Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those 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 server device capable of deploying a network access function, such as a device equipped with a centros (Community Enterprise Operating System) System DELL (DELL) rack server host, or a device providing a Linux System Docker (application container engine) service, such as an aristo service. The domain name allocation method may include:
step 101: and receiving an access request from an access terminal, wherein the access request comprises the identifier of the access terminal.
In this embodiment, the access terminal may include hardware and/or software. The access terminal may be an electronic device having a display screen, including but not limited to a smart phone, a tablet computer, an e-book reader, an MP3 player (Moving Picture Experts Group Audio Layer III, mpeg compression standard Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, mpeg compression standard Audio Layer 4), a laptop, a desktop computer, and the like. The access request of the access terminal can be received by the domain name allocation device or a special request module.
In this embodiment, the access request may be, for example, an HTTP (HyperText Transfer Protocol) access request, an HTTPs (HyperText Transfer Protocol over secure key Layer) access request, or the like. The access request may be for requesting access to any website.
In this embodiment, the identifier of the access terminal may be an identifier used to distinguish one access terminal from other access terminals, for example, an IP (Internet Protocol) address of the access terminal device, an Identity Document (Identity Document) of the access terminal, 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, an IMEI (International Mobile Equipment Identity, also called International Mobile Equipment Identity). If the Access terminal is a computer device, the identifier of the Access terminal may specifically be a Media Access Control (MAC) 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 predetermined Algorithm may be any method capable of converting the identifier into a value, such as a Secure Hash Algorithm (SHA), which may specifically be SHA-1, SHA-224, SHA-256, SHA-384, or SHA-512. A pre-set algorithm is used to map the identification to a transformed value. The converted value may be a number or a combination of a letter and a number. When the conversion value is a number, it may be specifically, 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, the methods used when converting the identifier into the conversion value are the same for all the access terminals and whether to access a website for the first time, so that the steps executed for converting the same identifier and the converted conversion value are the same each time.
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 corresponding relationship between the available domain name and the conversion value can be found through the conversion value according to the set search rule, and then the available domain name can be further found through the corresponding relationship.
In this embodiment, the available domain names may include domain names for accessing a certain website. For example, a domain name that is not masked by a website requested to be accessed by verification may be used in any environment for a user who needs to access the website. More than two available domain names can be set for one website to avoid the situation that one available domain name is shielded to cause the website requesting access to be inaccessible. If a plurality of available domain names are set, when one available domain name is shielded, the remaining available domain names can be allocated to the user equipment accessing the website, and the access to the website is not influenced by shielding of a certain domain name.
In this embodiment, for a website that requests access, the correspondence between two or more different available domain names and conversion values may be set in advance. The corresponding relationship can be realized by a list or an index and the like.
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 conversion value of the identifier is allocated to the access terminal, and may be that the available domain name is sent to the access terminal, so that the access terminal can use the available domain name to access the website requested to be accessed. And allocating the available domain name corresponding to the conversion value of the identifier to the access terminal, or accessing the website requested to be accessed by using the corresponding available domain name and feeding back the access result to the access terminal.
In the embodiment of the application, after an access request of an access terminal is received, the identifier of the access terminal is converted to obtain a conversion value corresponding to the identifier of the access terminal, and then an 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. Therefore, the same available domain name can be obtained for the same access terminal every time the same website is accessed, and the user information in the Cookie (data stored on the local terminal of the user) cannot be lost due to the change of the domain name. In addition, in general, in order to ensure the access speed, information needed to be used for confirming the available domain name needs to be stored in the cache, the embodiment of the application only needs to store the corresponding relation between the available domain name and the conversion value in the cache, the total number of the conversion value can be set, a large amount of storage space cannot be occupied, the conversion value is adaptive to the storage capacity of the cache, the storage cost is reduced, and the operation efficiency is improved.
In one embodiment, the method for converting an identifier of an access terminal into an IP address of the access terminal by using a preset algorithm to obtain a conversion 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 the conversion values;
the absolute value is taken as the conversion value of the identification.
For example, if the total number of converted values is 10, the hash code mantissa may be used as the identified converted 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 a set value, so that under the condition of mass 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 small 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 small. 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 distributed to the access terminal, the corresponding relation can be directly searched from the cache, and the domain name distribution 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 the converted value in other manners, such as by using the last bit of the IP address as the identified converted value.
In this embodiment, the hash code may be an Integer class hash code.
In other embodiments, when the identifier of the access terminal is other kinds of identifiers, the hash code of the identified Object class or the hash code of the String class can be calculated by using a hash algorithm.
In one embodiment, before looking up the available domain name corresponding to the identified conversion value, the domain name assignment method further comprises: and setting the corresponding relation between the available domain name and the conversion value.
In the embodiment of the present application, the corresponding relationship between the available domain name and the conversion value is set, and a corresponding available domain name can be set for each conversion value, so that the available domain name can be acquired under the condition that the conversion value is known. In the correspondence, the conversion value may be non-repetitive, and the available domain name may be repetitive. That is, there may be cases where more than two conversion values correspond to one available domain name.
In one embodiment, setting the correspondence between the available domain name and the conversion value includes:
a domain name list is established, each transition value in the domain name list corresponding to an available domain name. Therefore, the conversion value obtained by the identifier of the access terminal by adopting the preset algorithm can be used for searching the corresponding available domain name in the preset corresponding relation.
In this embodiment, the domain name list may include a set number of entries, where each entry corresponds to a conversion value, and each conversion value corresponds to an available domain name. The present application is not limited to this case, and more than two entries may correspond to the same available domain name.
