Vue3+Ts封装Axios及Vue的Proxy配置 一、开箱即用的axios封装：Vue3+ts作者：诸葛小愚链接：https://juejin.cn/post/7107047280133275678来源：稀土掘金著作权归作者所有。商业转载请联系作者获得授权，非商业转载请注明出处。新建index.ts文件：需要定义请求返回的数据格式，这个可以和服务端约定好数据格式需要定义axios的配置信息，用于在创建axios实例时传入请求拦截器，前端所有的接口请求都会先达到请求拦截器，我们可以在此添加请求头信息响应拦截器，服务端返回的数据会先达到响应拦截器，我们可以处理服务端的响应信息。如果是报错，就处理常见的报错；如果是成功，就返回数据封装常用的get、put、post、delete接口方法封装axiosimport axios, {AxiosInstance, AxiosError, AxiosRequestConfig, AxiosResponse} from 'axios' import {ElMessage} from 'element-plus' // 数据返回的接口 // 定义请求响应参数，不含data interface Result { code: number; msg: string } // 请求响应参数，包含data interface ResultData<T = any> extends Result { data?: T; } const URL: string = '' enum RequestEnums { TIMEOUT = 20000, OVERDUE = 600, // 登录失效 FAIL = 999, // 请求失败 SUCCESS = 200, // 请求成功 } const config = { // 默认地址 baseURL: URL as string, // 设置超时时间 timeout: RequestEnums.TIMEOUT as number, // 跨域时候允许携带凭证 withCredentials: true } class RequestHttp { // 定义成员变量并指定类型 service: AxiosInstance; public constructor(config: AxiosRequestConfig) { // 实例化axios this.service = axios.create(config); /** * 请求拦截器 * 客户端发送请求 -> [请求拦截器] -> 服务器 * token校验(JWT) : 接受服务器返回的token,存储到vuex/pinia/本地储存当中 */ this.service.interceptors.request.use( (config: AxiosRequestConfig) => { const token = localStorage.getItem('token') || ''; return { ...config, headers: { 'x-access-token': token, // 请求头中携带token信息 } } }, (error: AxiosError) => { // 请求报错 Promise.reject(error) } ) /** * 响应拦截器 * 服务器换返回信息 -> [拦截统一处理] -> 客户端JS获取到信息 */ this.service.interceptors.response.use( (response: AxiosResponse) => { const {data, config} = response; // 解构 if (data.code === RequestEnums.OVERDUE) { // 登录信息失效，应跳转到登录页面，并清空本地的token localStorage.setItem('token', ''); // router.replace({ // path: '/login' // }) return Promise.reject(data); } // 全局错误信息拦截（防止下载文件得时候返回数据流，没有code，直接报错） if (data.code && data.code !== RequestEnums.SUCCESS) { ElMessage.error(data); // 此处也可以使用组件提示报错信息 return Promise.reject(data) } return data; }, (error: AxiosError) => { const {response} = error; if (response) { this.handleCode(response.status) } if (!window.navigator.onLine) { ElMessage.error('网络连接失败'); // 可以跳转到错误页面，也可以不做操作 // return router.replace({ // path: '/404' // }); } } ) } handleCode(code: number):void { switch(code) { case 401: ElMessage.error('登录失败，请重新登录'); break; default: ElMessage.error('请求失败'); break; } } // 常用方法封装 get<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.get(url, {params}); } post<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.post(url, params); } put<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.put(url, params); } delete<T>(url: string, params?: object): Promise<ResultData<T>> { return this.service.delete(url, {params}); } } // 导出一个实例对象 export default new RequestHttp(config);实际使用在使用时，我们需要在API文档中导入index.ts，会自动创建一个axios实例。