android - 在同一 Activity 中调用 Web 服务中的两种方法会出现异常

Question

我在同一 Activity 中调用两个网络服务时遇到了一个奇怪的问题。当我一个接一个地调用 Web 服务的两种方法时，给了我一个异常(exception)。一切都是正确的，我不知道问题所在。有人遇到过这个问题吗？请给我一些建议...

这是调用网络服务的代码:

   public static String getRelatedVideoResponse(String request, String url,
        String action, String method, String namespace, String value) {
    try {
         System.setProperty("http.keepAlive", "false");

        URL u = new URL(url);

        URLConnection uc = u.openConnection();
        HttpURLConnection connection = (HttpURLConnection) uc;

        connection.setRequestProperty("connection", "close");

        connection.setUseCaches(false);
        connection.setConnectTimeout(30000);
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestProperty("SOAPAction", action);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type",
                "text/xml;charset=UTF-8");

        OutputStream out = connection.getOutputStream();

        Writer wout = new OutputStreamWriter(out);

        wout.write(request);

        wout.flush();


        wout.close();
        Log.e("before buffer","buffer");

        BufferedReader rd = new BufferedReader(new InputStreamReader(
                connection.getInputStream()));
        Log.e("buffer",rd+"");
        Log.e("code...", connection.getResponseCode() + "");

        while ((StaticUtils.sRelResult = rd.readLine()) != null) {

            Log.e("result", StaticUtils.sRelResult);
            return StaticUtils.sRelResult;
        }

    } catch (MalformedURLException e) {

        e.printStackTrace();
    } catch (IOException e) {
        Log.e("error occured", "here");
        e.printStackTrace();
    }
    return StaticUtils.sRelResult;
}

Activity :

    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.searchvideos);
mHandler = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                // TODO Auto-generated method stub
                super.handleMessage(msg);
                switch (msg.what) {
                case SUCCESS:
                    s = "<tns:int xmlns:tns=\"http://schemas.microsoft.com/2003/10/Serialization/Arrays\">";
                    t = "</tns:int>";
                    buffer.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
                    buffer.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns=\"http://tempuri.org/\">");
                    buffer.append("<soap:Body><GetScoresForVideos><videoIDs>");
                    for (int i = 0; i < StaticUtils.sAlRelId.size(); i++) {
                        buffer.append(s + StaticUtils.sAlRelId.get(i) + t);
                    }
                    buffer.append("</videoIDs>");
                    buffer.append("</GetScoresForVideos></soap:Body></soap:Envelope>");
                    Log.e("bufer string", buffer.toString());
                    WsdlService s = new WsdlService();

                    s.getRelatedVideoResponse(buffer.toString(),
                            StaticUtils.URL, StaticUtils.RATE_ACTION,
                            StaticUtils.RATE_METHOD, StaticUtils.NAMESPACE, "");
break;
    }
        };

download();
}
private void download() {
        Runnable r = new Runnable() {

            public void run() {
                if (StaticUtils.checkNetworkStatus(getApplicationContext()) == true) {
                    WsdlService service = new WsdlService(
                            StaticUtils.NAMESPACE,
                            StaticUtils.RELATED_METHOD_NAME, StaticUtils.URL,
                            StaticUtils.RELATED_SOAP_ACTION);
                    String str = service.getResponseById(Integer
                            .valueOf(videoId));

                    Log.e("Related videos", str);
                    RelatedParser parser = new RelatedParser(str);
                    parser.parseRelatedVideos();
                    onSuccessDownload();
                } else {
                    onFailureDownload();
                }

            }
        };
        Thread t = new Thread(r);
        t.start();

    }
public void onSuccessDownload() {
        mHandler.sendEmptyMessage(SUCCESS);
    }

异常(exception)是:

谢谢，

Answer 1

java.io.FileNotFoundException:http://192.80.62:48080/Services/v0.2.2/SampleService.svc?wsdl

仔细看，IP地址好像拼错了。您可能需要将其更改为 192.80.62.4:8080？
