I'm making a Php Webservice to read the OutputStream from a httpurlconnection. I have a android app that creates the httpurlconnection to the website and writes a json string to the OutputStream. Now I want to read/get that json with the Webservice. But I always get this error:
failed to open stream: HTTP request failed! HTTP/1.1 508 Loop Detected
I will give all the information about my application. If someone knows a better way to send and receive the data, always welcome!
My android application sends the data when there is an onclick event and then uses a AsyncTask. here's the code:
public void clickbuttonRecieve(View v) {
MyAsync performBackgroundTask = new MyAsync();
performBackgroundTask.execute();
}
protected Void doInBackground(Void... tmps) {
try {
// instantiate the URL object with the target URL of the resource to
// request
URL url = new URL("http://bomatec.be/webservice2.php");
// instantiate the HttpURLConnection with the URL object - A new
// connection is opened every time by calling the openConnection
// method of the protocol handler for this URL.
// 1. This is the point where the connection is opened.
HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
// set connection output to true
connection.setDoOutput(true);
// instead of a GET, we're going to send using method="POST"
connection.setRequestMethod("POST");
// instantiate OutputStreamWriter using the output stream, returned
// from getOutputStream, that writes to this connection.
// 2. This is the point where you'll know if the connection was
// successfully established. If an I/O error occurs while creating
// the output stream, you'll see an IOException.
OutputStreamWriter writer = new OutputStreamWriter(
connection.getOutputStream());
// write data to the connection. This is data that you are sending
// to the server
// 3. No. Sending the data is conducted here. We established the
// connection with getOutputStream
JSONObject data = new JSONObject();
data.put("user", "12");
data.put("lat", "50.8");
data.put("lng", "4.3");
String json = data.toString();
writer.write("json=" + json);
// Closes this output stream and releases any system resources
// associated with this stream. At this point, we've sent all the
// data. Only the outputStream is closed at this point, not the
// actual connection
writer.close();
// if there is a response code AND that response code is 200 OK, do
// stuff in the first if block
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
// OK
// otherwise, if any other status code is returned, or no status
// code is returned, do stuff in the else block
} else {
// Server returned HTTP error code.
}
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (JSONException e) {
e.printStackTrace();
return null;
}
}
}
My webservice app contains the following code :
header('Content-Type: application/json');
$json = file_get_contents('http://bomatec.be/webservice2.php?');
$obj = json_decode($json);
echo json_encode(array('json'=>$obj));
echo $json;
When I run the webserwice, example :
http://bomatec.be/webservice2.php?json={%22user_id%22:31,%22lat%22:50.78,%22lng%22:2}
I get following error :
{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}{"json":null}<br />
<b>Warning</b>: file_get_contents(http://bomatec.be/webservice2.php?): failed to open stream: HTTP request failed! HTTP/1.1 508 Loop Detected
in <b>/home/bomate1q/public_html/webservice2.php</b> on line <b>15</b><br />
{"json":null}
I don't know how to solve this. I lost myself in it.
