在 Android 中使用 KSOAP2 发送 SOAP 消息

Question

您好，我正在尝试使用 KSOAP2 2.6.2 android 程序集连接到部署在 glassfish 3.1.1 上的 java WebService。从我的安卓程序。 这是我的命名空间

public static final String SERVICE_NAMESPACE = "za.co.n7.mobilebackup";
public static final String SERVICE_URL = "http://ipaddress:8080/MobileBackupServiceImplService/MobileBackupServiceImpl/";

这是我的发送方法

    final String METHOD_NAME = "Login";
    SoapObject results = null;
    SoapObject request = null;
    HttpTransportSE loginHttpTransport = null;
    try {
        request = new SoapObject(MBUtil.SERVICE_NAMESPACE, METHOD_NAME);
        request.addProperty("username", username);
        request.addProperty("password", MBUtil.hashPassword(password));

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.bodyOut=request;
        envelope.enc = SoapSerializationEnvelope.ENC;
        envelope.env="http://schemas.xmlsoap.org/soap/envelope/";

        // Web method call
        loginHttpTransport = new HttpTransportSE(MBUtil.SERVICE_URL);
        loginHttpTransport.debug = true;
        loginHttpTransport.call(MBUtil.SERVICE_URL + METHOD_NAME, envelope);

        results = (SoapObject) envelope.getResponse();

        System.out.println("Received Result without issue");

    } catch (Exception e) {
        e.printStackTrace();
        System.out.println(loginHttpTransport.requestDump);
        System.out.println(loginHttpTransport.responseDump);
    } finally {
        finish();
    }

我在 DDMS LogCat 中收到以下错误。

我已经复制了我的 SOAP 消息并将其粘贴到soapUI 中，它得到了结果。谁能帮助我，我已经为此苦苦挣扎了几个小时。 这是我的 SOAP 消息的示例

<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
  <v:Header/>
  <v:Body>
      <n0:Login id="o0" c:root="1" xmlns:n0="za.co.n7.mobilebackup">
         <username i:type="d:string">umohduke</username>
         <password i:type="d:string">c4066ed69b81d6b2b25f76405195c83ddaeecd8dbd3866f17912b895a72bc059</password>
      </n0:Login>
   </v:Body>
</v:Envelope>

Answer 1

试试这个方法：

使用 Android 向网络服务器发送文件。

FileInputStream fileInputStream = null;
try {
    fileInputStream = new FileInputStream(image);
} catch (FileNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
}

bitmap=BitmapFactory.decodeStream(fileInputStream);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] data = baos.toByteArray();
IMAGE= Base64.encodeBytes(data);
Log.e("THE IMAGE BYTES",""+IMAGE);

图片是要发送到网络服务器的字符串。

Answer 2

我不确定，但试试这个：

public static final String SERVICE_NAMESPACE = "http://za.co.n7.mobilebackup";

而不是

public static final String SERVICE_NAMESPACE = "za.co.n7.mobilebackup";
