我在 Google Developer Console 中添加了 Google Maps Geocoding API、Google Places API Web Service 和 Google Maps Javascript API，并收到了一个 API 密钥。

以下是如何将Vuetify Autocompletes 组件与 Google Places API 集成的说明：

1) 添加对 Google Places API 的引用

<script src="https://maps.googleapis.com/maps/api/js?&libraries=places&key=--KEY--"></script>

2) 下面的例子展示了如何使用 AutocompleteService class 的 getPlacePredictions 方法将位置填充到 v-autocomplete 组件中

search(val) {
  if (!val) {
      return;
  }

  this.isLoading = true;

  const service = new google.maps.places.AutocompleteService();
  service.getQueryPredictions({ input: val }, (predictions, status) => {
    if (status != google.maps.places.PlacesServiceStatus.OK) {
      return;
    }

    this.items = predictions.map(prediction => {
      return {
        id: prediction.id,
        name: prediction.description,
      };
    });

    this.isLoading = false;
  });
}
