The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

It should be noted that in the examples of this application, "first", "second", etc. are used to distinguish similar objects, and not necessarily used to describe a specific sequence or sequence.

In addition, the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

FIG. 1 is a schematic structural diagram of a network architecture provided by an embodiment of the application. As shown in FIG. 1, the network architecture 10 includes a terminal 11, a gateway 12, a domain name resolution server 13, a first server 14 and a second server 15.

The terminal 11 in the embodiment of the present application may be a mobile phone. In other embodiments, the terminal 11 may be a server, a tablet computer, a notebook computer, a handheld computer, a personal digital assistant, a portable media player, a smart speaker, a navigation device, a display device, a smart bracelet and other wearable devices, virtual reality (Virtual Reality, VR) equipment, Augmented Reality (AR) equipment, pedometer, digital TV or desktop computer, etc.

The gateway 12 in the embodiment of the present application may be a server gateway or a proxy server.

The domain name resolution server 13 in the embodiment of the present application may be a HyperText Transfer Protocol Domain Name System (HTTPDNS) server or a local domain name system (LocalDNS) server. Among them, HTTPDNS is based on the domain name system of the Hypertext Transfer Protocol (Hyper Text Transfer Protocol, HTTP) protocol. The HTTP protocol is used for domain name resolution, and the domain name resolution request is sent directly to the HTTPDNS server, thereby bypassing the operator's local domain name system LocalDNS.

HTTPDNS (HTTP-based Domain Name System) is a traffic scheduling solution based on HTTP and domain name resolution tailored for mobile clients. It is used to solve the problems of abnormal local DNS (local domain name system) resolution and inaccurate traffic scheduling in the prior art. The principle of HTTPDNS is mainly implemented in the following way. The terminal accesses the HTTPDNS interface, obtains the IP address configured on the domain name configuration management system for the business, and sends an HTTP request to the obtained IP address.

The first server 14 may be a business server or a reverse proxy server, and the second server 15 may be a business server or a reverse proxy server.

The terminal 11 can be connected to the gateway 12, and the terminal 11 can send an access request to the gateway 12. The access request can be: the first access request corresponding to the IP address of the first server 14, or the IP address of the second server 15. Corresponding to the second access request, when the gateway 12 receives the first access request sent by the terminal 11, the gateway forwards the first access request to the first server 14. The first server 14 responds to the first access request and determines that the first access request is The corresponding first access result is requested, and the first access result is sent to the gateway 12, and then the gateway 12 may send the first access result to the terminal.

The terminal 11 may also be connected to the domain name resolution server 13. The terminal 11 may obtain the IP address list corresponding to the domain name through the domain name resolution server 13, and the terminal 11 may also store multiple IP address lists.

The gateway 12 can also be connected with the domain name resolution server 13 to perform corresponding signaling interaction.

Fig. 2 is a schematic flowchart of an IP address update method provided by related technologies. As shown in Fig. 2, the IP address update method includes:

S201. The terminal sends a domain name resolution request to a domain name resolution server; the domain name resolution request includes the target domain name; the server receives the domain name resolution request sent by the terminal.

S203. The domain name resolution server responds to the domain name resolution request, and based on the target domain name in the domain name resolution request, determines a target IP address list corresponding to the target domain name.

S205: The domain name resolution server sends the target IP address list to the terminal, and the terminal receives the target IP address list.

S207. The terminal starts a timer, and determines that the timer expires.

Among them, the running time of the timer can be preset by the terminal or configured by the domain name resolution server, and the running time of the timer can be 1 day, 7 days, or 14 days, etc.

S209. During the operation of the timer of the terminal, the target IP address list in the domain name resolution server is updated.

S211. The terminal sends a domain name resolution request to the server again; the server receives the domain name resolution request sent by the terminal; the domain name resolution request includes the target domain name.

In S211, the time when the terminal resends the domain name resolution request is the time when the timer expires.

S213. The domain name resolution server responds to the domain name resolution request, and based on the target domain name in the domain name resolution request, determines an updated target IP address list corresponding to the target domain name.

S215. The domain name resolution server sends the updated target IP address list to the terminal, and the terminal receives the updated target IP address list.

