The gateway 12 in the embodiments of the present application may be a server gateway or a proxy server.
The domain name resolution server 13 in the embodiments of the present application may be a hypertext transfer protocol domain name system (HyperText Transfer Protocol Domain Name System, http dns) server or a local domain name system (LocalDNS) server. Wherein the HTTP dns is based on the domain name system of the hypertext transfer protocol (Hyper Text Transfer Protocol, HTTP) protocol, uses the HTTP protocol for domain name resolution, and the domain name resolution request is directly sent to the HTTPDNS server, thereby bypassing the operator's local domain name system LocalDNS.
HTTP dns (HTTP-based domain name system) is a traffic scheduling solution based on HTTP and domain name resolution tailored to mobile clients, for solving the problems of abnormal resolution and inaccurate traffic scheduling of the LocalDNS (local domain name system) in the prior art. The principle of the HTTPDNS is mainly realized by the following way that a terminal accesses an HTTPDNS interface, acquires an IP address configured by a service on a domain name configuration management system, and sends an HTTP request to the acquired IP address.
The first server 14 may be a service server or a reverse proxy server and the second server 15 may be a service server or a reverse proxy server.
The terminal 11 may be connected to the gateway 12, and the terminal 11 may send an access request to the gateway 12, where the access request may be: 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 determines a first access result corresponding to the first access request in response to the first access request, and sends the first access result to the gateway 12, and then the gateway 12 may send the first access result to the terminal.
The terminal 11 may be connected to the domain name resolution server 13, the terminal 11 may obtain an IP address list corresponding to the domain name through the domain name resolution server 13, and the terminal 11 may store a plurality of IP address lists.
The gateway 12 may also be connected to a domain name resolution server 13 for corresponding signaling interactions.
Fig. 2 is a flow chart of an IP address updating method provided in the related art, as shown in fig. 2, the IP address updating method includes:
s201, a terminal sends a domain name resolution request to a domain name resolution server; the domain name resolution request comprises a target domain name; and the server receives a domain name resolution request sent by the terminal.
S203, the domain name resolution server responds to the domain name resolution request, and determines a target IP address list corresponding to the target domain name based on the target domain name in the domain name resolution request.
S205, the domain name resolution server sends a 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 is overtime.
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.
S209, in the running process 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 a domain name resolution request sent by a terminal; the domain name resolution request includes the target domain name.
In S211, the timing at which the terminal transmits the domain name resolution request again is the timing at which the timer expires.
S213, the domain name resolution server responds to the domain name resolution request, and determines an updated target IP address list corresponding to the target domain name based on the target domain name in the domain name resolution request.
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 destination IP address list in the domain name resolution server is updated during the operation of the timer, but the destination IP address list in the terminal is not updated yet, the terminal accesses through the destination IP address list, which may result in a high failure rate of the terminal access.
Fig. 3 is a schematic implementation flow chart of an IP address updating method provided in an embodiment of the present application, where, 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 for requesting a first access result corresponding to the first access request, where the first access result includes a resource that the terminal needs to access.
The terminal may store a plurality of mappings between domain names and the IP address list, for example, the terminal may store a domain name a, a domain name B, a domain name C, etc., and store a mapping between the domain name a and the first IP address list, a mapping between the domain name B and the second IP address list, and a mapping between the domain name C and the third IP address list. At least one IP address may be included in each IP address list.
When the terminal needs to access the domain name B, the terminal can firstly query whether the domain name B exists internally, and access the domain name B through the IP address in the second IP address list after the terminal queries. However, when the terminal needs to access the domain name G, the terminal queries the domain name stored in the terminal and does not find the domain name G, at this time, the terminal may send a domain name resolution request including the domain name G to the domain name resolution server, and after receiving the domain name resolution request, the domain name resolution server sends an IP address list corresponding to the domain name G to the terminal, so that the terminal may 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 an internal storage (for example, SDK), so that when the domain name G is accessed next time, the IP address list corresponding to the domain name G may be obtained by querying the internal storage.
In the embodiment of the 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 perform obtaining the first IP address list from the internal storage, determine the IP address of the first server from the first IP address list, and then access with the IP address of the first server, that is, send an access request to the gateway, 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 appreciated that the first list of IP addresses may include the IP address of the first server. Wherein the first list of IP addresses may be stored in a software development kit (Software Development Kit, SDK) of the terminal.
S303, the terminal receives a notification message and a first access result sent by the gateway; the notification message is used to indicate that the first list of IP addresses is updated.
After the gateway receives the first access request, the first access request may be forwarded to the first server, and a first access result fed back by the first server after responding to the first access request is received.
