Small program WeChat positioning is not accurate

It is related to the WeChat positioning type！类型改为gcj02,加上属性isHighAccuracy为trueprecise positioning10m以内

wx.getLocation({
    
	type: 'gcj02',
	isHighAccuracy: true,//开启高精度定位
       // 获取地理位置成功
       success(res) {
    
         if (callback) callback(res);
       },
       // 获取地理位置失败
       fail() {
    }
     });

getLocation: function(callback, fail) {
    
    let that = this;
    wx.authorize({

      success() {
    
        // 获取地理位置
        that.location(callback);
      },
      // 拒绝-获取地理位置
      fail() {
    
        // 获取用户当前设置