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 less 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: and when the available domain names are used up and residual conversion values which do not establish the corresponding relation with the available domain names exist, establishing the corresponding relation between the arranged available domain names and the residual conversion values in sequence.
In this embodiment, the available domain names are arranged in a certain order, and then the available domain names are sequentially associated with the conversion values; establishing a corresponding relation between a first one of the arranged available domain names and a first conversion value; the second of the ranked available domain names is mapped … … to the second converted value until the last available domain name. And if the arranged domain names are used up and conversion values of the available domain names which do not correspond to the domain names still exist, recycling the arranged available domain names. Specifically, for example, if there are 5 available domain names and 10 conversion values are preset, the 5 available domain names are arranged, and the arranged 5 available domain names sequentially establish a corresponding relationship with the first 5 conversion values and the last 5 conversion values. Thus, the first conversion value and the sixth conversion value correspond to the first arranged available domain name, the second conversion value and the seventh conversion value correspond to the second arranged available domain name, and so on, and the fifth conversion value and the tenth conversion value correspond to the fifth arranged available domain name.
In other embodiments, as shown in fig. 3, one example of establishing a list of domain names may include:
step 301: all available domain names for a web site are stored in a set. For example, if a website has 6 available domain names, the 6 available domain names for the website are put into a set.
Step 302: and judging whether a conversion value which does not establish a corresponding relation with the available domain name exists.
Step 303: it is determined whether there is a domain name available in the set.
If there is an available domain name in the set and there is a conversion value that does not establish a correspondence with the available domain name, step 304 is executed. If there is no available domain name in the set and there is a conversion value that does not establish a correspondence relationship with the available domain name, then return to step 301.
For example, there are 10 conversion values that need to establish a correspondence relationship with an available domain name, and assuming that the number of conversion values that do not establish a correspondence relationship with an available domain name is 2, there are conversion values that establish a correspondence relationship with an available domain name.
Step 304: if the set has an available domain name and a conversion value which does not establish a corresponding relationship with the available domain name exists, taking out one available domain name in the set and establishing a corresponding relationship with the conversion value which does not establish a corresponding relationship with the available domain name.
For example, if there are 6 available domain names in the set, one available domain name is taken out of the set, and 5 available domain names remain.
Step 302 and step 303 may be executed without any sequence or in any sequence. And if the conversion value which does not establish the corresponding relation with the available domain name does not exist, ending the process, and finishing the establishment of the corresponding relation between the conversion value and the available domain name.
In one embodiment, the access request further includes a website address requesting access; the domain name allocation method further comprises the following steps: one or more available domain names included in the web address are obtained.
In this embodiment, the number of available domain names is generally multiple.
In one embodiment, as shown in fig. 4, the domain name allocation method further includes:
step 401: detecting shielded domain names in the available domain names;
step 402: if an unmasked new domain name other than the available domain name exists, replacing the masked domain name with the new domain name;
step 403: if no new domain name exists, replacing the masked domain name by an unmasked domain name in the available domain names.
In this embodiment, after an available domain name has been used for a period of time, there may be a masked condition. For example, the available domain names may be periodically detected by a third party tool to find masked domain names. If an unmasked new domain name other than 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 originally corresponding to the masked domain name is established. For example, the correspondence between the new domain name and a certain conversion value is stored in the domain name list. And if the newly generated available domain name does not exist, selecting one available domain name from the rest available domain names, and establishing a corresponding relation with the originally corresponding conversion value of the shielded domain name.
In this embodiment, if the original available domain name is masked and there is no unmasked new domain name other than the available domain name, one of the available domain names that is unmasked and has a smaller number of corresponding conversion values is used to replace the masked domain name.
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 determined according to the access result.
In this embodiment, it may be preferentially determined whether an unmasked new domain name other than the available domain names exists, and if not, one unmasked domain name in the available domain names is used to replace the masked domain name.
In one specific example, the list of available domain names is shown in table 1, and the available domain names include 5, i.e., available domain name 1, available domain name 2, available domain name 3, available domain name 4, and available domain name 5. The number of conversion values is set to 10, and is 0 to 9. There should be 10 entries in the domain name list. The conversion values 0-4 correspond to the available domain names 1-5 in sequence, and the conversion values 5-9 correspond to the available domain names 1-5 in sequence.

| 5 | Available Domain name 1 |
| 6 | Available Domain name 2 |
| 7 | Available domain name 3 |
| 8 | Available Domain name 4 |
| 9 | Available Domain name 5 |
TABLE 1
In other embodiments, the available domain names may not be arranged, and if the number of the available domain names is smaller than the number of the conversion values, a correspondence between the available domain names and the conversion values is randomly established, and the number of the conversion values corresponding to each domain name is as average as possible when the correspondence 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, then available domain name 1 will be replaced with available domain name 6 such that the transition values 0 and 5 correspond to available domain name 6.
| Converted value | Available domain name |
| 0 | Available Domain name 6 |
| 1 | Available Domain name 2 |
| 2 | Available domain name 3 |

| 5 | Available Domain name 6 |
| 6 | Available Domain name 2 |
| 7 | Available domain name 3 |
| 8 | Available Domain name 4 |
| 9 | Available Domain name 5 |
TABLE 2
In another specific example, as shown in table 3 below, if the available domain name 1 is masked and there is no newly generated available domain name, then one of the available domain names 2-5 is selected, specifically, for example, the available domain name 2, so that the conversion values 0 and 5 correspond to the available domain name 2.
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, two available domain names are selected from the available domain names 2-5, specifically, for example, the available domain name 2 and the available domain name 3, so that the conversion values 0 and 5 correspond to the available domain name 2 and the available domain name 3, respectively.
