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。它在模拟器上运行良好,但在设备上它会抛出java.net.SocketException: Socket closed
. 对于可能出现的问题,我将不胜感激。
- 如果我使用
HttpGet
(并将服务器端改为接收 GET)它工作正常。 INTERNET
权限包含在清单中url
&nameValuePairs
从doInBackground
方法(AsyncTask)传递- url 没有问题(在浏览器或模拟器中按预期工作)
- 这不是本地主机
- 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)
- 有没有其他方法可以
org.apache.http.client.methods.HttpPost
发布数据?
如果需要更多信息,请告诉我。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;
}
