The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The following disclosure provides many different embodiments or examples for implementing different configurations of embodiments of the invention. In order to simplify the disclosure of embodiments of the invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, embodiments of the invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. In addition, embodiments of the present invention provide examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
As shown in fig. 2, a menu authority control method based on prime number multiplication includes the following steps:
establishing an authority table: establishing an authority name and an authority code, associating the authority name with the authority code, and giving different prime numbers to different authority codes;
a menu authority establishing step: constructing a menu id, capturing an authority name required by the menu id, and associating the menu relative path, the menu id and the authority name; establishing a menu authority total code under the menu id, wherein the menu authority total code is the product of authority codes selected in the menu id;
user authority establishing step: constructing a user id, capturing an authority name required by the user id, and associating the user id with the authority name; establishing a user authority total code under the user id, wherein the user authority total code is the product of authority codes required by the user id;
and (3) checking menu authority: and continuously subtracting the user authority total code from the menu authority total code until the difference value is smaller than the user authority total code to obtain a residual value, marking that the user id does not have the operation authority of the menu id when the residual value is not 0, and marking that the user id has the operation authority of the menu id when the residual value is not 0.
According to the definition of prime number and composite number, a natural number is called prime number if only 1 and the natural number have two factors; a natural number is called a composite number if it has other factors than 1 and itself. The menu authority total code and the user authority total code are obtained by multiplying the corresponding authority codes, and because the authority codes are prime numbers, namely the authority codes except 1 cannot be divided by other natural numbers, the authority codes corresponding to the menu authority total code and the product combination of the authority codes are obtained by multiplying the natural numbers except 1 of the menu authority total code, and the authority codes corresponding to the user authority total code and the product combination of the authority codes are obtained by multiplying the natural numbers except 1 of the user authority total code. Therefore, when the user authority total code is continuously subtracted from the menu authority total code, and the obtained residual value is not 0, the user authority total code is not multiplied to obtain the authority code corresponding to the menu authority total code and the product combination of the authority codes, that is, the authority code corresponding to the user Id is completely different from the authority code corresponding to the menu Id; and when the remaining value is 0, at least one of the authority codes corresponding to the user Id and the authority code corresponding to the menu Id is the same. Whether the user id has the operation authority under the menu id can be distinguished by judging whether the residual value is 0 or not, so that the storage of the relation among the authority, the role and the user is reduced, the running efficiency of an application system is improved, the risk of tampering by a third party can be effectively prevented, and the safety of the system is improved.
For example, the total menu authority code is 95(5 × 19 is 95), the total user authority code is 43, the total user authority code subtracted from the total menu authority code is 95-43 is 52, in which case 52 is greater than 43, and then 95-43-43 is executed to 9, in which case 11 is smaller than 43, 9 is a residual value, and the residual value 9 is not 0, and it is marked that the user id does not have the operation authority of the menu id, and the background does not need to care about the value of the quotient, and it is sufficient to simply find the residual value and determine whether the residual value is 0. In another embodiment, the authority code of the operation authority in the requested menu id is 9, and the obtained remaining value is 0, which marks that the user id has the operation authority of the menu id. Specifically, when the order of magnitude difference between the menu authority total code and the user authority total code is large, preferably, the order of magnitude difference is larger than five order of magnitude, the menu authority total code and the user authority total code are subjected to remainder, when the remainder is not 0, the user id is marked to have no operation authority of the menu id, and when the remainder is 0, the user id is marked to have the operation authority of the menu id.
In some embodiments, the user right establishing step further comprises: after the user id is constructed, checking the user id and checking a menu id needing authorization; and calculating a menu authority total code corresponding to the menu id needing authorization, and storing the value of the menu authority total code in a user authority total code corresponding to the user id. The user id corresponding to the page checking role and the authority name of the menu are recorded in the role-authority code value by calculating the product of the authority codes of the checked authority name in the background. In one embodiment, the permissions are checked, added, edited, deleted and exported for a user id corresponding to a certain role under a menu managed by a page user, and then the request parameters are a set of the user id, the menu id and the permission id code. The background will find the set of authority codes first, and then multiply the authority codes, in this embodiment, the set of authority codes is [2, 3, 5, 19, 23, 29 ], and then calculate 2 x 3 x 5 x 19 x 23 x 29, and obtain the corresponding authority total code of 380190. The database records are (role-authority table id, role id, user management menu id, 380190) as the role-authority table (role-authority table id, user id, menu id, user authority total code).
