浅谈小程序如何授权登录,获取信息和手机号
本篇文章给大家分享一下微信小程序实现授权登录,并获取用户信息和手机号的方法。

总结,新增获取用户手机号功能,里面用到了关于获取用户信息和用户手机号的功能,一开始写的时候发现我把两个按钮写在一个登录页面上,获取手机号逻辑是当用户点击授权之后跳转到首页,当点击拒绝弹窗提示,最后发现可能是微信上的限制,模拟器调试拒绝有提示,真机点击拒绝也是能跳的,没办法又写了一套关于用户进入某个详情页判断手机号授权问题,这里记录一下,希望能帮到有需要的朋友,先看下效果!!!
1.全局判断
App({ onLaunch: function () { //调用API从本地缓存中获取数据 // 展示本地存储能力 var logs = wx.getStorageSync('logs') || [] logs.unshift(Date.now()) wx.setStorageSync('logs', logs) var that = this; //获取用户本地是否是第一次进入新版本 var versions = wx.getStorageSync('versions'); console.log('versions:' + versions); //判断是不是需要授权 if (versions == '1'){ // 已经授权,可以直接调用 getUserInfo 获取头像昵称,不会弹框 wx.getUserInfo({ success: function (res) { that.globalData.userInfo = res.userInfo console.log(that.globalData.userInfo) }, fail: function () { wx.redirectTo({ url: '../wurui_house/pages/login/index', }) } }) }else{ //未授权, 跳转登录页面 wx.redirectTo({ url: '../wurui_house/pages/login/index', }) } }, onShow: function () { // console.log(getCurrentPages()) }, onHide: function () { // console.log(getCurrentPages()) }, onError: function (msg) { //console.log(msg) }, util: require('we7/resource/js/util.js'), tabBar: { "color": "#123", "selectedColor": "#1ba9ba", "borderStyle": "#1ba9ba", "backgroundColor": "#fff", "list": [ ] }, getLocationInfo: function (cb) { var that = this; if (this.globalData.locationInfo) { cb(this.globalData.locationInfo) } else { wx.getLocation({ type: 'gcj02', // 默认为 wgs84 返回 gps 坐标,gcj02 返回可用于 wx.openLocation 的坐标 success: function (res) { that.globalData.locationInfo = res; cb(that.globalData.locationInfo) }, fail: function () { // fail }, complete: function () { // complete } }) } }, globalData: { userInfo: null, appid: "", appsecret: "", }, siteInfo: require('siteinfo.js') });
2.login登录页判断
(一)index.wxml
<view wx:if="{{isHide}}"> <view wx:if="{{canIUse}}"> <view> <image src='../../../we7/resource/images/login.png'></image> </view> <view> <text>请依次允许获得你的公开信息及手机号码</text> </view> <view class="" > <button class="{{flag?'show':'hide'}}" type="primary" open-type="getUserInfo" bindgetuserinfo="bindGetUserInfo">{{AuthorizedLogin}}</button> <button class="{{flag?'hide':'show'}}" type="primary" open-type='getPhoneNumber' bindgetphonenumber="getPhoneNumber">{{UserPhone}}</button> </view> </view> <view wx:else>请升级微信版本</view> </view>
(四)index.wxss
.header { margin: 90rpx 0 90rpx 50rpx; border-bottom: 1px solid #ccc; text-align: center; width: 650rpx; height: 300rpx; line-height: 450rpx; } .header image { width: 200rpx; height: 200rpx; } .content { margin-left: 50rpx; margin-bottom: 90rpx; } .content text { display: block; color: #9d9d9d; margin-top: 40rpx; } /* .operBtn{ border-radius: 80rpx; margin: 70rpx 50rpx; font-size: 35rpx; } .operBtns{ background: #eef0ed !important; border-radius: 80rpx; margin: 70rpx 50rpx; font-size: 35rpx; color: #000300 !important; } */ .hide{ border-radius: 80rpx; margin: 70rpx 50rpx; font-size: 35rpx; display: none; } .show{ display: block; /* background: #eef0ed !important; */ border-radius: 80rpx; margin: 70rpx 50rpx; font-size: 35rpx; /* color: #000300 !important; */ }
(三)index.js
const app = getApp(); Page({ data: { //判断小程序的API,回调,参数,组件等是否在当前版本可用。 canIUse: wx.canIUse('button.open-type.getUserInfo'), isHide: false, AuthorizedLogin: '授权登录', UserPhone: '手机号授权', lee: "", flag: true }, onLoad: function() { var that = this; // 查看是否授权 //获取用户本地是否是第一次进入新版本 var versions = wx.getStorageSync('versions'); if (versions == '1') { wx.getSetting({ success: function(res) { if (res.authSetting['scope.userInfo']) { //调用共通的登录方法 app.util.getUserInfo( function(userinfo) { that.setData({ userinfo: userinfo }) }); } else { // 用户没有授权 // 改变 isHide 的值,显示授权页面 that.setData({ isHide: true }); } } }); } else { // 用户没有授权 // 改变 isHide 的值,显示授权页面 that.setData({ isHide: true }); } }, bindGetUserInfo: function(e) { if (e.detail.userInfo) { //用户按了允许授权按钮 var that = this; let user = e.detail.userInfo; // 获取到用户的信息了,打印到控制台上看下 console.log("用户的信息如下:"); console.log(user); //授权成功后,通过改变 isHide 的值,让实现页面显示出来,把授权页面隐藏起来 that.data.lee if (that.data.lee == '') { wx.showToast({ icon: "none", title: '请继续点击获取手机号', }), that.setData({ isHide: true, flag: (!that.data.flag), lee: true }) that.wxlogin(); } else if (!that.data.lee) { wx.switchTab({ url: "/wurui_house/pages/index/index" }) } } else { //用户按了拒绝按钮 wx.showModal({ title: '警告', content: '您点击了拒绝授权,将无法进入小程序,请授权之后再进入!!!', showCancel: