Once again I need your help with an issue:
I'm currently implementing an app, which communicates with a network electrical-socket. Therefore I'm sending a "selfmade" http-request. This works fine as long as I'm using WiFi or having o2 as provider (I'm living in Germany). But as soon as I use mobile internet with Vodafone, I get bullshit as response.
Here is, what I do:
checkDosenTimer: function(){
var header =
"GET /dd.htm?DD" + dosenId + " HTTP/1.1\r\n"
+"Host: " + ip + "\r\n"
+"Connection: keep-alive\r\n"
+"Authorization: Basic " + Base64.encode(userName+":"+password) + "\r\n"
+"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n"
+"User-Agent: Mozilla/5.0 (Linux; Android 4.1.1; HTC One S Build/JRO03C) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.90 Mobile Safari/537.36\r\n"
+"Referer: http://" + ip + "mobile.htm\r\n"
+"Accept-Encoding: gzip,deflate,sdch\r\n"
+"Accept-Language: de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4\r\n"
+"Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3;\r\n\r\n";
var that = this;
cordova.exec(
function(succ){
that.processTimerResult(succ);
},
function(err){
console.log("Error bei HTTPController sendMessage: "+err);
},
"HttpController",
"sendMessage",
[header,'',ip,httpPort]
);
}
So what I do is, I set up my header in JavaScript and passing it to the Java method sendMessage within the HttpController, which has the following form:
private void sendMessage(JSONArray args,
CallbackContext callbackContext)
throws JSONException {
String header = args.getString(0);
String body = args.getString(1);
String routerIp = args.getString(2);
int routerPort = args.getInt(3);
Tcp tcp = new Tcp();
String result = tcp.sendMessage(header,body,routerIp,routerPort);
callbackContext.success(result);
}
Finally, we arrive in the method sendMessage in Tcp:
public String sendMessage(String header,String body, String routerIp, int routerPort) {
String respond = "";
Socket socket = null ;
try {
//Create socket
socket = new Socket(routerIp, routerPort);
socket.setSoTimeout(10000);
//Send header
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(),"UTF-8"));
// You can use "UTF8" for compatibility with the Microsoft virtual machine.
wr.write(header);
wr.flush();
//Send data
wr.write(body);
wr.flush();
// Response
BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
while((line = rd.readLine()) != null)
respond += line;
} catch (IOException e) {
e.printStackTrace();
} catch (Error e){
e.printStackTrace();
}finally{
final Pattern p = Pattern.compile("errorCode");
final Matcher m = p.matcher(respond);
if(!(m.find())){
return respond;
}else{
return "no Respond from " + routerIp + " on Port:" + routerPort;
}
}
}
First of all: thank you for reading so far :-)
I made shure, that the header-string in the Tcp class keeps the same. But the response which arrives at the Tcp class differs depending on the provider. With Vodafone, the Response looks like:
The expected result ist something like:
I guess that my provider (=vodafone) manipulates my GET-request for some reasons. Is this assumption possible? Is there a way how to get arround that?
