微信小程序的开启受权，当单机取消受权后 再次受权

 //单机去搜索
  toSearch:function(){
    this.getLocation(res => {
      console.log('成功')
      wx.navigateTo({
        url: `../search_new/search_new`,
      })
    }, res => {
      console.log('失败')
      wx.showModal({
        title: '获取定位失败',
        content: '亲~，没有定位无法进行搜索哟~,去打开地理位置吧~',
        confirmText: '确认',
        cancelText: "取消",
        success: (ress) => {
          //确认，去打开位置受权
          if (ress.confirm) {
            wx.openSetting({
              success: (ress) => {
                console.log(ress)
                if (ress.authSetting['scope.userLocation']) {
                  wx.navigateTo({
                    url: `../search_new/search_new`,
                  })
                }
              },
            })
            //取消二次受权，显示最新上架
          } else if (ress.cancel) {

          }
        }
      })
    })
  },

//位置受权
  getLocation: function (successCallBack, errorCallBack){
    wx.getLocation({
      type: 'wgs84',
      success(res) {
        successCallBack(res)
      },
      fail(res){
        errorCallBack(res)
      }
    })
  },
