服务器端接收客户端发来的json对象,解析该json对象的数据后,再给客户端反送一个封装了新的数据的json对象
PublicclassActionextendsActionSupportimplementsServletRequestAware,ServletResponseAware{
privateStringJson;
privateintage;
privateStringname;
privateStringpassword;
privateHttpServletRequestrequest;
privateHttpServletResponseresponse;
publicvoidexecute()
{
try{
JSONObjectobj=newJSONObject(this.getJson())
this.setAge(obj.getInt("age"));
this.setName(obj.getString("name"));
this.setPassword(obj.getString("password"));
}catch(org.json.JSONExceptione)
{
e.printStack();
}
JSONObjectobject=newJSONObject();
object.put("age",22);
object.put("name",nikerlover);
object.put("password",12345);
JSONObjecttem=newJSONObject();//若需要传递数组,夹杂其他的杂项,可以用Mapmap=newHashMap<String,Object>()将数据封装好,创建List<Map<String,Object>>
list=newArrayList<Map<String,Object>>(),然后,list.add(map);再用JSONObject进行封装,JSONObject和JSONArray可以相互嵌套,你懂的
JSONObjecttemp=newJSONObject();
try{
tem.put("user",object);
temp.put("json",tem);
response.setCharacterEncoding("UTF-8");
response.getWriter().write(temp.toString());
}catch(Exceptione)
{
e.printStackTrace();
}
}
//GetterandSettermethod
//publicvoidsetServletResponse(HttpServletResponse)
}
Android客户端:先给服务器发送一个封装好了的JSON对象,再等待服务器反送response对象,将response里的JSON对象获取并解析
pubicvoidOnCreate(Handlerinstance)
{
StringUrl="http://59.64.34.45/project/index.action";
HttpClientclient=newDefaultHttpClient();
HttpPostpost=newHttpPost(url);
List<NameValuePair>pair=newArrayList<NameValuePair>()'
try{
JSONObjectobj=newJSONObject();
obj.put("age",2);
obj.put("name",nikerlover);
obj.put("password",45667);
JSONObjectjson=newJSONObject();
pair.add(newBasicValueNamePair("json",obj.toString()));
post.setEntity(newUrlEncodedFormEntity(pair,HTTP.UTF_8));
HttpResponseresponse=client.execute(post);
if(response.getStatusLine().getStatusCode()==200)
{
StringresponseStr=EntityUtils.toString(response.getEntity());
JSONObjectjson=newJSONObject(responseStr).getJSONObject("json");
JSONObjectobject=json.getJSONObject("user");
intAge=obj.getInt("age");
StringName=obj.getString("name");
StringPassword=obj.getString("password");
}
}
}
