Android使用HttpURLconnection时getInputStream出现超时

Question

代码如下：
public void getRequest(final String urlPath){
new Thread(){
public void run(){
try{
URL url = new URL(urlPath);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
con.setReadTimeout(5*1000);
con.setConnectTimeout(5*1000);
con.setDoInput(true);
con.setDoOutput(true);
con.setRequestMethod("POST");
con.setUseCaches(false);
con.setRequestProperty("Content-type","application/x-www-form-urlencoded");
con.setRequestProperty("Content-type",String.valueOf(data.length));
OutputStream outputStream = con.getOutputStream();
outputStream.write(data);
con.connect();
outputStream.flush();
outputStream.close();
con.getInputStream();
int response = con.getResponseCode();
if(response ==HttpURLConnection.HTTP_OK){
Message false_message = new Message();
false_message.what = 100;
handler.sendMessage(false_message);
con.disconnect();
}else {
Message false_message = new Message();
false_message.what = 101;
handler.sendMessage(false_message);
con.disconnect();
}
}catch (Exception e){
e.printStackTrace();
Message false_message = new Message();
false_message.what = 102;
handler.sendMessage(false_message);
}
}
}.start();
}

    在 con.getInputStream()时会出现Java.net.SocketTimeoutException
    但是实际上在服务器上是已经收到了我发送的信息
    所以这是为什么呢？？？

Answer 1

服务器收到数据后有没有返回一个response，200等来表示ok。这样客户端才能知道成功
