Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The domain name system (DNS, domain Name System, sometimes simply referred to as a domain name) is a core service of the internet, which serves as a distributed database that maps domain names and IP addresses to each other, enabling people to more conveniently access the internet without having to remember a string of IP addresses that can be read directly by a machine. For example, www.wikipedia.org is a domain name corresponding to IP address 208.80.152.2. DNS is just like an automatic telephone directory, and we can dial the name of wikipedia directly instead of the telephone number (IP address). After we call directly on the name of the website, DNS will translate the name (e.g., www.wikipedia.org) that is convenient for the user to an IP address (e.g., 208.80.152.2) that is convenient for machine identification.
As shown in fig. 1, when a user inputs or selects www.wikipedia.org as a target domain name in a client in 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, and returns the parsed IP address 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 program with a network communication function, for example, a browser, instant chat software, video software, or the like.
The inventors found in the study that in the process of performing domain name resolution based on DNS, the problem of domain name hijacking may occur, which results in that domain name resolution cannot be performed normally. And if the network service request needs to be sent to the network or the designated server every time, the domain name is sent to the DNS server for domain name resolution, which reduces the efficiency of integrating the network service request.
Therefore, when a network service request is made, the inventor provides a domain name processing method, a device, an electronic device and a storage medium for directly adopting a locally stored history to make a service request based on an IP address corresponding to the domain name obtained by HTTPDNS mode analysis after obtaining the domain name required for making the network service request, so as to avoid the domain name hijacking problem caused by directly adopting the domain name analysis mode and the problem that the domain name analysis failure affects the service request efficiency.
In addition, a client having a foreground interface, such as a browser, even chat software, video software, or the like, is running in the electronic device. Some 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 be run in the electronic device, wherein the components can also run in independent application programs and can also run as an SDK plug-in of the client. The domain name processing method provided by the embodiment of the present application may be executed on the foregoing client or on the foregoing component, and for the specific operation mode thereof, the following description will be believed to be provided by the following embodiment.
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 by an embodiment of the present application is applied to a client, and the method includes:
step S110: and when detecting that the network service request needs to be carried out, acquiring a domain name required by the network service request.
The network service request may be triggered after the client detects that a domain name is input in a domain name input area in the client, or may be 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 the control for starting searching is triggered, it determines that a network service request needs to be performed, and takes the domain name input in the input area as the domain name required for performing the network service request.
For another example, a text, a picture or a video configured with a hyperlink is displayed in an interface of the client, for example, when the hyperlink corresponding to the text, the picture or the video is oppo.com, after 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 the hyperlink corresponding to the touched text, the picture or the video is used as a domain name required for performing the network service request. For example, in the control interface of the device a displayed on the client, the text whose content is the start-up text is displayed, and then the text whose content is the start-up text is correspondingly configured with a hyperlink as a domain name of the server for instruction forwarding. It is understood that the server performing the instruction forwarding may be understood as a server forwarding the control instruction 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 by the mobile terminal network (e.g. 2G/3G/4G/5G network) to the server in the cloud 91, and then forwarded by the server in the cloud 91 to the controlled device 99 through the router 90 and the gateway 98. In this manner, the client may display a control interface of the controlled device 99 in which the domain name configured to initiate this text is directed to the server in the cloud 91.
Step S120: searching whether an effective IP address corresponding to the domain name is stored or not, wherein the effective IP address is an IP address corresponding to the domain name, which is obtained through historical resolution based on an HTTPDNS mode.
It can be appreciated that the valid IP address is the IP address determined by the client that can successfully make the network service request. As a way, when the client makes a network service request for the first time, a valid IP address is not stored locally, and then the client may directly perform domain name resolution based on the http dns way, so as to obtain a corresponding IP address. And then after verifying that the resolved IP address can successfully perform the network service request, storing the resolved IP address as an effective IP address locally, so that the client can find out 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, a client may generate a web service request based on a variety of protocols. For example, the network service request may be generated based on the http (HyperText Transfer Protocol) protocol or the udp (User Datagram Protocol) protocol.
Step S140: 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.
The domain name processing method provided by the application comprises the steps of acquiring a domain name for requesting network service when detecting that network service is required, searching whether an IP address corresponding to the domain name, which is obtained through historical resolution based on an HTTPDNS mode, is stored, and generating the network service request based on the searched effective IP address if the effective IP address corresponding to the domain name is found. Therefore, when the network service request is carried out, the local stored IP address can be directly adopted to carry out the service request, so that the domain name hijacking problem caused by directly adopting a domain name resolution mode and the problem that the domain name resolution failure affects the service request efficiency are avoided.
