Thanks for the quick response, Arne. I have done as you suggested,
using the REST API and I was able to get the Viewer Id and Username.
However, I think I am not extracting the JSON data in the most
efficient manner. I'm using a URLConnection with a BufferedReader,
and then splitting the string into substrings delimited by the "-
character. My code follows:
public void doGet(HttpServletRequest req, HttpServletResponse
resp)
throws IOException {
session = req.getSession(true);
String viewerId = "";
String userName = "";
Logging thisLog;
String cookieName = "fcauth" + "15569016775267298719";
Cookie cookies [] = req.getCookies();
Cookie authCookie = null;
if (cookies != null) {
for (int i=0; i<cookies.length; i++ ) {
if (cookies[i].getName().equals(cookieName)) {
authCookie = cookies[i];
String cookieStringValue =
authCookie.getValue();
session.setAttribute("fcauth_token",
cookieStringValue);
String restString =
"http://www.google.com/friendconnect/api/
people/@me/@self?fcauth=" + cookieStringValue;
String inputLine = "";
URL restUrl = new URL(restString);
URLConnection restCon =
restUrl.openConnection();
BufferedReader restRead = new
BufferedReader(
new
InputStreamReader(restCon.getInputStream()));;
try {
inputLine = restRead.readLine();
String delim = "\"";
String[] tokens =
inputLine.split(delim);
viewerId = tokens[5];
userName = tokens[tokens.length
- 2];
thisLog = new Logging("New
Member: " + userName + " " +
viewerId, true);
} catch (Exception e) {
//
}
break;
}
}
}
Is there a more efficient way of extracting the JSON data?
Thanks again for the help,
Chris
