Embodiment 1

[0052] Such as figure 1 as shown,

[0053] A method for providing complex webpage applications in a resource-constrained environment. In this embodiment, the operating environment of all interface logic and part of the business logic of the webpage application is transferred from the traditional server to the browser client to realize Reduced performance on servers with CPU-constrained and / or RAM-constrained runtimes.

[0054]In step S110, the running environment of all interface logic of the web application is transferred to the browser client. The interface logic traditionally undertaken by the server includes: initialization of interface components; image loading; jumping, displaying or hiding between different interfaces; changing, displaying or hiding internal components of the interface; and layout changes. In this embodiment, the above-mentioned interface logic is all realized by manipulating the Document Object Model (ie, DOM, which is a standard program interface of...

Embodiment 2

[0064] Such as figure 2 as shown,

[0065] A method for providing complex webpage applications in a resource-constrained environment. This embodiment is improved on the basis of the first embodiment. The main improvement is that in this embodiment, due to the limited ROM storage capacity of the server , the code size of the webpage application plus its server may exceed the available capacity of the memory, and it is necessary to compress the webpage application stored on the server.

[0066] process,

[0067] In step S210, use C language to write the server side of the webpage application program;

[0068] Next, in step S211, the number of program code words is reduced by removing comments, blanks and newlines of the web application program and removing uncalled codes;

[0069] Specifically, deleting comments, blanks and newlines will not affect the execution of the program; by analyzing the calling relationship of each module, remove the code that is not called; then, i...

Abstract

The invention relates to a method and device for providing complex web applications in a resource-constrained environment. The method includes the following steps (1) the operating environment of all the interface logic and part of service logic of the web applications is transferred to a browser client from a traditional server to lower the requirements of the server when CPU processing capacity and / or a RAM in operation are / is constrained; (2) on the premise that executing effect is not affected, the web applications and codes of the server of the web applications are decompressed to lower the requirements of the server when ROM storage capacity is constrained. The method and device for providing the complex web applications in the resource-constrained environment has the advantages that the requirements for the CPU processing capacity and the RAM in operation are substantially lowered; complex interface effect and interaction of a large amount of structural data can be achieved; the requirements of the server for the ROM storage capacity are lowered; more than 99% browser occupancy is covered, and the constraint of only supporting a specific browser (IE in general) caused by the mode that the applications are encapsulated in browser plug-ins is gotten rid of.

Description

technical field [0001] The invention relates to a method and equipment for providing complex web page applications in a resource-limited environment, and belongs to the field of digital information transmission. Background technique [0002] With the development of communication technology and computer technology, more and more users hope to use web browsers to complete various operations and configuration management functions on product equipment. However, due to the limitations of power consumption, size and price, the hardware resources of these devices such as processing power, random access memory (RAM) and read-only memory (ROM) are quite limited. Typical hardware configurations are 300MHz ARM CPU, 32MB RAM and 32MB ROM. Therefore, due to resource constraints, these devices cannot run complex web application servers, or perform poorly when processing complex web page requests. [0003] A web application is an application software that operates using a web browser. I...
