Fetch a page from GoogleTag(s): Networking
You can't directly fetch a page from Google because a check is made (by Google) to restrict access to "real" browser so a "403" HTTP code is returned to your Java program.
You need to fool Google by pretending to be a legitimate browser.
Note : You may want to take a look at http://www.google.com/apis/ to learn how to interact with Google via the official API's.
String search= "What you want to search for"; String google="http://www.google.ca/search?q=" + search + "&hl=en&ie=UTF-8&oe=UTF8"; URL urlObject = new URL(google); URLConnection con = urlObject.openConnection(); con.setRequestProperty ( "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" ); webData = new BufferedReader(new InputStreamReader(con.getInputStream())); ...
As seen above, you can directly override the HTTP header. Another way is to start the program with a modified System.property http.agent.
or in your program
>java "-Dhttp.agent=Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" MyClass
System.setProperty ("http.agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