我们在同目录下，新建一个login.tsimport axios from './' namespace Login { // 用户登录表单 export interface LoginReqForm { username: string; password: string; } // 登录成功后返回的token export interface LoginResData { token: string; } } // 用户登录 export const login = (params: Login.LoginReqForm) => { // 返回的数据格式可以和服务端约定 return axios.post<Login.LoginResData>('/user/login', params); }API接口也定义好了，再来一个页面简单试试：<script setup> import { reactive } from 'vue'; import {login} from '@/api/login.js' const loginForm = reactive({ username: '', password: '' }) const Login = async () => { const data = await login(loginForm) console.log(data); } </script> <template> <input v-model="loginForm.username" /> <input v-model="loginForm.password" type="password" /> <button @click="Login">登录</button> </template>二、Vue通过Proxy访问不同端口的API后台API使用Springboot开发,部署端口为81251.Vue项目根目录创建vue.config.jsmodule.exports = { devServer: { open: true, host: "127.0.0.1", port: 7123, hot: true, proxy: { "/api": { target: "http://localhost:8125", // 代理地址，这里设置的地址会代替axios中设置的baseURL changeOrigin: true, // 是否跨域 ws: false, // 如果要代理 websockets，配置这个参数 pathRewrite: { "^/api": "", }, }, }, }, };2.示例请求apis/index.ts... const URL = "/api"; ...apis/register.ts... // 用户注册 export const register = (params: RegisterReqForm) => { return axios.post<number>("/user/register", params); }; ...pages/login/Login.ts... async handleRegisterSubmit() { const data = await register(this.registerForm); message.success("用户注册成功"); }, ...根据如上代码可得请求地址为:/api/user/register,并没有host代理后的地址为:http://127.0.0.1:8125/user/register这样就实现前端127.0.0.1:7123代理请求访问127.0.0.1:8125引用1.开箱即用的axios封装：Vue3+ts:https://juejin.cn/post/7107047280133275678#heading-22.Proxy error: Could not proxy request... 问题解决:https://blog.csdn.net/ymiandi/article/details/125674056

Java-微信公众号实现网站登录功能 序言微信登录常见方式平常大家见到过最多的扫码登录应该是 开放平台网页登录 大概形式就是：点击微信登录后会出现一个黑页面，页面中有一个二维码，扫码后可以自动获取用户信息然后登录，但是这种方式需要申请开放平台比较麻烦。如图利于推广方式另外一种扫码登录方式只需要一个微信服务号就行，大概流程是：点击微信登录，网站自己弹出一个二维码、扫描二维码后弹出公众号的关注界面、只要一关注公众号网站自动登录、第二次扫描登录的时候网站直接登录，这种扫码登录的方式个人觉得非常利于推广公众号。流程如下：一、获取二维码二、前端轮询接口,查看扫码情况未扫描：扫描成功：三、扫描二维码方式一：利于推广方式基本流程使用微信扫码登录 我们肯定要先来了解一下扫码登录的基本流程啦前端首先向服务端发送一个请求，用来获取二维码的url和唯一随机数（用UUID即可，这个随机数可以理解为这个二维码的key值，一一对应，所以尽量要用唯一的）同时服务端要记录这条随机数（存redis和其他数据库均可，找个地方记录下来）前端自从收到二维码和随机数后，展示二维码，并轮询一个检查二维码状态的接口（用来判断用户是否扫码并确认）很关键的一步客户扫码并确认后，会回调给服务端一个请求，服务端就能拿到对应的二维码的key（之前产生的随机数）前端轮询中 发现二维码状态值变为用户扫码已确认的值后，向后端发送业务请求（登录。。。。）前提准备导入依赖 <!-- 对接微信登录 开始 --> <dependency> <groupId>com.github.binarywang</groupId> <artifactId>weixin-java-mp</artifactId> <version>4.3.8.B</version> </dependency> <!-- 对接微信登录 结束 --> <!-- 读取配置文件 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency> <!-- 网络请求框架 --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> </dependency> <!-- fast json --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>2.0.10</version> </dependency> <!-- END fast json -->网络请求工具类util/HttpClientUtil.javapublic class HttpClientUtil { public static String doGet(String url, Map<String, String> param) { // 创建Httpclient对象 CloseableHttpClient httpclient = HttpClients.createDefault();

