Question

我有一个简单的登录表单，它只使用HttpPost连接到服务器并接收一些数据。它在模拟器上运行正常，但在设备上会抛出 java.net.SocketException: Socket closed 。我希望对可能出现的问题有任何帮助。

如果我使用 HttpGet （并更改服务器端以接收GET），它可以正常工作。
INTERNET 权限包含在清单
url ＆amp; nameValuePairs 从 doInBackground 方法（AsyncTask）传递
url没有问题（在预期的浏览器或模拟器中工作）
不 localhost
模拟器和设备都使用API 10

此行导致问题： HttpResponse response = httpclient.execute(httppost);

设备是否可能以某种方式导致问题？（尚未在其他设备上测试过）
org.apache.http.client.methods.HttpPost 是否可以替代发布数据？

如果需要更多信息，请与我们联系。谢谢你的时间

方法：

static HttpClient httpclient = new DefaultHttpClient();

public static String postRequest(String url, List<NameValuePair> nameValuePairs)
{
    String resp = "";
    HttpPost httppost = new HttpPost(url);

    try {
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        resp = IS2S.inputStreamToString(response.getEntity().getContent());
    }
    catch (ClientProtocolException e) {}
    catch (IOException e) {
        Log.e("666---" , e.getMessage());
           e.printStackTrace();
    }
    return resp;
}

对每封邮件使用flush()而不关闭。并且也只使用一个输出流。
