使用 componentRestrictions 时的特定地理编码错误

Question

当我尝试在地理编码时使用 componentRestrictions 时：

geocoder.geocode({
  address: address,
  componentRestrictions: {
    country: 'AU',
  },
}

为了：

address = 'Sydney 2000'（区分大小写）我得到：

{
   "results" : [],
   "status" : "ZERO_RESULTS"
}

然而，`address = 'sydney 2000'` 给我悉尼的正常结果对象

（也适用于格式为 'Melbourne 3000' 的基本上所有其他澳大利亚首府城市）

而如果我使用地区：

geocoder.geocode({
  address: address,
  region: 'AU'
}

再次使用 `address = 'Sydney 2000'`（区分大小写）给我悉尼的正常结果对象

除了 Sydney 2000 之外，我还没有看到任何失败。因此，虽然我可以选择解决这个问题，但我也很困惑为什么它不起作用。

您遇到的问题似乎是 Google 问题跟踪器

中报告的已知问题

4-digit postal codes are hard to geocode (AT, AU, BE, CH, DK, NZ, SI)

据 Google

的工程师说

We are investigating a systemic issue that appears to make postal codes with 4 digits particularly difficult to find in the Geocoding API.

For best result, the recommended request format is to use Component Filtering and Region Biasing towards the desired country:

https://maps.googleapis.com/maps/api/geocode/json?skip_auth&components=postal_code:2725|country:AU&region=AU

In Australia in particular, if feasible in your implementation, adding the administrative_area: filter helps with most postal codes in the 2000-2020 range. (taking into account that postal codes 2001-2005 and 2012-2014 are not in Google Maps at all)

https://maps.googleapis.com/maps/api/geocode/json?&components=country:AU|administrative_area:NSW|postal_code:2006

In other countries, wherever possible adding the locality filter would also help, as noted in #10.

We will keep you posted here.