使用Nginx反向代理接入欣赏小姐姐视频站点 前言最近网上冲浪发现了这种欣赏小姐姐的视频站点 ::(你懂的) ，于是想整一个集成到blog里。源站点： 欣赏小姐姐：https://xjiejie.vip/ 成果展示: 欣赏小姐姐：https://www.lisok.cn/online-tiktok.html1.先抓包拿接口😋 对方的反扒意识蛮强的 1.屏蔽了页面上的右键 2.F12打开开发者工具，页面会自动关闭 3.若可以成功打开开发者工具，那么页面在请求数据的时候还会再次检测，若被发现页面会自动关闭。于是干脆放弃用开发者工具了,直接上Fiddler成功拿到接口:URL:https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php Param: # 随机值,防止懒请求： t:xxx Header: # 模拟请求的过程中发现有防盗链,校验Referer请求头 Referer:https://xjiejie.vip/ 2.页面请求博客的网络请求用的JQuery,那请求就由Ajax负责：index.html$(".getUrl").click(function () { let url = "https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php?t=" + Math.random(); $.ajax({ url: url, type: "GET", dataType: "json", success: function (data) { console.log(data); $("#video").attr("src", data.playurl); }, }); });遇到了跨域问题,意料之中,这肯定不能让对方服务器去加响应头,只得我们自己去做一个代理访问。3.PHP代理流程：由原来的前端直接访问对方服务器 变成了 前端访问自己的代理PHP文件，再由PHP去向对方服务器发起请求返回结果。proc.php<?php // 对方的响应有gzip压缩，需要解压缩 function gunzip($zipped) { $offset = 0; if (substr($zipped, 0, 2) == "\x1f\x8b") $offset = 2; if (substr($zipped, $offset, 1) == "\x08") { return gzinflate(substr($zipped, $offset + 8)); } return "Unknown Format"; } // 发起网络请求 $url = 'https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php?t=' . time(); // 发起GET请求 $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 设置请求头 curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type: application/json', 'Accept: application/json', 'Referer: https://xjiejie.vip/', 'Accept-Encoding: gzip, deflate, br', )); // 关闭ssl curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLINFO_HEADER_OUT, 0); curl_setopt($ch, CURLOPT_HEADER, 0); $output = curl_exec($ch); // 若有错误，则抛出异常 if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); exit; } curl_close($ch); // 输出结果 $arr = []; // 获取请求头的Referer $arr = json_decode(gunzip($output), true); $arr['referer'] = $_SERVER['HTTP_REFERER']; $arr['host'] = $_SERVER['HTTP_HOST']; // 输出json header('Content-Type: application/json'); echo json_encode($arr);对应的前端的请求路径也要修改index.htmllet url = "/proc.php" + Math.random();4.Nginx代理最近刚开始学习Nginx,边查资料边测试，实现了这个功能4.1 编写配置文件直接在网站的配置文件中做如下修改：lisok.cn.... location /xjiejie/video/ { proxy_pass https://xjiejie.vip/zb_users/theme/lanyexvideo/include/video.php; proxy_set_header Referer "https://xjiejie.vip/"; proxy_set_header Content-Type "application/json"; proxy_set_header Accept-Encoding "gzip, deflate, br"; proxy_set_header User-Agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36"; proxy_set_header Accept "application/json"; proxy_set_header Host "xjiejie.vip"; } location / { # ！！！原先下三行的内容是没有在 location / 中的！！！ #REWRITE-START URL重写规则引用,修改后将导致面板设置的伪静态规则失效 include /www/server/panel/vhost/rewrite/lisok.cn.conf; #REWRITE-END } ....index.htmllet url = "/xjiejie/video?t=" + Math.random(); $.ajax({ url: url, type: "GET", dataType: "json", success: function (data) { console.log(data); $("#video").attr("src", data.playurl); }, }); });更新:2022.9.8 更新接口今天访问的时候发现不能播放视频了,查看接口发现对方更换了域名nginx配置文件也进行同步更新即可 location /xjiejie/video { proxy_pass https://xjiejie.co/zb_users/theme/lanyexvideo/include/video.php; proxy_set_header Referer "https://xjiejie.co/"; proxy_set_header Content-Type "application/json"; proxy_set_header Accept-Encoding "gzip, deflate, br"; proxy_set_header User-Agent "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36"; proxy_set_header Accept "application/json"; proxy_set_header Host "xjiejie.co"; }5.注意事项PHPStudy集成的是Nginx v1.15.11，这版本使用中会有问题,即使修改了Referer后，反向代理访问对方的站点还是会返回404,后面升级到Nginx v1.16.1就好了。typecho会有伪静态的配置,若先加载的伪静态配置会导致访问接口时候返回页面未找到的404错误，所以nginx的配置项要先于伪静态的配置项。

Selenium破解学习通倍速限制 前言学习通的某些课程会有限制播放速度的功能，不仅播放器没有倍速的播放选项，甚至你通过代码修改播放器的速度也会被监听从而被重置播放器的速度。js修改原先尝试过setInterval设置定时器不断的去修改播放器速度,先不说优雅与否，反正是没有用的，每次修改速度，视频都会被暂停，速度也被重置。后面去油猴找了一个插件参考,扒下来了这段破解倍速的代码：{tabs}{tabs-pane label="代码"}(function () { 'use strict'; console.log(window.location.href) function hack() { if (typeof videojs !== "undefined" && typeof Ext !== "undefined") { Ext.define("ans.VideoJs", { override: "ans.VideoJs", constructor: function (b) { b = b || {}; const e = this; e.addEvents(["seekstart"]); e.mixins.observable.constructor.call(e, b); const c = videojs( b.videojs, e.params2VideoOpt(b.params), function () { } ); Ext.fly(b.videojs).on("contextmenu", function (f) { f.preventDefault(); }); Ext.fly(b.videojs).on("keydown", function (f) { if ( f.keyCode === 32 || f.keyCode === 37 || f.keyCode === 39 || f.keyCode === 107 ) { f.preventDefault(); } }); if (c.videoJsResolutionSwitcher) { c.on("resolutionchange", function () { const g = c.currentResolution(); const f = g.sources ? g.sources[0].res : false; Ext.setCookie("resolution", f); }); } }, }); } } if (window.location.href.indexOf('/ananas/modules/video') > -1) { try { hack(); window.document.addEventListener("readystatechange", hack); window.addEventListener("load", hack); } catch (e) { console.error(e.message); } } })();{/tabs-pane}{tabs-pane label="解释"}hack(); window.document.addEventListener("readystatechange", hack); window.addEventListener("load", hack);关键代码是上面这三行,更关键的是执行时机视频播放区域是位于页面的iframe中,/ananas/modules/video就是这个iframe的链接的一部分执行时间:iframe加载时执行,且先于该页面的其他js脚本,一旦页面加载完毕,再去执行代码就没有作用了。{/tabs-pane}{/tabs}破解完之后,再去执行$('video')[0].playbackRate = 16，就发现不会被重置倍速了。应用在Selenium效果：原理就是注入上一节提到的Js# chrome.execute_cdp_cmd会在所有页面加载前进行执行,先于页面自带的Js # 这段压缩过的Js里有判断Url是否为视频页面的逻辑 chrome.execute_cdp_cmd('Page.addScriptToEvaluateOnNewDocument', { 'source': 'function hack(){if(typeof videojs!=="undefined"&&typeof Ext!