How to read form data from headers

Question

In my current application (A), I redirect the user to another website (B) where the user logs into his account and completes some activity, and now on the website (B) there is a button to return my application (A ), redirection occurs by placing SAMLResponse .

When a user clicks on this button, the user returns to my application (A) with a specific unique user ID assigned by this website (B) in the “ Form Data ” header information. In either case, website B also publishes SAMLResponse as form in the request.

How to read this request information in php and java?

Part of the "form data" is unclear, but you can print the source code of the desired URL on the console as follows:

 import java.io.*; import java.net.*; public class Client { public String getHTML(String urlToRead) { URL url; HttpURLConnection conn; BufferedReader rd; String line; String result = ""; try { url = new URL(urlToRead); conn = (HttpURLConnection) url.openConnection(); conn.setRequestMethod("GET"); rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); while ((line = rd.readLine()) != null) { //basically makes a huge string result += line; } rd.close(); } catch (Exception e) { e.printStackTrace(); } return result; } public static void main(String args[]) { Client c = new Client(); System.out.println(c.getHTML("YOUR URL HERE")); //prints source code to console } //from here, you need to know which item you want to do is at which index of the string }
