我正在尝试使用我的 Android 手机上的 REST 访问服务器的 Web 服务（我在网络内部）。在路由器中，我已经完成了“路由”以从外部访问所有查询，但路由器具有用户名和密码。

我的问题是是否有必要在 HTTP Post 或 HTTP 客户端中添加一些代码来访问我的路由器，因为所有连接都给了我HttpHostConnectException: Connection to http://myipaddress:myport refused

我尝试了一些代码，但这没有用。

@Override
protected Void doInBackground(Object... params) {
    kkk = ((Integer) params[2]);

    parametros = params;
    Log.i("SendOnlyOneFact", "Guardando datos de la actividad " + kkk);

    Thread.currentThread().setName("NA_SendOnlyOneFact-" + kkk);
    // Guardar los datos creados
    getActividades().get(kkk).saveData((android.app.Activity) params[1]);
    // Serializar los datos creados
    String cosa_serializada = getActividades().get(kkk).getMeasure()
            .serializeData(getActividades().get(kkk), (android.app.Activity) params[1]);

    // Obtener el XML a partir de ese arraylist
    // Enviarlo mediante REST
    HttpHost targetHost = new HttpHost(((GateDefinition) params[0]).getServer(),
            ((GateDefinition) params[0]).getPort(), "http");

    HttpPost httpPost = new HttpPost("http://" + ((GateDefinition) params[0]).getServer() + ":"
            + ((GateDefinition) params[0]).getPort() + "/" + ((GateDefinition) params[0])
            .getWeb_service());
    // Also be sure to tell the server what kind of content we are sending
    httpPost.setHeader("content-type", "text/plain");

    // Something like this, but this doesn't work :(
    ArrayList<NameValuePair> nvps = new ArrayList<NameValuePair>();
    nvps.add(new BasicNameValuePair("login", "1234"));
    nvps.add(new BasicNameValuePair("password", "1234"));
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nvps, "UTF_8"));
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        StringEntity entity = new StringEntity(cosa_serializada, "UTF-8");
        entity.setContentType("text/plain");
        httpPost.setEntity(entity);

        // execute is a blocking call, it's best to call this code in a
        // thread separate from the ui's
        response = httpClient.execute(targetHost, httpPost);
    } catch (SocketException ex) {
        Log.e("SendOnlyOneFact", "No existe conexión con el servidor");
        ex.printStackTrace();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return null;
}

编辑：我用数据连接测试它并且它可以工作，但是用wifi它给了我这个例外，我不知道为什么！:o
