Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In order to resolve a domain name to be resolved, an embodiment of the present invention provides a domain name resolution method, where a server stores a plurality of pieces of domain name information, each piece of domain name information records a domain name to be resolved, and the domain name to be resolved recorded in each piece of domain name information corresponds to an IP address of a different server for operating a target website, where the method includes:
responding to a domain name resolution request sent by a client, and reading each piece of locally stored domain name information;
analyzing the domain name to be analyzed in each read domain name information, and determining an IP address corresponding to each domain name to be analyzed as a domain name analysis result;
and sending each domain name resolution result to the client so that the client accesses the target website based on the domain name resolution result.
As can be seen from the above, after receiving a domain name resolution request sent by a client, a server first reads each piece of domain name information stored locally, where each piece of domain name information records a domain name to be resolved, where the domain name to be resolved corresponds to an IP address of a server for operating a target website and different domain names to be resolved correspond to different IP addresses, and because the server can resolve the domain name to be resolved recorded in each piece of domain name information that is read, it can determine each IP address corresponding to the domain name to be resolved, and for each determined IP address, because the IP address is the IP address of the server for operating the target website, the server can take the IP address as a domain name resolution result and send the domain name resolution result to the client. Therefore, through the scheme of the embodiment of the invention, the domain name can be analyzed, so that the client accesses the target website based on the domain name analysis result, and further can access the information provided by the target website.
In addition, according to the domain name resolution protocol provided in the prior art, only one piece of domain name information is generally stored in the server for domain name resolution, and even if a plurality of pieces of domain name information are stored in the server, in the process of performing domain name resolution on a domain name to be resolved in each piece of domain name information, a domain name resolution result obtained by the subsequent resolution covers a domain name resolution result obtained by the previous resolution, so that only one domain name resolution result can be finally obtained. In the solution provided by the embodiment of the present invention, the execution main body of the present invention is to allow storage of multiple pieces of domain name information, and each piece of domain name information stored locally can be read, and a domain name to be resolved in each piece of domain name information that is read is resolved, and coverage of a domain name resolution result does not occur.
Fig. 1 is a schematic flow chart of a first domain name resolution method provided in an embodiment of the present invention, in which a server stores a plurality of pieces of domain name information, each piece of domain name information records a domain name to be resolved, and the domain name to be resolved recorded in each piece of domain name information corresponds to IP addresses of different servers for operating a target website, as shown in fig. 1, the method may include the following steps: S101-S103.
Step S101: and responding to a domain name resolution request sent by the client, and reading each piece of locally stored domain name information.
Specifically, the server may store a plurality of pieces of domain name information, each piece of domain name information records a domain name to be resolved, each domain name to be resolved is a domain name of the target website, that is, for each domain name to be resolved, an IP address corresponding to the domain name to be resolved may be determined, and the client may access the target website based on the IP address. However, the domain names to be resolved recorded in different domain name information are different, such as: two pieces of domain name information are stored in the server, so that the domain name to be resolved recorded in the first piece of domain name information may be the domain name of a server provided by an M manufacturer, and the domain name to be resolved recorded in the second piece of domain name information may be the domain name of a server provided by an N manufacturer; or the domain name to be resolved recorded in the first piece of domain name information may be a domain name of a server provided by an O manufacturer, and the domain name to be resolved recorded in the second piece of domain name information may be a domain name of a server provided by a P manufacturer, in short, the domain name to be resolved recorded in the first piece of domain name information is different from the domain name to be resolved recorded in the second piece of domain name information.
Next, each domain name to be resolved corresponds to at least one IP address, such as: for each domain name to be resolved, the domain name to be resolved may correspond to only one IP address, or may correspond to a plurality of IP addresses such as two IP addresses and three IP addresses.
In addition, different domain names to be resolved correspond to the IP addresses of different servers for operating the target website respectively. Such as: if the target website that the client wants to access is a website a, and then two domain names are locally stored, one domain name to be resolved may be aaa.mmm.com, that is, the domain name of the server provided by M vendor, and the other domain name to be resolved may be aaa.nnn.com, that is, the domain name of the server provided by N vendor, and the IP address corresponding to the domain name aaa.mmm.com is: the IP address of the server provided by the M manufacturer of the website running A; the IP address corresponding to the domain name aaa.nnn.com is: the IP address of the server provided by N vendor of the website running A.
