主动打开手机定位功能

export function getLocationListener(){
  return new Promise((resolve, reject) => {
    var that = this
    wx.openSetting({
      success(res){
        if (res.authSetting["scope.userLocation"] === true) {
          // wx.showToast({
          //   title: '授权成功',
          //   icon: 'none',
          //   duration: 1000
          // })
          wx.getLocation({
            isHighAccuracy: true,
            success(res) {
              resolve(res)
            },
          });
        } else {
          wx.showToast({
            title: '授权失败',
            icon: 'none',
            duration: 1000
          })
          wx.navigateBack({
            delta: -1
          });
          reject(false)
        }
      },
      fail: function () {
        reject(false)
      }
    })
  })
}

const res = await getLocationListener()
    this.setData({
      flag:true,
      ['queryGoodsInfo.lat']: res.latitude,
      ['queryGoodsInfo.lon']: res.longitude
    })

定位代码根据需求修改使用

export function locationListener(){
  return new Promise((resolve, reject) => {
    wx.getLocation({
      success(res) {
        resolve(res)
      },
      fail() {
        wx.getSetting({
          success(res) {
            var statu = res.authSetting;
            if (!statu['scope.userLocation']) {
              resolve(true)
            }
          },
          fail: function (res) {
            wx.showToast({
              title: '授权失败',
              icon: 'none',
              duration: 1000
            })
            reject(false)
          }
        })
      }
    })
  })
}
