I'm trying to design an app that can communicate with my router programmatically using the same endpoints as the web interface (there's a demo on TP-Link's website). My router is a TP-Link TD-W8980, if that matters.
The format appears to be very difficult to decipher. Here is a request which obtains the data for the status part of my app. This can obtain a valid response from the router but I'm not sure why!
I'm especially confused by the #0,0,0,0,0,0#0,0,0,0,0,0] part of the response. It's the only part I haven't managed to work out but I think I recall reading it's to do with the stack?!?

If it helps, the names in capitals (e.g. SYS_MODE) is the name of the section. The number after the ] is a counter stating the section number (sections can be in any order). The final number following the , is the number of parameters that follow in this section.
There are also request types for each section. In the example above, the URL is http://192.168.1.1/cgi?1&1&1&1&5&5&5. As you can see the two main request types are 1 and 5.
Here is an example response from the server. As you can see, some of the sections can be returned more than once, which makes the first number of the six zeros increment each time.

I would appreciate any explanation of this format and if it appears anywhere else on the web. I've never seen such a system before!
My code used to work, it does not work anymore, I tried troubleshooting and can't figure out why.
I have this piece of code in my PHP:
$android_id_01 = $_GET['pmysql_room_id'];
$android_id_02 = "";
$f = fopen("00_android_id_01.txt", "w");
fwrite($f, print_r($android_id_01, true));
fclose($f);
$f = fopen("00_android_id_02.txt", "w");
fwrite($f, print_r($android_id_02, true));
fclose($f);
For troubleshooting I created two android IDs ($android_id_01 and $android_id_02) which are both empty (The first one is From Android and the second one I created directly from PHP).
Now when I launch my Android device, the PHP file is executed from server side and both the text files are created empty and identical. Now my code only works when I use $android_id_02 and not $android_id_01 from the code below:
if ($android_id == '')
{
//my code
}
(Yes when I use either one of the $android_id_01 OR $android_id_02 I rename it to $android_id and comment out the other one)
My question is, although this was working yesterday, why does it work with $android_id_02 = ""; and not $android_id_01 = $_GET['pmysql_room_id']; even though they are both empty????
I don't know what changed from yesterday to today.
Ok after a bit of troubleshooting I found a solution, strange though.
On the server side "display_errors" under PHP settings must be turned off. Somehow having this on interferes with the json_encode sent back to android client. (even though my code is not generating any errors)
I am creating one chatting application which will work on both iOS and Android platform. Sometimes 'both' subscription is not received at both end. Can anyone tell me what can be the possible issue?
===================== For iOS =====================
Sending request,
XMPPJID *XMPPJIDObj=[XMPPJID jidWithString:aStrOtherJabberId];
[appDelegateObj.xmppRoster addUser:XMPPJIDObj withNickname:nil];
Accepting request,
[appDelegateObj.xmppRoster acceptPresenceSubscriptionRequestFrom:aReceiverJID andAddToRoster:TRUE];
Removing user,
[appDelegateObj.xmppRoster removeUser:[XMPPJID jidWithString:aPresenceObj.userJabberID]];
===================== For Android =====================
Sending request,
Roster.setDefaultSubscriptionMode(SubscriptionMode.manual);
myApp.getXmppConnection().getRoster().createEntry(visitorJabberId, visitorUserName, null);
Accepting request,
final Presence presence1 = new Presence(Type.subscribed);
presence1.setFrom(myApp.getUserJabberId());
presence1.setType(Type.subscribed);
presence1.setTo(visitorJabberId);
myApp.getXmppConnection().sendPacket(presence1);
myApp.getXmppConnection().getRoster().createEntry(visitorJabberId, visitorUserName, null);
Removing user,
final RosterPacket rosterPacket = new RosterPacket();
rosterPacket.setType(IQ.Type.SET);
final RosterPacket.Item item = new RosterPacket.Item(visitorJabberId, null);
item.setItemType(RosterPacket.ItemType.remove);
rosterPacket.addRosterItem(item);
myApp.getXmppConnection().sendPacket(rosterPacket);
Hi Leena for the iOS we have used save thing but I think you have forgot some thing. The actual flow is call add user method of roster class then call subscribe method with subscription value YES and finally send presence tag with subscribe type to the serve. Following are the code here I used XMPPSharedPreference singleton class rather than appdelegate. Hope this will work for you...
XMPPJID *newBuddy = [XMPPJID jidWithString:JIDString];
[[XMPPSharedPreference sharedPreferences].xmppRoster addUser:newBuddy withNickname:#"nicknameValue"];
[[XMPPSharedPreference sharedPreferences].xmppRoster acceptPresenceSubscriptionRequestFrom:newBuddy andAddToRoster:YES];
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
[presence addAttributeWithName:#"to" stringValue:JIDString];