In an embodiment of the present invention, when a client needs to access the target website, the client may send a domain name resolution request to a server through a User Datagram Protocol (UDP) Protocol, and the server reads each piece of domain name information stored locally after receiving the domain name resolution request, where sending the domain name resolution request to the server through the UDP Protocol is prior art, and a specific implementation manner is not described herein again.
In another embodiment of the present invention, each domain name information records a domain name to be resolved of a CNAME (alias) type, and for each domain name to be resolved of a CNAME type, the domain name to be resolved corresponds to an address (a) record, the address (a) record corresponds to an IP address, and the IP address is the IP address corresponding to the domain name to be resolved.
And S102, resolving the domain name to be resolved in each read domain name information, and determining an IP address corresponding to each domain name to be resolved as a domain name resolution result.
Specifically, because the domain name to be resolved in each domain name information corresponds to at least one IP address, and different IP addresses correspond to different domain names to be resolved, the domain name to be resolved in each domain name information can be resolved, and the IP address corresponding to each domain name to be resolved is determined as a domain name resolution result.
In an embodiment of the present invention, for each piece of Domain Name information that is read, a Domain Name to be resolved recorded in each piece of Domain Name information is simultaneously acquired, and then the acquired Domain Name to be resolved may be resolved based on a conventional DNS (Domain Name System) resolution method.
In another embodiment of the present invention, the step S102 can be implemented by the following step S102A in fig. 3, which will not be described in detail here.
Step S103: and sending each domain name resolution result to the client so that the client accesses the target website based on the domain name resolution result.
Specifically, for each domain name resolution result, the domain name resolution result is an IP address of a server corresponding to an operating destination website, and thus, each domain name resolution result may be sent to the client, so that the client may select an IP address of a server operating a destination website based on each domain name resolution result, and then access the destination website based on the selected IP address. The client may select the IP address based on the prior art, which is not limited in the embodiment of the present invention.
In an embodiment of the present invention, the server may send each domain name resolution result to the client based on a UDP protocol, where sending a domain name resolution request to the server by the client through the UDP protocol is prior art, and a specific implementation manner is not described herein again.
In another embodiment of the present invention, the above steps can be implemented by step S103A in fig. 2, and can also be implemented by step S103B-step S103C in fig. 4, which will not be described in detail here.
As can be seen from the above, after receiving a domain name resolution request sent by a client, a server first reads each piece of domain name information stored locally, where each piece of domain name information records a domain name to be resolved, where the domain name to be resolved corresponds to an IP address of a server for operating a target website and different domain names to be resolved correspond to different IP addresses, and because the server can resolve the domain name to be resolved recorded in each piece of domain name information that is read, it can determine each IP address corresponding to the domain name to be resolved, and for each determined IP address, because the IP address is the IP address of the server for operating the target website, the server can take the IP address as a domain name resolution result and send the domain name resolution result to the client. Therefore, through the scheme of the embodiment of the invention, the domain name can be analyzed, so that the client accesses the target website based on the domain name analysis result, and further can access the information provided by the target website.
In addition, according to the domain name resolution protocol provided in the prior art, only one piece of domain name information is generally stored in the server for domain name resolution, and even if a plurality of pieces of domain name information are stored in the server, in the process of performing domain name resolution on a domain name to be resolved in each piece of domain name information, a domain name resolution result obtained by the subsequent resolution covers a domain name resolution result obtained by the previous resolution, so that only one domain name resolution result can be finally obtained. In the solution provided by the embodiment of the present invention, the execution main body of the present invention is to allow storage of multiple pieces of domain name information, and can read each piece of locally stored domain name information, resolve a domain name to be resolved in each piece of read domain name information, and no coverage of a domain name resolution result occurs.
Fig. 2 is a schematic flow chart of a second domain name resolution method according to an embodiment of the present invention, as shown in fig. 2, compared with the embodiment shown in fig. 1, after the step S102, the method further includes the following steps: s104, the step S103 may include the following steps: S103A.
Step S104: and aiming at each determined IP address, acquiring flow indication information based on preset flow distribution information, and acquiring a domain name resolution result containing the IP address and the flow indication information corresponding to the IP address.
Wherein the traffic allocation information is used to: and allocating the data volume of the flow which can be processed by the server to the server corresponding to each IP address.
Specifically, the traffic allocation information is used to allocate the data volume of the processable traffic to the server corresponding to each IP address, so that the data volume of the processable traffic to the server corresponding to the IP address can be allocated for each IP address based on the preset traffic allocation information, and the data volume of the processable traffic allocated to the server corresponding to each IP address can be used as the traffic indication information.
