Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The Domain Name System (DNS) is a core service of the internet, and serves as a distributed database that maps Domain names and IP addresses to each other, so that a person can access the internet more conveniently without remembering the IP address number string that can be directly read by a machine. Wikipedia, org is a domain name, for example, and corresponds to IP address 208.80.152.2. The DNS is like an automatic telephone directory and we can dial wikipedia's name directly instead of a telephone number (IP address). After we call the website's name directly, the DNS will translate the name (e.g., www.wikipedia.org) that is convenient for the user to use into an IP address (e.g., 208.80.152.2) that is convenient for the machine to recognize.

As shown in fig. 1, when a user inputs or selects www.wikipedia.org as a target domain name in a client of the electronic device 100 shown in fig. 1, the electronic device 100 sends www.wikipedia.org to the domain name server 200, the domain name server 200 parses www.wikipedia.org to obtain a corresponding IP address, then returns the IP address obtained by parsing to the electronic device 100, and then the electronic device 100 sends a network service request to the server 300 to which the IP address points. The client may be an application having a network communication function, and may be, for example, a browser, instant chat software, video software, or the like.

The inventor finds that domain name hijacking and other problems may occur in the process of domain name resolution based on the DNS, which causes that domain name resolution cannot be performed normally. Moreover, if the domain name is sent to the DNS server for domain name resolution each time a network service request needs to be made to the network or a designated server, the efficiency of integrating the network service request may be reduced.

Therefore, the inventor proposes a domain name processing method, a domain name processing device, an electronic device and a storage medium, wherein the domain name required for the network service request is acquired, and then the locally stored history is directly used for performing the service request based on the IP address corresponding to the domain name obtained by the http dns resolution, so as to avoid the domain name hijacking problem caused by the direct domain name resolution and the problem that the service request efficiency is affected by the domain name resolution failure.

Note that, a client having a foreground interface, such as a browser, chat software, or video software, is running in the electronic device. Components may also be run that do not expose network resources to the user, but rather manage the aforementioned clients. In addition, some components which only run in the background and do not have a user interaction interface can also run in the electronic device, wherein the components can also run as independent application programs or can also run as an SDK plug-in of the client. The domain name processing method provided in the embodiment of the present application may be executed in the foregoing client or in the foregoing component, and for the specific operation manner thereof, a description believed by the following embodiment will be provided.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 2, a domain name processing method provided in the embodiment of the present application is applied to a client, and the method includes:

step S110: when the network service request is detected to be required, the domain name required by the network service request is obtained.

The network service request may be triggered after the client detects that a domain name is input in a domain name input area of the client, or triggered after the client detects that a displayed hyperlink is touched. For example, if the client detects that a domain name is input in the domain name input area, and then detects that a control for starting searching is triggered, it is determined that a network service request needs to be performed, and the domain name input in the input area is used as the domain name required for performing the network service request.

Com, when the client detects that the text, the picture or the video is touched, and determines that a network service request needs to be performed, and takes the hyperlink corresponding to the touched text, picture or video as a domain name required for performing the network service request. For example, in the control interface of the device a displayed by the client, the text with the content of starting is displayed, and the hyperlink corresponding to the text with the content of starting is the domain name of the server for performing instruction forwarding. It is to be understood that the server performing the instruction forwarding may be understood as a server forwarding the control instructions of the user to the controlled device.

As shown in fig. 3, the client may operate in the control terminal 100, and then the control instruction sent by the client may be transmitted to the server in the cloud 91 by a mobile terminal network (e.g., a 2G/3G/4G/5G network), and then forwarded to the controlled device 99 by the server in the cloud 91 through the router 90 and the gateway 98. In this way, the client can display the control interface of the controlled device 99, and the displayed content in the interface is the server in the cloud 91 pointed to by the domain name configured to start the text.

Step S120: and searching whether an effective IP address corresponding to the domain name is stored or not, wherein the effective IP address is an IP address which is obtained by historical analysis based on an HTTPDNS mode and corresponds to the domain name.

It will be appreciated that a valid IP address is an IP address that the client has determined can successfully make a network service request. As a way, when the client makes a network service request for the first time, no valid IP address is stored locally, and then the client may directly perform domain name resolution based on the http dns manner, so as to obtain a corresponding IP address. Then, after the analyzed IP address is verified to be successful in making a network service request, the analyzed IP address is stored locally as a valid IP address, so that the client can find the valid IP address in the process of executing step S120.