[presence addAttributeWithName:#"type" stringValue:#"subscribe"];
[[self xmppStream] sendElement:presence];
When you add a user to your roster you have to make sure you also subscribe to the friend's presence. That completes the cycle.
So, for iOS for example, you're adding a friend to roster like this:
[appDelegateObj.xmppRoster addUser:XMPPJIDObj withNickname:nil];
But you need to do use this instead:
- (void)addUser:(XMPPJID *)jid withNickname:(NSString *)optionalName groups:(NSArray *)groups subscribeToPresence:(BOOL)subscribe
and make sure you set subscribe to YES
Or, you could keep the code you have but manually subscribe to the user's presence by doing this:
[appDelegateObj.xmppRoster subscribePresenceToUser:XMPPJIDObj]
Let me know how that works out for you.
I need to work with a TCP socket over TLS for an app I'm working on. I've been through dozens of examples and while I have no problem getting through the handshake, I can't seem to read the input stream through any means (tried a lot, including readline(), reading to character array, etc). every time I try, the app freezes on that spot. If I debug, it never goes to the next line of code.
In an attempted solution, I decided to move over to using an SSLEngine, since that's supposed to be the Java 1.5 answer to java.nio for SSL. However, I have found one example (here: http://docs.oracle.com/javase/7/docs/technotes/guides/security/jsse/samples/sslengine/SSLEngineSimpleDemo.java) which is more than a little confusing to me, and I've not been successful implementing it. When I try, the unwrap() call yields an empty buffer, where I know (from using OpenSSL on the command line) that the service in question pushes data back down the pipe.
Suggestions are welcome, I've burned way too much time on this already. Here's the relevant code:
SSLEngine engine = sslContext.createSSLEngine(uri.getHost(), uri.getPort());
engine.setUseClientMode(true);
engine.beginHandshake();
SSLSession session = engine.getSession();
int bufferMax = session.getPacketBufferSize();
int appBufferMax = session.getApplicationBufferSize() + 50;
ByteBuffer cTo = ByteBuffer.allocateDirect(bufferMax);
ByteBuffer sTo = ByteBuffer.allocateDirect(bufferMax);
ByteBuffer out = ByteBuffer.wrap(sessionId.getBytes());
ByteBuffer in = ByteBuffer.allocate(appBufferMax);
debug("sending secret");
SSLEngineResult rslt = engine.wrap(out, cTo);
debug("first result: " + rslt.toString());
sTo.flip();
rslt = engine.unwrap(sTo, in);
debug("next result" + rslt.toString());
This implementation is missing some key pieces. Namely the handshake can bounce between several states NEED_WRAP, NEED_UNWRAP, NEED_TASK to negotiate a connection. This means you cannot just call one and then the other. You will need to loop over the states until a handshake has completed.
while (handshaking) {
switch (state) {
case NEED_WRAP:
doWrap();
break;
case NEED_UNWRAP:
doUnwrap();
break;
case NEED_TASK:
doTask();
break;
}
}
A full working example of Java SSL and NIO
Now that said, you should be aware the SSLEngine on Android is broken. Google recommends using threads and blocking sockets according to that thread.
I have written something to make using SSLEngine easier. It can be used with NIO or for other use cases. Available here SSLFacade
unwrap() can yield an empty buffer if what was unwrapped was an SSL handshake message or alert, rather than application data. There's not enough information here to say more. What was the engine status afterwards?
beginHandshake does not proceed the handshake, it is just used to inform the SSLEngine that you want to perform the handshake for the next calls to wrap/unwrap.
It's useful when you want to do another handshake. For the initial one, it is not needed as the first call to wrap will initiate the handshake.
Besides, you have to check the result of the wrap and unwrap methods to know if all the data has been correctly encoded. It can happen that you have to call the methods several times to process all the data.
The following link might help:
http://onjava.com/onjava/2004/11/03/ssl-nio.html
Or this question:

Is there anyone there who can tell me how i can send a string ("example") to an ipadress on a local network via wifi in as3 on air on adroid.
Thanks in advance!

I'd imagine you can just use the HTTPService class or URLRequest (if you're not using Flex) the code would be something like this:
var urlRequest:URLRequest = new URLRequest("http://192.168.1.100/test.php");
var urlVariables:URLVariables = new URLVariables();
urlVariables.testVarName = "example";
urlRequest.data = urlVariables;
sendToUrl(urlRequest);
alternatively if you want to listen to the response use a URLLoader, if you're going with Flex HTTPService basically wraps up this functionality into a single class for that just create one set the url and call myHTTPService.send([optional params if not on data]);
Let me know if this doesn't work out and what errors you get or behavior, haven't actually tried yet within an Android device but if there's variance in the approach I'd like to know as well.
So php file is resident on the computer your sending the mesange to?