It should be noted that the step of establishing the authority table further includes: randomly grabbing prime numbers in a prime number table from 1 to 100, and giving the grabbed prime numbers to the authority codes according to time established by the authority names; after the prime number is randomly captured each time, whether the captured prime number is repeated with the prime number which is captured before is judged, and when the captured prime number is not repeated, the next prime number is captured. When a weight limit needs to be added to a certain menu page, the relative path, the menu id and the authority name of the certain menu page are recorded, the authority code of the certain menu page is automatically calculated in a background, for example, the prime number captured for the first time is 1, the prime number captured for the second time is 3, the prime number captured for the third time cannot be 1 or 3, but can be other prime numbers except 1 or 3, and after the prime number is captured, the grasped prime number is given to the authority code according to the time established by the authority name. In the step of establishing the authority list, the randomness of the authority total code can be increased by adopting a mode of randomly grabbing the prime numbers in the prime number list from 1 to 100, and the authority total code is prevented from being cracked by a malignant user due to a certain rule. In one embodiment, an additional operation authority is added to the menu managed by the user, and the existing recorded authority code managed by the user is 2. The newly added permission request parameters are as follows: "/user/add", "user management menu id", and "new user", respectively represent the menu relative path, menu id, and authority name. The authority code recorded in the menu id is queried in the background to be 2, and then the system can not capture the prime number of 2.
Optionally, in the menu permission establishing step, the menu permission total code is set to a format of a character string with a character length of 20; in the user authority establishing step, the user authority total code is set to be in a character string format with the character length of 20, and the situation that the product obtained by multiplying each prime number is too large to exceed the limit of the int digit of the computer is prevented. As the number of the setting of the authority codes increases, the value of the authority total code becomes larger. Based on business consideration, the same menu is not friendly to both a system and a user, is bloated, and is not friendly to later expansion, in the embodiment, the most friendly permission number supported by the permission scheme is 10, that is, the menu permission total code is set to be in a character string varchar (20) format, and the user permission total code is set to be in the character string varchar (20) format, which certainly can support more permissions, but it is not recommended to stack too many permissions in the same menu. If all the first 10 authority values are checked, the corresponding authority total code is 6469693230.
Specifically, the method further comprises an intercepting step, wherein the intercepting step comprises the following steps: and setting an interceptor in front of the controller, and intercepting the current operation of the user id when the residual value obtained in the menu authority verification step is not 0. Through the interceptor, the interception can be immediately carried out when the user id is identified to have no authority, so that the cross-authority operation of the non-authority user is avoided.
In some embodiments, as shown in fig. 3, a menu authority control system based on prime number multiplication includes an authority table establishing module, a menu authority establishing module, a user authority establishing module, and a menu authority verifying module; the authority table establishing module is used for establishing an authority name and an authority code, associating the authority name with the authority code and endowing different prime numbers to different authority codes; the menu authority establishing module is used for establishing a menu id, capturing an authority name required by the menu id and associating the menu relative path, the menu id and the authority name; the menu management system is also used for establishing a menu authority total code under the menu id, wherein the menu authority total code is the product of authority codes selected in the menu id; the user authority establishing module is used for establishing a user id, capturing an authority name required by the user id and associating the user id with the authority name; the system is also used for establishing a user authority total code under the user id, wherein the user authority total code is the product of authority codes required by the user id; the menu authority checking module is used for continuously subtracting the user authority total code from the menu authority total code until the difference value is smaller than the user authority total code to obtain a residual value, marking that the user id has no operation authority of the menu id when the residual value is not 0, and marking that the user id has the operation authority of the menu id when the residual value is not 0.
It is worth to be noted that the user authority establishing module is further used for checking a user id and checking a menu id which needs to be authorized; and the method is also used for calculating a menu authority total code corresponding to the menu id needing authorization and storing the value of the menu authority total code in the user authority total code corresponding to the user id.
Optionally, the authority table establishing module is further configured to randomly capture prime numbers in a prime number table from 1 to 100, and assign the captured prime numbers to the authority codes according to time sequence established by the authority names; after the prime number is randomly captured each time, whether the captured prime number is repeated with the prime number which is captured before is judged, and when the captured prime number is not repeated, the next prime number is captured.
Specifically, the menu authority establishing module is further configured to set the menu authority total code to a format of a character string with a character length of 20; the user authority establishing module is also used for setting the user authority total code into a format of a character string with the character length of 20.
