android - java.net.SocketException : sendto failed: EPIPE (Broken pipe) while sending byte[] 异常

Question

我正在尝试上传通过安卓手机录制的视频。但是在将视频作为 byte[] 发送到服务器时出现以下错误:

  01-20 13:03:18.250: E/SaveMedia-response(4393): java.net.SocketException: sendto failed: EPIPE (Broken pipe)

这是我尝试上传视频的方式:

        SoapObject request = new SoapObject(
                HelpMeConstant.WSDL_TARGET_NAMESPACE, "SaveMedia");
        Log.i("SaveMedia-parameter", "Email : " + Email + ", Media : " + Media
                + "MediaType : " + MediaType + ",MediaExt : " + MediaExt);

        MediaAvidance mediainfo = new MediaAvidance();
        mediainfo.EmailId = Email;
        mediainfo.Media = Media;
        mediainfo.MediaExt = MediaExt;
        mediainfo.MediaType = MediaType;

        PropertyInfo pi = new PropertyInfo();
        pi.setName("mediainfo");
        pi.setValue(mediainfo);
        pi.setType(mediainfo.getClass());

        request.addProperty(pi);
/*      request.addProperty("EmailId",Email);
         request.addProperty("Media", Media); 
         request.addProperty("MediaType", MediaType);
         request.addProperty("MediaExtn", MediaExt);
*/       
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        Log.i("SaveMedia","Serialising..");
        new MarshalBase64().register(envelope);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE httpTransport = new HttpTransportSE(
                HelpMeConstant.SOAP_ADDRESS);
        Object response = null;

        try {
            Log.i("SaveMedia","Calling service..");
            httpTransport.call(HelpMeConstant.SOAP_ACTION + "SaveMedia",
                    envelope);
            Log.i("SaveMedia","getting response..");
            response = envelope.getResponse();
        } catch (Exception exception) {
            response = exception.toString();
        }
        Log.i("response", response.toString());
        return response.toString();

它正在发送到如下所示的 .net Web 服务:

 [WebMethod]
    public string SaveMedia(MediaAvidance avidanceinfo)
    {
        rs = new ResultSet();
        rs = logictask.SaveMedia(avidanceinfo.EmailId,avidanceinfo.Media,avidanceinfo.MediaType,avidanceinfo.MediaExt);
        return rs.isSuccessfull;
    }

MediaAvidance:

public class MediaAvidance implements KvmSerializable {
    public String EmailId;
    public byte[] Media;
    public String MediaType;
    public String MediaExt;

    public MediaAvidance() {
    }

    public MediaAvidance(String EmailID, byte[] Media, String MediaType,
            String MediaExt) {

        this.EmailId = EmailID;
        this.Media = Media;
        this.MediaType = MediaType;
        this.MediaExt = MediaExt;
    }

    @Override
    public Object getProperty(int arg0) {
        switch (arg0) {
        case GETEMAILID:
            return EmailId;
        case GETMEDIA:
            return Media;
        case GETMEDIATYPE:
            return MediaType;
        case GETMEDIAEXT:
            return MediaExt;
        default:
            return null;
        }
    }

    @Override
    public int getPropertyCount() {
        // TODO Auto-generated method stub
        return 4;
    }

    @SuppressWarnings("rawtypes")
    @Override
    public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {
        switch (index) {
        case 0:
            info.type = PropertyInfo.STRING_CLASS;
            info.name = "EmailId";
            break;
        case 1:
            info.type = PropertyInfo.OBJECT_CLASS;
            info.name = "Media";
            break;
        case 2:
            info.type = PropertyInfo.STRING_CLASS;
            info.name = "MediaType";
            break;
        case 3:
            info.type = PropertyInfo.STRING_CLASS;
            info.name = "MediaExt";
            break;
        default:
            break;
        }

    }

    @Override
    public void setProperty(int index, Object value) {
        switch (index) {
        case 0:
            EmailId = value.toString();
            break;
        case 1:
            Media = (byte[]) value;
            break;
        case 2:
            MediaType = value.toString();
            break;
        case 3:
            MediaExt = value.toString();
            break;
        default:
            break;
        }
    }
}

在服务器端 MediaAvidance 类不实现 KvmSerializable 及其方法。

我搜索了几天，并在 stackoverflow 中解决了很多问题，并了解到我正在尝试在连接关闭时编写，而且它与套接字编程有关。但是

我不知道如何保持连接(我认为可能是一种解决方案)。请帮我。

谢谢，苏拉布

我终于成功了。发布此解决方案希望它对像我这样的人有用。您的代码中可能有更多或以下任何问题，但我很高兴犯这 3 个错误，并从中吸取教训，这是导致视频上传出现问题的原因:

1. 我已通过实现 KvmSerializable 在 android 中序列化了 MediaAvidance，但为了让它正常工作，您的服务器端 MediaAvidance 也必须序列化。我已经通过下面的代码解决了我遇到的 Cannot Serialize 异常:

   [Serializable]   public class MediaAvidance

您还需要将您的SoapSerializationEnvelope注册到MarshalBase64:

   envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);   new MarshalBase64().register(envelope); 

1. 当您从 android 调用时，在 PropertyInfo 中设置与您在服务方法参数中完全相同的名称(例如:avidanceinfo)，这个解决了 faultstring: 'Server was unable读取请求。异常:

   android中定义的属性名

   pi.setName("avidanceinfo");

   服务方式:

    [WebMethod] public string SaveMedia(MediaAvidance avidanceinfo)

2. 最后你需要添加envelope.implicitTypes = true ;
   这样 HttpTransportSE 将能够识别服务器上的 MediaAvidance 类型，否则您将得到 Object reference not set to an instance of an object。当使用 xs:anyType.... 异常。
