POST請求帶有json參數的Android

Question

我正在開發一個Android應用程序，我必須向服務器發出POST請求，shell中的請求應該是這樣的：

curl -v -H“Accept：application / xml”-H“Content-type：application / json”-X POST -d'{“marca”：{“user_id”：“78”，“lugar_id”：“2” “蒂恩波”： “二十時20分20秒”， “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

好吧，我的Java代碼看起來像：

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();
                            }  

它在命令shell中運行良好，但是當從手機發送請求時，我得不到授權

任何幫助將非常感激。

謝謝！

我做了一個很好的用戶建議我，這是我得到的：

奇怪的是，“\\”出現在帖子請求中，而參加代碼......他們來自一個字符串，應該忽略它們......不是嗎？

在這個問題上仍然完全失明......

Answer 1

就是這樣，錯誤發生在：

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

服務器只接受字符串...並將其解析為int。

謝謝大家！ :)