Referring to fig. 4, a domain name processing method provided by an embodiment of the present application is applied to a client, and the method includes:
step S210: and when detecting that the network service request needs to be carried out, acquiring a domain name required by the network service request.
Step S220: and searching whether the IP address corresponding to the domain name is stored.
Step S221: if no IP address corresponding to the domain name is found, generating a network service request based on the IP address acquired by the domain name resolution mode.
Step S222: if the IP address corresponding to the domain name is found, detecting whether the IP address corresponding to the domain name meets the specified condition.
As one way, 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 or not; if the IP address corresponding to the domain name is found, detecting whether the IP address corresponding to the domain name meets the specified condition; and if the IP address corresponding to the domain name is detected to meet the specified condition, judging that the IP address corresponding to the domain name is a valid IP address.
Optionally, the specified condition includes: the IP address corresponding to the domain name has no record information of access failure; or the recording time of the last access failure of the IP address corresponding to the domain name exceeds the current time for a specified duration.
Step S230: and if the IP address corresponding to the domain name is detected to meet the specified condition, judging that the IP address corresponding to the domain name is a valid 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 does not meet the specified condition, judging that the IP address corresponding to the domain name is not a valid IP address, and generating a network service request based on the IP address acquired by the domain name resolution mode.
The domain name processing method provided by the application can directly adopt the locally stored history to analyze the service request based on the IP address corresponding to the domain name in the HTTPDNS mode after obtaining the domain name required by the network service request, thereby avoiding the domain name hijacking problem caused by directly adopting the domain name analysis mode and the problem that the domain name analysis failure influences the service request efficiency. In addition, in the process of acquiring the IP address from the local, the validity of the locally stored IP address can be verified 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 by an embodiment of the present application is applied to a client, and the method includes:
step S310: and when detecting that the network service request needs to be carried out, acquiring a domain name required by the network service request.
Step S320: and searching whether a valid IP address corresponding to the domain name is stored in the 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 using an association data table. For example, as shown in the following table:
| operators (operators) | IP | Domain name |
| Movement of | 192.168.0.1 | Abcd.com |
| Telecommunication | 192.168.0.2 | Dasd.com |
| Communication with each other | 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 IP address adaptation.
In one manner, the client may use the IP address satisfying the specified condition as the valid IP address corresponding to the domain name. It may be appreciated that, if the valid IP address determined by the client is an IP address that can successfully perform the network service request, then, as a way, the client may record the success of performing the network service request on the IP address of the first storage area. Taking generating a network service request based on an http protocol as an example, after generating and sending the network service request based on the http protocol, if the response data based on the http protocol is returned, the client can identify the value of a status field of an http response header in the response data, and if the value of the status field is 200, the client characterizes 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 that the client does not receive response data based on the http protocol after a specified time, it is determined that the network service request is not successfully performed.
In this way, then, optionally, the specified conditions include: the IP address corresponding to the domain name has no record information of access failure; or the recording time of the last access failure of the IP address corresponding to the domain name exceeds the current time for a specified duration. It should be noted that, the IP address of the server may be changed by changing the network operator or using the IP as the dynamic IP address, and if the domain name resolution system is not updated immediately, the resolved IP address is the old IP address, which results in a failure to request the network service successfully. Optionally, the server for forwarding the control instruction is configured with a plurality of IP addresses that are respectively valid in different time periods, so that the IP address of the server can be dynamically changed according to the time periods, and the capability of the server for resisting network attacks is increased.
For example, as a dynamic IP address configuration manner, the server for forwarding the control instruction 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 these four IPs are all mapped to the same domain name such as abcd. And configurations 192.168.0.2, 192.168.0.3, 192.168.0.4 and 192.168.0.5 are each validated during a time period equally divided during 24 hours of the day, wherein 192.168.0.2 is validated at point 0 to point 6, 192.168.0.3 is validated at point 6 to point 12, 192.168.0.4 is validated at point 12 to point 18, 192.168.0.5 is validated at point 18 to point 24 (i.e., point 0), it being understood that validated IP addresses need to be employed for different time periods to control the server to complete the requested network service. For example, when a control terminal operated by a user transmits a network service request for controlling a controlled device to the server configured with a plurality of IPs at 9 points, the destination IP address of the network service request needs to be 192.168.0.3 in order to transmit the request to the server.
