Question

我无法弄清楚为什么会这样。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，一切正常，但当我使用我的Android设备进行测试时，我收到连接超时错误。我正在使用我的服务器在Android设备上的相同网络。我在这里粘贴我的控制台日志，以便您可以清楚地了解这一点：

这是我的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();

请帮助我克服这种奇怪的情况。

尝试增加连接超时...

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

您的代码：

                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();

首先，您应该看到如何在Android设备上打开本地主机。因为在您的Android设备上，您无法正常访问本地主机。

Android：连接到localhost上的服务器时设备上的连接超时