In the embodiment of the application, the notification message is used for the terminal to acquire the second IP address list obtained after updating the first IP address list from the domain name resolution server.
In one embodiment, 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 embodiment, the gateway may send the access result and the notification message separately via 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 may be a plurality of IP address lists, and the first IP address list may be one IP address list of the plurality of IP address lists corresponding to the gateway.
In one embodiment, the first IP address list may include an IP address of the first server, so that the terminal may determine the first IP address list through the IP address of the first server after receiving the notification message.
In another embodiment, 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 the terminal may determine the first IP address list according to the first domain name after receiving the notification message.
S305, the terminal obtains a domain name resolution result from a domain name resolution server based on the notification message; the domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
The domain name resolution result at least comprises a second IP address list. The second list of IP addresses may or may not include the IP address of the first server.
In the embodiment of the 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 the first IP address list is updated from the domain name resolution server, so that the terminal can obtain the second IP address list in time, and the access success rate of the terminal can be improved.
Fig. 4 is a schematic implementation flow chart of another method for updating an IP address according to an embodiment of the present application, as shown in fig. 4, where 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 for indicating the first IP address list to be updated, and is used for the terminal to acquire a second IP address list obtained after the first IP address list is updated from the domain name resolution server.
In an embodiment, 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 the 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 embodiment, the notification message may include the first domain name, so that the terminal may parse the notification message to obtain the first domain name.
In one embodiment, the domain name resolution server may generate a notification message upon determining that an update to the first list of IP addresses has occurred and send the notification message to the gateway. The first IP address list update may be: adding an IP address to the first list of IP addresses, reducing an IP address in the first list of IP addresses, or changing an IP address in the first list of IP addresses.
In an example process, the first IP address list may include M IP addresses, where each of the M IP addresses corresponds to one service server, and the domain name resolution server may receive a change message of an IP address in the first IP address list sent by any one of the M service servers that corresponds to the M IP addresses one-to-one through the gateway, so that the domain name resolution server updates the first IP address list based on the change message. Wherein M is an integer greater than or equal to 1. In another implementation, the domain name resolution server may receive a change message of the IP address sent by the other device, and update the first list of IP addresses based on the change message.
In another example, the second IP address list may include N IP addresses, where each 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 a first access request sent by the terminal.
The embodiment of the application does not limit the sequence of receiving the notification message and the first access request by the gateway.
S405, the gateway sends a notification message and a first access result to the terminal; and the terminal receives the notification message and the first access result sent by the gateway.
It should be understood that the gateway receives the notification message and, after receiving the first access request sent by the terminal, sends the notification message and the first access result to the terminal. The first access result corresponds to the first access request.
S407, the terminal obtains a domain name resolution result from a domain name resolution server based on the notification message; the domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
In the embodiment of the application, through the interaction flow among the terminal, the gateway and the domain name resolution server, the domain name resolution server sends the notification message to the gateway under the condition that the first IP address list is updated, so that the terminal receives the notification message through the gateway and acquires the second IP address list obtained after updating the first IP address list based on the notification message, and further, the terminal can also obtain the updated second IP address list in time after updating the first IP address in the domain name resolution server, and the access success rate of the terminal can be improved.
Fig. 5 is a schematic implementation flow chart of another method for updating an IP address according to an embodiment of the present application, as shown in fig. 5, where the method includes:
s501, the domain name resolution server sends a notification message to the gateway.
The notification message is used for indicating the first IP address list to be updated, and is used for acquiring a second IP address list obtained after the first IP address list is updated from the domain name resolution server after the terminal receives 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 protocol.
The SDK of the terminal may store therein a mapping between each of the plurality of domain names and each of the list of IP addresses. The terminal may determine the first domain name to be accessed based on the operation of the user on the terminal, so as to determine a first IP address list corresponding to the first domain name in the multiple maps. For example, in the case where the first domain name is www.baidu.com, the terminal may determine an IP address list corresponding to the domain name www.baidu.com from among a plurality of maps stored in the SDK so that access can be made based on one of the obtained IP addresses in the IP address list corresponding to www.baidu.com.
In this embodiment of the present application, in the first IP address list, the first IP address list may include not only at least one IP address, but also at least one weight parameter corresponding to the at least one IP address one-to-one, and the terminal may determine the first accessed IP address based on the at least one weight parameter, and if access based on the first accessed IP address fails, determine the second accessed IP address based on the at least one weight parameter until access is successful. The terminal may randomly select one of the at least one IP address as the connection based on a weight random algorithm or a random weight 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 a first access request sent by the terminal.
