java - Google map Java 客户端 - GeocodingApi.reverseGeocode 不返回结果

Question

全部。

我正在使用 Google map 服务 Java 客户端 ( https://github.com/googlemaps/google-maps-services-java ) 在我的应用中提供一些简单的地址和距离功能。

我正在使用 Gradle 构建项目，以下是我的依赖项:

dependencies {   
    compile 'com.google.maps:google-maps-services:0.2.7'
    compile 'org.slf4j:slf4j-nop:1.7.25'
}

当我在浏览器中使用 URL 请求时，一切正常: https://maps.googleapis.com/maps/api/geocode/json?latlng=-3.775657,-38.456086&key=APP_KEY

这将返回 json:

   ],
   "status" : "OK"

但是当我尝试对 Java 客户端执行相同的操作时，我没有得到任何结果。我的代码:

public void loadAddress() throws ApiException, InterruptedException, IOException {
        LatLng location = new LatLng(latCoordinate, longCoordinate);

        GeoApiContext context = new GeoApiContext.Builder().apiKey("<APP_KEY>").build();
        GeocodingApiRequest request = GeocodingApi.reverseGeocode(context, location);
        GeocodingResult[] results = request.await();

        int i = 0;
        System.out.println("Results length: " + results.length);
        for (GeocodingResult result : results) {
            System.out.println("Result " + (++i) + ": " +result.formattedAddress);
            System.out.println("Latitude: " + result.geometry.location.lat);
            System.out.println("Longitude: " + result.geometry.location.lng);
        }

    }

控制台:

C:\Workspace\Java\GoogleAPITests>gradlew run
Task :run
Results length: 0

如你所见，request.await();没有返回预期值。有什么建议吗？

Answer 1

这里不是开玩笑，但是你的latCooperative和longCooperative在哪里设置的？它们不是这个公共(public)方法的参数，所以我假设它们是在某个地方设置的。也许可以在位置构造函数调用之前尝试 println。
