element-ui 本地化使用教程详解
(编辑:jimmy 日期: 2024/11/27 浏览:3 次 )
起因:
用 element-ui 时,本人是没有安装其它环境,而是直接用链接引入,这个带来的问题是,每次打开网页都很慢,于是想本地化,但是发现只是下载两个引入的 js 和 css 是不够的,很多功能会无法使用,打开 DevTools 发现是还有别的资源本地没有。
再次前往官网,找到下载页面,结果发现并没有给直接的下载链接。。没办法了,自己写个脚本来下载。最后成功离线化。
下载后在 html 中引入:
<!--<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">--> <link rel="stylesheet" href="element-ui/lib/theme-chalk/index.css" rel="external nofollow" > <!--<script src="/UploadFiles/2021-04-02/index.js">下载脚本:
临时起意做的,代码里面可能会有些瑕疵,但是不影响使用,本人已经成功下载并使用。
路径可以自己更改,注意不要从 Windows 资源管理器复制,Linux 系统当我没说。package com.ycr; import java.io.File; import java.io.FileOutputStream; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import java.nio.charset.StandardCharsets; import java.util.ArrayList; public class Main { static String fileP = "C:\\Users\\YCR\\Desktop\\element-ui\\"; // 不要从资源管理器复制,有的字符会有问题,导致无法创建文件 static String urlP = "https://unpkg.com/browse/element-ui@2.12.0/"; static String urlF = "https://unpkg.com/element-ui@2.12.0/"; public static void main(String[] args){ try { GetPage(""); } catch (Exception e) { e.printStackTrace(); } } static void GetPage(String after) throws Exception { System.out.println(urlP + after); new File(fileP + after).mkdir(); HttpURLConnection http = (HttpURLConnection) (new URL(urlP + after)).openConnection(); http.setRequestMethod("GET"); http.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3562.0 Safari/537.36"); http.connect(); if(http.getResponseCode() == 200) { InputStream inputStream = http.getInputStream(); byte [] buffer = new byte[1024]; ArrayList<byte []> byteList = new ArrayList<>(); ArrayList<Integer> byteLength = new ArrayList<>(); int length; int totalLength = 0; while( (length = inputStream.read(buffer)) != -1 ) { byteList.add(buffer); byteLength.add(length); totalLength += length; buffer = new byte[1024]; } http.disconnect(); byte [] all; all = new byte[totalLength]; totalLength = 0; while(byteList.size() != 0) { System.arraycopy(byteList.get(0), 0, all, totalLength, byteLength.get(0)); totalLength += byteLength.get(0); byteList.remove(0); byteLength.remove(0); } String content = new String(all, StandardCharsets.UTF_8); all = null; content = content.split("tbody")[1]; String [] us = content.split("href=\""); for(int i = 1; i < us.length; i ++) { String href = us[i].split("\"", 2)[0]; if(href.equals("../")) { continue; } if(href.charAt(href.length() - 1) == '/') { GetPage(after + href); } else { GetFile(after + href); } } } else { GetPage(after); } } static void GetFile(String url) throws Exception{ System.out.println(url); HttpURLConnection http; http = (HttpURLConnection) (new URL(urlF + url)).openConnection(); http.setRequestMethod("GET"); http.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3562.0 Safari/537.36"); http.connect(); if(http.getResponseCode() == 200) { InputStream inputStream = http.getInputStream(); byte [] buffer = new byte[1024]; ArrayList<byte []> byteList = new ArrayList<>(); ArrayList<Integer> byteLength = new ArrayList<>(); int length; int totalLength = 0; while( (length = inputStream.read(buffer)) != -1 ) { byteList.add(buffer); byteLength.add(length); totalLength += length; buffer = new byte[1024]; } http.disconnect(); byte [] all; all = new byte[totalLength]; totalLength = 0; while(byteList.size() != 0) { System.arraycopy(byteList.get(0), 0, all, totalLength, byteLength.get(0)); totalLength += byteLength.get(0); byteList.remove(0); byteLength.remove(0); } File f = new File(fileP + url.replaceAll("/", "\\\\")); f.createNewFile(); FileOutputStream fos = new FileOutputStream(f, false); fos.write(all); fos.flush(); fos.close(); } else { GetFile(url); } } }以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
