Android版（Java）的HTTP POST JSON服务器，但是服务器告诉我没有POST变量被视为 [英] Android (Java) HTTP POST JSON to server, but the server tells me no POST variables were seen

问题描述

在我大学项目组的成员创造了这个PHP为我们的应用程序。

A member of my group project at university created this php for our application.

if ( $_SERVER['REQUEST_METHOD'] != 'POST' ) {
  header( 'HTTP/1.0 405 Method Not Allowed' );
  output( 2, 'only POST is accepted; received ' . $_SERVER['REQUEST_METHOD'], true );
}

# catch empty POST requests
if ( count( $_POST ) == 0 ) {
  output( 3,  'no POST variables were sent' );
}

我的code经过一次测试，但它始终是失败的第二个测试。与错误code'3''没有POST变量被送到

My code passes the first test, but it is always failing this second test. with the error code '3' 'no POST variables were sent'

这是Android code负责发送POST请求：

This is the android code responsible for sending the POST request:

public void uploadToServer(Vector<PointOfInterest> pois)  {

        try {
            JSONObject auth = new JSONObject();
            JSONObject walk = new JSONObject();
            JSONArray points = new JSONArray();




            walk.put("walk name", "TEST NAME");
            walk.put("walk desc short", "TEST SHORT");
            walk.put("walk desc long", "TEST LONG");


            for(int i = 0; i < pois.size(); i ++){

                JSONObject location = new JSONObject();
                location.put("name", pois.get(i).getName());
                location.put("timestamp", 0);
                location.put("lattitude",pois.get(i).getLattitude());
                location.put("longitude",pois.get(i).getLongitude());
                location.put("Description",pois.get(i).getDescription());

                points.put(location);

            }

            auth.put("data", walk);

            walk.put("locations", points);

            auth.put("authorization","");
            auth.put("hash","3b6decebf0bab0e0a08c18a94849d6df1e536d65");
            auth.put("salt", "dave");

            UploadASyncTask upload = new UploadASyncTask();
            upload.execute(auth);

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


private class UploadASyncTask extends AsyncTask<JSONObject, Void, Void>{

        @Override
        protected Void doInBackground(JSONObject...auth) {
            try{
                HttpClient httpclient = new DefaultHttpClient();

                HttpPost httpPost = new HttpPost("http://project.chippy.ch/upload.php");

                String json = "";

                json = auth.toString();

                StringEntity se = new StringEntity(json);
                se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                httpPost.setEntity(se);

                httpPost.setHeader("User-Agent", "WalkingTourCreator/1.0");
                httpPost.setHeader("Accept", "application/json");
                httpPost.setHeader("Content-type", "application/json");
                //httpPost.setHeader("data", json);

                HttpResponse httpResponse = httpclient.execute(httpPost);

                InputStream inputStream = httpResponse.getEntity().getContent();
                String result = "";

                if(inputStream != null){
                    result = convertInputStreamToString(inputStream);

                }
                else{
                    result = "Did not work!";

                }

                Log.d("RESULT", result);


            }catch(Exception e){

                Log.e("ERROR IN SEVER UPLOAD", e.getMessage());
            }
            return null;


        }

任何意见或任何明显的问题？

Any ideas, or any obvious problems?

谁做的PHP的人说这样的：

The guy who made the php said this:

后需要键 - 值对（据我可以告诉）;你需要发送的关键。用JSON作为内容的数据

"POST needs key-value pairs (as far as I can tell); you'll need to send a key of "data" with the JSON as the contents."

据我所知，没有我这样做呢？

As far as i am aware aren't i doing this?

我跟随了很多本网站的帖子和其他各种布洛格斯等，他们似乎都做类似的事情，以我在做什么。

I have followed a lot of posts on this site and various other bloggs etc, and they all seem to do a similar thing to what i am doing.

干杯
克里斯。

推荐答案

解决：

HttpParams params = new BasicHttpParams();
//params.setParameter("data", auth);
HttpClient httpclient = new DefaultHttpClient(params);

HttpPost httpPost = new HttpPost("http://project.chippy.ch/upload.php");

List<NameValuePair> postParams = new ArrayList<NameValuePair>();
postParams.add(new BasicNameValuePair("data", auth.toString()));

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(postParams);
entity.setContentEncoding(HTTP.UTF_8);
httpPost.setEntity(entity);

被要求代替

HttpClient httpclient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost("http://project.chippy.ch/upload.php");

String json = "";

json = auth.toString();

StringEntity se = new StringEntity(json);
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httpPost.setEntity(se);

httpPost.setHeader("User-Agent", "WalkingTourCreator/1.0");
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
