我试图通过反向地理编码来获取邮政编码，但要针对某些地址，例如： 陕西西安 中国广西桂林 我无法提取邮政编码。有什么方法可以确保Google Api通过反向地理编码返回给定地址的邮政编码。
请检查以下我用来从lat-lng中获取“城市，州，国家/地区”和邮政编码的邮政编码。
获取邮政编码的入口点- searchPostalCode
const Geocoder = geocoder => {
const extendedGeocoder = {
searchLatLang: address => {
const google = window.google
return new Promise((resolve, reject) => {
geocoder.geocode({
address
}, (addressResults, addressStatus) => {
if (addressStatus === google.maps.GeocoderStatus.OK) {
const addressResult = addressResults[0]
if (addressResult) {
const {
location: {
lat, lng
}
} = addressResult.geometry
resolve({
lat: lat(),
lng: lng()
})
} else {
reject()
}
} else {
reject()
}
})
})
},
extractPostalCode: results => {
return results.reduce((currentPostalCode, address) => {
const newPostalCode = address.address_components.reduce(
(postalCodeValue, component) => {
return component.types[0] === 'postal_code' && !postalCodeValue ? component.long_name : postalCodeValue
},
null
)
return newPostalCode && !currentPostalCode ? newPostalCode : currentPostalCode
}, null)
},
searchPostalCode: address => {
const google = window.google
return new Promise((resolve, reject) => {
return extendedGeocoder
.searchLatLang(address)
.then(location => {
geocoder.geocode({
location
}, (latLngResults, latLngStatus) => {
if (latLngStatus === google.maps.GeocoderStatus.OK) {
resolve(extendedGeocoder.extractPostalCode(latLngResults))
} else {
reject()
}
})
})
.catch(reject)
})
}
}
return extendedGeocoder
}
