连接到REST服务的Android应用程序 - 连接被拒绝

Question

我正在开发一个涉及调用RESTful API的Android应用程序。我有用Python编写的REST服务，在我的笔记本电脑上（192.168.156.1）在端口8080上运行。我用Connectify Wifi连接将我的手机连接到我的笔记本电脑。电话号码是192.168.156.112。现在，我可以通过手机的浏览器使用URL（例如http://192.168.156.1:8080/lighting/12345）访问该服务。但是，当我尝试从应用程序访问它时，我在LogCat中遇到了“拒绝连接”错误。以下是我用来建立连接的代码。

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（）是将响应字符串传递回UI线程的方法。

任何帮助解决这个问题将是伟大的！提前致谢！

更新：增加堆栈跟踪

而且，这里是这样的服务器上运行的代码。

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) 

Answer 1

问题解决！我停止使用connectify热点并切换到我的手机和笔记本电脑现在连接的路由器。
