http request through java code

[swapnel surade]

Hi,

I'm building an application in which I'm sending HTTP request through java code.

 

 String requestUrl = "http://127.0.0.1:2151/PCTClient?action=108";
        HttpURLConnection con=null;
        try {
            URL url = new URL(requestUrl.toString());
            con=(HttpURLConnection)url.openConnection();              
            con.getResponseMessage();
            con.disconnect();

        } catch (IOException e) {
            e.printStackTrace();
        }
   

but when I'm listening in thread at given port I'm getting 2 request for single button click.

is there any problem in the code...

thanks

I don't see anything obviously wrong. Does this code get called twice?

While it is not hard to get a basic GET or POST to work using just the Java libraries, there is a lot more to doing it properly and completely.

Things like "chunked" responses must be supported, and my code was in production for several months before I even knew that it could happen.

I strongly recommend just using the Apache Http client library. Its easy to use, does all the edge cases properly, handles normal and SSL, etc.
