通过 Google 地图 API 反向地理编码 [REQUEST_DENIED]

Question

我的 VALID 和 ENABLED Google API 密钥在我请求反向地理编码时生成来自地图地理编码 API 的 REQUEST_DENIED 响应。相同的 GOOGLE_API_KEY 与 Maps Static API 和 Maps SDK for Android API 在同一个项目中完美运行。是的，我启用了地理编码 API 进行计费。

我不明白为什么它不起作用，请帮助。

我的代码：

static Future<String> getPlaceAddress(double lat, double lng) async {
    final url = Uri.parse(
        'https://maps.googleapis.com/maps/api/geocode/json?latlng=$lat,$lng&amp;key=$GOOGLE_API_KEY');

    final response = await http.get(url);
    
    return json.decode(response.body)['results'][0]['formatted_address'];
  }

控制台上的错误消息：

Answer 1

错误消息表明您没有在请求中使用 API 键。好像是因为请求中的amp;所以最后的key参数被省略了。删除 amp;，您的请求将起作用。
