment of the present application, where the method is applied to the electronic device 100 shown in fig. 1. It should be noted that, the network access method provided in the embodiment of the present application is not limited to the sequence shown in fig. 2 and the following, and the specific flow and steps of the network access method are described below in conjunction with fig. 2.
Step S100, responding to a network access request for accessing a wide area network service, and acquiring a domain name set corresponding to the network access request, wherein the domain name set comprises a plurality of domain names.
In this embodiment, the wide area network service may be a data service provided by platforms such as naughty, jindong, tremble, fighting fish TV, google, and dog search. Referring to fig. 3, in a wan service system, an electronic device can communicate with a plurality of CDN servers, and a source server for storing source data of a wan service, where each CDN server is configured to manage a plurality of node servers, and the node servers are configured to cache part of data of the wan service, for example, static data of the wan service. And the plurality of domain names included in the domain name set may be a plurality of CDN domain names directed to CDN servers and source domain names directed to source servers (as shown in fig. 4).
Step S200, access is initiated to the wide area network service through the domain names in sequence, and an access result of the domain name which has initiated the access in the domain names is obtained.
In this embodiment of the present application, the access to the wan service may be initiated sequentially by a plurality of domain names, for example, according to a preset order, or may be initiated according to a random order. However, in order to further improve the access efficiency of the wan service, in the embodiment of the present application, it is preferable to initiate access to the wan service according to the priority order.
When access is initiated to the wide area network service in the order of priority, step S200 may include three sub-steps of step S210, step S220, and step S230.
Step S210, acquiring the priority orders of the domain names.
For step S210, as a first optional implementation manner, in this embodiment of the present application, the priority order of the multiple domains may be preset at the source server, for example, for the domains pointing to the CDN servers, the priority order of the corresponding CDN domains may be set according to the number of operators of the CDN servers, the service capability evaluation result of the CDN server operators, the number of node servers managed by the CDN servers, and other evaluation factors, and finally, the priority of the domain pointing to the source server in the multiple domains is set to the lowest level. Based on this, it can be appreciated that the plurality of domain name books included in the domain name set carry a pre-set priority order.
For step S210, as a second alternative implementation manner, in this embodiment of the present application, the priority order of the multiple domain names may also be determined in real time by the electronic device. Based on this, step S210 further includes three sub-steps of step S211, step S212, and step S213.
Step S211, performing connection speed test on each domain name pointing to the CDN server in the plurality of domain names.
In this embodiment of the present application, the connection speed test method may download a test file from each CDN server, determine the download time length of the test file, or perform a connection speed test on each domain name pointing to the CDN server in the multiple domain names by using a "ping" command.
Step S212, according to the connection speed test result, the priority order of each domain name pointing to the CDN server is obtained. It can be understood that in the embodiment of the present application, the order of priority of the corresponding domain names is set according to the connection speed of the CDN server.
In step S213, the priority of the domain name pointing to the source station server among the plurality of domain names is set to the lowest level, so as to avoid network congestion caused by excessive pressure of the source station server.
Step S220, according to the priority order, the access is initiated to the wide area network service through the plurality of domain names in turn until the access is successful or the access of the plurality of domain names fails, and the access result of the domain names which have initiated the access in the plurality of domain names is obtained. In this embodiment of the present application, after each access to the wan service is initiated through a domain name, the access result of the domain name may be obtained immediately and stored. An access procedure provided in step 200 will be briefly described below taking as an example the initiation of an access to a wide area network service via a plurality of domain names included in the set of domain names shown in fig. 4.
Firstly, acquiring the priority order of a plurality of domain names, specifically, the priority of a CDN server 1 domain name, a CDN server 2 domain name and a CDN server 3 domain name to a source station server domain name is sequentially reduced. And after that, acquiring the domain name of the CDN server 1, sending the domain name of the CDN server 1 to a domain name resolution server for domain name resolution, acquiring an IP address corresponding to the CDN server 1, and returning to the electronic equipment to enable the electronic equipment to access the server corresponding to the IP address, namely, the CDN server 1, if the static data of the wide area network service are cached in a plurality of node servers managed and controlled by the CDN server 1, and the static data are successfully returned to the electronic equipment, the access is successful, namely, the access is stopped, and if the access fails, the steps are repeated through the domain name of the CDN server 2.
