使用 httpurlconnection 登录 Facebook

Question

I'm trying to login to facebook using httpurlconnect. I think i need to get the cookie from facebook.com/ajax/bz and then pass it along with my login attempt but maybe not. The response just takes me back to the login page and I never log in. Can someone help me get this to log in?

I do not want to use the official API.

private String getRequestCookie() throws IOException {
    // URL myUrl = new URL("http://www.hccp.org/cookieTest.jsp");
  /*  URLConnection urlConn = null;
    try {
        urlConn = url.openConnection(currentProxy);
        urlConn.connect();
    } catch (IOException e) {
        e.printStackTrace();
    }*/

    String cookies = "";
    URL myUrl = new URL("https://www.facebook.com/ajax/bz");
    URLConnection urlConn = myUrl.openConnection();
    urlConn.connect();
    String headerName=null;
    for (int i=1; (headerName = urlConn.getHeaderFieldKey(i))!=null; i++) {
        if (headerName.equals("Set-Cookie")) {
            String cookie = urlConn.getHeaderField(i);
            cookie = cookie.substring(0, cookie.indexOf(";"));
            String cookieName = cookie.substring(0, cookie.indexOf("="));
            String cookieValue = cookie.substring(cookie.indexOf("=") + 1, cookie.length());
            cookies = cookies+cookieName+"="+cookieValue+"; ";
            //cookieNameList.add(cookieValue);
            System.out.println("da cookies:" + cookies);

            return cookies;
        }
    }
    // must have failed yo
    cookies = "failed";
    return cookies;
}

It doesn't matter that you want to do it; according to the Automated Data Collection Terms , it's not allowed. You app/server can be blocked. Don't do this. Instead, just use the Graph API and all documented features.
