改进动态URL问题

Question

我是Retrofit 2的新手,我正在尝试在我的应用中集成Google Place API.我的问题是如何在使用Retrofit 2.0时继续使用这种动态URL.

网址:

  https://maps.googleapis.com/maps/api/place/autocomplete/json?input="{Place Name}"&location="{Lat,long}"&key="{API KEY}"

我的模型类名称是:

1)PlaceAutoComplete

2)PlacePredictions

public class PlaceAutoComplete {

private String place_id;
private String description;

public String getPlaceDesc() {
    return description;
}

public void setPlaceDesc(String placeDesc) {
    description = placeDesc;
}

public String getPlaceID() {
    return place_id;
}

public void setPlaceID(String placeID) {
    place_id = placeID;
}

}

和

public class PlacePredictions {

  public ArrayList<PlaceAutoComplete> getPlaces() {
    return predictions;
}

  public void setPlaces(ArrayList<PlaceAutoComplete> places) {
    this.predictions = places;
}

  private ArrayList<PlaceAutoComplete> predictions;
}

我已经为Retrofit创建了WebServiceCall.java类,这是我的代码

public class WebServiceCall {
private static WebServiceCall webServiceCall;
public RetrofitService retrofitService;
private String currentDateTimeString;

public WebServiceCall() {
    OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
    if (Boolean.parseBoolean("true")) {
        HttpLoggingInterceptor httpLoggingInterceptor = new   HttpLoggingInterceptor();            httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        clientBuilder.connectTimeout(100000, TimeUnit.MILLISECONDS);
        clientBuilder.addInterceptor(httpLoggingInterceptor);
    }



    retrofitService = new Retrofit.Builder()
                .baseUrl("https://maps.googleapis.com/maps/api/place/autocomplete/json")
            .client(clientBuilder.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
            .create(RetrofitService.class);
    currentDateTimeString =      DateFormat.getDateTimeInstance().format(new Date());
}

public static WebServiceCall getInstance() {
    if (webServiceCall == null) {
        webServiceCall = new WebServiceCall();
    }
    return webServiceCall;
}
}  

我在调用URL时使用此接口:但我无法继续前进.

 public interface RetrofitService {

@GET("?input=")
Call<PlaceAutoComplete> getInput(@Url String url);

}

我一直在谷歌和StackOverflow搜索,但没有让我理解.详细解释将非常值得注意.

谢谢.

改造1:

@GET("/place/autocomplete/json")
void getDetails(
             @Query("input") String input,
             @Query("location") String location, 
             @Query("key") String key,
             Callback<Response> callback);

如果参数未知,您应该创建如下参数:

@GET("/place/autocomplete/json")
@FormUrlEncoded
void getDetails(
              @FieldMap Map<String, String> params,
              Callback<Response> callback);

改造2

    @GET("place/autocomplete/json")
    Call<List<Response>> getDetails(
                            @Query("input") String input,
                            @Query("location") String location, 
                            @Query("key") String key);

对于未知的参数:

  @GET("place/autocomplete/json")
  Call<List<Response>> getDetails(
                             @QueryMap Map<String, String> options);

并且您应该使用尾随/在基本URL的末尾进行这样的设置:

retrofitService = new Retrofit.Builder() 
            .baseUrl("https://maps.googleapis.com/maps/api/")
            .client(clientBuilder.build())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
