小程序登录/授权/个人信息/敏感信息/缓存/音效

1.登录授权

在需要查询是否登录的地方，我这里是在首页的onready中

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

onReady: function () {   //是否授权   wx.getSetting({     success: res => {       if (res.authSetting['scope.userInfo']) {         //已经授权，可以直接调用 getUserInfo 获取头像昵称，不会弹框         console.log("已经授权");         wx.getUserInfo({           success: function (res){             app.globalData.userInfo = res.userInfo           }         })       } else {         console.log("未授权跳转login");         wx.navigateTo({           url: '/pages/login/login',         })       }     }   }) },

 //我这里没有将个人信息存入缓存中，也可以存入缓存然后通过缓存中是否有用户信息来判断是否授权

Login界面中有一个登录按钮

?

1	<button  class='login-btn' open-type='getUserInfo' lang='zh_CN' bindgetuserinfo='onGotUserInfo' hover-class='btn-hover' >微信登录</button>

点击方法：

onGotUserInfo: function (e) {   console.log('errMsg:'+e.detail.errMsg)   console.log(+e.detail.userInfo)   console.log('rawData:'+e.detail.rawData)   if(e.detail.userInfo){     console.log('点击了授权')     app.globalData.userInfo = e.detail.userInfo     wx.login({       success: function(res){         console.log(res)         //返回临时凭证code 传入后台获取openid和session_key         wx.request({           url: 'testurl',           data:{             code:res.code           },           method:'POST',           header:{             'content-type': 'application/json' // 默认值           },           success: function(res){             console.log(res)           }           })       }     })   }else{     console.log('拒绝了授权')   }   wx.navigateBack({         }) },

 2.音效的使用

直接用innerAudioContext播放URL会有延迟，体验很差，可以将资源存入缓存中，通过PATH来播放

globaldata中：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

home_btn:'', next_question:'', wrong_1:'', wrong_2: '', right_1:'', right_2:'', unit_pass_1:'', unit_pass_2:'', unit_pass_3:'', unit_fail:'', game_pass_1:'', game_pass_2:'', game_pass_3:'', game_fail:'',

 

onLaunch中：

?

1 2	self.saveAudioFile('home_btn') self.saveAudioFile('next_question')

saveAuidoFile方法：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

saveAudioFile:function(fileName){     var self = this;     //先判断缓存中是否存在     wx.getStorage({       key: fileName,       success: function(res) {         //存在的话直接赋值给globaldata         self.globalData[fileName] = res.data       },       fail: function(res){         //不存在，将提示音存入本地缓存         wx.downloadFile({           url: self.globalData.audioHeader + fileName + '.mp3',           success(res) {             wx.saveFile({               tempFilePath: res.tempFilePath,               success(res) {                 wx.setStorage({                   key: fileName,                   data: res.savedFilePath,                 })                 //赋值给globaldata                 self.globalData[fileName] = res.savedFilePath               },               fail(res) {                 console.log(res)               }             })           }         })       }     })   },

 播放：

?

1 2 3 4

pointAudioPlay: function (name){   innerAudioContext.src = app.globalData.home_btn   innerAudioContext.play() },

 很方便效果也很好！
