  var key = config.Config.key; // 前面添加的应用的key
  var myAmapFun = new amapFile.AMapWX({
    key: key
  });
  myAmapFun.getRegeo({
    success: function(data) {
      //获取定位成功
      console.log("定位成功", data)
      //获取位置编码
      var adCode = data[0].regeocodeData.addressComponent.adcode;
      //保存省市编码
      if (adCode && adCode.length >= 4) {
        var areaCode = parseInt(adCode)
        var area = data[0].regeocodeData.addressComponent.district
        var cityCode = adCode.slice(0, 4) + "00"
        var city = data[0].regeocodeData.addressComponent.city
        var provinceCode = adCode.slice(0, 2) + "0000"
        var province = data[0].regeocodeData.addressComponent.province
        that.setData({
