Question

json怎么解析啊？怎么得到具体数据啊？

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
String tel=request.getParameter("tel");
URL url=new URL("http://apistore.baidu.com/microservice/mobilephone?tel="+tel);
HttpURLConnection connection=(HttpURLConnection) url.openConnection();//打开链接
BufferedReader br=new BufferedReader
(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder sb=new StringBuilder();
while((line=br.readLine())!=null){
sb.append(line);
}
System.out.println(sb.toString());
}

sb里面数据是{"errNum":0,"errMsg":"success","retData":{"telString":"15250471390","province":"\u6c5f\u82cf","carrier":"\u6c5f\u82cf\u79fb\u52a8"}}
我想得到 telString ，province ， carrier ，具体怎么写代码啊？？

Answer 1

1、在网上找一个json处理包，json-lib.jar

2、JSONObject json = new JSONObject();
json = JSONObject.fromObject(sb);
String telString = json.getJSONObject("retData") .getString("telString ");
String province = json.getJSONObject("retData") .getString("province ");
String carrier = json.getJSONObject("retData") .getString("carrier ");