In the related art, if the target IP address list in the domain name resolution server is updated during the operation of the timer, but the target IP address list in the terminal has not been updated yet, the terminal still uses the target IP address list. Performing access will result in a high failure rate of terminal access.

FIG. 3 is a schematic diagram of the implementation process of an IP address update method provided by an embodiment of the application. As shown in FIG. 3, the method is applied to a terminal, and the method includes:

S301: The terminal sends a first access request to the gateway.

The first access request may be used to request the first access result corresponding to the first access request, and the first access result includes the resource that the terminal needs to access.

The terminal can store multiple mappings between domain names and IP address lists. For example, the terminal can store domain name A, domain name B, domain name C, etc., and store the mapping between domain name A and the first IP address list , The mapping between domain name B and the second IP address list, and the mapping between domain name C and the third IP address list. Each IP address list can include at least one IP address.

When the terminal needs to access the domain name B, the terminal can first inquire whether the domain name B exists internally, and after the query is found, it can access through the IP address in the second IP address list. However, when the terminal needs to access the domain name G, the terminal queries the internally stored domain name but does not find the domain name G. At this time, the terminal can send a domain name resolution request including the domain name G to the domain name resolution server. The domain name resolution server receives the domain name resolution request. , Send the IP address list corresponding to the domain name G to the terminal, so that the terminal can access through the IP address list corresponding to the domain name G. Further, the terminal may store the domain name G and the IP address list corresponding to the domain name G in internal storage (such as SDK), so that when accessing the domain name G next time, it can obtain the IP address list corresponding to the domain name G by querying the internal storage.

In the embodiment of the present application, the terminal may determine the IP address of the first server to be accessed, and send the first access request to the gateway based on the IP address of the first server. For example, before S301, the terminal may obtain the first IP address list from internal storage, determine the IP address of the first server from the first IP address list, and then use the IP address of the first server to access, that is, to the gateway Sending the access request, so that the gateway forwards the first access request to the first server, thereby establishing a connection between the terminal and the first server. It can be understood that the first IP address list may include the IP address of the first server. Among them, the first IP address list may be stored in a software development kit (Software Development Kit, SDK) of the terminal.

S303. The terminal receives the notification message and the first access result sent by the gateway; the notification message is used to indicate that the first IP address list is updated.

After receiving the first access request, the gateway may forward the first access request to the first server, and receive the first access result fed back by the first server after responding to the first access request.

In the embodiment of the present application, the notification message is used by the terminal to obtain the second IP address list obtained after updating the first IP address list from the domain name resolution server.

In an implementation manner, the gateway may integrate the access result and the notification message into one signaling message, and send the signaling message to the terminal. In another implementation manner, the gateway may send the access result and the notification message respectively through two signaling messages.

The first IP address list may be an IP address list corresponding to the gateway. For example, the IP address list corresponding to the gateway may be one IP address list or multiple IP address lists. The first IP address list may correspond to the gateway. A list of IP addresses in multiple IP address lists.

In an embodiment, the first IP address list may include the IP address of the first server, so that after receiving the notification message, the terminal may determine the first IP address list based on the IP address of the first server.

In another implementation manner, the first IP address list may not include the IP address of the first server, but the notification message may include the first domain name, so that after receiving the notification message, the terminal can determine the first domain name according to the first domain name. The first IP address list.

S305. The terminal obtains a domain name resolution result from the domain name resolution server based on the notification message; the domain name resolution result includes the second IP address list obtained after updating the first IP address list.

Wherein, the domain name resolution result includes at least the second IP address list. The second IP address list may or may not include the IP address of the first server.

In the embodiment of the present application, after the terminal receives the notification message, the terminal determines that the first IP address list is updated, and then obtains the second IP address list obtained after updating the first IP address list from the domain name resolution server, so that the terminal The second IP address list can be obtained in time, and thus the access success rate of the terminal can be improved.

FIG. 4 is a schematic diagram of the implementation process of another method for updating an IP address provided by an embodiment of the application. As shown in FIG. 4, the method includes:

S401. The domain name resolution server sends a notification message to the gateway; the gateway receives the notification message sent by the domain name resolution server.