Step S130: and if the effective IP address corresponding to the domain name is found, generating a network service request based on the found effective IP address.

In embodiments of the present application, the client may generate the network service request based on a plurality of protocols. For example, the network service request may be generated based on an http (hypertext Transfer protocol) protocol or an udp (user Datagram protocol) protocol.

Step S140: and if the effective IP address corresponding to the domain name is not found, acquiring the IP address corresponding to the domain name based on a domain name resolution mode.

Step S150: and generating a network service request based on the IP address acquired by the domain name resolution mode.

According to the domain name processing method, when the fact that a network service is required to be requested is detected, a domain name for the network service request is obtained, whether an IP address which is obtained through historical analysis based on an HTTPDNS mode and corresponds to the domain name is stored or not is searched, and if an effective IP address which corresponds to the domain name is found, a network service request is generated based on the found effective IP address. Therefore, by the method, when the network service request is carried out, the service request can be directly carried out by adopting the locally stored IP address, so that the problem of domain name hijacking caused by directly adopting a domain name resolution mode and the problem that the service request efficiency is influenced by domain name resolution failure are avoided.

Referring to fig. 4, a domain name processing method provided in the embodiment of the present application is applied to a client, and the method includes:

step S210: when the network service request is detected to be required, the domain name required by the network service request is obtained.

Step S220: and searching whether the IP address corresponding to the domain name is stored.

Step S221: and if no IP address corresponding to the domain name is found, generating a network service request based on the IP address obtained in the domain name resolution mode.

Step S222: and if the IP address corresponding to the domain name is found, detecting whether the IP address corresponding to the domain name meets specified conditions.

As one mode, the step of searching whether a valid IP address corresponding to the domain name is stored includes:

searching whether an IP address corresponding to the domain name is stored; if the IP address corresponding to the domain name is found, detecting whether the IP address corresponding to the domain name meets specified conditions; if the IP address corresponding to the domain name meets the specified condition, the IP address corresponding to the domain name is judged to be an effective IP address.

Optionally, the specified conditions include: the IP address corresponding to the domain name has no record information of access failure; or the distance between the recording time of the last access failure of the IP address corresponding to the domain name and the current time exceeds a specified time.

Step S230: if the IP address corresponding to the domain name meets the specified condition, the IP address corresponding to the domain name is judged to be an effective IP address.

Step S231: and generating a network service request based on the searched IP address.

Step S232: if the IP address corresponding to the domain name is detected not to meet the specified condition, judging that the IP address corresponding to the domain name is not an effective IP address, and generating a network service request based on the IP address obtained in the domain name resolution mode.

According to the domain name processing method, after the domain name required by the network service request is acquired, the locally stored history can be directly adopted, the IP address corresponding to the domain name is obtained through resolution based on an HTTPDNS mode, and therefore the domain name hijacking problem caused by the direct adoption of the domain name resolution mode and the problem that the service request efficiency is influenced by domain name resolution failure are avoided. In addition, in the process of acquiring the IP address from the local, the validity of the IP address stored locally can be verified firstly through a set rule, so that the success rate and the reliability of the service request are improved.

Referring to fig. 5, a domain name processing method provided in the embodiment of the present application is applied to a client, and the method includes:

step S310: when the network service request is detected to be required, the domain name required by the network service request is obtained.

Step S320: and searching whether an effective IP address corresponding to the domain name is stored in a first storage area.

As a storage manner, the first storage area may store the domain name and the IP address corresponding to the domain name by using an association data table. For example, as shown in the following table:

operator	IP	Domain name
Move	192.168.0.1	Abcd.com
Telecommunications	192.168.0.2	Dasd.com
Are communicated	192.168.0.3	Qwer.com
ssid	192.168.0.4	Dasde.com

In the above data table, the field operator characterizes the network operator for the IP address adaptation.

