java - 从网络服务请求信息时未获得完整结果

Question

我有一个编写的 Web 服务，以及我编写的用于调用其方法之一的 java 方法。该服务返回一个 JSON 字符串。

由于 NDA 协议(protocol)，我无法在此处发布任何服务代码，但这也无关紧要，因为从服务本身激活该方法时，它会给出正确的结果。

基本上，java 代码会跳过数组中的第一个单元格。

这是原始结果(直接来自服务):

{"message":"Success","success":"1","Table" : [{"priceline" : "Price 1","percaret_price" : "1430.0000","total" : "757.9000","discount" : "-45.00"},{"priceline" : "Price 2","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "Price 3","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "Cash","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "MSRP","percaret_price" : "","total" : "","discount" : ""}]}

这是java代码的结果:

{"message":"Success","success":"1","Table" : [{"priceline" : "Price 2","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "Price 3","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "Cash","percaret_price" : "","total" : "","discount" : ""},{"priceline" : "MSRP","percaret_price" : "","total" : "","discount" : ""}]}

这是我的java代码(所有变量都是正确的。如果不正确，则不会返回结果):

    SoapObject request = new SoapObject(NAMESPACE, COST_INFORMATION_NAME);
// Use this to add parameters
request.addProperty("user_id", login.getUser_id());
request.addProperty("company_id", login.getCompany_id());
request.addProperty("inventoryID", inventoryId);

// Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;

try {
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    // this is the actual part that will call the webservice
    androidHttpTransport.call(COST_INFORMATION_ACTION, envelope);

    // Get the SoapResult from the envelope body.
    SoapObject result = (SoapObject) envelope.bodyIn;
    if (result != null) {
    String res = result.getPropertyAsString(0);
            //************************************************************
            //Everything else isn't relevant, the res variable contains the result I put above the code.
            //************************************************************

感谢您的帮助!

不敢相信...服务中的 inventoryID 属性不是大写字母...奇怪的是，它使结果错误，而不仅仅是给出错误..
