103. and decoding the code file into corresponding web resources based on a pre-constructed decoding system, and feeding back the web resources to the client.
Fig. 2 is a system flowchart provided by the embodiment of the present invention, and as shown in fig. 2, when a storage space is insufficient, the embodiment of the present invention encodes and compresses a web file by using an encoding algorithm, stores more richer web page files in a fixed ROM, and further converts the encoded file into a C code, so as to get rid of dependency on a file system.
Specifically, in step 101, the embodiment of the present invention performs transcoding on the written web file, then performs C-transcoding in step 102, and finally performs decoding in step 103, where step 101 and step 102 are completed in the compiling environment, and step 103 is completed in the target device.
According to the webpage compression and storage method and system based on the ROM, more and richer web resources can be stored through the method, hardware does not need to be changed, and the web resources are coded, so that the method is also suitable for equipment without a file system.
On the basis of the above embodiment, the method further includes:
and preprocessing the web file and reserving a code part.
On the basis of the above embodiment, preprocessing the web file, and reserving a code portion includes:
and eliminating all line feed, blank spaces and comments of the text document in the web file, and only reserving a code part needing machine execution.
Specifically, the embodiment of the invention preprocesses the written web file, and mainly aims at text files such as html, CSS, js and the like. In the preprocessing stage, all line feed, blank spaces, comments and the like in the text documents are removed in a unified way, so that people can conveniently view the symbols and texts of the codes, and only the most core code parts needing machine execution are reserved.
On the basis of the above embodiment, the transcoding web files based on a pre-programmed coding table to obtain a coding sequence of each web file includes:
the code table is made by counting the occurrence probability of each character in the web file in advance to define the code sequence of the character, wherein the higher the occurrence probability of the character is, the shorter the code sequence is.
In particular, web documents are typically described in terms of codes such as utf-8, unicode, or gbk, with each character corresponding to a fixed length code sequence, and the code sequences are stored in the storage medium. For a written web file, the probability of each character appearing is different, and if each character is coded and stored according to a certain length, space is wasted. Based on this, the probability of each character appearing in these documents can be counted in advance, the coding sequence of these characters is defined, a coding table is compiled, and the principle is as follows: the higher the probability of occurrence of a character, the shorter its code sequence. After the web files are coded in this way, the web files are compressed, and the coded sequence of each web file can be temporarily stored in the file as a subsequent input.
On the basis of the above embodiment, the converting the code sequence into a code file written in a programming language includes:
storing binary numbers corresponding to the coding sequences by using arrays, wherein each web file corresponds to one binary number array;
the binary array is generated as a code file.
Specifically, the above-described encoded file is converted. The coding sequence in the coding file is a continuous binary number, in the programming language, the binary number can be stored by using an array, each web file corresponds to an array, and finally a code file is formed. The code file can be compiled with the web server program, so that the web file becomes a part of the executive program and is stored in the ROM, and the dependency on a file system is eliminated.
On the basis of the above embodiment, the decoding system based on pre-construction decodes the code file into a corresponding web resource, and feeds back the web resource to the client, and includes:
traversing the coding array to find corresponding web resources;
and restoring the binary sequence in the array into characters based on the pre-constructed decoding system, replying the characters to the web server, and finally feeding back the characters to the client.
Specifically, the embodiment of the present invention constructs a decoding system, and after receiving a request from a client, a web server sends a corresponding request to the decoding system, and the decoding system finds a corresponding web resource by traversing a coding array, decodes the web resource by using a coding table, reduces a binary sequence in the array into a character, replies the character to the web server, and finally feeds the character back to the client.
