问题描述

我有一个文本框，用户将在其中输入一个地标，我必须检索该地标的邮政编码.我不知道如何完成这项任务.我需要一些帮助

解决方案

Google 是您的最佳选择.在 Google Map API 上使用反向地理编码(地址查找)来检索邮政编码

术语地理编码通常是指将人类可读的地址转换为地图上的位置.反过来做的过程，将地图上的位置翻译成人类可读的地址，是称为反向地理编码.

地理编码 API 支持直接使用 latlng 进行反向地理编码范围.例如，以下查询包含布鲁克林某个位置的纬度/经度值:

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true_or_false

此查询返回以下结果:

{"状态": "好的",结果": [ {类型":街道地址，"formatted_address": "275-291 Bedford Ave, Brooklyn, NY 11211, USA",address_components":[ {"long_name": "275-291","short_name": "275-291",类型":street_number}, {"long_name": "贝德福德大街","short_name": "贝德福德大街",类型":路线}, {"long_name": "纽约","short_name": "纽约",类型":[地方"，政治"]}, {"long_name": "布鲁克林","short_name": "布鲁克林","类型": [ "administrative_area_level_3", "political"]}, {"long_name": "国王","short_name": "国王","类型": [ "administrative_area_level_2", "political"]}, {"long_name": "纽约","short_name": "纽约","类型": [ "administrative_area_level_1", "political"]}, {"long_name": "美国","short_name": "美国",类型":[国家"，政治"]}, {"long_name": "11211","short_name": "11211",类型":postal_code}],

I have a textbox, in which user will enter a Landmark and I have to retrieve a postal code of that landmark. I have no idea how to complete this task. I need some assisstance

解决方案

Google is your best bet. Use Reverse Geocoding (Address Lookup) on Google Map API to retrieve the postal code

The Geocoding API supports reverse geocoding directly using the latlng parameter. For example, the following query contains the latitude/longitude value for a location in Brooklyn:

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true_or_false

This query returns the following result:

{
  "status": "OK",
  "results": [ {
    "types": street_address,
    "formatted_address": "275-291 Bedford Ave, Brooklyn, NY 11211, USA",
    "address_components": [ {
      "long_name": "275-291",
      "short_name": "275-291",
      "types": street_number
    }, {
      "long_name": "Bedford Ave",
      "short_name": "Bedford Ave",
      "types": route
    }, {
      "long_name": "New York",
      "short_name": "New York",
      "types": [ "locality", "political" ]
    }, {
      "long_name": "Brooklyn",
      "short_name": "Brooklyn",
      "types": [ "administrative_area_level_3", "political" ]
    }, {
      "long_name": "Kings",
      "short_name": "Kings",
      "types": [ "administrative_area_level_2", "political" ]
    }, {
      "long_name": "New York",
      "short_name": "NY",
      "types": [ "administrative_area_level_1", "political" ]
    }, {
      "long_name": "United States",
      "short_name": "US",
      "types": [ "country", "political" ]
    }, {
      "long_name": "11211",
      "short_name": "11211",
      "types": postal_code
    } ],
