微信小程序授權頁面，效果圖如下

app.js 中的 onLaunch或onShow中加如下代碼，如果沒授權跳轉到授權頁面

    // 獲取用戶信息
    wx.getSetting({
      success: res => {
        if (res.authSetting[‘scope.userInfo‘]) {
          // 已經授權，可以直接調用 getUserInfo 獲取頭像昵稱，不會彈框
          wx.getUserInfo({
            success: res => {
              // 可以將 res 發送給後臺解碼出 unionId
 

              this.globalData.userInfo = res.userInfo

              // 由於 getUserInfo 是網絡請求，可能會在 Page.onLoad 之後才返回
              // 所以此處加入 callback 以防止這種情況
              if (this.userInfoReadyCallback) {
                this.userInfoReadyCallback(res)
              }
            }
          })
        }
 
else{
          // 未授權，跳轉到授權頁面
          wx.reLaunch({
            url: ‘/pages/auth/auth‘,
          })
        }
      }
    })
