Description
Technical Field
The embodiment of the invention relates to the technical field of browsers, in particular to a page display method and device.
Background
The browser kernel is a core part of the browser and is responsible for explaining the webpage syntax, and determines how the browser displays the content of the webpage, the format information of the webpage and the like. The types of the browser kernels are many, and at present, the common browser kernels mainly include three types: the first type: the Webkit kernel is mainly applied to browsers such as Safari, Chrome, Opera and the like; the second type: the Trident kernel is mainly applied to IE series browsers; in the third category: and the Gecko kernel is mainly applied to a Firefox browser.
Because the different browser kernels interpret the web page writing methods differently, the rendering effect of the same web page in different browsers of the same kernel is different.
At present, service systems inside enterprises are more and more, the association among the service systems is more and more compact, and there is often a case that after one service system is opened by one browser, other service systems need to be visited mutually. When each service system is developed, the supported browser kernels are inconsistent, so that compatibility problems often occur, such as js error, unavailability of a certain function, poor webpage rendering effect and the like. For example, when the service system a accesses the service system B through single sign-on, the service system a is only compatible with the IE11 browser of the Trident kernel, and the service system B is only compatible with the chrome browser of the Webkit kernel, so that the compatibility problem occurs, which causes some functions of the service system to be abnormal, and the user experience to be poor.
At present, there are two main methods for solving the compatibility problem: the first solution is for the user to install enough browsers on the local client and remember the best browser for each service system. And the other is that the development team debugs the compatibility among the browsers and the kernels thereof one by one according to different browsers.
However, in the first solution, because the sessions of different browsers are different, the user needs to log in and access different browsers for multiple times, which greatly affects the convenience of the user for accessing the service system, and the user experience is poor. In the second solution, there is a problem that development and maintenance costs are high.
Therefore, a solution is needed to provide a solution that can improve the user experience and reduce the development cost while solving the compatibility problem when the user accesses different service systems of the enterprise.

s110: and extracting page attributes from the page to be displayed.
The page display method provided by the embodiment of the invention is suitable for a scene that a user sends a webpage request through the browser, and the browser displays the page to be displayed after receiving the page to be displayed returned by the target service system.
The execution main body of the page display method provided by the embodiment of the invention can be specifically a browser with a kernel adaptation function; or a device connected to a browser.
In practical applications, the web page request sent by the browser may specifically be an http (hyper text transfer protocol) message request; correspondingly, the page to be displayed returned by the target service system may specifically be an http page. The target service system refers to a service system which is pre-accessed by a user; the user can directly access the target service system or jump to the target service system through the currently accessed service system.
In the embodiment of the present invention, the page attribute extracted from the page to be displayed may include at least one of the following: js (javascript ), css (cascading style sheet), and meta (meta) attributes.
In the embodiment of the present invention, the extraction of js, the extraction of css, and the extraction of meta attribute may adopt technical means commonly used by those skilled in the art, and are not described in detail herein.

Specifically, the extracted page attribute may be subjected to keyword extraction, and a keyword set corresponding to the page to be displayed is generated according to the extracted keyword.
Then, for each browser kernel, according to a Bayesian algorithm preset in the kernel selection model and a kernel selection model parameter corresponding to the browser kernel, calculating the probability of rendering the kernel by taking the browser kernel as a target when the keyword set appears, and taking the probability as the matching degree between the browser kernel and the page to be displayed. The kernel selection model parameter corresponding to the browser kernel is specifically the occurrence probability of each keyword when the browser kernel is taken as a target to render the kernel.
The rendering display effect of the browser kernel on the page to be displayed is best when the probability that the browser kernel is taken as a target rendering kernel is larger when the keyword set corresponding to the page to be displayed appears is considered.

And calculating the occurrence probability of a keyword set according to the formula (2) and the occurrence probability of each browser kernel.
Then, according to the formula (1), the occurrence probability of each browser core, the occurrence probability of the keyword set when rendering the core by taking each browser core as a target and the occurrence probability of the keyword set, the probability of rendering the core by taking different browser cores as the target when the keyword set occurs is respectively calculated.
In this way, for each browser kernel, the probability of rendering the kernel with the browser kernel as a target when the keyword set appears can be used as the matching degree between the browser kernel and the page to be displayed. And finally, selecting the browser kernel with the highest matching degree as a target rendering kernel corresponding to the page to be displayed.
