Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Reference in the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.
Referring to fig. 1, the domain name assignment method provided in the embodiment of the present application may be applied to a domain name assignment device, and mainly refers to a device capable of deploying a server device that provides a network access function, such as a DELL (DELL) rack-mounted server host equipped with a CentOS (Community Enterprise Operating System ) system, or a device that provides a Docker (application container engine) service of a Linux system, such as an alicloud service. The domain name assignment method may include:
step 101: an access request from an access terminal is received, wherein the access request comprises an identification of the access terminal.
In this embodiment, the access terminal may include hardware and/or software. The access terminal may be an electronic device with a display screen including, but not limited to, a smart phone, tablet, e-book reader, MP3 player (Moving Picture Experts Group Audio Layer III, mpeg 3), MP4 (Moving Picture Experts Group Audio Layer IV, mpeg 4) player, laptop and desktop computer, etc. The access request of the access terminal can be received by domain name distribution equipment or by a special request module.
In this embodiment, the access request may be, for example, an HTTP (HyperText Transfer Protocol ) access request or an HTTPs (Hyper Text Transfer Protocol over SecureSocket Layer, hypertext transfer security protocol) access request, or the like. The access request may be used to request access to any web site.
In this embodiment, the identifier of the access terminal may be an identifier for distinguishing one access terminal from other access terminals, for example, an IP (Internet Protocol ) address of the access terminal device, an access terminal ID (Identity Document, an identification number), or a device number of the access terminal. If the access terminal is a mobile device, the device number of the access terminal may be, for example, IMEI (International Mobile Equipment Identity, international mobile equipment identifier, also called international mobile equipment identifier). If the access terminal is a computer device, the identifier of the access terminal may specifically be a MAC (Media Access Control ) address of the access terminal.
Step 102: and converting the identifier through a preset algorithm to obtain a conversion value of the identifier.
In this embodiment, the preset algorithm may be any method capable of converting the identifier into a value, such as a secure hash algorithm (Secure Hash Algorithm, SHA), specifically SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, or the like. The preset algorithm is used for mapping the identification to a conversion value. The conversion value may be a number or a combination of letters and numbers. When the converted value is a number, it may be, for example, a binary number, an octal number, a decimal number, a hexadecimal number, or the like.
In this embodiment, the preset algorithm may be a unified algorithm, that is, for all access ends and whether to access a website for the first time, the method used when converting the identifier into the conversion value is the same, so that the steps executed by converting the same identifier each time and the converted conversion value are the same.
Step 103: and searching the available domain name corresponding to the identified conversion value in the corresponding relation between the available domain name and the conversion value.
In this embodiment, after the conversion value corresponding to the identifier is calculated, the correspondence between the available domain name and the conversion value may be found through the conversion value according to the set search rule, and then the available domain name may be further found through the correspondence.
In this embodiment, the available domain name may include a domain name for accessing a website. For example, a domain name masked by a website which is verified not to be requested for access may access the website in any environment, and this domain name is available to a user who needs to access the website. For a web site, more than two available domain names may be set to avoid situations where one available domain name is masked and the web site requesting access cannot be accessed. If a plurality of available domain names are set, when one available domain name is shielded, the rest available domain names can be allocated to the user equipment accessing the website, and the access to the website is not affected because a certain domain name is shielded.
In this embodiment, for a website that requests access, the correspondence between two or more different available domain names and conversion values may be preset. The correspondence may be implemented by a list or an index.
Step 104: and allocating the available domain name corresponding to the identified conversion value to the access terminal.
In this embodiment, the available domain name corresponding to the identified conversion value is allocated to the access terminal, and the available domain name may be sent to the access terminal, so that the access terminal can access the website that requests access by using the available domain name. And distributing the available domain name corresponding to the identified conversion value to the access terminal, or utilizing the corresponding available domain name to access the website accessed by the request, and feeding back the access result to the access terminal.
In the embodiment of the application, after receiving the access request of the access terminal, the identifier of the access terminal is converted to obtain the conversion value corresponding to the identifier of the access terminal, and then the available domain name corresponding to the conversion value is obtained, so that the access terminal can access the website by using the available domain name. Thus, for the same access terminal, the same available domain name can be obtained each time the same website is accessed, and user information in the Cookie (data stored on the user local terminal) is not lost due to the change of the domain name. In addition, generally, in order to ensure the access speed, information required to be used for confirming the available domain name is required to be stored in the cache, and in the embodiment of the application, only the corresponding relation between the available domain name and the conversion value is required to be stored in the cache, so that the total number of the conversion values can be set, a large amount of storage space is not occupied, the storage capacity of the cache is adapted, the storage cost is reduced, and the operation efficiency is improved.