In an embodiment of the present invention, the traffic distribution information may be preset according to an access speed of the client when accessing information in the target website based on servers corresponding to different IP addresses.
For example: the preset traffic distribution information may be a value, the value range of the value is 0-1, and the sum of the values of the traffic distribution information corresponding to each IP address is equal to 1. If two IP addresses, namely a first IP address and a second IP address, are determined in total, if according to the previous usage of the servers corresponding to the two IP addresses, the access speed when the server corresponding to the first IP address accesses information in the destination website is fast, and the access speed when the server corresponding to the second IP address accesses information in the destination website is slow, the value of the traffic distribution information corresponding to the first IP address may be 0.8, and the value of the traffic distribution information corresponding to the second IP address may be 0.2, that is, the data volume of the traffic that can be processed by the server corresponding to the first IP address accounts for eight tenths of the total data volume that can be processed, and the data volume of the traffic that can be processed by the server corresponding to the second IP address accounts for two tenths of the total data volume that can be processed.
Or, if the server corresponding to the first IP address has a slow access speed when accessing information in the destination website and the server corresponding to the second IP address has a fast access speed when accessing information in the destination website according to the previous usage of the servers corresponding to the two IP addresses, the value of the traffic allocation information corresponding to the first IP address may be 0.4 and the value of the traffic allocation information corresponding to the second IP address may be 0.6, that is, the data amount of the traffic that can be processed by the server corresponding to the first IP address accounts for four tenths of the total data amount that can be processed, and the data amount of the traffic that can be processed by the server corresponding to the second IP address accounts for six tenths of the total data amount that can be processed. That is, a server with a higher access speed can process a larger amount of traffic data, and a server with a lower access speed can process a smaller amount of traffic data.
In another embodiment of the present invention, the data amount may be allocated to the server corresponding to each IP address based on the historical traffic load information of the server corresponding to each IP address. Such as: when a total of two IP addresses, that is, a third IP address and a fourth IP address, are determined, and it is determined from the historical traffic load information of the servers corresponding to the two IP addresses that the traffic load before the server corresponding to the third IP address is high, and the traffic load before the server corresponding to the fourth IP address is low, that is, the data amount of the traffic that can be processed by the server corresponding to the third IP address is small, and the data amount of the traffic that can be processed by the server corresponding to the fourth IP address is large, the preset traffic allocation information may allocate a small data amount to the third IP address and allocate a large data amount to the fourth IP address.
Step S103A: and sending each domain name resolution result to the client so that the client selects an IP address based on the flow indication information contained in the domain name resolution result and accesses the target website based on the selected IP address.
Specifically, each domain name resolution result includes one IP address and traffic indication information corresponding to the IP address, and the traffic indication information corresponding to each IP address indicates the data amount of traffic that can be processed by the server corresponding to the IP address, so that the client can determine the data amount of traffic that can be processed by the server corresponding to each IP address based on the traffic indication information included in the domain name resolution result, and can select an IP address and access the target website based on the selected IP address.
As can be seen from the above, after the client receives each domain name resolution result, the client may obtain a plurality of IP addresses, and the client needs to select an IP address from the plurality of IP addresses to access the target website, according to the solution provided by the embodiment of the present invention, the server may allocate data volume of a traffic that can be processed to the server corresponding to each IP based on preset traffic allocation information, and then obtain a domain name resolution result including the IP address and traffic indication information corresponding to the IP address, and further may send each domain name resolution result to the client, so that the client may select an IP address based on the traffic indication information included in the domain name resolution result, and further may access the target website based on the selected IP address, so that the server may control the total amount of the traffic that can be processed by different IP addresses of the target website.
Fig. 3 is a schematic flow chart of a third domain name resolution method according to an embodiment of the present invention, and as shown in fig. 3, compared with the embodiment shown in fig. 1, the step S102 may include the steps of: S102A.
Step S102A: and sequentially reading each piece of domain name information, inquiring an IP address corresponding to a domain name to be resolved in the domain name information after each piece of domain name information is read, and taking the IP address as a domain name resolution result.
Specifically, the server may determine a plurality of pieces of domain name information, and therefore may sequentially read each piece of domain name information, determine a domain name to be resolved in the domain name information, query an IP address corresponding to the domain name to be resolved in the domain name information, and use the IP address as a domain name resolution result.
