Javascript 如何限制谷歌地图地理编码API请求URL中的组件

我正在使用谷歌地图地理编码API获取给定城镇/城市的纬度和经度。我试图将JSON响应限制在法国境内的城市/城镇。我已经查阅了我在

但是，即使输入的位置不是城市，请求也会返回坐标。以下是我构建的JSON请求URL

https://maps.googleapis.com/maps/api/geocode/json?address=abc&components=postal_town:abc|country:FR&key=API_KEY

当我使用上述请求时，它会返回以下JSON，尽管“abc”不是有效的town

如何纠正此问题？

地理编码API总是尽最大努力返回结果。这意味着你可能会得到质量不太好的结果。您必须确定如何筛选返回的内容，以确定它是否符合您的需要。@PaulThomasGC这是否意味着尝试使用组件限制构建请求URL不是处理此问题的有效方法？正确。您需要进行查询，然后对结果执行操作，以确定返回的内容是否适合您的需要。例如，如果必须在特定范围内，检查lat/lng是否在这些范围内。