As one way, the client may use an IP address that meets a specified condition as an effective IP address corresponding to the domain name. It is understood that the valid IP address determined by the client is an IP address at which the network service request can be successfully made, and then as a way, the client may record the success of the network service request made to the IP address of the first storage area. Taking the example of generating the network service request based on the http protocol, after the client generates and sends the network service request based on the http protocol, if response data based on the http protocol is returned, the client can identify the value of the status field of the http response header in the response data, and if the value of the status field is 200, the client represents that the network service request is successfully performed; if the value of the status field is 400, which indicates that only an error code is returned or the client does not receive http-based response data after a specified time, it is determined that the network service request is not successfully made.

Then in this manner, optionally, the specified conditions include: the IP address corresponding to the domain name has no record information of access failure; or the distance between the recording time of the last access failure of the IP address corresponding to the domain name and the current time exceeds a specified time. It should be noted that the IP address of the server may be changed due to the replacement of the network operator or the dynamic IP address of the IP address, and if the domain name resolution system is not updated immediately, the resolved IP address is an old IP address, and thus the network service cannot be requested successfully. Optionally, the server configured to forward the control instruction is configured with a plurality of IP addresses, which take effect in different time periods, so that the IP addresses of the server may change dynamically according to the time periods, thereby increasing the capability of the server against network attacks.

For example, as a dynamic IP address configuration manner, the server for controlling the forwarding of the command is configured with four IP addresses 192.168.0.2, 192.168.0.3, 192.168.0.4, and 192.168.0.5, it is understood that the four IPs are all mapped to the same domain name, such as abcd. And the configurations 192.168.0.2, 192.168.0.3, 192.168.0.4 and 192.168.0.5 are respectively effective in time periods that are evenly divided within 24 hours of the day, wherein 192.168.0.2 is effective at 0 to 6, 192.168.0.3 is effective at 6 to 12, 192.168.0.4 is effective at 12 to 18, and 192.168.0.5 is effective at 18 to 24 (i.e., 0), it is understood that the server needs to be controlled to complete the requested network service using the effective IP address for different time periods. For example, when a control terminal operated by a user at 9 o' clock sends a network service request for controlling a controlled device to the server configured with a plurality of IPs, the destination IP address of the network service request needs to be 192.168.0.3 in order to send the request to the server.

In one approach, after the client unsuccessfully makes a network service request based on the IP address stored in the first storage area, it may be determined that the IP address is not a valid IP address. In another mode, it can be understood that if the server to which the domain name is directed uses a dynamic IP address, it may perform IP address switching within a certain time period, or reallocate a new IP address each time it is started, and a certain IP address may not successfully perform a network service request, but may perform a network service request after a certain time.

Based on the above manner, the client may first determine whether the IP address corresponding to the server of the requested network service is a fixed IP address or a dynamic IP address, if the fixed IP address is adopted, the client may determine the specified condition as only including the record information that the IP address corresponding to the domain name has no access failure, and if the IP address corresponding to the server of the requested network service is a dynamic IP address, determine the specified condition as only including that the record time of the last access failure of the IP address corresponding to the domain name exceeds a specified duration from the current time. The specified duration may be a duration of one period in which the IP address of the server is dynamically updated.

As a mode, the client and the server for the client to perform the network service request are provided by the same developer, so that the domain name of the server and the configuration mode of the IP address corresponding to the domain name can be stored in the client, and the client can know whether the server is the fixed IP address or the dynamic IP address by identifying the configuration mode.

Step S330: and if the effective IP address corresponding to the domain name is found, generating a network service request based on the found effective IP address.

Step S340: if the effective IP address corresponding to the domain name is not found, whether the IP address to be selected corresponding to the domain name is stored or not is found in a second storage area, wherein the second storage area is different from the first storage area.

It should be noted that, in this embodiment of the application, the IP address stored in the second storage area and corresponding to the domain name is an IP address to be selected that has not been screened yet, and the IP address selected from the IP addresses to be selected in the second storage area is stored in the first storage area, so that the IP address stored in the first storage area is more suitable for the client, and in this manner, the client preferentially searches the IP address stored in the first storage area, and searches the first storage area again when the IP address stored in the first storage area is invalid or when the IP address corresponding to the domain name required by the network service request is not found.

