Abstract

The invention discloses a file storage method, which comprises the following steps: s1, acquiring an operation user name K of a current uploading file, and defining a value function b (K) of the operation user name K: b (K) =k mod M; taking the operation result of the value function b (K) as the name of the primary directory; s2, acquiring the current year and month Y, and calculating a value function b (Y) of the current year and month Y: b (Y) =y mod M, and the operation result is taken as the name of the secondary directory; s3, acquiring a file step variable value n set by a system; s4, acquiring a file name Z of the uploaded file, and calculating a value function P (Z) of the file name Z; s5, mixing the P (Z) value obtained in S4 with 2 n 1, performing bitwise AND operation to obtain the name of the three-level catalogue; s6, storing the file under the corresponding catalogue. The invention stores the user name, date and file name in the three-level catalogue respectively, can solve the problem that too many files are in the same folder when the files are uploaded and stored in the B/S architecture, can search the files in various modes, and improves the reading efficiency and performance of the files.

Description

File storage method
Technical Field
The invention belongs to the technical field of file storage, and particularly relates to a file storage method.
Background
In the B/S architecture model, the end user creates a folder on a server (typically a file server) by user action and then saves the file under the folder when saving the file.
Along with the increase of the service time of the system or the frequent file operation of a user, excessive files under a certain folder can finally appear, so that the searching is inconvenient and the reading performance of the files is affected.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a file storage method which can store a user name, a date and a file name in a three-level directory respectively, search files in various modes and improve the reading efficiency and performance of the files.
The aim of the invention is realized by the following technical scheme: a method of storing a file, comprising the steps of:
s1, acquiring an operation user name K of a current uploading file, and defining a value function b (K) of the operation user name K:
b(K)＝K mod M
wherein mod is a remainder function, and M is any prime number;
taking the operation result of the value function b (K) as the name of the primary directory;
s2, acquiring the current date Y, and calculating a valued function b (Y) of the current date Y:
b(Y)＝Y mod M
the operation result is used as the name of the secondary catalog;
s3, acquiring a file step variable value n set by a system;
s4, acquiring a file name Z of the uploaded file, and calculating a value function P (Z) of the file name Z:
wherein W is the size of the computer word,f function is a rounding function;
s5, mixing the P (Z) value obtained in S4 with 2 n 1, carrying out bitwise AND operation according to the bits to obtain the names of the three-level catalogs;
and S6, storing the user name, the date and the file name under the corresponding catalogs respectively.
The beneficial effects of the invention are as follows: the invention stores the user name, date and file name in the three-level catalogue respectively, can solve the problem that too many files are in the same folder when the files are uploaded and stored in the B/S architecture, can search the files in various modes, and improves the reading efficiency and performance of the files.
Detailed Description
The technical scheme of the invention is further described below.
The invention discloses a file storage method, which comprises the following steps:
s1, acquiring an operation user name K of a current uploading file, and defining a value function b (K) of the operation user name K:
b(K)＝K mod M
wherein mod is a remainder function, and M is any prime number;
taking the operation result of the value function b (K) as the name of the primary directory;
s2, acquiring the current date Y (generally adopting a year and month format yyyy-MM, for example 2109-12), and calculating a value function b (Y):
b(Y)＝Y mod M
the operation result is used as the name of the secondary catalog;
s3, acquiring a file step variable value n set by a system;
s4, acquiring a file name Z of the uploaded file, wherein the file name Z comprises a suffix name such as (example. Zip); calculating a valued function P (Z):
wherein W is the size of the computer word,f function is a rounding function;
s5, carrying out bit-wise AND operation on the P (Z) value obtained in the S4 and 2n-1 (converting the obtained value into a 2-system number, then carrying out bit-wise AND operation) to obtain the name of the three-level directory;
s6, finally, the files are evenly distributed into three-level catalogues, and the maximum number of the three-level catalogues is (2 n -1) the uploaded original file is directly saved in a tertiary directory, and then the user name, date and file name are saved under the corresponding directory, respectively.
Those of ordinary skill in the art will recognize that the embodiments described herein are for the purpose of aiding the reader in understanding the principles of the present invention and should be understood that the scope of the invention is not limited to such specific statements and embodiments. Those of ordinary skill in the art can make various other specific modifications and combinations from the teachings of the present disclosure without departing from the spirit thereof, and such modifications and combinations remain within the scope of the present disclosure.
