BaiduMapApi 与 GoogleMapApi geocoding信息 获取方法(用地名获取经纬度)

 Java代码 使用了 httpclient包
1.public String getGoogleLocation() throws ClientProtocolException, IOException
2.   {
3.      URIBuilder builder = new URIBuilder();
4.      builder.setScheme("http").setHost("maps.googleapis.com").setPath("/maps/api/geocode/xml")
5.          .setParameter("address",address+"南京"+"地铁站")
6.          .setParameter("sensor","false");
7.      URI uri = null;
8.      try {
9.         uri = builder.build();
10.         System.out.println(uri);
11.      } catch (URISyntaxException e) {
12.         // TODO Auto-generated catch block
13.         e.printStackTrace();
14.      }
15.      HttpGet httpget = new HttpGet(uri);
16.//'http.protocol.cookie-policy'：定义了用于HTTP状态管理的cookie规范的名字。这个参数期望得到一个java.lang.String类型的值。如果这个参数没有被设置，那么合法的日期格式就是CookieSpec实现规范的值。
17.      httpget.getParams().setParameter("http.protocol.cookie-policy",
18.            CookiePolicy.BROWSER_COMPATIBILITY);
19.
20.      HttpClient httpclient = new DefaultHttpClient();
21.      HttpResponse response = httpclient.execute(httpget);
22.      HttpEntity entity = response.getEntity();
23.      if (entity != null) {
24.
25.         String xml = EntityUtils.toString(entity);
26.         return xml;
27.      }
28.      return "";
29.   }
百度获取时参数如下
1.builder.setScheme("http").setHost("api.map.baidu.com").setPath("/geocoder/v2/")
2.    .setParameter("ak", ak)
3.    .setParameter("output",output)
4.    .setParameter("address",address)
5.    .setParameter("city",city);

可以看到google地图查询得出的结果更详细。而且一些站名在Baidu下面无法获取但是用google可以获取
