1、新建wechatAuth.js文件
const queryString = require('query-string') //应用授权作用域,snsapi_base (不弹出授权页面,直接跳转,只能获取用户openid),snsapi_userinfo (弹出授权页面,可通过openid拿到昵称、性别、所在地。并且,即使在未关注的情况下,只要用户授权,也能获取其信息) const SCOPES = ['snsapi_base', 'snsapi_userinfo'] class VueWechatAuthPlugin { install(Vue, options) { let wechatAuth = this this.setAppId(options.appid) Vue.mixin({ created: function () { this.$wechatAuth = wechatAuth } }) } constructor() { this.appid = null this.redirect_uri = null this.scope = SCOPES[1] this._code = null this._redirect_uri = null } static makeState() { return Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15) } setAppId(appid) { this.appid = appid } set redirect_uri(redirect_uri) { this._redirect_uri = encodeURIComponent(redirect_uri) } get redirect_uri() { return this._redirect_uri } get state() { return localStorage.getItem("wechat_auth:state") } set state(state) { localStorage.setItem("wechat_auth:state", state) } get authUrl() { if (this.appid === null) { throw "appid must not be null" } if (this.redirect_uri === null) { throw "redirect uri must not be null" } this.state = VueWechatAuthPlugin.makeState() return `https://open.weixin.qq.com/connect/oauth3/authorize?appid=${this.appid}&redirect_uri=${this.redirect_uri}&response_type=code&scope=${this.scope}&state=${this.state}#wechat_redirect` } returnFromWechat(redirect_uri) { let parsedUrl = queryString.parse(redirect_uri.split('?')[1]) if (process.env.NODE_ENV === 'development') { // console.log('parsedUrl: ', parsedUrl) this.state = null this._code = parsedUrl.code } else { if (this.state === null) { throw "You did't set state" } if (parsedUrl.state === this.state) { this.state = null this._code = parsedUrl.code } else { this.state = null throw `Wrong state: ${parsedUrl.state}` } } } get code() { if (this._code === null) { throw "Not get the code from wechat server!" } // console.log(this) // console.log('this._code: ' + this._code) let code = this._code this._code = null // console.log('code: ' + code) return code } } const vueWechatAuthPlugin = new VueWechatAuthPlugin() export default vueWechatAuthPlugin
2、main.js中导入
import wechatAuth from './plugins/wechatAuth'//微信登录插件 const queryString = require('query-string'); Vue.use(wechatAuth, {appid: XXXXXXXXX});
3、路由钩子中可以进行相关操作
router.beforeEach((to, from, next) => { if (store.state.loginStatus == 0) { //微信未授权登录跳转到授权登录页面 let url = window.location.href; //解决重复登录url添加重复的code与state问题 let parseUrl = queryString.parse(url.split('?')[1]); let loginUrl; if (parseUrl.code && parseUrl.state) { delete parseUrl.code; delete parseUrl.state; loginUrl = `${url.split('?')[0]}?${queryString.stringify(parseUrl)}`; } else { loginUrl = url; } wechatAuth.redirect_uri = loginUrl; store.dispatch('setLoginStatus', 1); window.location.href = wechatAuth.authUrl } else if (store.state.loginStatus == 1) { try { wechatAuth.returnFromWechat(to.fullPath); } catch (err) { store.dispatch('setLoginStatus', 0) next() } store.dispatch('loginWechatAuth', wechatAuth.code).then((res) => { if (res.status == 1) { store.dispatch('setLoginStatus', 2) } else { store.dispatch('setLoginStatus', 0) } next() }).catch((err) => { next() }) }else { next() } });
