Question

i have a JSONObject which i want to POST to a server.

Here is the Code:

JSONObject obj = new JSONObject();
for(int k = 0; k<len;k++){
    obj.put("nachrichten_ids", params[k]);
}
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("xxxxx");
HttpEntity entity;
StringEntity s = new StringEntity(obj.toString());
s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
entity = s;
httpPost.setEntity(entity);
HttpResponse response;
response = httpClient.execute(httpPost);

By doing Log.i(“TEST”,obj) i get the JSON object:

{“nachrichten_ids”:”[2144,2138]”}

That data is send to the server. But i cant access it:
There is no $_POST index. (PHP)

How to set a index, so that i can access the json object, like $_POST[‘nachrichten_ids’].
I had to work with that data then e.g with php json_decode()

Any idea ?

Thanks

Try putting your jSON object into a namevaluepair. The name of the pair you add is the name you should use when reading it on the web. For example here I will get Password by calling $_POST[‘Password’].

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

    nameValuePairs.add(new BasicNameValuePair("Password", "My password"));
    nameValuePairs.add(new BasicNameValuePair("Mail", "My mail"));

    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

    // Execute HTTP Post Request
    BasicHttpResponse response = (BasicHttpResponse) httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();