In an embodiment of the present invention, each piece of domain name information is sequentially read, then a domain name to be resolved in the domain name information is determined, and an IP address corresponding to the domain name to be resolved in the domain name information is queried based on a recursive query method, where the recursive query method is the prior art, and a specific implementation manner is not described herein again.
As can be seen from the above, since the server can determine a plurality of pieces of domain name information, it can sequentially read each piece of domain name information, then determine the domain name to be resolved in the domain name information, query the IP address corresponding to the domain name to be resolved in the domain name information, and use the IP address as a domain name resolution result. Therefore, the scheme provided by the embodiment of the invention can be used for analyzing the domain name to be analyzed in the determined domain name information.
Fig. 4 is a schematic flow chart of a fourth domain name resolution method according to an embodiment of the present invention, and as shown in fig. 4, compared with the embodiment shown in fig. 1, the step S103 may include the steps of: S103B-S103C.
Step S103B: and when determining that the client has a result combination requirement, combining the domain name resolution results, and sending a combination result to the client.
Specifically, the server may determine a plurality of domain name resolution results, so before sending the plurality of domain name resolution results to the client, it may determine whether the client has a result combination requirement, and if the client has the result combination requirement, the domain name resolution results may be combined to obtain a combined result, and then the combined result is sent to the client.
In an embodiment of the present invention, a list-form merged result may be created in advance, each domain name resolution result is then sequentially added to the merged result, and after all domain name resolution results are added to the merged result, the merged result is sent to the client.
Step S103C: and when determining that the client does not have a result combination requirement, respectively sending each domain name resolution result to the client.
Specifically, the server may determine a plurality of domain name resolution results, so before sending the plurality of domain name resolution results to the client, it may be determined whether the client has a result combination requirement, and if the client does not have the result combination requirement, the server may send the domain name resolution results to the client in sequence.
As can be seen from the above, since the server can determine a plurality of domain name resolution results, before sending a plurality of domain name resolution results to the client, it can be determined whether the client has a result combination requirement, if it is determined that the client has the result combination requirement, the domain name resolution results can be combined to obtain a combination result, and then the combination result is sent to the client, and if it is determined that the client does not have the result combination requirement, the domain name resolution results can be sequentially sent to the client.
In addition, an embodiment of the present invention may further provide a domain name resolution system, where the domain name resolution system includes a client, a server, and a domain name resolution device.
The server may be configured with a domain name management unit and a domain name resolution unit in advance, where the domain name management unit is configured to store a plurality of pieces of domain name information and the traffic allocation information, and the domain name resolution unit is configured to resolve a domain name to be resolved in each piece of domain name information based on an http (HyperText Transfer Protocol) Protocol.
The client may be an electronic device such as a mobile phone, a TV (Television), a computer, a tablet computer, and the like, where the client may be configured with an SDK (Software Development Kit) in advance, the client may send a domain name resolution request to the server based on the SDK, and the domain name resolution request sent based on the SDK may be received by the domain name resolution unit.
Fig. 5 is a schematic flowchart of a domain name resolution system provided in the implementation of the present invention, and as shown in fig. 5, the method may include the following steps: S501-S507.
Step S501: and the client sends a domain name resolution request to the server under the condition that the client needs to access the target website.
Step S502: the server side responds to a domain name resolution request sent by the client side and reads each piece of locally stored domain name information.
Step S503: and the server side reads each piece of domain name information in sequence, and inquires the IP address corresponding to the domain name to be analyzed in the domain name information to the domain name analyzing equipment based on a recursive inquiry method after each piece of domain name information is read.
Step S504: and the domain name resolution equipment sends the IP address corresponding to the domain name to be resolved in the domain name information to the server.
Step S505: and the server takes the IP address corresponding to the domain name to be resolved in the domain name information as a domain name resolution result.
Step S506: and the server side sends each domain name resolution result to the client side.
Step S507: and the client accesses the target website based on each domain name resolution result.
Specifically, the specific implementation method in steps S501 to S507 has been described in detail above, and is not described herein again.
Fig. 6 is a schematic structural diagram of a first domain name resolution device according to an embodiment of the present invention, where a server stores multiple pieces of domain name information, each piece of domain name information records a domain name to be resolved, and the domain name to be resolved recorded in each piece of domain name information corresponds to an IP address of a different server for operating a target website, as shown in fig. 6, the device includes the following modules: 601-603.
The domain name information reading module 601: responding to a domain name resolution request sent by a client, and reading each piece of locally stored domain name information;
