Android：连接到本地主机上的服务器时连接超时设备

Question

我无法弄清楚为什么会发生这种情况。我正在使用PHP服务器并将数据从Android应用程序发布到服务器。当我使用模拟器时，所有的东西都能正常工作，但是当我使用我的Android设备进行测试时，我收到了连接超时错误。我使用的是我的服务器在Android设备上的同一网络。我在这里贴上我的控制台日志，这样，就可以得到这方面一个明确的想法：

这里是我的JSON代码：

String url = "http://10.0.2.2/insert_user_details.php"; 
       HttpClient client = new DefaultHttpClient(); 
       HttpParams params = client.getParams(); 
       HttpConnectionParams.setConnectionTimeout(params, 15000); 
       HttpPost httpPost = new HttpPost(url); 
       httpPost.setHeader("json", jsonObject.toString()); 
       StringEntity se = null; 
       se = new StringEntity(jsonObject.toString()); 
       se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, 
         "application/json")); 
       httpPost.setEntity(se); 
       HttpResponse response = client.execute(httpPost); 
       int i = response.getStatusLine().getStatusCode(); 
       Toast.makeText(getBaseContext(), "Status: " + i, 
         Toast.LENGTH_LONG).show(); 

请帮我克服了这种怪异的局面。

Answer 1

首先，你应该看到，如何打开本地主机在Android设备上。 因为在您的Android设备上，您无法正常访问本地主机。

Answer 2

尝试增加连接超时......

HttpParameters = new BasicHttpParams(); 
HttpConnectionParams.setSoTimeout(httpParameters, timeoutConnection + 10000); 
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
httpclient = new DefaultHttpClient(httpParameters); 

代码：所有的

   String url = "http://10.0.2.2/insert_user_details.php"; 
      HttpPost httpPost = new HttpPost(url); 
      HttpParams params = new BasicHttpParams(); 
      HttpConnectionParams.setConnectionTimeout(params, 15000); 
      HttpClient client = new DefaultHttpClient(params); 
      httpPost.setHeader("json", jsonObject.toString()); 
      StringEntity se = null; 
      se = new StringEntity(jsonObject.toString()); 
      se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); 
      httpPost.setEntity(se); 
      HttpResponse response = client.execute(httpPost); 
      int i = response.getStatusLine().getStatusCode(); 
      Toast.makeText(getBaseContext(), "Status: " + i, Toast.LENGTH_LONG).show();
