我开始使用诺基亚地图 API，并且在对地址进行地理编码（获取地址的纬度/经度）时注意到了一些奇怪之处。
我在搜索“ 1348 Louvain-la-Neuve,Belgium,Belgium ”
它在数组中返回了一个带有地址和位置的结果；不幸的是，返回的地址似乎是法语，而不是我的自然语言环境。
返回的地址部分，返回给我一个国家值“比利时”而不是预期的“比利时”。有没有办法强制通过我的英语语言环境，而不是似乎是搜索国家的语言环境。
（我也意识到这可能不是语言环境问题，而是国家的官方名称，这对我来说仍然是一个问题，因为我用英语处理）
这是一个错误（票号：JSLA-3608）。添加更改地理编码请求的区域设置应该是这种情况nokia.Settings.set("defaultLanguage", "en-GB"); ，但在我看来，地理编码函数没有将区域设置传递给地理编码服务。有趣的是，reverseGeocoding 服务确实正确传递了语言环境，因此可以使用一种变通方法来获取首选语言环境：
searchManager.geoCode({
searchTerm: "1348 Louvain-la-Neuve,Belgium,Belgium",
onComplete: function (data, requestStatus, requestId) {
processResults(data, requestStatus, requestId);
map.zoomTo(addressesContainer.getBoundingBox());
}
});
返回“比利时”
然而：
searchManager.geoCode({
searchTerm: "1348 Louvain-la-Neuve,Belgium,Belgium",
onComplete: function (data, requestStatus, requestId) {
nokia.places.search.manager.reverseGeoCode({
latitude: data.location.position.latitude,
longitude: data.location.position.longitude,
onComplete: function (data, status) {
processResults(data, requestStatus, requestId);
map.zoomTo(addressesContainer.getBoundingBox());
}
});
}
});
返回“比利时”。
这是一个完整的示例（使用您自己的应用程序 ID 和令牌）
