android - ksoap2 : java. lang.IllegalArgumentException : size <= 0 while making a http. 调用

Question

我想使用 Ksoap2 将我的 Android 4.03 设备连接到基于 dot.net 的 Web 服务。

我的问题是当我调用 soap 请求时出现异常:

11-16 08:35:08.649: W/System.err(6392): java.lang.IllegalArgumentException: size <= 0
11-16 08:35:08.649: W/System.err(6392): at java.io.BufferedInputStream.<init>(BufferedInputStream.java:94)
11-16 08:35:08.649: W/System.err(6392): at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:226)

11-16 08:35:08.649: W/System.err(6392):     at at.jesenko.eDoc.MainActivity$1.run(MainActivity.java:48)

我正在使用的代码

    final String url = "http://server:9007/DWService?wsdl";
    final String NAMESPACE = "http://tempuri.org/";
    final String METHOD_NAME ="Login";
    final String SOAP_ACTION="http://tempuri.org/Login";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Thread loginThread = new Thread(){

            @Override
            public void run() {

                try {


                    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
                    Request.addProperty("userName", "demo");
                    Request.addProperty("password", "demo1234");
                    Request.addProperty("organization", "Peters Engineering");

                    SoapSerializationEnvelope Envelope = new SoapSerializationEnvelope(
                            SoapEnvelope.VER12); 
                    Envelope.dotNet=true;
                    Envelope.setOutputSoapObject(Request);


                    HttpTransportSE ht = new HttpTransportSE(url);
                    ht.debug = true;
                    ht.call(SOAP_ACTION, Envelope);

                    SoapObject response = (SoapObject) Envelope.getResponse();
                    final String SessionID = response.getProperty("SessionID").toString();


                runOnUiThread(new Runnable() {

                    public void run() {

                        TextView tv = (TextView) findViewById(R.id.textView1);
                        tv.setText(SessionID);

                    }
                });

                } catch (Exception e) {

                    e.printStackTrace();

                }   

            }


    };
    loginThread.start();
}

这是我要调用的 wsdl 文件的一部分:

<wsdl:definitions name="DWService" targetNamespace="http://tempuri.org/">
 <wsdl:types>
  <xsd:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
   <xsd:element name="Login">
    <xsd:complexType>
     <xsd:sequence>
      <xsd:element minOccurs="0" name="userName" nillable="true" type="xsd:string"/> 
      <xsd:element minOccurs="0" name="password" nillable="true" type="xsd:string"/>
      <xsd:element minOccurs="0" name="organization" nillable="true" type="xsd:string"/> 
     </xsd:sequence>
    </xsd:complexType>
   </xsd:element>

我对 Ksoap 和 Web 服务没有太多经验，所以我希望有人能帮我解决这个问题:)

问候。

我尝试改用 ?svc -> 同样的错误 :(

这里的 WSDL 文件头可能是我的命名空间是假的

希望你能帮助我；)

使用 Fiddler 跟踪流量。可能服务器/服务正在返回 Content-Length: 0这可以是任何东西，在我的例子中，它是从客户端应用程序发送的 Content-type 不匹配和服务器端的预期内容类型。由于异常清楚地表明 ByteArrayInputStream 从服务接收了长度 <= 0 的内容。

我希望这会让您进行更多调查。

干杯，
