小程序右上角原生菜单自带的分享按钮，默认不可用

 1.创建一个mixin share.js

export default {created() {//#ifdef MP-WEIXINwx.showShareMenu({withShareTicket: true,menus: ['shareAppMessage', 'shareTimeline']});//#endif},
}export default {created() {//#ifdef MP-WEIXINwx.showShareMenu({withShareTicket: true,menus: ["shareAppMessage", "shareTimeline"],});//#endif},onShareAppMessage(res) {// 发送给朋友return {// title: "your title", // imageUrl: "your image",};},onShareTimeline(res) {// 分享到朋友圈return {// title: "your title",// imageUrl: "your image",};},
};

2.全局使用，在 main.js 里面 添加全局的 mixin

import share from './common/share.js'
Vue.mixin(share)

3.成果：所有页面都可以分享