The first IP address list may include: m IP addresses and M weight parameters corresponding to the M IP addresses one by one, wherein M is an integer greater than or equal to 1; the terminal may determine an IP address of the first server from the M IP addresses based on the M weight parameters, and may further send a first access request to the gateway based on the IP address of the first server.
After the gateway receives the first access request, it may 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. The gateway may then forward the first access request to the first server, which, after receiving the first access request, responds to the first access request and determines a first access result based on the first access request, and then sends the first access result to the gateway.
S507, the gateway sends a notification message and a first access result to the terminal; and the terminal receives the notification message and the first access result sent by the gateway.
S509, the terminal determines a first domain name corresponding to the first IP address list based on the notification message.
The terminal may trigger a flow of determining a domain name corresponding to the IP address of the first server after receiving the notification message. In one embodiment, the terminal may determine the first domain name corresponding to the IP address of the first server based on a 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 a domain name resolution server; the domain name resolution request includes a first domain name; and the domain name resolution server receives the domain name resolution request sent by the terminal.
The communication protocol between the terminal and the domain name resolution server is HTTP. HTTP is one of the most widely used network transport protocols over the internet, and all WWW files adhere to this standard. With the rapid development of internet technology, network services are an indispensable service in people's life, and currently, internet enterprises generally use domain names to provide services to users.
S513, the domain name resolution server sends a domain name resolution result to the terminal; and the terminal receives the domain name resolution result sent by the domain name resolution server.
The domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
DNS data (e.g., a second IP address list) sent by the domain name resolution server to the terminal is easily falsified by a third party if it is not verified. In order to solve the problem, when the domain name resolution server sends the second IP address list to the terminal, an asymmetric encryption method may be used to encrypt the second IP address list, where the encryption manner may be that the domain name resolution server encrypts the second IP address list with a private key, and the terminal decrypts the encrypted data with a public key, or the encryption manner may be that the domain name resolution server encrypts the second IP address list with a public key, and the terminal decrypts the encrypted data with a private key.
When the domain name resolution server encrypts with the private key, the domain name resolution server may perform hash calculation on the second IP address list to obtain a first hash value; then, encrypting the first hash value by adopting a private key to obtain a first signature; the domain name resolution result may then be determined based on the first signature and the second list of IP addresses, e.g., by encoding the first signature and the second list of IP addresses. Wherein the domain name resolution result may include a first signature and a second list of IP addresses.
And S515, checking the domain name resolution result by the terminal, and updating the first mapping stored in the terminal into the second mapping after the checking is successful.
Wherein the first mapping may comprise: mapping between the domain name and the first list of IP addresses, the second mapping may include: mapping between domain name and second list of IP addresses.
The first map and the second map may both be stored in domain name resolution information or a domain name resolution module of the SDK.
When the terminal decrypts with the public key, the terminal can firstly determine the public key corresponding to the domain name resolution server; then, decrypting the first signature by adopting the public key to obtain a first hash value; then, a hash value of a second IP address list can be calculated to obtain a second hash value; and if the first hash value is the same as the second hash value, determining that the verification of the domain name resolution result is successful.
In one embodiment, the public key corresponding to the domain name resolution server may be stored inside the terminal, from which the terminal may obtain the public key corresponding to the domain name resolution server. In one implementation scenario, the public key may be extracted from a digital certificate stored internally in the terminal. In another embodiment, the public key corresponding to the domain name resolution server may be transmitted to the terminal by the domain name resolution server, the public key may be included in the domain name resolution result, or the domain name resolution server may separately transmit the public key to the terminal. In yet another embodiment, the domain name resolution server may further send a digital certificate to the server, where 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 may access the first domain name based on the second IP address list.
If the second IP address list includes one IP address, the IP address is the IP address of the first server, and the terminal may access with the one IP address in the IP address list. If the second IP address list comprises at least two IP addresses, the terminal can determine a first weight parameter based on at least two weight parameters; and then determining a first IP address to be accessed corresponding to the first weight parameter from at least two IP addresses, and accessing by adopting the first IP address to be accessed.
In one embodiment, the terminal may determine a second weight parameter other than the first weight parameter from at least two weight parameters in case of access failure using the first IP address to be accessed; and then, determining a second IP address to be accessed corresponding to the second weight parameter from the at least two IP addresses, and accessing by adopting the second IP address to be accessed.
In this way, since the terminal modifies the first IP address list stored therein to the second IP address list, the terminal can access through the second IP address list when determining an access request for a domain name next time.
