NativeScript Google-Places API --> 怎么用?

NativeScript Google-Places API --> how to use?

我正在开发使用 Google-Maps-API 的应用,我想添加 search-box 使用 Google-Places-API 自动完成用户目前输入的内容 然后保存选中的项目值。

所以我得到了我的 Google-Places-API 密钥,但我真的不知道把它放在哪里以及如何实现它API.

Google-Maps-API放在androidMAnifest.xml及其工作正常。

<meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="@string/nativescript_google_maps_api_key"
            />

现在我实际上在哪里实现 Google-Places-API 以及我需要在哪里放置密钥?

谢谢!

Places and Maps-utils 插件已经可用。你可以使用它们。你试过了吗?

好的,这就是我所做的并且有效:

我构建了一个 PlacesService,这是代码:

autoCompleteUrl = 'https://maps.googleapis.com/maps/api/place/autocomplete/xml?input=';
autoCompleteUrl2 = '&key=API_KEY'


urlReq='https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=';
urlreq2 = '&inputtype=textquery&fields=formatted_address,name,geometry&key=API_KEY' 


newPlace: any;
constructor(private http :HttpClient){}

auto(typed):any{
    if (typed){
        console.log("got to func",typed)
        return this.http.get(this.autoCompleteUrl+typed+this.autoCompleteUrl2);
    } 
}


findPlace(place):any {
        // return this.http.get(this.urlReq+place+this.urlreq2);
        this.http.get(this.urlReq+place+this.urlreq2)
        .toPromise().then(res => {
            this.newPlace = JSON.stringify(res);
            console.log("#########", this.newPlace); 
        });

}

现在我得到一个看起来像这样的 JSON 对象:

[{"candidates":[{"formatted_address":"United States","geometry":{"location":{"lat":37.09024,"lng":-95.712891},"viewport":{"northeast":{"lat":49.38,"lng":-66.94},"southwest":{"lat":25.82,"lng":-124.39}}},"name":"United States"}],"debug_log":{"line":[]},"status":"OK"}, {"candidates":[{"formatted_address":"United States","geometry":{"location":{"lat":37.09024,"lng":-95.712891},"viewport":{"northeast":{"lat":49.38,"lng":-66.94},"southwest":{"lat":25.82,"lng":-124.39}}},"name":"United States"}],"debug_log":{"line":[]},"status":"OK"}]

但是我该如何拆分这个对象呢?我只想拿 Namegeometry 属性.

谢谢!