The notification message is used to indicate that the first IP address list is updated, and is used for the terminal to obtain the second IP address list obtained after updating the first IP address list from the domain name resolution server.

In an implementation manner, the notification message may not include the first domain name corresponding to the first IP address list, and the terminal may determine the first domain name corresponding to the first IP address list through the IP address of the first server. For example, since a mapping between the first domain name and the first IP address list is stored inside the terminal, the terminal may determine the first domain name corresponding to the first IP address list based on the IP address of the first server and the mapping. In another implementation manner, the notification message may include the first domain name, so that the terminal can parse the notification message to obtain the first domain name.

In an implementation manner, the domain name resolution server may generate a notification message when determining that the first IP address list is updated, and send the notification message to the gateway. The update of the first IP address list may be: adding an IP address to the first IP address list, reducing the IP address in the first IP address list, or changing the IP address in the first IP address list.

In an example process, the first IP address list may include M IP addresses, each of the M IP addresses corresponds to a service server, and the domain name resolution server may receive M corresponding to the M IP addresses. In the service server, any service server sends the change message of the IP address in the first IP address list through the gateway, so that the domain name resolution server updates the first IP address list based on the change message. Among them, M is an integer greater than or equal to 1. In another implementation process, the domain name resolution server may receive an IP address change message sent by another device, and update the first IP address list based on the change message.

In another example process, the second IP address list may include N IP addresses, and each IP address of the N IP addresses corresponds to a service server. Wherein, N is an integer greater than or equal to 1.

S403: The terminal sends a first access request to the gateway; the gateway receives the first access request sent by the terminal.

The embodiment of the present application does not limit the sequence in which the gateway receives the notification message and the first access request.

S405. The gateway sends a notification message and the first access result to the terminal; the terminal receives the notification message and the first access result sent by the gateway.

It should be understood that the gateway sends the notification message and the first access result to the terminal after receiving the notification message and after receiving the first access request sent by the terminal. The first access result corresponds to the first access request.

S407. The terminal obtains a domain name resolution result from the domain name resolution server based on the notification message; the domain name resolution result includes the second IP address list obtained after updating the first IP address list.

In the embodiment of this application, through the interaction process between the terminal, the gateway, and the domain name resolution server, the domain name resolution server sends a notification message to the gateway when it determines that the first IP address list is updated, so that the terminal passes through the gateway. Receive the notification message, and obtain the second IP address list obtained after updating the first IP address list based on the notification message, so that the terminal can also be updated in time after the first IP address in the domain name resolution server is updated The second IP address list can improve the access success rate of the terminal.

FIG. 5 is a schematic diagram of the implementation process of another method for updating an IP address provided by an embodiment of the application. As shown in FIG. 5, the method includes:

S501: The domain name resolution server sends a notification message to the gateway.

The notification message is used to indicate that the first IP address list is updated, and is used for the terminal to obtain the second IP address list obtained after updating the first IP address list from the domain name resolution server after receiving the notification message sent by the gateway.

S503. The terminal determines the IP address of the first server from the first IP address list.

The communication protocol between the terminal and the gateway may be a gateway protocol (Gateway to Gateway Protocol, GGP) or other network protocols.

The SDK of the terminal can store the mapping between each of the multiple domain names and each IP address list. The terminal may determine the first domain name to be accessed based on the user's operation on the terminal, so as to determine the first IP address list corresponding to the first domain name among multiple mappings. For example, in the case where the first domain name is www.baidu.com, the terminal can determine the IP address list corresponding to the domain name www.baidu.com from multiple mappings stored in the SDK, which can be based on the obtained www.baidu. Visit an IP address in the IP address list corresponding to com.

In the embodiment of the present application, in the first IP address list, the first IP address list includes not only at least one IP address, but also at least one weight parameter corresponding to the at least one IP address. The terminal may be based on the at least one weight. The parameter determines the IP address to be accessed first. If the access fails based on the IP address that is accessed first, the IP address of the second access is determined based on at least one weight parameter until the access is successful. The terminal may randomly select one of the at least one IP address as a connection based on a weighted random algorithm or a random weighted algorithm.