After the terminal updates the first IP address list to the second IP address list, if the gateway in the second IP address list is not notified, the gateway does not know whether the terminal updates the first IP address list. To solve this problem, the method of updating the IP address may further include performing the steps of: the terminal sends an update completion message to the gateway; the gateway receives an update completion message sent by the terminal; the update completion message is used for indicating the terminal to complete updating the stored first IP address list.
The timing of the terminal sending 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 in the terminal to the second mapping.
After receiving the update completion message, the gateway may send a second access result to the terminal after receiving a second access request sent by the terminal based on the IP address of the second server based on the update completion message. After that, the gateway receives again the notification message sent by the domain name resolution server, and after receiving the access request of the terminal, sends the notification message to the terminal.
In the embodiment of the application, through the interaction flow among the terminal, the gateway and the domain name resolution server, as the second IP address list can comprise at least one IP address and at least one weight parameter corresponding to the at least one IP address one by one, the terminal can determine the first accessed IP address from the second IP address list by adopting a weight random algorithm, and the situation that the gateway corresponding to the first IP address generates request aggregation is avoided because the terminal accesses from the first IP address each time in the related art. And the terminal checks the second IP address list sent by the domain name resolution server, so that the condition that the second IP address is falsified by a third party is avoided.
Fig. 6 is a schematic flow chart of a terminal obtaining a second IP address list according to an embodiment of the present application, and as shown in fig. 6, a manner in which the terminal obtains the second IP address list may be implemented by the following steps S601 to S611:
s601, the terminal sends a DNS request to a 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 a domain name resolution request in the above embodiment.
S603, after receiving the DNS request, the http DNS server queries a second list of IP addresses corresponding to the domain name in the DNS request.
As shown in fig. 6, the second IP address list has three IP addresses, with percentages of IP1, IP2, and IP3, and weights (corresponding to the weight parameters of the above embodiment) of the three IP addresses are respectively 0.4, 0.3, and 0.3.
S605, the HTTPDNS server may encrypt the second IP address list with the private key.
The encryption mode is that the HTTPDNS server calculates a hash value of the second IP address list to obtain a first hash value, and encrypts the first hash value to obtain a first signature.
S607, the HTTPDNS server may return the result of the DNS request to the terminal.
The returned result may be a domain name resolution result, including the first signature and the second list of IP addresses.
S609, the terminal adopts the public key to decrypt and verify.
The decryption and verification modes are as follows: determining a public key corresponding to the domain name resolution server; decrypting the first signature by adopting the public key to obtain a first hash value; calculating a hash value of the updated IP address list to obtain a second hash value; and if the first hash value is the same as the second hash value, determining that the verification of the domain name resolution result is successful.
The HTTPDNS server may issue a public key, or may issue a certificate for the HTTPDNS server, so that the terminal obtains the public key through the certificate.
S611, the terminal updates the first IP address list to a second IP address list.
After the verification is successful, the terminal may determine that the second IP address list is sent by the domain name resolution server, and then the terminal may update the first IP address list to the second IP address list. The updating process of the terminal may be to delete the first IP address list and write in the second IP address list.
In the embodiment of the application, asymmetric encryption is carried out aiming at the request return result, so that the security of the data content in the network transmission process is effectively ensured, and the content cannot be tampered; and simultaneously, the service is provided to a legally authorized terminal in the form of issuing a certificate and a decryption Token (Token) (which can be understood as a public key), so that irrelevant parties or malicious users are prevented from using the service. This direct Token down approach also avoids the performance loss associated with multiple handshakes using the transport layer security protocol (Transport Layer Security, TLS) connections.

The IP address list BBB includes therein an IP address BBB. The notification message is used to indicate that the IP address list AAA has changed.
S709, the gateway sends the access result and the notification message to the terminal.
The notification message is used to notify the terminal of the change in the IP address list AAA.
S711, the terminal may update the internally stored IP address list AAA to the IP address list BBB after obtaining the IP address list BBB based on the notification message.
After this, the terminal can access the traffic server B based on the address BBB in the IP address list BBB.
In the embodiment of the application, when the IP address configuration is changed, the gateway protocol informs the user that the IP address has been modified. After receiving the message sent by the gateway, the user (terminal) sends out a Dns request in real time to refresh the IP address of the corresponding domain name, thereby achieving the capability of real-time refreshing.
In the embodiment of the application, based on the HTTPDNS service, a set of technical schemes with weights capable of refreshing IP addresses in real time and preventing hijacking is provided, so that the problems of a plurality of pain points such as request aggregation, content tampering, terminal cache and the like faced by the traditional HTTPDNS are solved, and the safety, usability and flexibility of the HTTPDNS are greatly improved.
