我想使用Google Maps API获取邮政编码的坐标。
我正在使用此文档：https://developers.google.com/maps/documentation/geocoding/intro?csw=1
当我现在想要搜索邮政编码1200（瑞士日内瓦）时，我使用此URL：
https://maps.google.com/maps/api/geocode/json?region=ch&components=postal_code:1200
我得到了很多不同的结果，但在瑞士却没有（结果是在问题的最后）。看起来region参数根本不起作用，因为我在其他国家获得了结果。
当我搜索1201（也是日内瓦）时，它有效。
知道为什么吗？我宁愿得不到任何结果然后错误的结果（在其他国家的结果）

答案 0 :(得分：2)
与 duncan 一样，region code只会影响（而非完全限制）地理编码器的结果。要了解更多信息，请查看region biasing。
如果您想在某个国家/地区使用特定结果，请使用 component = country 而不是某个地区。
我尝试在瑞士国家/地区申请 postal_code：1200 。我得到零结果。因此，请确保您使用的请求有效。
https://maps.google.com/maps/api/geocode/json?components=postal_code:1200|country:CH
如果我尝试 postal_code：1201 ，我会得到您想要的具体结果。
https://maps.google.com/maps/api/geocode/json?components=postal_code:1201|country:CH
如果您确定 postal_code：1200 在瑞士是有效的邮政编码，则可能该邮政编码不被Google地图视为瑞士日内瓦的邮政编码。
还要尝试检查我回答的相关SO question。
