到了一個較陌生的環境，經常會在周邊找一些基礎設施，比如銀行，商場，餐廳等（還有一種更急切的是找廁所）。通過百度提供的地圖API，可以在你的應用中簡單做到，詳情可閱讀
Place API。我們以查找周邊銀行作為示例，需確定的參數至少有三個，要查找的位置的經度和緯度，需要查找的內容的類型或是關鍵字。
public String getPalace(String query,String lat,String lng) throws ClientProtocolException, IOException{
HttpClient httpClient = new DefaultHttpClient();
String url = palceRequestUrl(query,lat,lng);
logger.log(Level.INFO, url);
HttpGet httpget = new HttpGet(url);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpClient.execute(httpget, responseHandler);//位置xml
logger.log(Level.INFO,"baidu response:"+responseBody);
return responseBody;
}
public String palceRequestUrl(String query,String lat,String lng) throws UnsupportedEncodingException {
String url = WeChatConstant.BASEURL + "place/search?query=" + URLEncoder.encode(query,"UTF-8") + "&key="
+ WeChatConstant.MAPKEY +"&location="+lat+","+lng +"&radius=2000"+"&output=" + WeChatConstant.OUTPUTFORMAT;
return url;
}
Junit測試
@Test
public void testGetBaiduPlace() throws Exception{
BaiduMapService bms = new BaiduMapService();
String response = bms.getPalace("銀行", "39.915", "116.404");
List<BaiduPlaceResponse> list = BaiduPlaceResponse.getBaiduPlace(response);
for(BaiduPlaceResponse res:list){
System.out.println(res.toString());
}
}