S505: The terminal may send a first access request to the gateway based on the IP address of the first server. The gateway receives the first access request sent by the terminal.

The first IP address list may include: M IP addresses and M weight parameters one-to-one corresponding to the M IP addresses, where M is an integer greater than or equal to 1; the terminal may be based on the M weight parameters from the M IP addresses , The IP address of the first server is determined, and the first access request may be sent to the gateway based on the IP address of the first server.

After the gateway receives the first access request, it can determine that the service server accessed by the terminal is the first server based on the IP address of the first server in the first access request. Then, the gateway may forward the first access request to the first server. After receiving the first access request, the first server responds to the first access request, determines the first access result based on the first access request, and then sends the first access request to the gateway. One visit result.

S507: The gateway sends a notification message and the first access result to the terminal; the terminal receives the notification message and the first access result sent by the gateway.

S509. The terminal determines the first domain name corresponding to the first IP address list based on the notification message.

After receiving the notification message, the terminal may trigger the process of determining the domain name corresponding to the IP address of the first server. In an implementation manner, the terminal may determine the first domain name corresponding to the IP address of the first server based on the mapping between the first domain name stored in the terminal and the first IP address list.

S511. The terminal sends a domain name resolution request to the domain name resolution server; the domain name resolution request includes the first domain name; and the domain name resolution server receives the domain name resolution request sent by the terminal.

Among them, the communication protocol between the terminal and the domain name resolution server is HTTP. HTTP is the most widely used network transmission protocol on the Internet, and all WWW documents comply with this standard. With the rapid development of Internet technology, network services have become an indispensable service in people's lives. Currently, Internet companies usually use domain names to provide services to users.

S513. The domain name resolution server sends a domain name resolution result to the terminal; the terminal receives the domain name resolution result sent by the domain name resolution server.

Wherein, the domain name resolution result includes the second IP address list obtained after updating the first IP address list.

If the DNS data (for example, the second IP address list) sent by the domain name resolution server to the terminal is not verified, it is easy to be tampered with and forged by a third party. To solve this problem, when the domain name resolution server sends the second IP address list to the terminal, the second IP address list can be encrypted using asymmetric encryption. The encryption method can be that the domain name resolution server uses a private key to encrypt the second IP address list. The address list is encrypted, and the terminal uses the public key to decrypt the encrypted data, or the encryption method may be that the domain name resolution server uses the public key to encrypt the second IP address list, and the terminal uses the private key to decrypt the encrypted data.

When the domain name resolution server is encrypted with the private key, the domain name resolution server can first perform a hash calculation on the second IP address list to obtain the first hash value; then it can use the private key to encrypt the first hash value to obtain the first signature ; Then, based on the first signature and the second IP address list, for example, the first signature and the second IP address list are encoded to determine the domain name resolution result. Wherein, the domain name resolution result may include the first signature and the second IP address list.

S515. The terminal verifies the domain name resolution result, and after the verification is successful, updates the first mapping stored in the terminal to the second mapping.

Wherein, the first mapping may include: mapping between the domain name and the first IP address list, and the second mapping may include: the mapping between the domain name and the second IP address list.

Both the first mapping and the second mapping may be stored in the domain name resolution information or domain name resolution module of the SDK.

When the terminal uses the public key to decrypt, the terminal can first determine the public key corresponding to the domain name resolution server; then the public key can be used to decrypt the first signature to obtain the first hash value; then the hash value of the second IP address list can be calculated , To obtain the second hash value; if the first hash value and the second hash value are the same, it is determined that the verification of the domain name resolution result is successful.

In an implementation manner, the public key corresponding to the domain name resolution server may be stored inside the terminal, and the terminal may obtain the public key corresponding to the domain name resolution server from its inside. In an implementation scenario, the public key can be extracted from a digital certificate stored inside the terminal. In another embodiment, the public key corresponding to the domain name resolution server may be sent by the domain name resolution server to the terminal, and the public key may be included in the domain name resolution result, or the domain name resolution server may separately send the public key to the terminal. In another embodiment, the domain name resolution server may also send a digital certificate to the server, and the digital certificate may include a public key, so that the terminal may obtain the public key through the digital certificate, where the digital certificate may be included in the domain name resolution result, Or the domain name resolution server separately sends the digital certificate to the terminal.