It should be noted that, in the above access process, after the domain name resolver obtains the IP address corresponding to the CDN server 1, the domain name resolver may directly access the server corresponding to the IP address, that is, the CDN server 1, if static data of the wide area network service is cached in a plurality of node servers managed by the CDN server 1, and the static data is successfully returned to the electronic device, the access is successful, that is, the access is stopped, and if the access fails, the above steps are repeated by continuing to pass through the domain name of the CDN server 2.
And step S300, deleting the unavailable domain name from the domain name set according to the access result.
In the embodiment of the present application, the domain name that is not possible is a domain name that initiates access failure to the wan service. Based on this, in the embodiment of the present application, step S300 may include three sub-steps of step S310, step S320, and step S330.
In step S310, all target domain names included in the plurality of domain names are determined, the target domain names being domain names that initiate access failure to the wide area network service.
Step S320, performing availability detection on all the target domain names.
In this embodiment of the present application, the detection of the availability of resolution of all target domain names may be downloading a test file from a server corresponding to each target domain name, and taking the download result as the network access feedback information. Based on this, step S320 may include obtaining, for each target domain name, network access feedback information corresponding to the target domain name, and obtaining an availability detection result of the target domain name according to the network access feedback information.
Step S330, deleting the target domain name whose availability detection result is unavailable from the domain name set.
Optionally, in an embodiment of the present application, after step S300, the network access method further includes step S400 and step S500.
Step S400, judging whether the domain name set is empty.
Step S500, if the domain name set is empty, the domain name set corresponding to the wide area network service is re-acquired.
For step S500, as a first optional implementation manner, in this embodiment of the present application, when the domain name set is empty, a real-time domain name acquisition request may be initiated to the source station server to reacquire the domain name set corresponding to the wan service.
In order to improve the obtaining efficiency of the domain name set, in the embodiment of the present application, the network access method may further include step S600 and step S700.
Step S600, a domain name acquisition request is initiated to a source station server according to a preset time interval, and a domain name set corresponding to the wide area network service is acquired.
Step S700, replacing the domain name set acquired earlier with the domain name set acquired later.
In an exemplary embodiment of the present application, a domain name acquisition request may be initiated to a source station server at a first time point, a domain name set corresponding to a wide area network service may be acquired as a first domain name set, and stored in a local domain name storage space preset by an electronic device, after a preset time interval, a domain name acquisition request may be initiated to the source station server at a second time point, to acquire a domain name set corresponding to the wide area network service, as a second domain name set, and the first domain name set is replaced by the second domain name set.
Further, it is understood that the preset time interval may be specifically set according to a class of the wide area network service, a current access time, and the like, where the class of the wide area network service may include a shopping class (e.g., panned, jindong), an entertainment class (e.g., tremble, fighting fish TV), a search class (e.g., google, hundred degrees), and the like. Based on this, in the embodiment of the present application, the type of the wan service may be further determined, and meanwhile, the current access time may be obtained, and a preset time interval may be set according to the type of the wan service and the current access time.
For example, for a certain wan service, if the category of the wan service is shopping or entertainment and the current access time is 8.00-18.00, the preset time interval is set to a first time length, if the category of the wan service is shopping or entertainment and the current access time is 18.00-24.00, the preset time interval is set to a second time length, and if the category of the wan service is shopping or entertainment and the current access time is 24.00-8.00, the preset time interval is set to a third time length, wherein the third time length is less than the first time length, and the first time length is less than the second time length.
Based on the settings of step S600 and step S700, in the embodiment of the present application, as a second optional implementation manner, when the domain name set is empty, the domain name set corresponding to the wan service is further obtained again in a local domain name storage space preset by the electronic device.
Through the arrangement, after the access to the wide area network service is initiated by the plurality of domain names in turn for the first time and the plurality of domain names are determined to be unavailable, the access to the wide area network service can be initiated again by the plurality of domain names included in the re-acquired domain name set, so that the purpose of improving the access efficiency of the wide area network service on the basis of ensuring the normal access of the wide area network service is achieved.