In one manner, after the client does not successfully make the 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 manner, it can be appreciated that if a dynamic IP address is used for the server to which the domain name points, it is possible to switch IP addresses within a certain period of time, or to reassign a new IP address each time it is started, and then it occurs that although a certain IP address cannot successfully make a network service request, a network service request can be made after a certain period of time.
Then, based on the above manner, the client may determine whether the IP address corresponding to the server of the requested network service is a fixed IP address or a dynamic IP address, and if the fixed IP address is adopted, the client may determine that the foregoing specified condition includes only 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 that the foregoing specified condition includes only the record time of the last access failure of the IP address corresponding to the domain name exceeds the current time by a specified duration. The specified duration may be a duration of one period of IP address dynamic update of the IP of the server.
In one mode, the client and the server for the network service request are provided by the same developer, so that the client can store the domain name of the server and the configuration mode of the IP address corresponding to the domain name, and the client can know whether the server adopts 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, searching whether the candidate IP address corresponding to the domain name is stored in a second storage area, wherein the second storage area is different from the first storage area.
In this way, the client can search the IP address stored in the first storage area preferentially, and search 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 for requesting the network service is not found.
Similarly, in the second storage area, the domain name and the IP address may be stored correspondingly in the form of an associated 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 storing the IP address in the first storage area. For example, the "effective timestamp" field is used to store an effective period of time corresponding to the IP address, the "port" field is used to store an access port to which the IP address is adapted, and the "weight" field is used to store a recommendation level to which the IP address is adapted, where the higher the weight, the higher the recommendation level. For the "effective timestamp" field, in order to facilitate data storage, the client may perform the feature value calculation (for example, hash calculation) on the start time and the end time represented by the effective time period, then store the calculated feature value in the "effective timestamp" field, and when the effective time period needs to be queried, perform the reverse calculation on the data.
As one way, the step of searching whether the candidate IP address corresponding to the domain name is stored in the second storage area includes: searching whether the IP address corresponding to the domain name exists in a designated file (for example, the data table) of the second storage area, if so, detecting whether the IP address corresponding to the domain name exists in the designated file and meets the effective condition, and if so, taking the IP address meeting the effective condition as a candidate IP address. Wherein the effective conditions include at least one of the following conditions: the current moment is in the effective time stamp corresponding to the IP address; and the access success rate corresponding to the IP address is higher than the appointed value. The current time is understood to be between the start time and the end time of the effective time period in the effective time stamp corresponding to the IP address.
Alternatively, the second storage area further stores first network feature information corresponding to each IP address to be selected, and the step of determining the target IP address from the IP addresses to be selected includes: acquiring second network characteristic information of a network accessed by the client; and taking the IP address matched with the first network characteristic information and the second network characteristic information corresponding to the IP address 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 the efficiency of data transfer between devices provided by the same network operator is generally higher than the efficiency of data transfer across operators. In this way, the client can use the IP address stored in the second storage area that is also adapted to the mobile when identifying that the network to which the client has access is a mobile (carrier name) 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 matching the corresponding first network characteristic information of the candidate IP addresses with the second network characteristic information as the target IP address includes: and taking the IP address, which is the same as the network operator of the network accessed by the client, of the network operators adapted in the IP address to be selected as a target IP address.
As a further way, the second storage area further stores a weight corresponding to each IP address to be selected; the step of using the same IP address of the network operator adapted in the candidate IP address as the network operator of the network accessed by the client 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 operators matched in the IP addresses to be selected and the network operators of the network accessed by the client; if the number is identified to be greater than 1, comparing the weights corresponding to the reference IP addresses; and taking the reference IP address with the largest corresponding weight as the target IP address.
Step S350: if the IP address to be selected is found, determining a target IP address from the IP addresses to be selected, and generating a network service request based on the target IP address.
Step S360: and storing the target IP address and the domain name in the first storage area correspondingly.
Step S370: and if the candidate IP address is not found, generating a network service request based on the IP address acquired by the domain name resolution mode.
