在POST

Question

我正在使用带有POST的自定义api的azure web服务，如下所示：

 mClient = new MobileServiceClient(
                "Your web service",
                "niHVXXnRXOGVGnvEMvImMIdgnraflH99",
                this).withFilter(new ProgressFilter());
 loadData();

 private void loadData() {
    ArrayList<Pair<String ,String>> bodyParams = new ArrayList<Pair<String, String>>();
    bodyParams.add(new Pair<String, String>("username","xyz@gmail.com"));
    bodyParams.add(new Pair<String, String>("password","qwertyuiop"));
    bodyParams.add(new Pair<String, String>("displayname","your name"));
    bodyParams.add(new Pair<String, String>("phonenumber","9745893297"));
    bodyParams.add(new Pair<String, String>("phoneIMEI","356938035643809"));
    bodyParams.add(new Pair<String, String>("isindividualgroup","false"));
    bodyParams.add(new Pair<String, String>("firmName",""));
    bodyParams.add(new Pair<String, String>("address1",""));
    bodyParams.add(new Pair<String, String>("phone1",""));
    bodyParams.add(new Pair<String, String>("city","Pune"));
    bodyParams.add(new Pair<String, String>("state","Maharashtra"));
    bodyParams.add(new Pair<String, String>("countryId","2"));
    bodyParams.add(new Pair<String, String>("zipCode",""));
    bodyParams.add(new Pair<String, String>("offeringiD","1004bca1-d45f-4da5-8608-199f380b6725"));
    bodyParams.add(new Pair<String, String>("numberOfLicense","0"));


    mClient.invokeApi("CustomRegistration", null, "POST", null, bodyParams, new ServiceFilterResponseCallback() {
        @Override
        public void onResponse(ServiceFilterResponse response, Exception exception) {
            if(exception!= null)
            {
                exception.printStackTrace();
            }
            else {
                System.out.println("RESPONSE : " + response.getContent());
            }
        }
    });

}

当我在设备上运行它时会发出如下错误：

com.microsoft.windowsazure.mobileservices.MobileServiceException: {"$id":"1","message":"An error has occurred."}

任何人都可以告诉我这是什么问题吗？ 我非常确定URL是正确的，参数是正确的，但没有得到响应。 请帮帮我。
