Re: [Htmlparser-user] Cookie

[Bob L. <bob...@ya...>]

In order to send cookies in your Http requests, all
you need to do is set the Cookie HTTP Header in the
URL Connection.  

Generally what I've done is first create a
HttpURLConnection, create some Cookie objects that are
needed, and set the HTTP Header using those objects
(See below for code to format the header value).  

Then I'll create the Parser using the URLConnection
something like this:

        DefaultHTMLParserFeedback feedback
            = new
DefaultHTMLParserFeedback(DefaultHTMLParserFeedback.DEBUG);

        HTMLReader reader = null;
        HTMLParser parser = null;
        String charset =
HttpUtil.getCharacterSet(urlConn);

        InputStreamReader isr
            = new
InputStreamReader(urlConn.getInputStream(), charset);
        reader = new HTMLReader(isr, 8192);
        parser = new HTMLParser(reader, feedback);

The HttpUtil.getCharacterSet method used above is
basically just taken from the method of the same name
in the HTMLParser class.  That method is protected, so
I had to duplicate it elsewhere.  


    /** set cookies to send in a HttpURLConnection<br>
     * This method should only be called before any
parameters are posted
     * and before the connection is made.
     * @param urlConn the HttpURLConnection to send
the cookies through
     * @param cookies the cookies to send
     */
    public static void postCookies(HttpURLConnection
urlConn, Cookie[] cookies)
    {
        if ((cookies == null) || (cookies.length ==
0))
        {
            return;
        }

        String[] cookieHeaders = new
String[cookies.length];

        urlConn.setRequestProperty("cookie",
generateCookieHeader(cookies));
    }

    /** generate a HTTP cookie header value string
from an array of cookies
     * @param cookies the cookies which should be set
in the header value
     * @return A string containing the HTTP Cookie
Header value
     */
    private static String
generateCookieHeader(Cookie[] cookies)
    {
        StringBuffer buf = new StringBuffer();

        for (int i=0; i < cookies.length;i++)
        {
            buf.append(cookies[i].getName());
            buf.append("=");
            buf.append(cookies[i].getValue());
            if (i+1 != cookies.length)
            {
                buf.append("; ");
            }
            else buf.append(" ");
        }

        return buf.toString();
    }