Similarly, in the second storage area, the domain name and the IP address may be stored correspondingly in a manner of associating the data table. For example, as shown in the following table:

the data table in the second storage area has more fields than the data table in the first storage area storing the IP address. For example, the "valid timestamp" field is used to store a valid time period corresponding to the IP address, the "port" field is used to store an access port adapted to the IP address, and the "weight" field is used to store a recommendation degree for the IP address to be used, where the higher the weight is, the higher the recommendation degree is. It should be noted that, for the "valid timestamp" field, in order to facilitate data storage, the client may perform feature value calculation (for example, hash calculation) on the start time and the end time represented by the valid time period, and then store the calculated feature value into the "valid timestamp" field, and when the valid time period needs to be queried, perform reverse calculation on the data.

As a mode, the step of searching whether the to-be-selected IP address corresponding to the domain name is stored in the second storage area includes: searching whether an IP address corresponding to the domain name exists in an appointed file (for example, the data table) in a second storage area, if the IP address corresponding to the domain name exists in the appointed file, detecting whether the IP address corresponding to the domain name in the appointed file meets an effective condition, and if the IP address meets the effective condition, taking the IP address meeting the effective condition as a to-be-selected IP address. Wherein the effective conditions include at least one of the following conditions: the current moment is in an effective timestamp corresponding to the IP address; and the access success rate corresponding to the IP address is higher than a specified value. The current time can be understood to be between the start time and the end time of the valid time period in the valid timestamp corresponding to the IP address.

As another mode, the second storage area further stores first network characteristic information corresponding to each IP address to be selected, and the step of determining a target IP address from the IP addresses to be selected includes: acquiring second network characteristic information of a network accessed by a client; and taking the IP address matched with the first network characteristic information and the second network characteristic information in the IP addresses to be selected as a target IP address, and further generating a network service request based on the target IP address. It will be appreciated that data transfer between devices provided by the same network operator is generally more efficient than data transfer across carrier operators. In this way, the client can use the IP address stored in the second storage area and also adapted to the mobile (operator name) when recognizing that the network to which the client has access is a mobile network, so as to improve the service request efficiency. Then, based on the above, the first network characteristic information may comprise an adapted network operator and the second network characteristic information comprises an adapted network operator. In this case, the step of using the IP address with the corresponding first network characteristic information and the second network characteristic information in the candidate IP address as the target IP address includes: and taking the IP address which is matched with the network operator in the IP addresses to be selected and is the same as the network operator of the network accessed by the client as a target IP address.

As another mode, the second storage area further stores a weight corresponding to each to-be-selected IP address; the step of using the IP address, which is the same as the network operator of the network to which the client accesses, of the network operator adapted to the IP address to be selected as the target IP address includes: acquiring the number of reference IP addresses, wherein the reference IP addresses are the same IP addresses of the network operator adapted to the IP address to be selected and the network operator of the network accessed by the client; if the number is larger than 1, comparing the respective corresponding weights of the reference IP addresses; and taking the reference IP address with the maximum corresponding weight as the target IP address.

Step S350: and if the IP address to be selected is found, determining a target IP address from the IP address to be selected, and generating a network service request based on the target IP address.

Step S360: and correspondingly storing the target IP address and the domain name into the first storage area.

Step S370: and if the IP address to be selected is not found, generating a network service request based on the IP address acquired in the domain name resolution mode.

According to the domain name processing method, after the domain name required by the network service request is acquired, the locally stored history can be directly adopted, the IP address corresponding to the domain name is obtained through resolution based on an HTTPDNS mode, and therefore the domain name hijacking problem caused by the direct adoption of the domain name resolution mode and the problem that the service request efficiency is influenced by domain name resolution failure are avoided. In addition, in this embodiment, the IP address obtained by analyzing based on the http dns method through the multi-level cache history may be used, so that the directly usable IP address that has been determined by calculation may be first searched in the first storage area, and if no valid IP address is found in the first storage area, the IP address that has not been determined by calculation may be searched in the second storage area, and after the IP address corresponding to the domain name is found in the second storage area, an IP address that is most matched with the current client may be selected by calculation to generate the network service request, thereby further improving the stability and reliability in the process of converting the domain name into the IP address.

Referring to fig. 6, a domain name processing method provided in the embodiment of the present application is applied to a client, and the method includes:

step S410: when the network service request is detected to be required, the domain name required by the network service request is obtained.

Step S420: and searching whether an effective IP address corresponding to the domain name is stored or not, wherein the effective IP address is an IP address which is obtained by historical analysis based on an HTTPDNS mode and corresponds to the domain name.

