Question

If it’s any help, there is also a similar class in C#’s WebRequest. Although I do not want it in java or .NET, i am wondering how to implement this in native C/C++ code (for windows).

for reference:

try {  URL url=new URL('http://google.ca'); HttpURLConnection con=(HttpURLConnection)url.openConnection(); con.connect(); int code = con.getResponseCode(); System.out.println(code);  } catch (MalformedURLException e) { System.err.println('Error reading URL.'); } 

prints out:

200 

meaning ‘OK’

I understand I probably need to use sockets and send a User-Agent string, but I haven’t a clue where to begin. Whenever I learn a new language the first thing I like to do is try porting my code to it, but this one has stumped me.

Any help is appreciated

Answer 1

There is no HTTP support in standard C library.

So you have two options – use 3rd-party HTTP library, such ar libcurl, or handle HTTP yourself:

• open socket
• resolve hostname
• connect to server
• build HTTP request
• send request to server
• receive HTTP response
• parse response and get response code from it.
