我正在尝试构建一个类似的地图，您可以在拖动地图时查看地点标记。我想在地图上显示来自 Google Places API 的“酒店”标记。
使用以下 JavaScript 代码谷歌地图 https://developers.google.com/maps/documentation/javascript/examples/place-search，我可以在 Google 地图上显示酒店，但我想用 React 来做到这一点，使用反应谷歌地图 https://github.com/tomchentw/react-google-maps.

反应谷歌地图 https://tomchentw.github.io/react-google-maps/#searchbox有一个显示搜索输入字段的示例。这样我就可以通过搜索来搜索并显示标记，例如“伦敦的酒店”。但我不想搜索地点，而是想立即显示酒店的标记。 （下例中的API密钥来自react-google-maps示例。）
const _ = require("lodash");
const { compose, withProps, lifecycle } = require("recompose");
const {
withScriptjs,
withGoogleMap,
GoogleMap,
Marker,
} = require("react-google-maps");
const { SearchBox } = require("react-google-maps/lib/components/places/SearchBox");
const MapWithASearchBox = compose(
withProps({
googleMapURL: "https://maps.googleapis.com/maps/api/js?key=AIzaSyC4R6AN7SmujjPUIGKdyao2Kqitzr1kiRg&v=3.exp&libraries=geometry,drawing,places",
loadingElement: <div style={{ height: `100%` }} />,
containerElement: <div style={{ height: `400px` }} />,
mapElement: <div style={{ height: `100%` }} />,
}),
lifecycle({
componentWillMount() {
const refs = {}
this.setState({
bounds: null,
center: {
lat: 41.9, lng: -87.624
},
markers: [],
onMapMounted: ref => {
refs.map = ref;
},
onBoundsChanged: () => {
this.setState({
bounds: refs.map.getBounds(),
center: refs.map.getCenter(),
})
},
onSearchBoxMounted: ref => {
refs.searchBox = ref;
},
onPlacesChanged: () => {
const places = refs.searchBox.getPlaces();
const bounds = new google.maps.LatLngBounds();
places.forEach(place => {
if (place.geometry.viewport) {
bounds.union(place.geometry.viewport)
} else {
bounds.extend(place.geometry.location)
}
});
const nextMarkers = places.map(place => ({
position: place.geometry.location,
}));
const nextCenter = _.get(nextMarkers, '0.position', this.state.center);
this.setState({
center: nextCenter,
markers: nextMarkers,
});
// refs.map.fitBounds(bounds);
},
})
},
}),
withScriptjs,
withGoogleMap
)(props =>
<GoogleMap

</SearchBox>
{props.markers.map((marker, index) =>
<Marker key={index} position={marker.position} />
)}
</GoogleMap>
);
<MapWithASearchBox />
我已经尝试解决这个问题很多天了，并且一直在寻找教程，但我找不到解决方案。我明白我应该使用：
new google.maps.places.PlacesService()
并添加选项：
const center = new google.maps.LatLng(37.422, -122.084068);
const options = {
location: center
radius: '500',
types: ['hotel']
};
当使用react-google-maps时，我需要使用与Scriptjs。但我如何将所有这些整合在一起呢？
我如何使用react-google-maps谷歌地方信息API https://developers.google.com/maps/documentation/javascript/examples/place-search，在地图上显示 Google 的“酒店”标记？
