Android 如何 post json格式的数据，并附加http头，接受返回数据，请看下面的代码：

1.private void HttpPostData() {

2.try {

3. HttpClient httpclient = new DefaultHttpClient();

4. String uri = "http://www.yourweb.com";

5. HttpPost httppost = new HttpPost(uri);

6. //添加http头信息

7. httppost.addHeader("Authorization", "your token"); //认证token

8. httppost.addHeader("Content-Type", "application/json");

9. httppost.addHeader("User-Agent", "imgfornote");

10. //http post的json数据格式： {"name": "your name","parentId": "id_of_parent"}

11. JSONObject obj = new JSONObject();

12. obj.put("name", "your name");

13. obj.put("parentId", "your parentid");

14. httppost.setEntity(new StringEntity(obj.toString()));

15. HttpResponse response;

16. response = httpclient.execute(httppost);

17. //检验状态码，如果成功接收数据

18. int code = response.getStatusLine().getStatusCode();

19. if (code == 200) {

20. String rev = EntityUtils.toString(response.getEntity());//返回json格式： {"id": "27JpL~j4vsL0LX00E00005","version": "abc"}

21. obj = new JSONObject(rev);

22. String id = obj.getString("id");

23. String version = obj.getString("version");

24. }

25. } catch (ClientProtocolException e) {

26. } catch (IOException e) {

27. } catch (Exception e) {

28. }

29.}

主要用到的类有：org.apache.http.client.HttpClient 、org.apache.http.client.methods.HttpPost 和 org.json.JSONObject
