微信小程序通过什么函数发包

函数写在util.js页面

function formatTime(date) {

var year = date.getFullYear()

var month = date.getMonth() + 1

var day = date.getDate()

var hour = date.getHours()

var minute = date.getMinutes()

var second = date.getSeconds()

return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')

}

function formatNumber(n) {

n = n.toString()

return n[1] ? n : '0' + n

}

module.exports = {

formatTime: formatTime,

}

使用函数

二、使用相同页面的函数

get_productInformation: function () {

。。。。

},

getZones:function(){

this.get_productInformation

},

三、使用app.js内定义的函数

app.js代码

//app.js

App({

onLaunch: function() {

//调用API从本地缓存中获取数据

var logs = wx.getStorageSync('logs') || []

logs.unshift(Date.now())

wx.setStorageSync('logs', logs)

},

get_a_test:function(){

console.log('this is a test')

},

getUserInfo: function(cb) {

var that = this

if (this.globalData.userInfo) {

typeof cb == "function" &&cb(this.globalData.userInfo)

} else {

//调用登录接口

wx.getUserInfo({

withCredentials: false,

success: function(res) {

that.globalData.userInfo = res.userInfo

typeof cb == "function" &&cb(that.globalData.userInfo)

}

})

}

},

globalData: {

userInfo: null,

college_change:false

}

})

在其他页面中使用

微信小程序的登录获取用户信息，是通过微信d出窗口，用户可点击允许 和拒绝两个按钮，点击允许，则获取用户信息登录成功，若点击拒绝，则获取失败，可通过二次请求调用d起获取用户信息窗口。

具体代码如下：

//app.js

App({

onLaunch: function () {

//调用API从本地缓存中获取数据

var logs = wx.getStorageSync('logs') || []

logs.unshift(Date.now())

wx.setStorageSync('logs', logs)

console.log('logs',logs)

},

getUserInfo:function(cb){

var that = this

//调用登录接口

function getOpenid(backMsg){

that.globalData.userInfo = backMsg.userInfo

that.globalData.encryptedData = backMsg.encryptedData

that.globalData.iv = backMsg.iv

that.globalData.login = true

console.log(that.globalData.code)

wx.request({

url:that.localUrl+'Login/sendCodeLogin',

data:{

code:that.globalData.code,

encryptedData: backMsg.encryptedData,

iv:backMsg.iv

},

success:function(openData){

console.log('返回openid',openData,openData.data)

if(openData.data.code==1001){

that.globalData.openid = openData.data.data.openid

wx.setStorageSync('openid',that.globalData.openid)

wx.setStorageSync('userInfo',that.globalData.userInfo)

wx.setStorageSync('isManager', openData.data.data.isManager)

wx.showToast({

title: '登录成功',

icon: 'success',

duration: 500

})

typeof cb == "function" &&cb(that.globalData.userInfo)

}else{

wx.showLoading({

title: '登录失败'

})

setTimeout(function () {

wx.hideLoading()

}, 500)

}

}

})

}

wx.login({

success: function (msg) {

console.log('code',msg)

if(msg.code){

that.globalData.code = msg.code

if(that.globalData.login==false){

wx.openSetting({

success: function (data) {

if(data) {

if (data.authSetting["scope.userInfo"] == true) {

//loginStatus = true

wx.getUserInfo({

withCredentials: false,

success: function (res) {

console.log('第二次成功',res)

getOpenid(res)

},

fail: function (res) {

that.globalData.login = false

console.log('二次失败',res)

}

})

}else{

that.globalData.login = false

console.log('二次失败02')

}

}

},

fail: function () {

console.info("设置失败返回数据")

}

})

}else{

wx.getUserInfo({

success: function (res) {

console.log('第一次成功',res)

getOpenid(res)

},fail:function(msg){

that.globalData.login = false

console.log('第一次失败',msg)

}

})

}

}

},

fail:function(res){

console.log(res)

}

})

},

globalData:{

userInfo:null,

encryptedData:null,

iv:null,

openid:null,

code:null

}

})