false, confirmText: '返回授权', success: function(res) { // 用户没有授权成功,不需要改变 isHide 的值 if (res.confirm) { console.log('用户点击了“返回授权”'); } } }); } }, wxlogin: function() { //获取用户的openID var that = this; //调用共通的登录方法 app.util.getUserInfo( function(userinfo) { that.setData({ userinfo: userinfo }) }); }, getPhoneNumber: function(e) { //点击获取手机号码按钮 var that = this; that.data.lee if (that.data.lee == '') { wx.showToast({ icon: "none", title: '请先点击获取用户信息', }) return } else { wx.checkSession({ success: function(res) { console.log(e.detail.errMsg) console.log(e.detail.iv) console.log(e.detail.encryptedData) var ency = e.detail.encryptedData; var iv = e.detail.iv; var sessionk = that.data.sessionKey; if (e.detail.errMsg == 'getPhoneNumber:fail user deny') { wx.showModal({ title: '警告', content: '您点击了拒绝授权,部分功能无法使用!!!', showCancel: false, confirmText: '返回授权', success: function(res) { // 用户没有授权成功,不需要改变 isHide 的值 if (res.confirm) { wx.setStorageSync('enws', '1'); wx.switchTab({ url: "/wurui_house/pages/index/index" }) console.log('用户点击了“返回授权”'); }; } }), that.setData({ modalstatus: true, }); } else { that.setData({ lee: false, }); wx.switchTab({ url: "/wurui_house/pages/index/index" }) //同意授权 var userinfo = wx.getStorageSync('userInfo'); app.util.request({ 'url': 'entry/wxapp/saveusermobile', data: { sessionid: userinfo.sessionid, uid: userinfo.memberInfo.uid, iv: iv, encryptedData: ency }, success: function(res) { if (res.data.data.error == 0) { console.log('success' + res.data.data); //用户已经进入新的版本,可以更新本地数据 wx.setStorageSync('versions', '1'); wx.setStorageSync('enws', '2'); } else { //用户保存手机号失败,下次进入继续授权手机号 wx.setStorageSync('enws', '1'); console.log('fail' + res.data.data); } }, fail: function(res) { console.log('fail' + res); } }); } }, fail: function() { console.log("session_key 已经失效,需要重新执行登录流程"); that.wxlogin(); //重新登录 } }); } } })
2.某个详情页手机号授权判断
使用的遮罩层写法
(一)index.html
<code> <!-- 受权弹框提醒 --> <view class="container"> <view class="float" hidden='{{viewShowed}}'> <view class='floatContent'> <text>允许授权获取手机号</text> <view class='floatText'> <button bindtap='cancle' class='btn-cancle'>取消</button> <button class='btn-cancle' open-type='getPhoneNumber' bindgetphonenumber="getPhoneNumber">确认</button> </view> </view> </view> </view> </code>
(二)index.wxss
/* 手机号授权 */ .float { height: 100%; width: 100%; position: fixed; background-color: rgba(0, 0, 0, 0.5); z-index: 2; top: 0; left: 0; } .floatContent { /* padding: 20rpx 0; */ width: 80%; background: #fff; margin: 40% auto; border-radius: 20rpx; display: flex; flex-direction: column; justify-content: space-around; align-items: center; position: relative; height: 255rpx; } .floatContent text { color: #000; font-size: 40rpx; display: block; margin: 0 auto; position: absolute; top: 50rpx; /* text-align: center; */ /* line-height: 60rpx; */ border-radius: 30rpx; } .floatText{ width: 100%; height: 100rpx; display: flex; justify-content: flex-start; position: absolute; bottom: 0; } .btn-cancle{ line-height: 100rpx; flex: 1; margin: 0; padding: 0; border-radius: none; }
(三)index.js
data: { viewShowed: true, //控制授权能否显示 }, cancle: function () { wx.setStorageSync('enws', '2'); this.setData({ viewShowed: true }) }, /** * 生命周期函数--监听页面显示 */ onShow: function () { var enws = wx.getStorageSync('enws'); console.log("enws:", +enws); var that = this; if (enws != '2') { //判断能否授权 that.setData({ viewShowed: false, }) console.log('判断能否授权'); } else { } }, getPhoneNumber: function (e) { //点击获取手机号码按钮 var that = this; wx.checkSession({ success: function (res) { console.log(e.detail.errMsg) console.log(e.detail.iv) console.log(e.detail.encryptedData) var ency = e.detail.encryptedData; var iv = e.detail.iv; var sessionk = that.data.sessionKey; that.setData({ viewShowed: true, }) wx.setStorageSync('enws', '2'); if (e.detail.errMsg == 'getPhoneNumber:fail user deny') { } else { //同意授权 var userinfo = wx.getStorageSync('userInfo'); app.util.request({ 'url': 'entry/wxapp/saveusermobile', data: { sessionid: userinfo.sessionid, uid: userinfo.memberInfo.uid, iv: iv, encryptedData: ency }, success: function (res) { console.log('success' + res); if (res.data.data.error == 0) { console.log('success' + res.data.data); //用户已经进入新的版本,可以更新本地数据 wx.setStorageSync('versions', '1'); } else { //用户保存手机号失败,下次进入继续授权手机号 } }, fail: function (res) { console.log('fail' + res); } }); } } }); },
