Webpage optimization method for WKWebView component

Abstract

The invention discloses a webpage optimization method for a WKWebView component, and the method comprises the steps: carrying out the pre-analysis and pre-connection of a domain name through the WKWebView component when an APP is started, and caching resources needed by the APP to a shared space for subsequent webpage access; applying for two global pipeline queues in a jsContext component betweena native layer and a webpage layer, which are respectively used for bidirectional access between the webpage layer and the native layer, so as to realize expansion of native capability; encrypting each message in the native layer and decrypting each massage at a server side, so that the network security performance of a webpage is improved. The native layer is accessed to a webp picture analysislibrary, a picture request is transmitted to the native layer through a global pipeline, and the native layer processes the picture request and returns a picture cache address to the webpage layer, sothat webpage display of a webp picture is realized. According to the method, the webpage loading speed is increased, the network security is improved, the capability of accessing a native operating system by a webpage is improved, and the support for a webp format is increased.

Description

technical field [0001] The invention relates to the field of Internet technologies, and in particular, to a web page optimization method for a WKWebView component. Background technique [0002] Apple has launched a new framework WebKit after iOS8, which provides a WKWebView component that replaces the original UIWebView. This component has the advantages of high stability, low memory usage, and fast rendering speed. It is an official webpage display component recommended by Apple. Although WKWebView has many advantages, it is more closed than the original UIWebView component, and the original optimization strategies such as access interception and cache optimization have all failed. [0003] The WKWebView component is limited by the capabilities of web pages, and most of the usage scenarios are limited to ordinary content display. The native capabilities of the smartphone operating system, such as positioning, accessing the camera, calling, etc., are extremely lacking, and t...

Problems solved by technology

Although WKWebView has many advantages, compared with the original UIWebView component, it is more closed, and the original optimization strategies such as access interception and cache optimization have been invalidated.

[0003] The WKWebView component is limited by the capabilities of the webpage, and most of the usage scenarios are limited to ordinary content display. It lacks support for the native capabilities of the smartphone operating system, such as positioning, accessing the camera, and calling. The functions that can be realized cannot be compared with smartphones. Compared to the native development of the operating system

[0004] In addition, the issue of network security is a very important link in web development. Although the commonly used https protocol can effectively improve the encryption and anti-peeping of network messages, the server cannot verify the authenticity of its messages, and cannot prevent forgery and duplication of request messages. malicious attacks on servers

At the same time, due to the openness of the JavaScript language, it is impossible to perform sensitive and complex encryption processing on messages at the JavaScript language level

[0005] The Webp format is a new image display format introduced by Google. Compared with commonly used jpg, png and other formats, it has a higher compression ratio and can significantly reduce bandwidth consumption. However, the WKWebView component cannot directly support webP images in web pages. show
