创建json
- public String jsonTest() throws JSONException{
- JSONObject json=new JSONObject();
- JSONArray jsonMembers = new JSONArray();
- JSONObject member1 = new JSONObject();
- member1.put("loginname", "zhangfan");
- member1.put("password", "userpass");
- member1.put("email","10371443@qq.com");
- member1.put("sign_date", "2007-06-12");
- jsonMembers.put(member1);
-
- JSONObject member2 = new JSONObject();
- member2.put("loginname", "zf");
- member2.put("password", "userpass");
- member2.put("email","8223939@qq.com");
- member2.put("sign_date", "2008-07-16");
- jsonMembers.put(member2);
- json.put("users", jsonMembers);
-
- return json.toString();
- }
解析json
流中获取(如果是以流方式)：
BufferedReader br = new BufferedReader(new InputStreamReader((ServletInputStream) request.getInputStream()));
String line = null;
StringBuffer sb = new StringBuffer();
while ((line = br.readLine()) != null) {
sb.append(line);
}
//获取名为rules的Json
JSONObject jsonObject = new JSONObject().getJSONObject(sb.toString());
//将JSON转化成数组
JSONArray jsonArray = jsonObject.getJSONArray("Key");
- public String jsonTest2() throws JSONException{
- String jsonString="{\"users\":[{\"loginname\":\"zhangfan\",\"password\":\"userpass\",\"email\":\"10371443@qq.com\"},{\"loginname\":\"zf\",\"password\":\"userpass\",\"email\":\"822393@qq.com\"}]}";
- JSONObject json= new JSONObject(jsonString);
- JSONArray jsonArray=json.getJSONArray("users");
- String loginNames="loginname list:";
- for(int i=0;i<jsonArray.length();i++){
- JSONObject user=(JSONObject) jsonArray.get(i);
- String userName=(String) user.get("loginname");
- if(i==jsonArray.length()-1){
- loginNames+=userName;
- }else{
- loginNames+=userName+",";
- }
- }
- return loginNames;
- }
