## H5 API定位 ##

> 总结：定位非常不准，并且成功率很低。

## 高德定位 ##

需要在https域名下调用，本地调用偶尔能成功

/** * 高德精确定位 * @param {*} config * https://lbs.amap.com/api/javascript-api/reference/location#m_AMap.Geolocation */

            timeout: 1000, //超过10秒后停止定位，默认：5s
            buttonPosition: 'RB', //定位按钮的停靠位置

          });

        }
        //解析定位错误信息
        function onError(error) {

          return rej(error);
        }
    
        // res({ 
        // longitude: '120.023763,',

      });
    }
