Android Ksoap2和WCF

我已经开发了一个WCF服务.NET4（SOAP），我正在尝试从Android上传文件。 使用.NET客户端可以很好地工作，但使用Android则不行，下面是我在Android中使用的代码

WCF服务接收数据时，流似乎为空（长度为零）

请帮帮我

public class WCFclient {
private static final String METHOD_NAME = "UploadFile";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.1.103/AndroidWCF/Service1.svc";
private static final String SOAP_ACTION = "http://tempuri.org/ITransferService/UploadFile";



public static String extractText(byte[] _data)

{
    @SuppressWarnings("unused")
    int lun = _data.length;

     SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
  MarshalBase64 marshal = new MarshalBase64();
     PropertyInfo p1=new PropertyInfo();
     p1.setName("request");
     p1.setType(_data);
     request.addProperty(p1);
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
     envelope.dotNet=true;
     envelope.encodingStyle = SoapSerializationEnvelope.XSD;
     envelope.setOutputSoapObject(request);
       marshal.register(envelope);
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, 20000);


     try {
        androidHttpTransport.call(SOAP_ACTION, envelope);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 
     SoapObject result = null;
    try {
        result = (SoapObject)envelope.getResponse(); 
    } catch (SoapFault e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
     String resultData=result.getProperty(0).toString();
    return resultData;

}

// Returns the contents of the file in a byte array.
    public static byte[] getBytesFromFile(File file) throws IOException {
        InputStream is = new FileInputStream(file);

        // Get the size of the file
        long length = file.length();

        // You cannot create an array using a long type.
        // It needs to be an int type.
        // Before converting to an int type, check
        // to ensure that file is not larger than Integer.MAX_VALUE.
        if (length > Integer.MAX_VALUE) {
            // File is too large
        }

        // Create the byte array to hold the data
        byte[] bytes = new byte[(int)length];

        // Read in the bytes
        int offset = 0;
        int numRead = 0;
        while (offset < bytes.length
               && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
            offset += numRead;
        }

        // Ensure all the bytes have been read in
        if (offset < bytes.length) {
            throw new IOException("Could not completely read file "+file.getName());
        }

        // Close the input stream and return bytes
        is.close();
        return bytes;
    }

这个问题已经被问过很多次了。 根据我的经验，当方法名称、名称空间、URI、Soap操作不正确时，就会出现此错误

您应该在SOAP\u操作中添加“”

private static final String SOAP_ACTION = "\"http://tempuri.org/ITransferService/UploadFile\"";

是否出现任何异常或错误？？请把错误信息贴出来。

private static final String SOAP_ACTION = "\"http://tempuri.org/ITransferService/UploadFile\"";
