Android发布wcf服务请求

我发布数据从android到wcf服务，但获取错误请求错误使用HttpURLConnection。Android发布wcf服务请求

的Android代码：

`public User RegisterPost(Context context, User rUser) throws UnsupportedEncodingException{ 

    String url = context.getResources().getString(R.string.SERVICE_URL)+ "Signup"; 
    try 
    { 
     JSONObject userValue = new JSONObject(); 
     JSONObject user = new JSONObject(); 

     userValue.put("name", rUser.name); 
     userValue.put("email", rUser.email); 
     userValue.put("password", rUser.password); 
     userValue.put("phone", rUser.phone); 
     userValue.put("nic", rUser.nic); 
     userValue.put("userType", rUser.userType); 
     userValue.put("image", rUser.image); 

     user.put("user", userValue.toString()); 

     String response = postData(url, user); 

    } 
    catch(Exception ex) 
    { 
     ex.printStackTrace(); 
    } 
    return null; 
    }`

POSTDATA（）函数是在同一文件中。

public String postData(String urlpath, JSONObject json) 
    { 
    HttpURLConnection connection = null; 
    try { 
     URL url=new URL(urlpath); 
     connection = (HttpURLConnection) url.openConnection(); 
     connection.setDoOutput(true); 
     connection.setDoInput(true); 
     connection.setRequestMethod("POST"); 
     connection.setRequestProperty("Content-Type", "application/json"); 
     connection.setRequestProperty("Accept", "application/json"); 
     OutputStreamWriter streamWriter = new OutputStreamWriter(connection.getOutputStream()); 
     Log.d("write data",json.toString()); 
     streamWriter.write(json.toString()); 
     streamWriter.flush(); 
     StringBuilder stringBuilder = new StringBuilder(); 
     if (connection.getResponseCode() == HttpURLConnection.HTTP_OK){ 
      InputStreamReader streamReader = new InputStreamReader(connection.getInputStream()); 
      BufferedReader bufferedReader = new BufferedReader(streamReader); 
      String response = null; 
      while ((response = bufferedReader.readLine()) != null) { 
       stringBuilder.append(response + "\n"); 
      } 
      bufferedReader.close(); 

      Log.d("HTTP_OK response", stringBuilder.toString()); 
      return stringBuilder.toString(); 
     } else { 
      Log.e("else response", connection.getResponseMessage()); 
      return null; 
     } 
    } catch (Exception exception){ 
     Log.e("test", exception.toString()); 
     return null; 
    } finally { 
     if (connection != null){ 
      connection.disconnect(); 
     } 
    } 

}

json数据发送到服务;

{ 
"user": "{\"name\":\"rrr rrr\",\"email\":\"[email protected]\",\"password\":\"123\",\"phone\":\"12333333\",\"nic\":\"44444444\",\"userType\":\"Passenger\",\"image\":\"55akasdfadphpoijpiojasdfasdfasdfasdfasdfasdfasdfasdf\"}" 
}

这里是WCF服务代码;

[OperationContract] 
    [WebInvoke(Method = "POST", UriTemplate = "/Signup", 
       RequestFormat = WebMessageFormat.Json, 
       ResponseFormat = WebMessageFormat.Json)] 
    bool Signup(ReturnUserData user); 



public bool Signup(ReturnUserData user) 
    { 

     user usr = new user(); 
     usr.name = user.name; 
     usr.email = user.email; 
     usr.password = user.password; 
     usr.phone = user.phone; 
     usr.nic = user.nic; 
     usr.userType = user.userType; 
     usr.image = user.image; 
     db.users.Add(usr); 
     db.SaveChanges(); 
     return true; 
    } 


public class ReturnUserData 
{ 

    public string id { get; set; } 
    public string name { get; set; } 
    public string email { get; set; } 
    public string password { get; set; } 
    public string phone { get; set; } 

    public string userType { get; set; } 

    public string image { get; set; } 

}

当我用邮递员测试这项服务时，我得到了这个错误。 '服务器在处理请求时遇到错误。异常消息是'反序列化AlumniService.ReturnUserData类型的对象时发生错误。遇到无效字符''。'。查看服务器日志获取更多详细信异常堆栈跟踪是： ' –

最后我想通了什么是问题，我的RegisterPost()函数有一些错误的实现，所以我改变了函数。

public User RegisterPost(Context context, User rUser) throws UnsupportedEncodingException{ 

    String url = context.getResources().getString(R.string.SERVICE_URL)+ "Signup"; 
    try 
    { 
     JSONObject newUser = new JSONObject(); 
     newUser.put("name", rUser.name); 
     newUser.put("email", rUser.email); 
     newUser.put("password", rUser.password); 
     newUser.put("phone", rUser.phone); 
     newUser.put("nic", rUser.nic); 
     newUser.put("userType", rUser.userType); 
     newUser.put("image", rUser.image); 

     String response = postData(url, newUser.toString()); 
     Log.d("response", response); 

     if(response!="") 
     { 
      try { 
       JSONObject user = new JSONObject(response); 
       User returnUser = new User(user.getInt("id"),user.getString("name"),user.getString("email"),user.getString("password"),user.getString("phone"),user.getString("nic"),user.getString("userType"), user.getString("street"), user.getString("city"), user.getString("country"), Double.parseDouble(user.getString("lat")), Double.parseDouble(user.getString("lng")),user.getInt("is_login"),user.getInt("is_vehicle_added"), user.getString("reg_id"), user.getInt("isError"), user.getString("errorMessage"), user.getString("image")); 
       return returnUser; 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 

    } 
    catch(Exception ex) 
    { 
     ex.printStackTrace(); 
    } 
    return null; 
}
