Hey I try to send a HttpPost to an special Device in a local network over wifi. If I try the same code on a simple Java application it will work, but If I try the same code on android I am not able to send the HttpPost.
String uri = "http://192.168.3.201:8080/remote/json-rpc/getPeripherals";
Log.i("uri", uri);
String requestBody = "{\"jsonrpc\":\"2.0\",\"method\":"
+ "\"configclient_homedevices/getPeripherals\",\"id\":"
+ "\"1349942076918\",\"params\":[]}";
Log.i("uri", uri);
String contentType = "application/json";
String userpassword = "foo:foo";
String encode = Base64.encodeToString(userpassword.getBytes(),
Base64.URL_SAFE | Base64.DEFAULT);
try {
URL url = null;
url = new URL(uri);
connection = (HttpURLConnection) url.openConnection(Proxy.NO_PROXY);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Authorization", "Basic" + encode);
connection.setRequestProperty("Content-Type", contentType);
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Length",
"" + Integer.toString(requestBody.getBytes().length));
connection.setUseCaches(true);
connection.setDoInput(true);
DataOutputStream out = null;
out = new DataOutputStream(connection.getOutputStream());
out.write(requestBody.getBytes());
out.flush();
out.close();
} catch (IOException ioE) {
connection.disconnect();
ioE.printStackTrace();
}
// connection.connect();
try {
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
Log.i("Status", toString().valueOf(connection.getResponseCode()));
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while ((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
this.response = response.toString();
Log.i("Response", response.toString());
} else {
Log.i("Status", toString().valueOf(connection.getResponseCode()));
Log.i("Status-message", connection.getResponseMessage());
connection.disconnect();
}
} catch (IOException e) {
e.printStackTrace();
}
this function is in a subclass which extends from AsyncTask. In the Manifest I enabled the Permission.INTERNET
<uses-permission android:name="android.permission.INTERNET" />
The result is:

The Exception is thrown at
out = new DataOutputStream(connection.getOutputStream());
I found a solution for my Issue. The Issue was a fixed IP adress in the url after changing this I received a Status Code 400 Bad Request. This issue I got before I switched the request to a async task subclass. The solution for the Bad Request I found in the wireshark protocol. The Client send 2 Hypertext transfer protocols in one http Post. This caused by the android.Base64.encode() methode. The encoder inserted a /n after encoding the user:password string. In this case the client sent one http with only basic auth and a second with the rest the body without the basic auth. So the server could not read the request.
To change this you should write android.Base64.encode(NO_WARP) this Flag will encode the username:password right.
