在Android中,HTTP通信可以用Volley,在Java中不能使用Volley,只能使用DefaultHttpClient,HttpPost和HttpResponse。
/*
* 向服務器發送數據,並接受返回的數據
*/
public static String send2Server(String url, List <NameValuePair> params){
String res = null;
// 建立HTTPPost連接
HttpPost httpRequest = new HttpPost(url);
try
{
// 發出HTTP Request
httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
// 取得HTTP Response
HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);
res = EntityUtils.toString(httpResponse.getEntity());
}
catch (Exception e){
e.printStackTrace();
}
return res;
}
