我正在写一个连接到Web服务应用程序,我不希望它等待太久,如果它不能得到一个连接.因此,我设置了httpparams的connectionTimeout.但它似乎没有任何影响.

测试我暂时关闭我的WLAN.该应用程序试图连接相当长的一段时间(超过秒3我想办法更多),然后抛出一个UnknownHostException.

这是我的代码:

try{
    HttpClient httpclient = new DefaultHttpClient();
    HttpParams params = httpclient.getParams();
    HttpConnectionParams.setConnectionTimeout(params, 3000);
    HttpConnectionParams.setSoTimeout(params, 3000);

    httppost = new HttpPost(URL);
    StringEntity se = new StringEntity(envelope,HTTP.UTF_8);
    httppost.setEntity(se);
    //Code stops here until UnknownHostException is thrown.
    BasicHttpResponse httpResponse = (BasicHttpResponse) httpclient.execute(httppost);

    HttpEntity entity = httpResponse.getEntity();
    return entity;

}catch (Exception e){
    e.printStackTrace();
}

任何人都有我想念的想法吗？
