Android 如何 post json格式的資料，並附加http頭，接受返回資料，請看下面的代碼：

 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頭資訊 7             httppost.addHeader("Authorization", "your token"); // 認證token 8             httppost.addHeader("Content-Type", "application/json"); 9             httppost.addHeader("User-Agent", "imgfornote");10             // http post的json資料格式： {"name": "your name","parentId":11             // "id_of_parent"}12             JSONObject obj = new JSONObject();13             obj.put("name", "your name");14             obj.put("parentId", "your parentid");15             httppost.setEntity(new StringEntity(obj.toString()));16             HttpResponse response;17             response = httpclient.execute(httppost);18             // 檢驗狀態代碼，如果成功接收資料19             int code = response.getStatusLine().getStatusCode();20             if (code == 200) {21                 String rev = EntityUtils.toString(response.getEntity());// 返回json格式：22                                                                         // {"id":23                                                                         // "27JpL~j4vsL0LX00E00005","version":24                                                                         // "abc"}25                 obj = new JSONObject(rev);26                 String id = obj.getString("id");27                 String version = obj.getString("version");28             }29         } catch (ClientProtocolException e) {30         } catch (IOException e) {31         } catch (Exception e) {32         }33     }

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