Abstract
The method makes browser window initialization through application program to generate user boundary surface and user input network address. Whether the inputted network address format is correct or not is judged and the server is connected by calling network connection function if the format is correct, otherwise network address should be reinputted. The analytical processing for web page contnet taken from the server is carried out if the connection is normal, otherwise the network address should be reinputted. The analytical processed web page content can be generated to be display page through calling graphic routine program. Since the graphic routine program is added in the method, the user can carry on freely rade signal of boundary surface based on the normal browser to increase some new functions.
Description
Technical field
The present invention relates to a kind of Web browser method that is used for embedded device, belong to technical field of the computer network.
Background technology
Based on the high-end embedded device of (SuSE) Linux OS, as digital TV set-top box, palm PC etc., web browser wherein is an important component part.The IE that Microsoft is arranged that the browsing page method is common in the PC, the Netscape of Netscape " navigator " browser etc., these browsing methods are multiple functional, and are stable, and the interface is beautiful, but it is huge, at least tens, hundreds of million at most, move in embedded device, because the memory capacity of embedded device is less, thereby is unpractical.And,, transplant relatively difficulty because its running environment and the scope of application are relatively harsher for the smaller browser of existing scale.
Summary of the invention
The objective of the invention is for overcoming the weak point of prior art, a kind of Web browser method that is used for embedded device is proposed, bulky at existing browser, be difficult to develop the shortcoming of transplanting, browsing method is improved, in browsing, call the graphic package of bottom, to realize that one-time programming repeatedly uses, satisfy the user to browsing the demand of general webpage.
The Web browser method that is used for embedded device that the present invention proposes may further comprise the steps:
1, makes the browser window initialization by application program, generate user interface;
2, the user imports network address;
3, judge whether the network address form of user input is correct, if correct, then enters next step, otherwise gets back to above-mentioned the 2nd step, waits for that the user re-enters network address;
4, call network contiguous function Connection Service device,, then enter next step if connect normally, otherwise, display page is made mistakes, get back to above-mentioned the 2nd step, wait for that the user re-enters network address;
5, the web page contents from server retrieves is carried out dissection process;
6, by calling the web page contents generation display page of graphic package with dissection process.
In the said method, the network address of user's input is IP address or domain name.
The Web browser method that is used for embedded device that the present invention proposes owing to increased graphic package, therefore is suitable for different users, is convenient to customization.Different users can carry out different customizations according to the needs of oneself, and the various object parser of bottom are transparent to the programmer, the user can redesign the interface on the basis of generic browser fully, add new function, make the integrated level of various systems improve, reduced the programming amount simultaneously greatly.
Description of drawings
Fig. 1 is the FB(flow block) of the inventive method.
Specific implementation method
Browsing method of the present invention as shown in Figure 1, may further comprise the steps:
1, the user want to use browser the time click browser icon, browser program begins to start.
2, the browser application module begins the initialization window then, generates user interface.
3, the user just can import after window generates and want the website that connects, and the network address of input can be IP address or domain name.
4, browser is after receiving user input, if judge earlier that whether correct the network address form of user's input correctly then enter next step, otherwise will get back to previous step, and the wait user re-enters network address.
5, browser calls network contiguous function Connection Service device, if connect normally, will enter next step, otherwise, with the make mistakes page and wait for that the user re-enters network address of demonstration.
6, the parsing module of browser will carry out dissection process to the web page contents of fetching.
7, last browser generates display page with the web page contents of dissection process.Finish after the demonstration, browser will continue to wait for that user's input is to connect new website.
This browsing method is applicable to the embedded device of supporting linux kernel, and its executable file size is 1MB, and the running space that needs is 2MB.The graphical user interface of bottom can be Microwindows or these two kinds of popular graphic models of X-Windows.This browser software is supported HTML4.0, HTTP1.1 and multiple graphical format commonly used, and as BMP, JPEG, static GIF etc.Provide scroll bar can browse the large scale webpage, bookmark is provided, and browser common functions such as advancing, stop, refreshing can normally be visited Chinese and English webpage at present, and can support other double byte ISN according to user's requirement, be the requisite network tool of high-end embedded device.
Because (SuSE) Linux OS can be transplanted on the most chip now, as StrongArm, SH3, SH4, M68000, X86 etc., this software just can play a role on multiple embedded device.
This method has the repertoire of general browser, is suitable for embedded system.The needed storage space of browser can satisfy the requirement of embedded system to hardware fully less than 2M.Therefore just this method can be used in picture palm PC, the embedded device that set-top box etc. link to each other with the Internet as long as revise a little.
Because the resolving of this method has adopted open true form, therefore be convenient to system upgrade.Because existing KDE1.0 only supports HTML3.2, adopt the browsing of website of new standard to have problems for some, if therefore under the situation that the hardware condition of embedded system is permitted, can be upgraded to KDE2.0 (KDE2.0 approximately is 4 times of sizes of KDE1.0), make it to support HTML 4.0 and JavaScript 1.4.Adopt and directly build user interface based on the graphics devices storehouse of bottom graphic user interface, make user interface under the support that breaks away from traditional X-Windows desktop environment, as long as the support of MicroWindows desktop environment is arranged, still can obtain good visual effect.Guaranteed simultaneously and can under X-Windows, can under Micro Windows, move again.
Last browser generates display page with the web page contents of dissection process, and display page is realized by graphic package.Because graphic package and operating system independent, therefore whole user interface and view show that can be transplanted to several operation systems easily gets on.And other parts except user cross section and view demonstration, the C++ MFC that all is to use is realized, and this MFC all is general on most operating systems, so whole browser can be transplanted on the several operation systems easily.
Finish after the demonstration, browser will continue to wait for that user's input is to connect new website.
The shared space of the adhesive linkage that most existing commercial company provides is excessive and can not move on the operating system of embedded device, so need oneself to write an adhesive linkage of simplifying and being suitable for.Particularly, adopted the graphics devices kit that can under the embedded desktop environment of the Microwindows of the X-Windows of PC desktop environment and embedded device, can both move to write an adhesive linkage again.Parsing module to the upper strata still provides identical common interface class like this, comprises figure, character string and generic function class.
