Wireshark · Wireshark-users: [Wireshark-users] Making a Web Request is failing with 403 Request Forbidden

[Vineet Mishra <clearmidoubt@xxxxxxxxx>]

Hi All,

I am making web server call to a website for Shortening the links, that is bit.ly but recieving a 403 Request Forbidden.

Although if I use their webpage to short the web link its working good.

Can any body tell me what might be the reason for such a vague behavior.

Here is the code included.

String url = "" href="https://bitly.com/shorten/" target="_blank">https://bitly.com/shorten/";

StringBuffer response;

try {

URL obj = new URL(url);

HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();

 

//add reuqest header

con.setRequestMethod("POST");

con.setRequestProperty("User-Agent", "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.22 (KHTML, like Gecko) Ubuntu Chromium/25.0.1364.160 Chrome/25.0.1364.160 Safari/537.22");

con.setRequestProperty("Accept-Language", "en-US,en;q=0.8");

con.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");

con.setRequestProperty("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3");

con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

con.setRequestProperty("Host", "bitly.com");

String urlParameters = "url="" href="http://bit.ly/1f3aLrP&ie=utf-8&oe=utf-8&gws_rd=cr&ei=sKlwUvPbN8j-rAf-5IDwAQ&basic_style=1&classic_mode=&rapid_shorten_mode=&_xsrf=a2b71eaf499c4690a77a21d3c87e6302" target="_blank">http://bit.ly/1f3aLrP&ie=utf-8&oe=utf-8&gws_rd=cr&ei=sKlwUvPbN8j-rAf-5IDwAQ&basic_style=1&classic_mode=&rapid_shorten_mode=&_xsrf=a2b71eaf499c4690a77a21d3c87e6302";

 

// Send post request

con.setDoOutput(true);

DataOutputStream wr = new DataOutputStream(con.getOutputStream());

wr.writeBytes(urlParameters);

wr.flush();

wr.close();

 

int responseCode = con.getResponseCode();

System.out.println("Response Code : " + responseCode);

 

BufferedReader in = new BufferedReader(

       new InputStreamReader(con.getInputStream()));

String inputLine;

response = new StringBuffer();

 

while ((inputLine = in.readLine()) != null) {

response.append(inputLine);

}

in.close();

System.out.println(response.toString());

} catch (MalformedURLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (ProtocolException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

Hoping for your response.

Thanks!
