使用Google api匹配城市和州
Matching city and state using Google API's?
我需要使用Google API检查给定的城市和州的组合是否正确。
Ways I found so far
1。USING GeoCoding API:
我们可以调用zipCode，它将返回一个JSON。有一个描述格式化地址的字段，其中包含城市、州、邮政编码、地区等。
http://maps.googleapis.com/maps/api/geocode/json?address=ZIPCODE&sensor=true
2。ZIPtastic API
与上面的类似，但它返回的信息较少。
但现在我想做没有ZIPCode。[我。e]城市和国家是给定的，我需要检查给定的组合是否正确使用API。有什么办法吗?请提一些建议。
编辑:我需要检查给定的城市，州，国家，邮政编码是否正确。
http://maps.googleapis.com/maps/api/geocode/json?address=NY&address=10001&sensor=true&components=country:US
上面的返回与
相同的结果http://maps.googleapis.com/maps/api/geocode/json?address=NY&address=10001&sensor=true&address=albanycomponents=country:US
邮编是10001，州是纽约，城市是奥尔巴尼，国家是美国。为什么它返回相同的结果。我得到正确的结果或做什么?
您可以在GeoCoding API的address参数中使用您想要的内容，例如:
http://maps.googleapis.com/maps/api/geocode/json?address=Paris&sensor=true
这里我得到了匹配地址Paris的结果:法国的Paris，德克萨斯州的Paris等。
因此，您可以使用它来输入您的城市并检查状态是否有效。为此，也将搜索限制在美国，使用以下补语:components=country:US
示例:http://maps.googleapis.com/maps/api/geocode/json?address=Paris&sensor=true&components=country:US

然后你解析JSON，并能够找到你想要的，与administrative_area_level_1字段在这里的状态!
locality字段:
http://maps.googleapis.com/maps/api/geocode/json?sensor=true&components=country:US|locality:Paris过滤来自其他字段名称Paris的可能结果
在angular中写了一个函数来获取地址
public formatAddress(googleAddr: any): any {
let properAddress: any = {
latitude: '',
longitude: '',
address: '',
premises: '',
area: '',
street: '',
locality: '',
state: '',
country: '',
timezone: '',
pincode: ''
};
let acutalPremise = '';
if (googleAddr && googleAddr.address_components) {
googleAddr.address_components.forEach((addr:any) => {
// country
if (addr.types.indexOf('country') != -1) {
properAddress.country = addr.long_name;
}
// state
if (addr.types.indexOf('administrative_area_level_1') != -1) {
properAddress.state = addr.long_name;
}
// Area
if (addr.types.indexOf('sublocality_level_1') != -1) {
properAddress.area = addr.long_name;
}
// locality
if (addr.types.indexOf('locality') != -1) {
properAddress.locality = addr.long_name;
}
// street
if (addr.types.indexOf('route') != -1) {
properAddress.street = addr.long_name;
}
// acutal address premises
if (addr.types.indexOf('premise') != -1) {
acutalPremise = addr.long_name;
}
// postal code
if (addr.types.indexOf('postal_code') != -1) {
properAddress.pincode = addr.long_name;
}
});
}
// get the timezone
properAddress.latitude = googleAddr.geometry.location.lat();
properAddress.longitude = googleAddr.geometry.location.lng();
properAddress.address = googleAddr.name + ', ' + googleAddr.formatted_address;
properAddress.premises = properAddress.street || acutalPremise ? googleAddr.name : '';
return properAddress;
}