After S515, the terminal can access the first domain name based on the second IP address list.

Wherein, if an IP address is included in the second IP address list, then this IP address is the IP address of the first server, and the terminal can use this IP address in the IP address list for access. If the second IP address list includes at least two IP addresses, the terminal may determine the first weight parameter based on the at least two weight parameters; then, from the at least two IP addresses, determine the first to-be-accessed corresponding to the first weight parameter IP address, using the first IP address to be visited for access.

In one embodiment, when the terminal fails to access the first IP address to be accessed, it can determine a second weight parameter other than the first weight parameter from the at least two weight parameters; In the IP address, the second IP address to be accessed corresponding to the second weight parameter is determined, and the second IP address to be accessed is used for access.

In this way, since the terminal modifies the first IP address list stored in it to the second IP address list, the terminal can access through the second IP address list when it determines an access request for the domain name next time.

After the terminal updates the first IP address list to the second IP address list, if it does not notify the gateway in the second IP address list, the gateway does not know whether the terminal has updated the first IP address list. In order to solve this problem, the IP address update method may further include the following steps: the terminal sends an update complete message to the gateway; the gateway receives the update complete message sent by the terminal; the update complete message is used to instruct the terminal to complete the stored first IP address list Update.

The timing for the terminal to send the update completion message to the gateway may be after the terminal receives the domain name resolution result sent by the domain name resolution server, or after the terminal updates the first mapping stored internally to the second mapping.

After receiving the update complete message, the gateway may send the second access result to the terminal after receiving the second access request sent by the terminal based on the IP address of the second server based on the update complete message. After that, after the gateway again receives the notification message sent by the domain name resolution server and receives the access request of the terminal, it sends the notification message to the terminal.

In the embodiment of the present application, through the interaction process between the terminal, the gateway, and the domain name resolution server, since the second IP address list may include at least one IP address and at least one weight parameter corresponding to the at least one IP address, so The terminal can use the weighted random algorithm to determine the first IP address to be accessed from the second IP address list, which avoids that in related technologies, each access of the terminal is based on the access from the first IP address, resulting in the first IP address The corresponding gateway generates a request for aggregation. In addition, since the terminal verifies the second IP address list sent by the domain name resolution server, the second IP address is prevented from being tampered with by a third party.

FIG. 6 is a schematic diagram of a process for obtaining a second IP address list by a terminal according to an embodiment of the application. As shown in FIG. 6, the manner in which the terminal obtains the second IP address list can be implemented through the following steps S601 to S611:

S601. The terminal sends a DNS request to the domain name resolution server.

The DNS request may include a domain name, for example, the domain name may be www.domain.com, and the DNS request may be the domain name resolution request in the foregoing embodiment.

S603. After receiving the DNS request, the HTTPDNS server queries the second IP address list corresponding to the domain name in the DNS request.

As shown in FIG. 6, there are three IP addresses in the second IP address list, and the ratios are IP1, IP2, and IP3. The weights of these three IP addresses (corresponding to the weight parameters of the foregoing embodiment) are 0.4, 0.3, and 0.3, respectively.

S605. The HTTPDNS server may use the private key to encrypt the second IP address list.

The encryption method is that the HTTPDNS server calculates the hash value of the second IP address list to obtain the first hash value, and encrypts the first hash value to obtain the first signature.

S607. The HTTPDNS server may return the result of the DNS request to the terminal.

The returned result may be the domain name resolution result, and the domain name resolution result includes the first signature and the second IP address list.

S609. The terminal uses the public key to decrypt and verify.

The method of decryption and verification is: determine the public key corresponding to the domain name resolution server; use the public key to decrypt the first signature to obtain the first hash value; calculate the hash value of the updated IP address list to obtain the second hash Value; if the first hash value and the second hash value are the same, it is determined that the verification of the domain name resolution result is successful.

The HTTPDNS server may issue a public key, or the HTTPDNS server may issue a certificate, so that the terminal obtains the public key through the certificate.