In one embodiment, the identifier of the access terminal is an IP address of the access terminal, and the converting the identifier by a preset algorithm to obtain a converted value of the identifier includes:
calculating a Hash Code (Hash Code) of the IP address by using a Hash algorithm;
calculating the absolute value of the remainder obtained by dividing the hash code by the total number of conversion values;
the absolute value is taken as the identified conversion value.
For example, if the total number of conversion values is 10, the hash mantissa may be used as the identified conversion value. Thus, the conversion value is a number from 0 to 9.
In the embodiment of the application, the total number of the conversion values is the set value, so that under the condition of massive users, only the corresponding relation between the conversion values and the available domain names is stored. Because the corresponding relation between the conversion value and the available domain name is consistent with the number of the conversion values, the total number of the conversion values can be controlled within a smaller number, so that the number of the corresponding relation between the conversion value and the available domain name is the same as the total number of the conversion values, and the occupied storage space is smaller. Therefore, the corresponding relation between the conversion value and the available domain name can be stored in the cache, so that when the available domain name is allocated to the access terminal, the corresponding relation can be directly searched from the cache, and the domain name allocation speed is ensured. The process of calculating the access terminal identification to obtain the conversion value consumes less time and less memory, and can ensure higher domain name distribution efficiency.
In other embodiments, the IP address may be converted to a conversion value in other ways, such as, for example, having the last bit of the IP address as the identified conversion value.
In this embodiment, the hash code may be an intelger (Integer) type hash code.
In other embodiments, when the identifier of the access terminal is another kind of identifier, a hash algorithm may be used to calculate a hash code of the Object class of the identifier, or a hash code of the String class.
In one embodiment, before searching for an available domain name corresponding to the identified conversion value, the domain name assignment method further includes: and setting the corresponding relation between the available domain name and the conversion value.
In the embodiment of the present application, the correspondence between the available domain name and the conversion value is set, and the corresponding available domain name may be set for each conversion value, so that the available domain name may be obtained under the condition that the conversion value is known. In the correspondence, the converted value may be non-duplicate and the available domain name may be duplicate. That is, there may be cases where more than two converted values correspond to one available domain name.
In one embodiment, setting the correspondence between the available domain name and the converted value includes:
a list of domain names is created, each conversion value in the list of domain names corresponding to an available domain name. Therefore, the conversion value obtained by adopting a preset algorithm for the identification of the access terminal can find the corresponding available domain name in the preset corresponding relation.
In the embodiment of the present application, the domain name list may include a set number of entries, each entry corresponding to a conversion value, and each conversion value corresponding to an available domain name. It may also happen that more than two entries correspond to the same available domain name, which is not limited in this application.
In one embodiment, as shown in fig. 2, establishing the domain name list further includes:
step 201: if the number of the available domain names is smaller than the total number of the conversion values in the domain name list, arranging the available domain names;
step 202: establishing a corresponding relation between the arranged available domain names and each conversion value in sequence;
step 203: when the available domain name is used up and the residual conversion value which does not have the corresponding relation with the available domain name exists, the arranged available domain name and the residual conversion value are sequentially in the corresponding relation.
In this embodiment, the available domain names are arranged according to a certain order, and then a corresponding relation is established between the available domain names and the conversion values in sequence; establishing a corresponding relation between a first one of the arranged available domain names and a first conversion value; and establishing a corresponding relation … … between the second one of the arranged available domain names and the second conversion value until the last available domain name. If the arranged domain names are used up, and still there is no conversion value of the corresponding available domain names, recycling the arranged available domain names. Specifically, for example, if there are 5 available domain names and the preset conversion values are 10 in total, the 5 available domain names are arranged, and the arranged 5 available domain names and the first 5 conversion values and the last 5 conversion values sequentially establish a corresponding relationship. So that the first conversion value and the sixth conversion value correspond to the first available domain name after arrangement, the second conversion value and the seventh conversion value correspond to the second available domain name after arrangement, and so on, and the fifth conversion value and the tenth conversion value correspond to the fifth available domain name after arrangement.
In other embodiments, as shown in fig. 3, one example of establishing a domain name list may include:
step 301: all available domain names for the web site are stored in a collection. For example, if a web site has 6 available domain names, then the 6 available domain names for the web site are put into a collection.
