Android應用程序連接到REST服務-拒絕連接

Question

我正在開發一個涉及調用RESTful API的Android應用。 我有使用Python編寫的REST服務，該筆記本計算機在端口8080上的筆記本電腦（ 192.168.156.1 ）上運行。我通過Connectify Wifi連接將手機綁定到筆記本電腦。 電話位於192.168.156.112 。 現在，我可以通過手機的瀏覽器使用諸如http://192.168.156.1:8080/lighting/12345的URL來訪問該服務。 但是，當我嘗試從應用程序訪問它時，在LogCat中收到“連接被拒絕”錯誤。 以下是我用來建立連接的代碼。

    String sampleURL = "`http://192.168.156.1:8080/lighting/weert`";
        HttpClient Client = new DefaultHttpClient();
         try
         {
             HttpGet httpget = new HttpGet(sampleURL);
             String serverString = "";
             HttpResponse response= Client.execute(httpget);
             StatusLine statusLine = response.getStatusLine();
             if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
                 ByteArrayOutputStream out = new ByteArrayOutputStream();
                 response.getEntity().writeTo(out);
                 out.close();
                 serverString = out.toString();
             } 
             threadMsg(SetServerString);
          }
        catch(Exception ex){
            Log.e("RESTCALL",ex.getMessage());  
            threadMsg("Fail!");
         }

threadMsg（）是將響應字符串傳遞回UI線程的方法。

解決這個問題的任何幫助都將非常有用！ 提前致謝！

更新：添加堆棧跟蹤

另外，這是服務器上運行的代碼。

    import socket
    from bottle import route, run@route('/lighting/<name>', method='GET')

    def hello(name="ABC"):
    return name

    run(host='192.168.156.1', port=8080, debug=True)

問題解決了！ 我停止使用connectify熱點，並切換到路由器，現在我的手機和筆記本電腦已連接到該路由器。
