Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a WHOIS query method provided in an embodiment of the present application. The method is performed by an advanced message queue protocol server.

As shown in fig. 1, the method includes:

step 110, receiving a query domain name, where the query domain name is obtained by analyzing from the WHOIS query request by the WHOIS client.

In the embodiment of the application, a plurality of users send WHOIS query requests to a high-level message queue protocol server through a WHOIS client. The advanced message queue protocol server obtains the query domain name from the WHOIS query request. Wherein the WHOIS client may also be a WHOIS WEB page. The manner in which the user enters the WHOIS query request may be accomplished through interaction with the client.

The amqp (advanced Message Queuing protocol) is an application layer standard advanced Message Queuing protocol for providing unified Message service, is an open standard of the application layer protocol, and is designed for a Message-oriented middleware. The client and the message middleware based on the protocol can transfer messages and are not limited by conditions of different products, different development languages and the like of the client/middleware.

And step 120, determining the address of the WHOIS server corresponding to the top-level domain of the query domain name according to the top-level domain.

In the embodiment of the application, after receiving a plurality of WHOIS query requests, the AMQP server may obtain a query domain name from the WHOIS query requests, and then determine a corresponding WHOIS server address according to a top-level domain of the query domain name. The top level domain can be understood as the last part of the domain name, the letter combination after the last point of the domain name, and the type of the top level domain can be a top level domain of a country level region, a general top level domain, an infrastructure top level domain, a test top level domain and the like.

For example, on the Internet, top-level domain names such as ". com" and ". org".

And step 130, acquiring a first query server set corresponding to the WHOIS server address according to the WHOIS server address.

The mapping relationship between the query server and the WHOIS server may be established in the AMQP server according to various data structures. For example, a mapping relationship between the query server and an IP address is established according to the IP address provided by a certain WHOIS service provider. Wherein the same WHOIS service provider may provide multiple WHOIS server addresses. Each WHOIS server address may correspond to multiple query servers. Multiple query servers associated with the same WHOIS server address may be referred to as a query server set. For the sake of distinction, it may be defined by the terms first, second, etc., but not by the order of operations. For example, the first set of query servers and the second set of query servers may all be associated with the same WHOIS server address, and for example, the first set of query servers and the second set of query servers may also be referred to as a first subset of query servers or a second subset of query servers.

Step 140, selecting any first query server in the first query server set, and sending the query domain name to the WHOIS server corresponding to the address of the WHOIS server through the first query server.

And the AMQP server selects one query server from the first query server set according to a preset selection algorithm, and the query server is used for sending the query domain name to the WHOIS server.

And 150, receiving a query result returned by the first query server, wherein the query result is information returned by the WHOIS server according to the query domain name.

After receiving the information returned by the query server, the AMQP server identifies the information. Because the same WHOIS server is queried for multiple times in a short time, the blocking mechanism of the WHOIS server blocks part or all query servers related to the WHOIS server, so that the AMQP server cannot acquire the result of the query request. For example, if one of the query servers associated with the WHOIS server is blocked, or all of the query servers associated with the WHOIS server are blocked, the AMQP server may identify the blocked result and then use a corresponding query policy to further obtain the result of the query request.

Step 160, adjusting the query policy based on the query result to obtain WHOIS query information corresponding to the queried domain name.

In the embodiment of the present application, the query result returned by the query server may be, for example, that part of the plurality of query servers associated with the WHOIS server is blocked, or that all query servers associated with the WHOIS server are blocked. Based on partial blocking or full blocking, the AMQP server may enable different query policies to further obtain WHOIS query information corresponding to the queried domain name. For example, if one of the plurality of query servers associated with the WHOIS server is blocked, the AMQP server may select another of the plurality of query servers to further forward the query request to the WHOIS server. Or after all the query servers associated with the WHOIS server are blocked, the AMQP server may also implement WHOIS query by starting a new query server, thereby improving user experience and greatly reducing query delay caused by a blocking mechanism.

Based on the above embodiment, the query policy is further adjusted by the query result to provide the query result to the WHOIS client. Referring to fig. 2, fig. 2 shows a schematic flow chart of the present application with respect to step 160.

As shown in figure 2 of the drawings, in which,

at step 210, the information type of the query result is identified.

Step 220, if the information type is indication information, where the indication information includes information for indicating a status of each first query server in the first set of query servers, parsing the indication information: and

and step 230, adjusting the query strategy according to the analysis result to acquire WHOIS query information corresponding to the queried domain name.

According to the method and the device, different query strategies are triggered by identifying the information type of the query result returned by the query server through the AMQP server. For example, the query server returns indication information to the AMQP server, which may be set as specified by the AMQP protocol, the contents of which include information indicating the status of each query server in the first set of query servers. The status of the query server is blocked, e.g. by the WHOIS server, with an identification information indication, or a status value indication, e.g. in the form of a binary value, e.g. 1 for blocking and 0 for unblocking.

The method comprises the steps of inquiring a database, acquiring ports of a plurality of inquiry servers associated with a certain WHOIS server address from the database, identifying whether the inquiry server corresponding to the port is blocked by the WHOIS server or not through a state identifier corresponding to the port, further judging whether the ports of the plurality of inquiry servers associated with the WHOIS server address are all blocked or not, and triggering different inquiry strategies based on the judgment result to improve the inquiry speed.

Step 230 may also include:

step 2301, if the analysis result is that each first query server in the first query server set is in a state of being blocked by a WHOIS server, selecting any second query server in the second query server set, and establishing communication with the WHOIS server through the second query server to obtain WHOIS query information corresponding to the queried domain name.

