微信小程序全局开启分享朋友或者朋友圈

1.在app.js定义方法

overShare: function () {

//监听路由切换

wx.onAppRoute(function (res) {

let pages = getCurrentPages(),

view = pages[pages.length - 1]

if (view) {

wx.showShareMenu({

withShareTicket: true,

menus: ['shareAppMessage', 'shareTimeline']

})

}

})

},

 

2.在onLaunch钩子中调用方法

onLaunch: function () {

　　this.overShare()

}
