1、第一次進入  調用 wx.openBluetoothAdapter  正常 2、用  <navigator class="leave-btn" open-type="exit" target="miniProgram" @tap="alreadyLeave">已離場</navigator> 退出小程序 3、再次打開進入  卡死了， 無法 調用 this.initBluetooth() 裡面的 wx.openBluetoothAdapter  onShow() {     this.getAppAuth()     console.log('start up on show ', moment().format('YYYY-MM-DD HH:mm:ss'))     if (this.init === false) {       // 預防進入兩次，小程序機制bug       this.init = true       const value = wx.getStorageSync('WXOpenId')       console.log('value ', value)       if (value) {         globalStore.wxOpenId = value       }       if (globalStore.wxOpenId === ''){         getToken(this.loginWX(), this.getTokenSuccess, this.getTokenFail);       }       else{         wx.getSystemInfo({           success: res => {             console.log('model:' + res.model)             console.log('pixelRatio:' + res.pixelRatio)             console.log('windowWidth:' + res.windowWidth)             console.log('windowHeight:' + res.windowHeight)             console.log('language:' + res.language)             console.log('version:' + res.version)             console.log('platform:' + res.platform)             globalStore.phoneSystem = res.platform             globalStore.phoneSystemVersion = res.version             if(globalStore.phoneSystem === 'devtools'){               globalStore.devParkType === '1' ? this.isMarkLocation() : wx.redirectTo({ url: 'confirm-info' })             }             else{               this.initBluetooth()             }           },           fail: res => {             // curThis.bleError = res.errCode + ' ' + res.errMsg;           }         })       }     }   }
