百度地图之LBS云服务

1.1     LBS云服务  (百度提供的数据库)

        LBS.云是百度地图针对LBS开发者推出的平台级服务，结合已有的地图API和SDK服务，通过开放服务端存储和计算能力，提供海量位置数据（点、面数据）的实时存储、检索、展示一体化解决方案。

1.    创建AK

一定要使用服务端的密钥，只有服务端才支持云存储

2.       使用HttpClient发送http的请求

    publicvoid createTable() throwsClientProtocolException, IOException {

       HttpClient httpClient = HttpClients.createDefault();

       List<NameValuePair>nameValuePairs = newArrayList<NameValuePair>();      

       nameValuePairs.add(newBasicNameValuePair("name", "Test"));
