定制型Htt presponse于Android到PHP一个POST之后 [英] custom HttpResponse after a POST from Android to PHP

问题描述

我有perfom一个POST到PHP页面类，这个页面应该与数据发布的一些动作，并返回结果（像OK，KO）。我怎样才能把结果发送回PHP，以及如何使用它在android系统？

I have a class that perfom a POST to a php page, this page should make some action with the posted data, and return the result (something like OK, KO). how can I send the result back in PHP, and how I use it in android?

在Android身边，我已经得到了这一点，这发布数据：

on the Android side i've got this, which post the data:

public int postData(String id, String webrispid, String userid) {
            // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://www.server.com/postpage.php");
            int responseCode = 0;
            try {
                // Add your data
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                nameValuePairs.add(new BasicNameValuePair("id", id));               
                nameValuePairs.add(new BasicNameValuePair("user", userid));
                nameValuePairs.add(new BasicNameValuePair("webrisid", webrispid));
                try {
                    nameValuePairs.add(new BasicNameValuePair("token",AeSimpleSHA1.SHA1(userid) ));
                } catch (NoSuchAlgorithmException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);
                responseCode = response.getStatusLine().getStatusCode();
                System.out.println(response);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }
            return responseCode;
        }

和实际的postpage.php看起来是这样的：

and actually the postpage.php looks like this:

<?php

if ( isset($_POST['user']) ) {
// try to store the data posted

//if data is stored return "ok"

// else return "ko"

} else {
// error
}
?>

所以在Android方面，我应该停止发送相同的数据并开始处理数据的其余部分，并最终将其发送到网页...

so on the android side, i should stop sending the same data and start process the rest of data and eventually send it to the page...

推荐答案

如果它仅仅是OK或KO，你可以做到以下几点：

If it is just 'OK' or 'KO', you could do the following:

<?php
  if ( isset($_POST['user']) ) { // try to store the data posted
    //do some test
    echo "OK"; //or KO
  } else { 
    echo "ERROR"; 
  }
?>

Android的部分看起来是这样的：

The android part could look like this:

// Execute HTTP Post Request
String status = httpclient.execute(httpPost, new BasicResponseHandler());
System.out.println(status); //will be OK or KO or ERROR