Step S430: and if the effective IP address corresponding to the domain name is found, generating a network service request based on the found effective IP address.

Step S440: and if the IP address to be selected is not found, sending a first domain name resolution request carrying the domain name to a DNS (domain name server), and simultaneously sending a second domain name resolution request carrying the domain name to a specified HTTPDNS server.

Step S450: and determining an IP address corresponding to the domain name based on respective response results of the first domain name resolution request and the second domain name resolution request.

As one mode, the step of determining an IP address corresponding to the domain name based on the response result of each of the first domain name resolution request and the second domain name resolution request includes:

if the response result of the first domain name resolution request is detected to be received first, acquiring an IP address from the response result of the first domain name resolution request as the IP address corresponding to the domain name;

and if the detection is that the response result of the second domain name resolution request is received first, acquiring an IP address from the response result of the second domain name resolution request as the IP address corresponding to the domain name.

Furthermore, the step of obtaining an IP address from the response result of the first domain name resolution request as the IP address corresponding to the domain name if it is detected that the response result of the first domain name resolution request is received first further includes:

and if a response result of the second domain name resolution request is received, acquiring an IP address from the response result of the second domain name resolution request, storing the IP address into the second storage area, and covering the IP address to be selected corresponding to the domain name in the second storage area. As a mode, in order to further improve the reliability of the response result of the second domain name resolution request, after the response result of the second domain name resolution request is received, validity verification may be performed first, and then storage may be performed after the verification is passed. It should be noted that the HTTP dns server may perform encryption signing on the response message returned to the client by using the HmacSHA256 signature algorithm, obtain a corresponding signature array, encode the signature array by using Base64 to obtain a character string, and set the character string in the HTTP Header of the response result. And after receiving the response result, the client uses the same algorithm for the received response result to obtain a character string, compares the character string with the character string in the HTTP Header, and if the character string is the same, the verification is passed.

It should be noted that, in the process of performing domain name resolution in the conventional DNS manner, a risk of domain name hijacking may occur, so that a required IP address cannot be successfully returned, or a risk of a falsification of a returned IP address exists. As a mode, if the client receives the response result of the second domain name resolution request first when the client sends the first domain name resolution request and the second domain name resolution request simultaneously based on an asynchronous mode, the client may generate the network service request based on the IP address in the response result of the second domain name resolution request first, and then perform the operation of verifying and storing the response result.

As one mode, before executing step S440, the method further includes: and acquiring the time-efficiency requirement of the service which needs to carry out the network service request. Optionally, the step of obtaining the aging requirement of the service requiring the network service request includes: if the service is identified as equipment control, judging that the timeliness requirement of the service for equipment control is a first timeliness requirement; and if the service is identified as equipment configuration, judging that the timeliness requirement of the service controlled by the equipment is a second timeliness requirement.

If the time efficiency requirement meets a first time efficiency requirement, sending a first domain name resolution request carrying the domain name to a DNS (domain name server), and determining an IP (Internet protocol) address corresponding to the domain name based on a response result of the first domain name resolution request; if the timeliness meets a second timeliness requirement, the step S440 is executed, where the timeliness corresponding to the first timeliness requirement is higher than the timeliness corresponding to the second timeliness requirement.

According to the domain name processing method, after the domain name required by the network service request is acquired, the locally stored history can be directly adopted, the IP address corresponding to the domain name is obtained through resolution based on an HTTPDNS mode, and therefore the domain name hijacking problem caused by the direct adoption of the domain name resolution mode and the problem that the service request efficiency is influenced by domain name resolution failure are avoided. And when the IP address to be selected is detected not to be found, the domain name resolution can be carried out based on a DNS mode and an HTTPDNS mode, so that the success rate and the reliability of the domain name resolution are further ensured, and the success rate of the network service request is also improved. Furthermore, the destination IP address as the network service request may be determined according to the sequence of sending the first domain name resolution request carrying the domain name to the DNS server and sending the response of the second domain name resolution request carrying the domain name to the specified http DNS server.

Referring to fig. 7, a domain name processing method provided in an embodiment of the present application is applied to a component having a function of communicating with a client, and the method includes:

step S510: when the client is detected to need to carry out the network service request, the domain name required by the network service request is obtained.
