带有json参数的POST请求Android

Question

我正在开发一个 Android 应用程序，我必须在其中向服务器发出 POST 请求，shell 中的请求应该是这样的：

curl -v -H "接受：应用程序/xml" -H "内容类型：应用程序/json" -X POST -d ' {"marca":{"user_id":"78","lugar_id": "2","tiempo":"20:20:20","distancia_recorrida":"300","velocidad_maxima":"20.8", "velocidad_media":"15.8", "desnivel":"100", "aceleracion ":"5.8", "fecha":"2027-11-28 13:32:30"}, "api_token":""}' nameOfSerVer

嗯，我的 Java 代码如下所示：

HttpClient httpclient = new DefaultHttpClient();  
                            HttpPost httppost = new HttpPost(NameOfServer); 

try{
String marca ="{\"user_id\":\""+settings.getInt("user_id",0)+"\",\"lugar_id\":\""+id_lugar+"\",\"tiempo\":\""+tiempo+"\"," +
                                "\"distancia_recorrida\":\""+distancia+"\",\"velocidad_maxima\":\""+round((b.getDouble("velMax")*3.6),2, BigDecimal.ROUND_UP)+"\"," +
                                        " \"velocidad_media\":" +
                                "\""+velocidad_media+"\", \"desnivel\":\""+round(b.getDouble("maxDescenso"), 2, BigDecimal.ROUND_UP)+"\"," +
                                        " \"aceleracion\":\""+round(b.getDouble("ac")/9.806, 2, BigDecimal.ROUND_UP)+"\"," +
                                " \"fecha\":\"2014-11-28 13:32:30\"}";



                                JSONObject json = new JSONObject();

                                json.put("marca", marca);
                                json.put("api_token",settings.getString("api_token", ""));
                                StringEntity se = new StringEntity(json.toString());  

                                se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                                httppost.setEntity(se);

                                HttpResponse response = httpclient.execute(httppost);  
                                HttpEntity responseEntity =response.getEntity();

                                Log.e("USER", EntityUtils.toString(responseEntity).trim());
    } catch (UnsupportedEncodingException e) {
                                // TODO Auto-generated catch block
                                Log.e("USER", e.getMessage());
                            } catch (ClientProtocolException e) {
                                // TODO Auto-generated catch block
                                Log.e("USER", e.getMessage());
                            } catch (IOException e) {
                                // TODO Auto-generated catch block
                                Log.e("USER", e.getMessage());
                            } catch (JSONException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }  

它可以在命令 shell 中完美运行，但是从手机发送请求时，我得到 NOT AUTHORIZED

任何帮助将不胜感激。

谢谢！

我已经完成了一个好用户建议我的事情，这就是我得到的：

“\”出现在发布请求中很奇怪，而在处理代码时......它们来自一个字符串，应该忽略它们......不是吗？

在这个问题上仍然完全盲目......

Answer 1

就是这样，错误在：

String marca ="{\"user_id\":\""+settings.getInt("user_id",0)

服务器只接受字符串...并且它被解析为一个 int。

谢谢大家！ :)