Step 2302, if the analysis result is that a part of the first query servers in the first query server set are in a state of being blocked by the WHOIS server, selecting any one of the first query servers in another part of the first query server set, and establishing communication with the WHOIS server through the first query server to acquire WHOIS query information corresponding to the queried domain name.

In the embodiment of the present application, if the AMQP server identifies that all query servers related to the WHOIS server are blocked by the AMQP server, in order to further increase the processing speed, a new query server may be started to obtain a query result. If the AMQP server identifies a portion associated with the WHOIS server, e.g., 1 or 2 query servers are blocked, then the other query servers associated with the WHOIS server are selected to obtain the query results.

Step 240, after step 210, if the information type is WHOIS query information, then the WHOIS query information is sent to the WHOIS client.

According to the embodiment of the application, after the information type of the query result is identified to be the WHOIS query information, the WHOIS query information is directly sent to the WHOIS client, and the query result is presented to the user.

According to the method and the device, the AMQP server is triggered to adjust the query strategy to improve the query processing speed and improve the user experience degree by identifying the information type fed back to the AMQP server by the query server.

It should be noted that while the operations of the method of the present invention are depicted in the drawings in a particular order, this does not require or imply that the operations must be performed in this particular order, or that all of the illustrated operations must be performed, to achieve desirable results. Rather, the steps depicted in the flowcharts may change order of execution. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions.

With further reference to fig. 3, fig. 3 shows an exemplary structural block diagram of the WHOIS query apparatus provided in the embodiment of the present application. The apparatus may be implemented by an advanced message queue protocol server.

As shown in fig. 3, the apparatus includes:

the first receiving module 310 is configured to receive a query domain name, where the query domain name is obtained by analyzing from a WHOIS query request by a WHOIS client.

The determining module 320 is configured to determine, according to the top-level domain of the queried domain name, the WHOIS server address corresponding to the top-level domain.

The obtaining module 330 is configured to obtain, according to the address of the WHOIS server, a first query server set corresponding to the WHOIS server.

The mapping relationship between the query server and the WHOIS server may be established in the AMQP server according to various data structures. For example, a mapping relationship between the query server and an IP address is established according to the IP address provided by a certain WHOIS service provider. Wherein the same WHOIS service provider may provide multiple WHOIS server addresses. Each WHOIS server address may correspond to multiple query servers. Multiple query servers associated with the same WHOIS server address may be referred to as a query server set. For the sake of distinction, it may be defined by the terms first, second, etc., but not by the order of operations. For example, the first query server set and the second query server set may be associated with the same WHOIS server address, and for example, the first query server set and the second query server set may also be referred to as a first subset of query servers or a second subset of query servers.

The selecting module 340 is configured to select any first query server in the first query server set, and send the query domain name to the WHOIS server corresponding to the address of the WHOIS server through the first query server.

A second receiving module 350, configured to receive a query result returned by the first query server, where the query result is information returned by the WHOIS server according to the query domain name.

After receiving the information returned by the query server, the AMQP server identifies the information. Because the same WHOIS server is queried for multiple times in a short time, a blocking mechanism of the WHOIS server blocks part or all query servers related to the WHOIS server, so that the AMQP server cannot acquire the result of the query request. For example, if one of the query servers associated with the WHOIS server is blocked, or all of the query servers associated with the WHOIS server are blocked, the AMQP server may identify the blocked result and then use a corresponding query policy to further obtain the result of the query request.

And an adjusting module 360, configured to adjust the query policy based on the query result to obtain WHOIS query information corresponding to the query domain name.

On the basis of the above embodiment, the query policy is further adjusted by the query result to provide the query result to the WHOIS client. Referring to fig. 4, fig. 4 shows an exemplary block diagram of the adjusting module 360 according to the present application.

As shown in the figure 4 of the drawings,

and the identifying submodule 410 is used for identifying the information type of the query result.

The parsing sub-module 420 is configured to parse the indication information if the information type is indication information, where the indication information includes information used to indicate a status of each first query server in the first set of query servers; and

and the adjusting sub-module 430 is configured to adjust the query policy according to the analysis result to obtain WHOIS query information corresponding to the queried domain name.

According to the method and the device, different query strategies are triggered by identifying the information type of the query result returned by the query server through the AMQP server. For example, the query server returns to the AMQP server indication information, which may be set as specified by the AMQP protocol, whose contents include information indicating the status of each query server in the first set of query servers. The status of the query server is blocked, e.g. by the WHOIS server, with an identification information indication, or a status value indication, e.g. in the form of a binary value, e.g. 1 for blocking and 0 for unblocking.

The adjustment sub-module 430 may further include:

a first selecting unit 4301, configured to select any one second query server in the second query server set if the analysis result indicates that each first query server in the first query server set is in a state of being blocked by a WHOIS server, and acquire WHOIS query information corresponding to the queried domain name by establishing communication between the second query server and the WHOIS server.

A second selecting unit 4302, configured to select any one of the first query servers in another part of the first query server set if the analysis result is that some of the first query servers in the first query server set are in a state of being blocked by the WHOIS server, and acquire WHOIS query information corresponding to the queried domain name by establishing communication between the first query server and the WHOIS server.

A sending sub-module 440, after the identifying sub-module 410, configured to send the WHOIS query information to the WHOIS client if the information type is the WHOIS query information.

In the embodiment of the application, after the information type of the query result is identified as the WHOIS query information, the WHOIS query information is directly sent to the WHOIS client side, and the query result is presented to the user.

It should be understood that the units or modules recited in the apparatus 400 correspond to the various steps in the method described with reference to fig. 2.