Step 302: and judging whether a conversion value which does not establish a corresponding relation with the available domain name exists or not.
Step 303: it is determined whether there are domain names available in the collection.
If there is a domain name available in the set and there is a converted value that does not have a correspondence with the available domain name, step 304 is performed. If there is no domain name available in the set and there is a converted value that does not have a correspondence with the available domain name, the process returns to step 301.
For example, there are 10 conversion values that need to be associated with the available domain name, and if the number of conversion values that do not have to be associated with the available domain name is 2, there are conversion values that have to be associated with the available domain name.
Step 304: if the available domain names exist in the set and the conversion values which do not establish the corresponding relation with the available domain names exist, one available domain name in the set is taken out, and the corresponding relation is established with the conversion values which do not establish the corresponding relation with the available domain names.
For example, if there are 6 available domain names in the set, one available domain name is fetched from the set, leaving 5 available domain names.
Steps 302, 303 may be performed out of order, or in any order. And if the conversion value which does not have the corresponding relation with the available domain name exists, ending, and finishing the establishment of the corresponding relation between the conversion value and the available domain name.
In one embodiment, the access request further comprises a website for requesting access; the domain name assignment method further comprises the following steps: one or more available domain names included in the web address are obtained.
In this embodiment, the available domain names are typically multiple.
In one embodiment, as shown in fig. 4, the domain name assignment method further includes:
step 401: detecting a masked domain name from the available domain names;
step 402: if there is an unmasked new domain name other than the available domain name, replacing the masked domain name with the new domain name;
step 403: if no new domain name exists, the masked domain name is replaced with an unmasked domain name from among the available domain names.
In this embodiment, after a period of use of an available domain name, there may be a masked situation. For example, the available domain names may be periodically checked by a third party tool for masked domain names. If an unmasked new domain name except the available domain name exists, the new domain name can access the target website, and the corresponding relation between the new domain name and the conversion value corresponding to the original domain name of the masked domain name is established. For example, the correspondence between a new domain name and a certain conversion value is stored in the domain name list. If the newly generated available domain name does not exist, one available domain name is selected from the rest available domain names, and a corresponding relation is established between the available domain name and the conversion value corresponding to the shielded domain name script.
In this embodiment, if the original available domain name is masked and there is no new domain name that is not masked other than the available domain name, then the masked domain name is replaced with one of the available domain names that is not masked and has a smaller number of corresponding conversion values.
In this embodiment, the available domain name may be detected according to a set detection period. The detection mode may specifically be that the detected available domain name is used to access the website, and whether the available domain name is shielded is judged according to the access result.
In this embodiment, it may be preferentially determined whether there is an unmasked new domain name other than the available domain name, and if not, one of the available domain names is used to replace the masked domain name.
In a specific example, the list of available domain names is shown in table 1, and the available domain names include 5, which are available domain name 1, available domain name 2, available domain name 3, available domain name 4, and available domain name 5, respectively. The number of conversion values is 10 and is 0-9. The entries in the domain name list have 10 entries accordingly. The conversion values 0-4 correspond to the available domain names 1-5 in turn, and the conversion values 5-9 correspond to the available domain names 1-5 in turn.

| 6 | Available Domain name 2 |
| 7 | Available Domain name 3 |
| 8 | Available Domain name 4 |

TABLE 1
In other embodiments, the available domain names may not be arranged, if the number of the available domain names is smaller than the number of the conversion values, a corresponding relation is established between the available domain names and the conversion values, and the number of the conversion values corresponding to the domain names is as average as possible when the corresponding relation is established.
In another specific example, as shown in table 2, if available domain name 1 is masked and there is a newly generated available domain name 6, available domain name 6 is substituted for available domain name 1 such that conversion values 0 and 5 correspond to available domain name 6.

In another specific example, as shown in table 3 below, if the available domain name 1 is masked, there is no newly generated available domain name, then one of the available domain names 2-5 is selected, specifically, for example, available domain name 2, such that the conversion values 0 and 5 correspond to the available domain name 2.
TABLE 3 Table 3
In another specific example, as shown in table 4 below, if the available domain name 1 is masked, there is no newly generated available domain name, and the available domain name corresponds to two conversion values in the original table 1, then two available domain names, specifically, for example, the available domain name 2 and the available domain name 3, are selected from the available domain names 2-5 such that the conversion values 0 and 5 correspond to the available domain name 2 and the available domain name 3, respectively.
