Applet login / authorization / personal information / sensitive information / cache / Audio

1. Registration Authority

Where needed query is logged, and I was here in the home of onready

  the onReady: function () { 
    // if the authorization 
    wx.getSetting ({ 
      Success: RES => { 
        IF (res.authSetting [ 'scope.userInfo']) { 
          // has authorized, can directly call getUserInfo nickname acquisition head, not playing block 
          console.log ( "has authorized"); 
          wx.getUserInfo ({ 
            Success: function (RES) { 
              app.globalData.userInfo res.userInfo = 
            } 
          }) 
        } the else { 
          console.log ( "Jump unauthorized login" ); 
          wx.navigateTo ({ 
            URL: '/ Pages / Login / Login', 
          }) 
        } 
      } 
    }) 
  },

 // I do not have personal information stored in the cache, the cache can be stored and then be judged by whether a user is authorized to cache information

Login interface has a login button

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

Click method:

  onGotUserInfo: function (E) { 
    the console.log ( 'errMsg An:' + e.detail.errMsg) 
    the console.log (+ e.detail.userInfo) 
    the console.log ( 'the rawData:' + e.detail.rawData) 
    IF ( e.detail.userInfo) { 
      the console.log ( 'clicked authorization') 
      app.globalData.userInfo = e.detail.userInfo 
      wx.login ({ 
        Success: function (RES) { 
          the console.log (RES) 
          // temporary return certificate acquisition code passed back and openid session_key of 
          wx.request ({ 
            URL: 'testurl', 
            Data: { 
              code: res.code 
            }, 
            Method: 'the POST', 
            header: {  
              'Content-type': 'application / json '// Default
            }, 
            Success:function(res){
              the console.log (RES) 
            } 

          }) 
        } 
      }) 
    } {the else 
      the console.log ( 'rejected authorization') 
    } 
    wx.navigateBack ({ 
      
    }) 
  },

 2. The use of sound

URL directly innerAudioContext play will be delayed, experience is poor, resources can be stored in the cache, to play by PATH

globaldata in:

    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 in:

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

saveAuidoFile method:

saveAudioFile: function (fileName) { 
    var = Self the this; 
    // first determine whether there is a cache 
    wx.getStorage ({ 
      Key: fileName, 
      Success: function (RES) { 
        // exists directly assigned to GlobalData 
        self.globalData [fileName] res.data = 
      }, 
      Fail: function (RES) { 
        // do not exist, the tone into the local cache 
        wx.downloadFile ({ 
          URL: self.globalData.audioHeader + + fileName '.mp3', 
          Success (RES) { 
            wx.saveFile ({ 
              the 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)
              }
            })
          }
        })
      }
    })
  },

 Play:

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

 Very convenient also very effective!