=="undefined"){Ext.define("ans.VideoJs",{override:"ans.VideoJs",constructor:function(b){b=b||{};const e=this;e.addEvents(["seekstart"]);e.mixins.observable.constructor.call(e,b);const c=videojs(b.videojs,e.params2VideoOpt(b.params),function(){});Ext.fly(b.videojs).on("contextmenu",function(f){f.preventDefault()});Ext.fly(b.videojs).on("keydown",function(f){if(f.keyCode===32||f.keyCode===37||f.keyCode===39||f.keyCode===107){f.preventDefault()}});if(c.videoJsResolutionSwitcher){c.on("resolutionchange",function(){const g=c.currentResolution();const f=g.sources?g.sources[0].res:false;Ext.setCookie("resolution",f)})}},})}}if(window.location.href.indexOf("/ananas/modules/video")>-1){try{hack();window.document.addEventListener("readystatechange",hack);window.addEventListener("load",hack)}catch(e){console.error(e.message)}};'})注意：chrome.execute_script("xxx")的执行是在页面的Js都加载完毕时才会执行，所以使用这个来执行脚本 此处并不适用。参考1.Selenium: How to Inject/execute a Javascript in to a Page before loading/executing any other scripts of the page? : https://stackoverflow.com/questions/31354352/selenium-how-to-inject-execute-a-javascript-in-to-a-page-before-loading-executi 2.OCS网课助手: https://github.com/ocsjs/ocsjs

vue开发-组件的继承与扩展 1.前言在展示数据的时候 没有用饿了么UI，上github找了一个 vuejs-paginate：https://github.com/lokyoung/vuejs-paginate 使用中发现设置初始页码的属性已经被废弃..NameTypeDescriptioninitial-pageNumber(Deprecated after v2.0.0)The index of initial page which selected. default: 0看到issues里有人有同样的问题,并指出内部有一个属性 是指向页码,于是通过vue-tools看了一下 果真有2.开始整活太久没用了 啥都忘光了(可能本来就不会找我辉哥请教了一番，指点我通过继承来扩展初始页码设置的功能并丢给我一个b站链接： 利用继承修改vue组件，解决el-table中max-height为比例值的滚动问题：https://www.bilibili.com/video/BV1BS4y1m7MR 虽然问题场景不同嘛 但是继承的步骤是一样滴，建议从9分钟开始看正片。2.1 继承组件先创建后组件 并继承自目标组件,内部采用prop 进行父子通信<script> import Paginate from "vuejs-paginate"; export default { extends: Paginate, props: { message: { type: Number, default: 1 } }, data: function () { return { innerValue: this.message }; }, } </script> <style scoped> </style>哦哦哦..别忘了 main.js 中把原先引入的给替换注释掉// import Paginate from 'vuejs-paginate' import MyPaginate from "@/components/MyPaginate"; // 使用分页组件 Vue.use(MyPaginate)2.2 父组件修改template中:<MyPaginate :page-count="pageCount" :click-handler="paginationClickHandler" :prev-text="'Prev'" :message="page" :next-text="'Next'"> </MyPaginate>script中:import 'font-awesome/css/font-awesome.min.css' import MyPaginate from './MyPaginate' export default { name: "WebCommonVideoListContent", components: { MyPaginate }, data() { return { latest: {}, title: '', type: '0', page: 1, pageSize: 40, total: 0, pageCount: 1 } }, methods: { getData() { this.$http.get(this.type === '1' ? '/v1' : 'v2', { params: { page: this.page, pageSize: this.pageSize } }).then(({data}) => { if (data.code === 200) { this.latest = data.data.data this.total = data.data.total // 向上取整 this.pageCount = Math.ceil(this.total / this.pageSize) } else { this.latest = {} alert('获取最新更新失败') } }) }, paginationClickHandler(page) { this.$router.push({name: 'votype', params: {type: this.type + '-' + page}}) } } }然后就ok ::(哈哈)
