如何解决andriod的http连接需要花费2秒的问题

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://192.168.1.137:8880/form");

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
     Log.e(TAG,e.toString());
    } catch (IOException e) {
     Log.e(TAG,e.toString());
    }
}

 

通过以上的代码，打开一个http连接，花费了起码2秒钟，不知道为什么?正常的访问的话，只需要80ms就可以了，考虑下，采用HTTP1.1协议

HttpParams params = new BasicHttpParams();
params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
HttpClient httpclient = new DefaultHttpClient(params);

 

If I remember correctly, HTTP 1.0 opens a new TCP connection for every request. Does that explain the large delay?

如果我记得不错的话，http1.0协议为每个请求建立连接，这个也许可以解释为什么有这么长的延迟，

A HTTP POST request now takes between 50 and 150 ms over WLAN and something between 300 and 500 ms over 3G.

通常的话，一个post请求如果通过wlan网络请求的话大概需要花费50-150ms，如果通过3g可能需要300-500ms；
