Android无法使用google api检索附近的地方

Question

我正在尝试使用谷歌地图的 api 获取我发送位置的附近地点。下面是 url(https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=1500&type=restaurant&keyword=cruise&key=YOUR_API_KEY).I 使用 DTO Generator 插件创建了一个 POJO 类。但是在改造的响应方法中，POJO 类中的状态变量给了我 'REQUEST_DENIED'。(Main Activity.java)

Log.e("Res",response.body().getStatus());

我是否以正确的方式使用改造？

RetrofitClient.java：

public class RetrofitClient {
    public static Retrofit retrofit=null;
     static final String baseurl="https://maps.googleapis.com/maps/api/place/nearbysearch/";
    public static Retrofit getClient()
    {
        if (retrofit==null)
        {
            retrofit=new Retrofit.Builder().baseUrl(baseurl).addConverterFactory(GsonConverterFactory.create()).build();
        }
        return retrofit;
    }
}

NearbyApi.java:

public interface NearbyApi {
    @GET("json?")
    Call<NearbyPlaces> getDetails(@Query("location") String loc,
                                  @Query("radius") String radius,
                                  @Query("type") String type,
                                  @Query("keyword") String keyword,@Query("key") String key);

}

MainActivity.java：

String loc="-33.8670522,151.1957362";
    String radius="1500";
    String type="restaurant";
    String keyword="cruise";
    String key="****";
    NearbyApi nearbyApi=RetrofitClient.getClient().create(NearbyApi.class);
                        Call<NearbyPlaces> call=nearbyApi.getDetails(loc,radius,type,keyword,key);
                        call.enqueue(new Callback<NearbyPlaces>() {
                            @Override
                            public void onResponse(Call<NearbyPlaces> call, Response<NearbyPlaces> response) {

    //                                Log.e("Res",response.body().getStatus());
                                Log.e("Res",response.body().getStatus());
                                }

                            @Override
                            public void onFailure(Call<NearbyPlaces> call, Throwable t) {
                                Log.e("Response","Failure");
                            }

Answer 1

前提是您实际上已经拥有 API 密钥，如果没有，

https://developers.google.com/places/web-service/get-api-key

获得 api 密钥并想要启用 api 和服务后，您可以随时前往 api 控制台并启用 api 和服务，

转到https://console.cloud.google.com/apis/dashboard?YOUR_PROJECT

单击启用 API 按钮

启用您要使用的 API 和服务。

您应该启用 Maps SDK for Android 以及您可能想要使用的任何其他服务。

更新：

如果您正在发出 Http 请求（例如@GET），请确保您没有在 api 控制台中对您的 API 施加限制。所以你需要去你生成的密钥，找到以下内容并设置为无限制，

如果您只选择 Android 会发生什么？ 您将能够使用所选 SDK 中的任何对象和方法（例如地点/地图）。

例如，地点 API 中的 PlacePicker 对象。

我正在参考开发者网站上的 places sdk，

https://developers.google.com/places/android-sdk/intro

但是，如果您想发出 HTTP 请求，那么它将被拒绝，因为您的密钥中有限制。
