Auf dieser Seite wird beschrieben, wie Sie einen API-Schlüssel erhalten, die erforderlichen APIs aktivieren und die Places Library laden, damit Sie die „Place“-Klasse verwenden können.
API-Schlüssel anfordern und die erforderlichen APIs aktivieren
Vor Verwendung der „Place“-Klasse sind folgende Schritte erforderlich:
- Erstellen Sie ein Cloud-Projekt mit einem Rechnungskonto.
- Fordern Sie einen API-Schlüssel an.
- Aktivieren Sie folgende APIs:
- Maps JavaScript API
- Places API
- Places API (New) – für die Verwendung von „Text Search (New)“ und „Place Autocomplete“ erforderlich
Weitere Informationen finden Sie unter Google Cloud-Projekt einrichten.
API-Schlüssel anfordern
Places API (New) aktivieren
Places Library laden
Um die Places Library zu laden, müssen Sie zuerst die Maps JavaScript API laden. Fügen Sie dazu das Inline-Bootstrap-Ladeprogramm in Ihren Anwendungscode ein, wie im folgenden Snippet gezeigt:
<script>
(g=>{var h,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=>h||(h=new Promise(async(f,n)=>{await (a=m.createElement("script"));e.set("libraries",[...r]+"");for(k in g)e.set(k.replace(/[A-Z]/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})({
key: "YOUR_API_KEY",
v: "weekly",
// Use the 'v' parameter to indicate the version to use (weekly, beta, alpha, etc.).
// Add other bootstrap parameters as needed, using camel case.
});
</script>
Verwenden Sie den Operator await
, um importLibrary()
innerhalb einer async
-Funktion aufzurufen:
const {Place} = await google.maps.importLibrary("places");
Ihre Funktion kann auch Bibliotheken laden, ohne eine Variable für die erforderlichen Klassen zu deklarieren:
async function initMap() {
google.maps.importLibrary("places");
...
}
initMap();
Alternativ können Sie die Bibliotheken direkt in HTML laden, wie hier gezeigt:
<script>
google.maps.importLibrary("places");
</script>
Weitere Informationen zum Laden von Bibliotheken finden Sie unter Maps JavaScript API laden.

Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nThis page shows you how to get an API key, enable the required APIs, and load the Places Library,\nso that you can work with the Place class.\n\nGet an API key and enable the required APIs\n\nBefore using the Place class, you need to:\n\n- Create a Cloud project with a billing account.\n- Get an API key.\n- Enable the following APIs: \n - Maps JavaScript API\n - Places API\n - Places API (New) (required to use Text Search (New) and Place Autocomplete)\n\nTo learn more, see [Set up your Google Cloud project](/maps/documentation/javascript/cloud-setup).\n[Get an API key](/maps/documentation/javascript/get-api-key)\n\n\n[Enable Places API (New)](https://console.cloud.google.com/apis/library/places.googleapis.com)\n\nLoad the Places Library\n\nTo load the Places Library, first load the Maps JavaScript API, by adding the\ninline bootstrap loader to your application code, as shown in the following snippet: \n\n```javascript\n\u003cscript\u003e\n (g=\u003e{var h,a,k,p=\"The Google Maps JavaScript API\",c=\"google\",l=\"importLibrary\",q=\"__ib__\",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=\u003eh||(h=new Promise(async(f,n)=\u003e{await (a=m.createElement(\"script\"));e.set(\"libraries\",[...r]+\"\");for(k in g)e.set(k.replace(/[A-Z]/g,t=\u003e\"_\"+t[0].toLowerCase()),g[k]);e.set(\"callback\",c+\".maps.\"+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=\u003eh=n(Error(p+\" could not load.\"));a.nonce=m.querySelector(\"script[nonce]\")?.nonce||\"\";m.head.append(a)}));d[l]?console.warn(p+\" only loads once.