The domain name processing method provided by the application can directly adopt the locally stored history to analyze the service request based on the IP address corresponding to the domain name in the HTTPDNS mode after obtaining the domain name required by the network service request, thereby avoiding the domain name hijacking problem caused by directly adopting the domain name analysis mode and the problem that the domain name analysis failure influences the service request efficiency. In this embodiment, the IP address obtained by resolving the multi-level cache history based on the http dns method may be searched in the first storage area, if no valid IP address is found in the first storage area, the IP address found in the second storage area may be found, and after the IP address corresponding to the domain name is found in the second storage area, one IP address that is most matched with the current client may be selected by calculation to generate a network service request, thereby further improving stability and reliability in the domain name-to-IP address conversion process.
Referring to fig. 6, a domain name processing method provided by an embodiment of the present application is applied to a client, and the method includes:
step S410: and when detecting that the network service request needs to be carried out, acquiring a domain name required by the network service request.
Step S420: searching whether an effective IP address corresponding to the domain name is stored or not, wherein the effective IP address is an IP address corresponding to the domain name, which is obtained through historical resolution based on an HTTPDNS mode.
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: if the candidate IP address is not found, a first domain name resolution request carrying the domain name is sent to a DNS server, and a second domain name resolution request carrying the domain name is sent to a designated HTTPDNS server.
Step S450: and determining the IP address corresponding to the domain name based on the response results of the first domain name resolution request and the second domain name resolution request.
In one mode, the step of determining the IP address corresponding to the domain name based on the response results 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 an IP address corresponding to the domain name;
if the response result of the second domain name resolution request is detected to be received, the IP address is obtained from the response result of the second domain name resolution request and is used as the IP address corresponding to the domain name.
And if the step of acquiring the IP address from the response result of the first domain name resolution request as the IP address corresponding to the domain name after detecting that the response result of the first domain name resolution request is received first, the step of acquiring the IP address as the IP address corresponding to the domain name 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 in the second storage area, and covering a candidate IP address corresponding to the domain name in the second storage area. As a way, in order to further improve the reliability of the response result of the second domain name resolution request, after receiving the response result of the second domain name resolution request, validity verification may be first performed, and after the verification is passed, storage may be performed. It should be noted that, the HTTPDNS server may encrypt and sign the response message returned to the client by using the HmacSHA256 signing algorithm, obtain a corresponding signature array, encode the corresponding signature array by using Base64 to obtain a string, and set the string in the HTTP Header of the response result. After receiving the response result, the client uses the same algorithm to 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 authentication is passed.
It should be noted that, in the process of performing domain name resolution in the conventional DNS method, a risk of domain name hijacking occurs, so that a required IP address cannot be successfully returned, or a risk of being altered by a string exists in the returned IP address. If the client side receives the response result of the second domain name resolution request when the client side sends the first domain name resolution request and the second domain name resolution request in an asynchronous mode, the network service request can be generated based on the IP address in the response result of the second domain name resolution request, and then the operation of verifying and storing the response result can be performed.
As one way, before performing step S440, further includes: and acquiring the aging requirement of the service requiring the network service request. Optionally, the step of obtaining the aging requirement of the service needing to make the network service request includes: if the service is identified to be equipment control, judging that the aging requirement of the service for equipment control is a first time requirement; and if the service is identified to be the equipment configuration, judging that the aging requirement of the service for equipment control is a second aging requirement.
If the aging requirement meets the first aging requirement, sending a first domain name resolution request carrying the domain name to a DNS server, and determining an IP address corresponding to the domain name based on a response result of the first domain name resolution request; if the indicated timeliness meets the 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.
The domain name processing method provided by the application can directly adopt the locally stored history to analyze the service request based on the IP address corresponding to the domain name in the HTTPDNS mode after obtaining the domain name required by the network service request, thereby avoiding the domain name hijacking problem caused by directly adopting the domain name analysis mode and the problem that the domain name analysis failure influences the service request efficiency. And when the fact that the IP address to be selected is not found is detected, domain name resolution can be carried out based on a DNS mode and an HTTPDNS mode at the same time, so that the success rate and reliability of the domain name resolution are further guaranteed, and the success rate of the network service request is also improved. Further, the destination IP address as the network service request may be determined according to a sequence in which the first domain name resolution request carrying the domain name is sent to the DNS server, and the response of the specified http DNS server to the second domain name resolution request carrying the domain name is sent.
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: and when the client is detected to be in need of network service request, acquiring a domain name required by the network service request.
As a way, the client can be adaptively changed, so that data interaction can be performed between the client and the component in an inter-process communication way, and further, the component obtains when the client needs to perform a network service request.
