基本上我正在为我的网站制作申请表。我需要使用用户输入邮政编码搜索完整地址，并希望提供该邮政编码的结果供他们选择。我知道将需要一个类型的数据库，但我很难找到这个，并希望得到任何帮助。
答案 0 :(得分：2)
在英国，您可以使用192.com从任何邮政编码中获取完整地址。
他们在192.com上有一个完全免费的数据库
我不为他们或他们的任何广告客户工作，但已将此网站用于许多数据录入应用程序。
根据您要搜索的邮政编码格式化网址。即
'a1 1aa'将为http://www.192.com/places/a/a1-1/a1-1aa
然后会列出邮政编码中的所有地址。
这是我写的课程，希望它有所帮助：

我在找到这个答案时发现了这个（通过http://ben-major.co.uk/2012/02/using-google-maps-to-lookup-uk-postcodes/）。希望它有所帮助：
/*fill out the postcode and hit search*/
(function($) {
$.fn.searchPc = function(options) {
var settings = $.extend({
address1: 'address1',
address2: 'address2',
address3: 'address3',
address4: 'address4'
}, options);
return this.each(function() {
var $el = $(this);
var $form = $el.closest('form');
//insert the button on the form
$('<a class="postCodeLookup">Search</a>').insertAfter($el);
$('.postCodeLookup', $form).button({icons:{primary:'ui-icon-search'}});
$form.on('click', '.postCodeLookup', function() {
$.post('http://maps.googleapis.com/maps/api/geocode/json?address='+$el.val()+'&sensor=false', function(r) {
var lat = r['results'][0]['geometry']['location']['lat'];
var lng = r['results'][0]['geometry']['location']['lng'];
$.post('http://maps.googleapis.com/maps/api/geocode/json?latlng='+lat+','+lng+'&sensor=false', function(address) {
$('input[name='+settings.address1+']').val(address['results'][0]['address_components'][0]['long_name']);
$('input[name='+settings.address2+']').val(address['results'][0]['address_components'][1]['long_name']);
$('input[name='+settings.address3+']').val(address['results'][0]['address_components'][2]['long_name']);
$('input[name='+settings.address4+']').val(address['results'][0]['address_components'][3]['long_name']);
});
});
});
});
};
})(jQuery);
$('input[name=postcode]').searchPc({
address2: 'custom_field',
});

我看到你在英国，不幸的是，这意味着可以获得一笔淫秽的金钱来访问皇家邮政Postcode Address File（PAF）。
答案 3 :(得分：0)
您可以使用Googles geolocation api等网络服务。
答案 4 :(得分：0)
您的意思是以下服务吗？
http://www.postcodeanywhere.co.uk/demos/address-finder.aspx
我只是建议这一点，因为我们在工作中使用它并没有给我们带来任何问题，但我认为还有很多其他同样好的选择。
这是一项付费服务（我相信）。

在NL中，您可以通过其邮政编码和房屋编号唯一地标识地址。
并非所有国家/地区都有此属性，因此您的里程可能会有所不同。
但是你会做这样的事情：
SELECT
CONCAT(street,' ','$housenumber') AS streetplusnumber
, city
FROM postcodetostreet p
WHERE p.postcode = '$postcode' and '$housenumber' between minnumber and maxnumber
街道的表格邮编如下：
postcodetostreet
------------------
postcode varchar(6) primary key
street varchar(512)
city
minnumber
maxnumber
数据库通常从第三方购买。
答案 6 :(得分：0)
如果您想在地址表单中添加邮政编码查找解决方案，您需要购买付费服务才能访问皇家邮政的邮政编码地址文件。
Ideal Postcodes 为英国提供了这样的解决方案。您可以在此处查看演示：https://ideal-postcodes.co.uk/postcode-lookup-demo
